Introducing SCREEN™ Blockchain Transaction Simulator
Blockchain technology has been revolutionizing the transition from web2 to web3, with smart contracts playing a pivotal role. These digital contracts, capable of automating transactions when predefined conditions are met, are the driving force behind countless decentralized applications (dApps) across Ethereum Virtual Machine (EVM) compatible blockchains.
Nevertheless, dealing with smart contract transactions can be challenging. In 2022, a startling $4 billion was swindled in cryptocurrency scams, with a significant portion attributed to malicious smart contracts, according to AnChain.AI’s research. This highlights the imperative need to understand and validate smart contract transactions before they are executed. AnChain.AI’s SCREEN™ Transaction Simulator has been engineered to address this challenge.
Introducing SCREENTM Blockchain Transaction Simulator
Our Transaction Simulator is a robust feature that offers a glimpse into the potential outcomes of Ethereum transactions by simulating them without any real-world implications. Think of it as a flight simulator for blockchain transactions, letting you experiment with various conditions and scenarios, boosting your confidence and comprehension of smart contract transactions before they are executed on the blockchain.
Let’s delve into the simulator’s capabilities.
The Power of the Transaction Simulator
Test Smart Contract Performance:
The simulator provides a secure environment for you to test the functionality and performance of your smart contracts before deployment. By simulating transactions involving smart contracts, you can detect potential issues, vulnerabilities, or inefficiencies, and make necessary modifications to boost the contract’s overall performance.
Identify and Address Unexpected Results:
If any unexpected results arise during the simulation process, such as a logic error in the smart contract or incorrect parameter inputs, the simulator empowers you to identify and resolve these issues before they impact your actual transaction.
Simulating transactions can be complex and scaling this process further increases its complexity. Conventional methods have their limitations and alternative approaches can be costly, confusing, or lacking in functionality. Our Transaction Simulator sidesteps these hurdles, offering an accessible, intuitive, and effective solution for users to navigate the world of Ethereum transactions with ease and confidence.
The SCREEN Transaction Simulator in Action
Let’s simulate a mainnet transaction: 0xde46a6bb1fc7834dde4d01428c88f84d65a607f4dc11b7f3dd710e86b7d226a8, which unexpectedly swapped approximately 2 million $crv tokens (valued at $1.8 million) from 0x8…b66 on Kyberswap for just ~0.051 USDT (a fraction of a US dollar).
We start by providing the necessary inputs for the simulation.
Once we’ve filled out the required information, we simply click “Run Simulation”. After a brief wati, we’re then directed to the “Results” page, which shows an overview of the simulated transaction result.
In this sample the successfully simulated the transaction results in the swapping of ~2 million $CRV tokens for ~0.05 USDT. As evident from the balance changes post-transaction, the 0x8…b66 lost 2m CRV but only gained 0.5 USDT.
