Rug pull crypto : de quoi parle-t-on ?

Vous avez peut-être déjà vu passer le terme rug pull dans l’univers des cryptomonnaies. Mais qu’est-ce que ça veut dire exactement ? Contrairement aux schémas de type pump and dump, un rug pull est une technique frauduleuse particulièrement répandue dans les coins et tokens peu connus.

Définition d’un rug pull

Un rug pull est une escroquerie dans laquelle des développeurs créent un projet crypto puis disparaissent avec les fonds des investisseurs.

Cela se produit souvent dans le monde de la finance décentralisée (DeFi), notamment sur les échanges décentralisés (DEX). Voici comment cela fonctionne :

1. Des développeurs créent un nouveau token et le listent sur un DEX.
2. Ils le lient à une cryptomonnaie populaire comme l’Ethereum.
3. Pour attirer les investisseurs, ils injectent temporairement beaucoup de liquidités dans le pool et lancent une campagne marketing sur les réseaux sociaux (Twitter, Telegram, etc.).
4. Une fois qu’un grand nombre d’utilisateurs échangent leurs ETH contre ce nouveau token, les développeurs retirent toutes les liquidités, faisant chuter la valeur à zéro et empochant les fonds.

Ce type d’arnaque touche principalement les projets très récents, jamais des projets établis comme Bitcoin ou Ethereum.

Pourquoi les DEX sont vulnérables ?

Les rug pulls sont particulièrement fréquents sur les DEX car ils ne nécessitent aucun audit préalable pour lister un token. Et comme créer un jeton ERC-20 sur Ethereum est simple et peu coûteux, cela facilite les choses pour les arnaqueurs.

Quels signaux doivent alerter ?

Même si les rug pulls sont plus rares que d’autres types de fraudes, certains signes avant-coureurs doivent vous mettre la puce à l’oreille :

• Liquidité suspecte : Assurez-vous que le projet a une liquidité verrouillée pour une durée donnée. Les projets sérieux verrouillent généralement leur pool.
• Hausse fulgurante : Un token qui prend x50 en 24h, c’est suspect. Ce type de hausse provoque un effet FOMO destiné à piéger de nouveaux investisseurs.
• Répartition des tokens : Un projet est souvent considéré comme "unruggable" si l’équipe de développement ne détient pas une majorité des tokens. En d'autres termes, pas de grande quantité entre les mains des créateurs = moins de risque de fuite.

Est-ce illégal ?

En théorie, oui. En pratique, le droit peine à suivre l’évolution rapide de la crypto. Le manque de réglementation précise rend l’identification et la poursuite des responsables difficile. Résultat : beaucoup de rug pulls restent impunis.

Exemple : le rug pull du Squid Game

L’un des rug pulls les plus médiatisés reste celui du Squid Game Token, en 2021.

Le token, inspiré de la célèbre série Netflix, a vu sa valeur grimper jusqu’à 2 861 $ par coin. Sauf qu’au sommet du buzz, le site officiel a été supprimé, les créateurs introuvables, et la liquidité a disparu. En quelques instants, le token est passé de l’euphorie à une valeur quasi nulle, tandis que les créateurs repartaient avec plus de 3,3 millions de dollars.

La manipulation allait encore plus loin : les développeurs avaient intégré un mécanisme anti-vente, empêchant les détenteurs de revendre leurs tokens. Un plan orchestré dès le départ.

En résumé

Les rug pulls ne sont pas les arnaques les plus fréquentes, mais elles existent et peuvent coûter cher. Le mieux est de rester vigilant face aux nouveaux projets qui font beaucoup de bruit en peu de temps. Privilégiez toujours les projets établis et prenez le temps d’analyser la solidité d’un token avant d’investir.

Dans l’univers crypto, mieux vaut prévenir que guérir.

We’ve covered what Proof of Work and Proof of Stake is, but what is PaaS?

In this article, we’re making this rather complicated-sounding term easy to understand as we explore where it came from, what it means, and why it’s likely to keep popping up in the crypto realm. 

What Is PaaS?

PaaS stands for Platform as a Service and refers to a cloud delivery service that uses third-party cloud service providers. “As a service” indicates that the cloud computing service is provided by a third party, rather than the user having to manage their own hardware and software.

PaaS providers offer a range of services, including operating systems, databases, middleware, and other software development tools. PaaS offerings can be used for both cloud-native and hybrid cloud applications.

