{"slug":"base-transfer-risk-11dc7234","name":"Base Transfer Risk","summary":"Check a Base ERC-20 for a honeypot-style transfer cost before a swap or send. Input: one token address. Output: allow, warn, or block. Block: not a contract or not an ERC-20. Warn: bytecode contains taxFee, liquidityFee, sellFee, buyFee, transferFee, isBlacklisted, or maxTxAmount. USDC warns because it contains isBlacklisted(address). A selector does not prove the fee, blacklist, or cap runs on every transfer, and this check does not simulate one.","status":"live","indexable":true,"listed_since":"2026-10-25T17:51:50.767216Z","sources":[{"source":"x402_bazaar","external_id":"https://base-token-check.fly.dev/v1/transfer-check","owner_address":"0x540c2aa2526c9c8c2fb4632f0fed668c36424cd5","seen_at":"2026-10-26T19:24:46.324007Z","removed_at":null}],"endpoints":[{"url":"https://base-token-check.fly.dev/v1/transfer-check","host":"base-token-check.fly.dev","protocol":"x402","state":"live","last_probe_at":"2026-10-26T04:55:53.522503Z","last_ok_at":"2026-10-26T04:55:53.522503Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"base-token-check-fly-dev-bef96e08","name":"base-token-check.fly.dev"}],"payment_options":[],"usage":{"source":"x402_bazaar","unique_payers_30d":3,"paid_calls_30d":4,"last_paid_at":"2026-10-10T17:41:56.782Z","reported_at":"2026-10-26T19:24:46.324007Z"},"assessment":{"method":"2026.10.1","checks":[{"id":"answers","state":"pass","reason":"Answered a check 9 hours ago."},{"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 0 days; 30 are needed."},{"id":"real_customers","state":"fail","reason":"3 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":"2026-10-26T14:48:24.132077Z"},"identity":{"endpoint_domains":["base-token-check.fly.dev"],"proven_domains":[],"proven_wallets":[],"namesakes":[],"namesake_count":0,"identity_checks":[],"wallet_attestations":[]},"replies":[],"customers":null,"scan":null,"notice":"Not affiliated with addrbook — claim or request removal."}
