Explorer Token Lists — Canonical Mapping Reference
Last Updated: 2026-02-16
Purpose: Single reference for block explorer tokens/contracts list URLs used to verify canonical token addresses for multichain mapping. Use these when updating config/token-mapping-multichain.json or validating WETH/USDT/USDC (and other tokens) per chain.
EVM chains (token list or token tracker)
| Chain ID | Network | Explorer | Tokens / contracts list URL |
|---|---|---|---|
| 1 | Ethereum Mainnet | Etherscan | https://etherscan.io/tokens |
| 10 | Optimism | OP Mainnet Etherscan | https://optimistic.etherscan.io/tokens |
| 25 | Cronos | CronosScan | https://cronoscan.com/tokens |
| 56 | BSC (BNB Chain) | BscScan | https://bscscan.com/tokens |
| 100 | Gnosis Chain | Blockscout | https://gnosis.blockscout.com/tokens |
| 100 | Gnosis Chain | Gnosisscan | https://gnosisscan.io/tokens |
| 137 | Polygon | PolygonScan | https://polygonscan.com/tokens |
| 138 | SMOM-DBIS-138 | Blockscout (d-bis) | https://explorer.d-bis.org/tokens |
| 8453 | Base | BaseScan | https://basescan.org/tokens |
| 42161 | Arbitrum One | Arbiscan | https://arbiscan.io/tokens |
| 42220 | Celo | CeloScan | https://celoscan.io/tokens |
| 43114 | Avalanche C-Chain | Snowtrace | https://snowtrace.io/tokens |
| 651940 | ALL Mainnet (Alltra) | Alltra | https://alltra.global (explorer; check for /tokens or token section) |
| 1111 | Wemix | WemixScan | https://scan.wemix.com/tokens |
Notes:
- Gnosis: Two explorers; Blockscout and Gnosisscan both provide token lists.
- Chain 138: Our Blockscout instance at explorer.d-bis.org; standard Blockscout path
/tokens. - ALL Mainnet (651940): Explorer at alltra.global; confirm tokens list path on site (e.g.
/tokensor token tracker link). - Cronos: Alternative official explorer: https://explorer.cronos.org (tokens section available).
Non-EVM / other
| Chain / network | Explorer | Contracts / tokens list URL |
|---|---|---|
| Tezos (L1) | TzKT | https://tzkt.io/contracts |
| Etherlink (42793) | Blockscout | https://explorer.etherlink.com/tokens |
How to use
- Verify canonical addresses: When adding or updating a chain in
config/token-mapping-multichain.json, open the tokens/contracts list URL for that chain and confirm WETH, USDT, USDC (and any other tokens) contract addresses. - Wemix (1111): See WEMIX_TOKEN_VERIFICATION.md for current addresses and verification steps; primary list: https://scan.wemix.com/tokens.
- Tezos: Use https://tzkt.io/contracts for FA1.2/FA2 (KT1) token and contract lookups; see TEZOS_TOKEN_REGISTRY.md for USDtz and related.
- Cross-check: Where possible, cross-check with issuer docs (e.g. Tether, Circle) for official deployments on that chain.
