## Gas Tokens

Every transaction on an EVM-compatible chain requires the native gas token to pay for network fees. Make sure your wallets (or your [Gas Station](/yativo-crypto/gas-station)) hold sufficient native token for the chain you're using.

| Chain               | Gas Token | Notes                                                               |
| ------------------- | --------- | ------------------------------------------------------------------- |
| Binance Smart Chain | BNB       | Low gas costs                                                       |
| XDC Network         | XDC       | Very low gas costs                                                  |
| Bitcoin             | BTC       | Fee is included in the transaction amount; set priority accordingly |
| Solana              | SOL       | Flat, very low fees per transaction                                 |
| Polygon             | POL       | Low gas costs, fast finality                                        |
| Base                | ETH       | L2 — gas costs are a fraction of Ethereum mainnet                   |
| Optimism            | OP        | L2 — significantly cheaper than Ethereum mainnet                    |
| Arbitrum            | ARB       | L2 — significantly cheaper than Ethereum mainnet                    |
| Tron                | TRX       | Low gas costs                                                       |
| Avalanche           | AVAX      | Low gas costs                                                       |
| Gnosis Chain (xDAI) | xDAI      | Very low gas costs                                                  |

<Tip>
  Use the [Gas Station](/yativo-crypto/gas-station) to pre-fund native token reserves. This lets the platform cover gas fees on behalf of your users so they only need to hold the token they want to transfer.

## Fetching Supported Assets via API

You can also retrieve the current list of supported chains and assets programmatically:

```bash theme={null}
# Get all supported assets
curl -X GET https://crypto-api.yativo.com/api/v1/assets/get-all-assets \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

# Get supported chains
curl -X GET https://crypto-api.yativo.com/api/v1/assets/get-chains \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```

Use these endpoints to dynamically populate chain and token selectors in your UI rather than hardcoding values.
