## Provider ID Quick Reference
Use the correct chain identifier for each data provider API:
| Chain | DexScreener ID | DefiLlama ID | Notes |
| --------- | -------------- | ------------ | --------------------------------------------- |
| Ethereum | `ethereum` | `ethereum` | |
| Base | `base` | `base` | |
| Arbitrum | `arbitrum` | `arbitrum` | |
| Optimism | `optimism` | `optimism` | |
| Polygon | `polygon` | `polygon` | |
| BNB Chain | `bsc` | `bsc` | Not `bnb` — both providers use `bsc` |
| Avalanche | `avalanche` | `avax` | IDs differ — DexScreener and DefiLlama differ |
| Celo | `celo` | `celo` | Limited DexScreener Uniswap data |
| Blast | `blast` | `blast` | Limited DexScreener Uniswap data |
| Zora | `zora` | n/a | Not on DefiLlama; DexScreener data limited |
| World | `worldchain` | n/a | Not on DefiLlama; DexScreener data limited |
| Unichain | `unichain` | `unichain` | Newer chain — pool data still growing |
**Key discrepancies:**
- **Avalanche**: DexScreener uses `avalanche`, DefiLlama uses `avax`
- **BNB Chain**: Both providers use `bsc`, not `bnb` (the URL parameter for Uniswap deep links is `bnb`)
- **Zora/World Chain**: Not indexed by DefiLlama — DexScreener only, with limited Uniswap pool data
## Token Address Lookup
When a user provides a token symbol, first check the common tokens list above. If not found:
1. Use web search: `"{symbol} token contract address {chain}"`
2. Verify the address on the chain's block explorer
3. Check if the token has liquidity on Uniswap
## Native Token Handling
For native tokens (ETH, MATIC, BNB, AVAX, CELO):
- Use `NATIVE` as the `inputCurrency` or `outputCurrency` parameter
- Do NOT use the wrapped token address for native tokens in swap URLs
**Examples:**
- Swap ETH → USDC: `inputCurrency=NATIVE`
- Swap WETH → USDC: `inputCurrency=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`
## RPC Rate Limits
Public RPCs have rate limits. For basic contract verification, public RPCs are sufficient. For production applications, consider using:
- Alchemy
- Infura
- QuickNode
- Or chain-specific premium RPCs