PaaS solutions are popular among software developers and businesses looking to migrate their applications to the cloud. They provide an application development platform that can be used to build and deploy applications quickly and easily, without the need for specialized hardware or software.

Some of the key benefits of PaaS include reduced costs, faster deployment, and greater flexibility and scalability. PaaS providers offer a range of services, including operating systems, databases, middleware, and other software development tools. This allows users to develop, run, and manage applications without having to worry about the underlying infrastructure.

The History of PaaS

PaaS first appeared in 2005 as Zimki under the company Fontago. Zimki allowed users to build and deploy web services and applications through its code execution platform.

Billing was determined based on the number of JavaScript operations, the amount of web traffic and the total storage used, providing users with a much clearer cost structure than on other platforms. The platform was eventually shut down in 2008 by its parent company.

That same year the Google App Engine was launched allowing users to create web services and applications using languages like Go, PHP, Node.js, Java and Python.

Today, Google remains the biggest PaaS vendor in the world. 

How Does PaaS Work?

Instead of replacing its overall IT infrastructure and running these services in-house, PaaS streamlines access to its key services. This helps to reduce time in deployment as well as minimize startup costs. 

PaaS allows users to tap into resources and functions like capacity on demand, data storage, text editing, vision management and testing services despite being in geographically different locations. All while using a pay-per-use model. 

PaaS Offers Development Tools

PaaS, or Platform as a Service, is a cloud-based platform that provides users with access to the tools and resources needed to develop and run applications. Instead of replacing its overall IT infrastructure and running these services in-house, PaaS streamlines access to its key services, allowing users to easily tap into resources and functions like capacity on demand, data storage, text editing, vision management, and testing services. This pay-per-use model enables users to access the tools and resources they need without incurring the high costs of building and maintaining their own infrastructure.

PaaS technology offers a range of benefits for both developers and businesses, including the ability to easily integrate databases, manage infrastructure, and access data centers. This can provide a range of advantages, such as improved performance, enhanced security, and increased scalability.

PaaS technology providers also offer a range of services and support to their customers, including integration platforms and infrastructure management services. This can help businesses to quickly and easily integrate their applications with other systems and platforms, allowing them to take advantage of the benefits of PaaS without having to worry about the underlying infrastructure.

PaaS vs IaaS vs SaaS

PaaS, IaaS, and SaaS are all different models of cloud computing. PaaS, or Platform as a Service, provides access to the tools and resources needed to develop and run applications, while IaaS, or Infrastructure as a Service, offers access to the underlying infrastructure, including storage, networking, and computing power. SaaS, or Software as a Service, provides access to software applications over the internet.

These models differ in terms of what areas are handled on-site and which are handled by a third-party provider. For example, with PaaS, the infrastructure and operating system are managed by the provider, while the customer focuses on developing and deploying their own applications. With IaaS, the provider manages the infrastructure, while the customer is responsible for the operating system and applications. With SaaS, the provider manages everything, including the infrastructure, operating system, and applications.

Examples of companies that offer PaaS services include Amazon Web Services and the IBM Cloud, while IaaS providers include AWS, Microsoft Azure, and Google Cloud. Dropbox, Salesforce, and Google Apps are examples of SaaS providers.

These models offer advantages to businesses and developers looking to enter the cloud computing space. For example, PaaS offers the ability to focus on app development without worrying about the underlying infrastructure, while IaaS and SaaS provide access to cloud resources and the ability to quickly deploy and scale applications. These models can also be used to build communications platforms and other mobile applications, providing access to the necessary infrastructure and resources.

PaaS Provider In Blockchain

The use of PaaS technology, or Platform as a Service, within the blockchain industry is becoming increasingly popular. While blockchain platforms themselves are not typically structured in a PaaS way, the concept of BPaaS, or Blockchain Platform as a Service, offers businesses and enterprises the opportunity to focus on the development of software and other services for customers.

BPaaS provides numerous advantages for companies looking to enter the blockchain space. It allows businesses to leverage the power of cloud-based infrastructure and resources to develop and deploy applications without the need to manage their own hardware and software.

PaaS providers like Amazon Managed Blockchain and the IBM Blockchain Platform are leading the way in offering BPaaS solutions to businesses. These platforms offer a range of tools and resources for application development, including integrated development environments (IDEs), code libraries, and APIs. This allows developers to focus on building and deploying their own blockchain-based applications without worrying about the underlying infrastructure.

Overall, the use of PaaS in the blockchain industry offers numerous benefits, including reduced production costs, streamlined deployment, and the ability to easily integrate specific AI capabilities into applications. This makes it an attractive option for businesses looking to enter the blockchain space.

