For methods that submit transactions, it's possible to override default transaction variables by passing an ethers overrides object:

The overrides object for write methods may include any of:

  • overrides.gasPrice - the price to pay per gas
  • overrides.gasLimit - the limit on the amount of gas to allow the transaction to consume; any unused gas is returned at the gasPrice
  • overrides.value - the amount of ether (in wei) to forward with the call
  • overrides.nonce - the nonce to use for the Signer

To send an EIP-1559 transaction, specify maxPriorityFeePerGas and maxFeePerGas instead of gasPrice.

For example, to accept an offer with 150 gwei priority fee and 500 gwei max fee, call the acceptOffer method as follows:

await acceptOffer({
},
{
  maxPriorityFeePerGas: ethers.utils.parseUnits('150', 'gwei'), // 150 gwei
  maxFeePerGas: ethers.utils.parseUnits('500', 'gwei') // 500 gwei
})
