Ambire and Trezor add EIP-7730 clear signing support

September 9, 2026

EIP-7730 clear signing is now supported in both Ambire and Trezor, letting users see human-readable, understandable transactions before approving them. The feature delivers the clear signing (ERC-7730) capability Ambire flagged in its H1 2026 roadmap, helping users "know what you sign" instead of blind-signing opaque payloads.
