Metadata that wallets can use
Turn contract interactions into the context people need to make an informed decision, not a guess from hexadecimal calldata.
ERC-7730 metadata infrastructure
Know what a transaction does before you sign it.
KaiSign is open infrastructure for creating, reviewing, verifying, and distributing clear-signing metadata. Built for wallets, dapps, and the people who use them.
Network postureOpen-source, Ethereum-first
What moves through itHuman-readable transaction intent
What it replacesBlind signing and opaque calldata
Clear signing is public infrastructure.
Review without a gatekeeper
Metadata is designed to be inspectable and challengeable, so safety does not depend on a single vendor deciding what users are allowed to see.
Distribution that stays open
Build once and make descriptors available to the wallet ecosystem through decentralized, verifiable infrastructure.