Crypto lending might be the hot new product in the cryptocurrency space, but before you dive in be sure to first understand what it entails. The concept grew great traction with the rise of the decentralized finance (DeFi) movement, with platforms offering users high yields for borrowing crypto assets. 

Let’s get started with what crypto lending is, and then explore how the product works. 

What is crypto lending?

Crypto lending is a traditional banking service curated to the crypto world. With the DeFi space remains largely unregulated, many crypto exchanges and other platforms have started offering these services, with added security. 

Crypto lending involves a user lending crypto assets to a platform in return for interest, which allows other users to then borrow said crypto assets, paying interest on the amount borrowed. The platform will then take a small percentage of the interest paid. 

Depending on the platform and other factors, crypto lending platforms may be centralized or decentralized and offer exceptionally high-interest rates, with annual percentage yields (APYs) of 15% or more. With the interest rates being higher than traditional bank accounts, lenders gain access to much greater yields, increasing their returns. 

Another advantage to crypto lending is that users are still exposed to price gains in the market. Meaning that if you deposit your Bitcoin when it's worth $20,000 and the price rises in value to $50,000, you are still able to realize these returns and earn interest for the duration of the loan. 

Note that interest rates might fluctuate with market conditions on some platforms, increasing when the prices increase and decreasing when markets are down.

How does crypto lending work?

Cryptocurrency lending platforms function as middlemen connecting lenders to borrowers. Lenders deposit their digital currency into high-interest lending accounts, and borrowers utilize the lending platform to acquire loans. These systems then lend money utilizing the crypto that investors have provided them.

The platform controls its net interest margins by establishing the interest rates for both lending and borrowing.

Rates on platforms differ from cryptocurrency to cryptocurrency, some platforms might offer higher interest rates to lenders willing to commit to a certain time frame. There is no standard interest rate for cryptocurrencies, as each platform has its own set of rules.

Centralized crypto lending means putting your money in the hands of a corporation or other entity to manage and make the process easier. Accounts are created for borrowers and lenders, and loans may be requested by applicants.

Lenders and borrowers may connect their cryptocurrency wallets to a decentralized crypto lending protocol, ​​which uses smart contracts to automate the lender-borrower relationship. Smart contracts are automated digital agreements that execute once certain criteria is met. 

The advantages of crypto lending

There are several benefits to crypto lending when comparing it to a regular bank account.

Borrowers have access to these financial services without having to pass a credit check, making it more financially inclusive than traditional banking services. They are also exposed to lower interest rates than regular banking loans.

Lenders that give loans in the form of cryptocurrencies can make a lot more money from their crypto assets than savings accounts. It may also be a more adaptable choice to crypto staking, which requires users to lock up their cryptocurrency and submit it to a blockchain security method. Depending on the platform, lending usually gives users access to their funds.

The downside to crypto lending

The agreement with crypto loan companies is generally made on individual terms by institution borrowers. As interest rates vary across platforms and cryptocurrencies, each company is different.

There have been several cases where lending platforms have been hit by severe liquidity crisis, notably Celsius, Voyager Digital, and BlockFi. Glenn Huybrecht, COO of Cake DeFi, said, “Some lending providers have been very generous with low collateral requirements, which then puts them in hot water when one of their customer's defaults.”

Due to the ongoing regulation battles, these crypto services are also not backed by government safety nets, like the traditional banks are. However, some platforms do hold insurance and the necessary regulatory accreditations so be sure to seek one that has all of the above.

Closing thoughts

Crypto lending platforms differ greatly from one another so be sure to check each platform, their interest rates for all the various currencies supported, and if there are any lock-up periods or fees payable. 

Playing an important role in the adoption of Web3, Enjin provides a platform of software products designed to allow anyone to harness the power of NFTs (non-fungible tokens) through the development, trade, monetization, and marketing of blockchain assets. 

What is the Enjin platform?

The Enjin platform is an ecosystem of interconnected, blockchain-based gaming products designed for individuals, game developers and businesses to create, manage and trade virtual goods such as digital art, games, or virtual marketplaces using the Ethereum blockchain. Enjin aims to provide users with the tools to implement smart digital solutions for blockchain games within the gaming environment.

Through the platform's software development kits (SDKs) and APIs, users can build digital assets as well as seamlessly integrate them into their games and applications. 

