| Solana | `solana` | **Primary chain — full feature support** |
| Ethereum | `ethereum` | |
| BNB Smart Chain | `bsc` | |
| Base | `base` | |
| Arbitrum | `arbitrum` | |
| Optimism | `optimism` | |
| Polygon | `polygon` | |
| Avalanche | `avalanche` | |
| zkSync Era | `zksync` | |
| Sui | `sui` | |

| `GET /wallet/v2/current-net-worth` | Solana, Base |
| `GET /wallet/v2/net-worth` | Solana only |
| `GET /defi/v2/tokens/top_traders` | All chains — but PnL `sort_by` values (`total_pnl`, `unrealized_pnl`, `realized_pnl`, `volume_usd`) and `2d`–`90d` timeframes are **Solana-only** |
| `GET /defi/token_security` | All chains except Sui |
| `GET /trader/gainers-losers` | Solana only |
| `GET /defi/v3/token/meme/list` | Solana, BSC, Monad |

## Setting the Chain

```typescript
const client = BirdeyeClient.createWithConfig({ apiKey, chain: 'base' });
// or, to read apiKey from BIRDEYE_API_KEY env var:
// const client = BirdeyeClient.create('base');
```

> The chain is set in the **`x-chain` header**, never in the URL path.
> All chains share the same base URL: `https://public-api.birdeye.so`
