# 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.

|
**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. `/tokens` or token tracker link).
|
|
- **Cronos:** Alternative official explorer: https://explorer.cronos.org (tokens section available).

## How to use
|
|
|
|
1. **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.
|
|
2. **Wemix (1111):** See [WEMIX_TOKEN_VERIFICATION.md](WEMIX_TOKEN_VERIFICATION.md) for current addresses and verification steps; primary list: https://scan.wemix.com/tokens.
|
|
3. **Tezos:** Use https://tzkt.io/contracts for FA1.2/FA2 (KT1) token and contract lookups; see [TEZOS_TOKEN_REGISTRY.md](../11-references/TEZOS_TOKEN_REGISTRY.md) for USDtz and related.
|
|
4. **Cross-check:** Where possible, cross-check with issuer docs (e.g. Tether, Circle) for official deployments on that chain.
