FabTally Safe

Crypto safety & "what am I signing" verification

Read-only, per-call checks that stop honeypots, rug pulls and wallet drains — for humans and AI agents. Multi-chain token honeypot/rug scoring, EIP-712 / Permit2 / Seaport signature decoding, approval-risk scans, and keyless pre-sign simulation. Pay per call over x402 (USDC on Base) or a prepaid credit key.

Endpoints & pricing

POST /v1/token-safety $0.02

Multi-chain honeypot/rug check. Aggregates GoPlus + honeypot.is into a normalized 0-100 risk score with explainable reasons: honeypot / can't-sell, buy/sell tax, mint/blacklist/pausable/ownership privileges, top-holder concentration, LP-lock, verified/bytecode.

POST /v1/decode-signature $0.01

Decode an off-chain EIP-712 signature (Permit / Permit2 / Seaport / generic) into plain English + risk flags: unlimited approval, unknown/malicious spender, never-expiring or expired deadlines, zero-consideration NFT-drain orders.

POST /v1/approvals $0.01

Wallet approval-risk scan ranked by exposure. Flags unlimited amounts, unverified/malicious spenders and address-poisoning "revoke bait" — and returns the exact revoke calldata you execute yourself. We never execute.

POST /v1/simulate $0.02

Keyless pre-sign transaction analysis: public-RPC eth_call revert check + static calldata decode predicting approval/transfer deltas + risk flags. Honest keyless limitation stated in the response (no full fork trace).

Every paid endpoint has a /free teaser (used by this demo). No payment → an x402 v2 402 challenge (USDC on Base, eip155:8453); pay and retry, or send a prepaid X-FabTally-Key credit header. Bad input → 400, never charged. Discovery: /agent/overview · /openapi.json · /.well-known/x402. MCP: https://safe.fabtally.com/mcp.

Read-only & non-custodial. FabTally Safe never holds, moves, signs for, or broadcasts funds or transactions, and stores no request data. Every response is descriptive on-chain/offline fact from public sources (GoPlus, honeypot.is, public RPC) — not financial, investment, or safety advice, and never a recommendation to buy, sell, hold, approve, or sign.
