X Layer Token List

A standards-compliant Uniswap Token List for the X Layer network, used by wallets (e.g., MetaMask) and dApps to discover tokens and logos.

• Token list file: https://raw.githubusercontent.com/okx/xlayer-tokenlist/main/xlayer.tokenlist.json
• Schema: Uniswap Token List (validated)

Chains

• 196 — X Layer Mainnet (chainId: 196)

Chain metadata can also be found in ethereum-lists/chains.

Current Release — v1.0.0

• Scope: Initial release of core token list for X Layer Mainnet
• Tokens (196): WOKB, WETH, USD₮0, USDC
  • WOKB (Wrapped OKB) — Primary wrapped token for X Layer
  • WETH (Wrapped Ether) — Ethereum wrapped token
  • USD₮0 — Stablecoin
  • USDC (USD Coin) — USD stablecoin
• Logos:
  • All logos are referenced from OKLink to ensure high availability and fast loading

Usage

Wallet/dApp Integration

Wallets and dApps that support Uniswap Token Lists can directly import this list file.

Programmatic Validation

# Schema validation
npx ajv-cli validate -s token-lists/src/tokenlist.schema.json -d xlayer.tokenlist.json

# Checksum validation
node -e "const {toChecksumAddress}=require('web3-utils');const l=require('./xlayer.tokenlist.json');for(const t of l.tokens){if(t.address!==toChecksumAddress(t.address))throw new Error('Bad checksum '+t.address)}console.log('OK')"

Versioning & Validation

Semantic Versioning

Versioning follows Uniswap's SemVer guidance:

• Major: Remove tokens or change token address/chainId (for previously published tokens)
• Minor: Add tokens
• Patch: Metadata updates (name, symbol, logo, decimals)

Validation Coverage

• Uniswap JSON schema
• EIP-55 address checksums
• Duplicate token detection
• Logo link availability verification (HTTP 200)
