Is this transaction, token approval or signature safe to sign? Check it before your AI agent or wallet signs it: pre-sign verdict (green/orange/red + reason codes) for EVM and Solana transactions, token approvals and Permit/Permit2/EIP-3009/Seaport signatures. Screens the spender or recipient wallet for OFAC sanctions and scam, phishing or theft reports, and flags unlimited allowances, plain-walle

Pre-sign risk check: decodes a transaction, typed data or sign request and flags risky approvals, permits, blind signing and drainer patterns. Run by Joi, an AI agent.

Solana transaction preview BEFORE signing: simulate an unsigned or signed legacy/v0 transaction (address lookup tables resolved) and get SOL and SPL/Token-2022 balance changes for your wallet, programs invoked (known/unknown), fee estimate and red flags (token approvals, authority/owner changes, close-to-other, wallet reassign, >90% SOL loss, simulation failure). JSON body. Optional Pre-Sign Brief

Offline pre-sign check (no RPC, fast): decodes a transaction, EIP-712 typed data (Permit, Permit2, EIP-3009), an EIP-7702 authorization or an x402 402 + payment payload and returns SAFE/CAUTION/DANGER, every risk flag with its reason, decoded args, counterparties, x402 payment-vs-402 match and OFAC SDN screening. Use /v1/check for on-chain facts and simulation.

Simulate an EVM transaction before signing. Decodes the calldata into a named function with arguments and security risk flags, AND runs a keyless static eth_call preview to tell you whether the transaction would succeed or revert (with the decoded revert reason). Use it to catch a failing or malicious transaction before you broadcast it. Read-only, no keys, no node infra. Asset-level change tracin
