# Extra gas limits

Allbridge has limits for extra gas amount. To check the max value of extra gas you have to use the [getExtraGasMaxLimits](https://bridge-core-sdk.web.app/classes/AllbridgeCoreSdk.html#getExtraGasMaxLimits) method

```typescript
  const extraGasMax = await sdk.getExtraGasMaxLimits(sourceToken, destToken);
  console.log("extraGas Limits =", JSON.stringify(extraGasMax, null, 2));
```
