{"slug":"txguard-93856b5b","name":"TxGuard","summary":"Explain and preflight an unsigned Base transaction, EIP-712 typed data, or an EIP-3009 x402 payment authorization before you sign it. Decodes intent against verified ABIs, resolves proxies, classifies approvals, and checks a payment authorization against the quote it claims to pay: recipient, amount, asset, chain, freshness, and nonce replay. Returns unknown rather than guessing when a selector is ambiguous. Not a guarantee that a transaction is safe or profitable.","status":"live","indexable":true,"listed_since":"2026-10-30T18:38:36.859147Z","sources":[{"source":"x402_bazaar","external_id":"https://txguard.schemasure.com/v1/tx/preflight","owner_address":"0x9876af0f6d8ed5155cd02d1ca56d128601612690","seen_at":"2026-10-31T18:51:46.297648Z","removed_at":null}],"endpoints":[{"url":"https://txguard.schemasure.com/v1/tx/preflight","host":"txguard.schemasure.com","protocol":"x402","state":"live","last_probe_at":"2026-10-31T23:45:01.852917Z","last_ok_at":"2026-10-31T23:45:01.852917Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"txguard-schemasure-com-6eb5fd22","name":"txguard.schemasure.com"}],"payment_options":[{"endpoint_url":"https://txguard.schemasure.com/v1/tx/preflight","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"20000","pay_to":"0x9876af0f6d8ed5155cd02d1ca56d128601612690","observed_at":"2026-10-31T23:45:01.852917Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":6,"paid_calls_30d":17,"last_paid_at":"2026-10-31T07:39:33.547Z","reported_at":"2026-10-31T18:51:46.297648Z"},"assessment":{"method":"2026.10.2","checks":[{"id":"answers","state":"pass","reason":"Answered a check within the last hour."},{"id":"owner","state":"fail","reason":"No one has proven control of its domain or of the wallet it is paid at."},{"id":"track_record","state":"fail","reason":"Listed for 1 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"6 different wallets paid it in 30 days, as the x402 Bazaar reports (not yet counted by addrbook); 10 are needed."},{"id":"clean_scan","state":"not_applicable","reason":"Not an MCP server."}],"passed":1,"applicable":4,"contradicted":false,"computed_at":"2026-11-01T00:26:26.414052Z"},"identity":{"endpoint_domains":["schemasure.com"],"proven_domains":[],"proven_wallets":[],"namesakes":[],"namesake_count":0,"identity_checks":[],"wallet_attestations":[],"human_backings":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
