Nethermind's @svlachakis_ co-authored Frame Transactions (EIP-8141) for the Hegotá upgrade, planned for 2027. What Frame Transactions change: An app can pay a user’s fee and get paid back in a stablecoin like USDC. Smart wallets can let users sign with a phone passkey or change their key without moving funds. Wallets do this today with extra offchain services. With Frame Transactions, Ethereum supports this directly. We’ve built them into the Nethermind Client. See how they work in the video below.
