{"slug":"proxy-implementation-arbitrum-44e99d3a","name":"Proxy implementation, Arbitrum","summary":"Proxy implementation, Arbitrum. Find the implementation behind a proxy contract on Arbitrum One: reads the EIP-1967 implementation, beacon and admin slots, EIP-1822 (UUPS), the older OpenZeppelin layout and EIP-1167 minimal-proxy bytecode, and names the kind found. Use before trusting or decoding a contract whose code can be swapped by its admin; for a fuller risk verdict use contract_risk. A malformed address is 400; an address without code is 404, both uncharged.","status":"live","indexable":true,"listed_since":"2026-10-25T17:52:23.517383Z","sources":[{"source":"x402_bazaar","external_id":"https://agent-data-tools.revmesh2074.workers.dev/arb/proxy","owner_address":"0x2074c40346ae2a90e0e4a391bcee6f16bf5277f5","seen_at":"2026-10-26T06:00:45.307955Z","removed_at":null}],"endpoints":[{"url":"https://agent-data-tools.revmesh2074.workers.dev/arb/proxy","host":"agent-data-tools.revmesh2074.workers.dev","protocol":"x402","state":"live","last_probe_at":"2026-10-26T06:18:48.751477Z","last_ok_at":"2026-10-26T06:18:48.751477Z","tools_count":null,"tools_changed_at":null,"uptime_24h":1.0,"uptime_30d":1.0}],"also_listed_as":[{"slug":"agent-data-tools-revmesh2074-workers-dev-090312c0","name":"agent-data-tools.revmesh2074.workers.dev"}],"payment_options":[{"endpoint_url":"https://agent-data-tools.revmesh2074.workers.dev/arb/proxy","network":"eip155:8453","scheme":"exact","rail":"exact","asset":"0x833589fcd6edb6e08f4c7c32d4f71b54bda02913","coin":"USDC","asset_label":"USD Coin","amount":"10000","pay_to":"0x2074c40346ae2a90e0e4a391bcee6f16bf5277f5","observed_at":"2026-10-26T06:18:48.751477Z"},{"endpoint_url":"https://agent-data-tools.revmesh2074.workers.dev/arb/proxy","network":"eip155:137","scheme":"exact","rail":"exact","asset":"0x3c499c542cef5e3811e1192ce70d8cc03d5c3359","coin":"USDC","asset_label":"USD Coin","amount":"10000","pay_to":"0x2074c40346ae2a90e0e4a391bcee6f16bf5277f5","observed_at":"2026-10-26T06:18:48.751477Z"}],"usage":{"source":"x402_bazaar","unique_payers_30d":2,"paid_calls_30d":3,"last_paid_at":"2026-10-25T12:06:00.085Z","reported_at":"2026-10-26T06:00:45.307955Z"},"notice":"Not affiliated with addrbook — claim or request removal."}