Under the Enjin umbrella is the Enjin Network, a community gaming platform that allows users to create websites, chat, and host virtual stores. Over the course of a decade, the Enjin platform has accumulated over 20 million users.

Powering the ecosystem is the Enjin Coin (ENJ), a token used to back the value of NFTs and other assets minted on the platform. When an asset is minted it locks ENJ tokens into a smart contract and effectively removes the tokens from circulation.

It’s also worth noting that Witek Radomski, Enjin's co-founder and the brainchild behind the ERC-1155 Ethereum token standard, wrote the code for the first non-fungible token (NFT). By utilizing its cutting-edge technology, Enjin is revolutionizing the future of gaming and digital assets.

Who created Enjin?

Enjin was originally founded in 2009 as a gaming community platform by Maxim Blagov and Witek Radomski. Blagov took on the responsibility of being CEO and in charge of the platform's creative direction while Radomski took on the role of CTO, leading the technical development of the platform's products.

Following Radomski's interest in Bitcoin in 2012, the platform explored incorporating blockchain technology into its business model and embraced the world of tokenized digital assets.

Radomski went on to write the ERC-1155 token standard in June 2018, a token standard used for minting both fungible, semi-fungible and non-fungible tokens using the Ethereum network. This token standard is a critical building block in the platform’s design.

In 2017, the Enjin platform launched an initial coin offering (ICO), raising $18.9 million through ENJ token sales. A year later the project went live and in September 2019, the Enjin Marketplace was launched.

How does Enjin work?

The primary goal of the Enjin network is to facilitate the management and storage of virtual goods for games, anything from in-game currencies to unique in-game items. So, how does Enjin work? The process of creating and destroying these tokens involves five steps, as outlined below. 

• Purchase
  Developers purchase Enjin Coin. 
• Minting
  In-game items are designed and effectively minted with the appropriate amount of ENJ locked into a smart contract.
• Utilization
  Players use these tokens within the game.
• Trading
  Players trade the tokens between fellow players or on the internal or external marketplace.
• Melting
  Players sell the tokens for Enjin Coin, referred to as melting. The token is destroyed and Enjin Coin is released from the smart contract.

SDKs (software development kits) come into play here, with kits designed to fulfill certain functions, such as facilitating a payment platform or being wallet-focused. These kits are designed to minimize costs and simplify the process of creating these virtual goods. APIs (application programming interfaces) work alongside the SDKs to integrate these virtual goods (digital assets) into the game.

The Enjin platform utilizes JumpNet which is integrated with other products in the ecosystem, such as the Marketplace, Enjin Beam, and the Enjin Wallet to allow for gas-free transactions for ENJ and NFTs.

The Enjin ecosystem encompasses the Enjin smart wallet that allows players to store and trade their in-game items with ease. The Enjin wallet is designed to connect all the features, from managing inventory to conducting transactions and selling these tokenized digital assets for ENJ. 

What is the Enjin Coin (ENJ)?

Enjin Coin (ENJ) is the native token of the Enjin ecosystem. Built on the Ethereum blockchain and compatible with multiple gaming platforms, the Enjin Coin is an ERC-20 token that allows the in-game items created on the platform to be traded with real-world value. The ENJ token has a maximum supply of 1 billion coins.

The token also allows developers to mint these digital goods. The process requires the users to lock Enjin Coin (ENJ) into a smart contract that automatically assigns value to the in-game item. Players that later use these items can use them in the game, trade them or sell them for ENJ, equivalent to the original minting cost. Once sold, the item is destroyed (known as melting) and the ENJ that was locked in the smart contract is released to the seller.

How can I buy Enjin Coin?

Anyone can tap into the Enjin ecosystem by acquiring ENJ tokens through the Tap mobile app. Simply create an account and complete the verification process in order to gain access to your unique Enjin wallet, from where you can buy, trade and sell Enjin Coin. 

Fully licensed and regulated, Tap provides a secure and convenient means of managing your funds, allowing users to manage and store both crypto and fiat currencies in one location. With a wide range of supported currencies and services, Tap is revolutionizing the financial space.

Take advantage of the power of Enjin Coin on the Tap app - the ultimate platform to buy, sell or hold ENJ. With seamless integration and an intuitive interface, trading Enjin tokens has never been easier. Stay up-to-date with the latest market trends and keep your portfolio on track by monitoring the Enjin Coin price in real-time. 

In this article, we're covering what transaction fees are, and taking a look at which cryptocurrencies offer the lowest transaction fees.

