TetraHelix Guard is a local-first transaction-intent firewall that protects crypto-wallet users by decoding unsigned transactions, comparing their actual effects with user intent, and warning about suspicious requests before signing—without accessing private keys or taking custody.
TetraHelix Guard is a local-first, non-custodial transaction-intent firewall for crypto wallets. It decodes unsigned transactions, compares their actual effects with the user’s stated intent, and warns about suspicious approvals, transfers, swaps, and contract interactions before signing—without accessing private keys or taking custody.
For Arbitrum Open House, we are building an Arbitrum integration and an onchain policy registry on Arbitrum Sepolia. The registry will store versioned hashes of user security policies without exposing private transaction data, while the browser extension performs local transaction decoding and intent checks.
