The Pectra merge is finally here and everyone is talking about one-click batch execute. At Biconomy, we went a step further and cooked a framework making EIP-7702 the engine enabling seamless multichain interop, class leading DevEx and one-click, gasless UX for users. Read 👇

EIP-7702 is a new era for onchain UX. By enabling any EOA to become a Smart Account - it's bringing an unprecedented level of account programmability. What Ethereum was to Bitcoin, EIP-7702 is to EOAs - instead of a protocol defined account, you get a fully programmable one. DeFi Demo -

At Biconomy - we've taken full advantage of EIP-7702! Instead of just providing single-chain batch execute or gasless transactions - our Modular Execution Environment (MEE) brings superpowers to your EIP-7702 enabled EOA - making it a one-click, gasless, multichain powerhouse! Full LOOM Demo -

With MEE, users can execute multiple asynchronous transactions, across multiple chains - with a single user signature. By leveraging the built-in Composability Stack - developers can use the output of one function call as the input of the next - without writing smart contracts.

Asynchronous execution guarantees that your flows can include calls to bridges, wait for oracle updates, schedule execution in the future and create repeating function calls (like DCA or TWAP flows).

Composable execution means you never have to guess the output amount of a DEX swap or a bridge to input into the next call. Simply set the input parameter as a template and MEE will dynamically inject the exact output value - during runtime.

The entire setup is trustless - our nodes never take custody over user funds! All execution, including composability - is enforced fully onchain by MEE-specific validator modules on our battle-tested, thoroughly audited, ERC-7579 compliant - Nexus Smart Account implementation.

An example flow which bridges USDC from Arbitrum to Base, waits for the funds to arrive to Base, swaps USDC for WETH and then supplies WETH to a Morpho - is now just a single signature for the user - with MEE taking care of orchestrating everything and abstracting away gas.

The user started with the wrong asset, on the wrong chain and didn't have gas on source or destination and still - they successfully supplied to their desired vault in seconds! Biconomy MEE sets the gold standard in onchain UX - no matter how many chains you're operating on!

What also sets MEE apart is the developer experience! Instead of manually setting dependencies between transactions - the MEE intelligently auto-orchestrates the entire execution by simulating dependencies of each function call and creating the proper ordering of operations.

Give Biconomy a try and build the UX of the future, seamlessly interop Ethereum and all its rollups and enjoy the best onchain DevEx you've ever had. All of our tools are 100% open-source and vendor agnostic - meaning it's you who chooses which bridge, chain or wallet to use.

Our flagship SDK - AbstractJS - is your interface to MEE. It's built on top of Viem and can easily be plugged into any standard EVM project! It works with external wallets (MetaMask, Rabby, Trust, ...), embedded wallets (Privy, Dynamic, ...) and backend signers (e.g. Turnkey).
