1/7 ERC-7730 gives wallets, dapps, hardware wallets, and tools a shared format for clear-signing metadata. That matters. But the format alone does not solve the full problem. Clear-signing metadata can be verifiable, but the verification path still has points of failure.

2/7 Today, clear-signing metadata verification can still depend on centralized actors: wallet vendors hardware wallet vendors curated metadata sources closed review processes controlled distribution paths That means users may still depend on one party to decide what metadata is accepted, rejected, updated, or removed.

3/7 KaiSign is built to reduce those points of failure. It is an on-chain registry for ERC-7730 metadata. Metadata is tied to contract bytecode, attested on-chain, bonded, challengeable, and finalized. The goal is not “verification from nothing.” The goal is removing centralized chokepoints from metadata verification.

4/7 For now, KaiSign is selecting early attesters before opening attestation more broadly. This is intentional. Bad metadata can be as dangerous as blind signing. A fake clear-signing explanation can make a malicious transaction look safe. Attesters help review, submit, challenge, and improve metadata quality.

5/7 The registry flow is accountability-based: prepare ERC-7730 metadata → commit the submission → approve the bond token → reveal the metadata hash → Oracle resolution → finalize approved metadata on-chain Only finalized metadata becomes discoverable as an attested KaiSign entry.

6/7 The goal is not just readable transactions. The goal is fewer centralized failure points in how clear-signing metadata is submitted, verified, challenged, and trusted. We are selecting early attesters now. DM us or drop a comment.

7/7 Repo: github.com/Kai-Sign/MCP/blob… Use the repo to run the minimum CLI: test ERC-7730 metadata locally, clear-sign calldata, and inspect readable transaction intent before submitting. Docs: kaisign.gitbook.io/kaisign/d… Use the docs to submit metadata on Sepolia: commit → approve bond token → reveal → oracle submission → finalize.
