Clear Signing Under the Hood: A Technical Guide to ERC-7730

ERC-7730 is a JSON specification that enables wallets to display human-readable descriptions of raw transaction data before signing, addressing blind signing risks that contributed to losses at Bybit, WazirX, and Radiant Capital. The standard originated at Ledger and moved to Ethereum Foundation stewardship on May 12, 2026; it functions as a presentation layer without requiring protocol changes or contract redeployment. ERC-7730 descriptors consist of context constraints, metadata, and display rules, with companion standards ERC-8176 for auditor attestations and ERC-8213 for calldata digests.
