3/15 🧵 How ERC-7730 Works - Developers submit metadata files describing smart contract functions. - Ledger signs and verifies them to ensure integrity. Wallets fetch this data so users see exactly what they are signing

4/15🧵Security First - Attackers are getting more sophisticated. Malware can modify transactions before signing - ERC-7730 ensures users see what they are about to sign. Ledger is making this a public good that any wallet can integrate

7/15🧵 EIP-7702 vs. ERC-4337 - 7702 converts EOAs into smart accounts, but the original key always retains control - 4337 fully replaces EOAs with smart accounts, removing the single point of failure. If security is a priority, 4337 is preferred
