txKit - Arbitrum Open House London Buildathon

Verify before you sign

An autonomous agent prepares an Arbitrum transaction. You see a typed, decoded preview of exactly what it does before signing, and a minimum-viable policy gate enforces the rules on-chain.

txKit is the reference implementation of ERC-8265, a transaction-safety standard authored by Mike Diamond and submitted to Ethereum.