While long-term traders are unlikely to get affected by transaction fees, short-term traders and people actively using cryptocurrencies are often plagued with excessive fee structures.

This complaint has led to layer 2 solutions, where transactions can most quickly and cost-effectively be executed, as well as new blockchain platforms entirely (as was the case when developers migrated away from Ethereum due to high transaction costs).

What are transaction fees?

Transaction fees are fees paid to the miner of the network to execute the transaction. While some networks differ in how they operate, transaction fees are consistent across the board. Looking at Bitcoin as an example, when a user sends BTC the transaction is entered into a pool of pending transactions known as a mempool. 

The miner will then pick up a batch of transactions and validate them, checking to see whether the original wallet does in fact have the funds to send and if the wallet addresses are valid. Once the transaction is executed, the data relevant to the transaction is added to a block, which is added to the blockchain chronologically. 

As compensation to the miner for their time and electricity, they earn a small crypto transaction fee from each transaction as well as a reward for adding the block, known as a miner's reward. This process also ensures the safety and integrity of the network.

When the networks are very busy, the cost of sending a transaction is increased. Users can then choose to add in a higher crypto transaction fee in order to prioritise their transaction in the mempool. 

Transaction fees for smart contracts are based on how much electricity will be needed to complete the task. Typically, transaction fees on smart contracts are much higher.

Generally, the terms transaction fee and network fee can be used interchangeably. They both refer to the transaction fee necessary by the network for the transaction to get processed.

Exchange fees refer to something else entirely. Exchange fees are fees charged by the exchange in order to conduct the service. Be sure to check before conducting a transaction on an exchange as you might be required to pay a transaction fee (or network fees) as well as exchange fees.

How to pay less for transaction fees

A transaction fee is imperative to your transaction getting executed so it cannot be avoided entirely, however, there are ways to reduce the amount you need to pay.

Transaction fees increase when the network is busy, so sending your transaction while the network is quieter is a great way to reduce the transaction fee. Typically the busier periods are during business hours in the United States. 

Look out for the Lightning Network for Bitcoin and layer-2 scaling solutions for Ethereum as these will provide a cost-effective solution to high transaction costs on those networks.

Which cryptocurrency has the lowest average transaction fee?

Let's take a look at some of the most popular cryptocurrencies and the average transaction fee associated with their platforms. 

XRP - $0.0002 per transaction

Developed by Ripple Labs, XRP is optimised for fast, affordable cross-border payments, with a focus on serving financial institutions and remittance providers. Thanks to its unique architecture, XRP has cemented its status as a key player in the payment processing space.

XRP's minimal costs and 4-second transaction times make it a preferred choice for users and institutions alike. 

Solana (SOL) - $0.00025 per transaction

Solana’s transaction fees cost just fractions of a cent ($0.00025), with complex transactions also coming in incredibly cheap. The network stands out for its lightning-fast transactions, typically wrapping up in about 2.5 seconds. Thanks to its scalable design, Solana can handle many transactions simultaneously, making it a hit for dapps and big blockchain projects.

This efficiency, coupled with its rapid speed, has made Solana a favourite among both developers and users, and a permanent feature in the top 10 biggest cryptocurrencies based on market cap (currently number 5).

Litecoin (LCH) - $0.0025 per transaction

Litecoin stands out as one of the cheapest crypto options out there, costing around $0.0025 per transfer. As an early pioneer in the space, Litecoin was designed with fast, affordable payments in mind, borrowing and refining Bitcoin's underlying technology. Litecoin's speedy 2.5-minute transaction times add to this appeal.

The minimal fees on Litecoin are a huge plus, with its efficiency and speed making Litecoin an attractive choice for those seeking a cost-effective crypto.

Bitcoin Cash (BCH) - $0.01 per transaction

Bitcoin Cash makes it onto the list with an attractive $0.01 average transaction fee. As a Bitcoin offshoot, BCH was engineered for faster, more affordable transfers via larger block sizes. 

The cost-effective fees on Bitcoin Cash have made BCH a viable option for those looking for a low-cost market entry and equally impressive low-cost transaction fees. 

Dogecoin (DOGE) - $0.04 per transaction

Dogecoin, born in 2013 as a playful take on crypto, has surprisingly become a significant player in the crypto space. Despite its lighthearted meme-inspired origins, Dogecoin's enthusiastic community and celebrity endorsements have propelled it into the mainstream. 

Its low $0.04 average transaction fees and fast 1-minute transaction times make it practical for frequent micro-transactions like tipping and donations, blending fun and function.
