what's Magnee?

Magnee is a browser extension that intercepts payable Ethereum transactions on any dApp, enabling users to pay from a different chain or token seamlessly. It eliminates the need for manual bridging or swapping by leveraging li.fi for bridge quotes and EIP-7702 delegate contracts (MagneeDelegateAccount) for cross-chain execution, with EIP-712 signed authorizations for security.[[1]](https://ethglobal.com/showcase/magnee-dude7)[[2]](https://www.magn.ee/) It supports major chains including Ethereum, Optimism, Base, and Arbitrum, plus same-chain batching via wallet_sendCalls (ERC-5792). User settings are stored in ENS text records, and it includes a transaction explorer app and MetaMask patch for compatibility.[[1]](https://ethglobal.com/showcase/magnee-dude7)
