Gas Estimation and Overrides

The SDK allows you to:

  • View the current gas cost in gwei
  • Estimate the gas cost of a transaction at the current point in time
  • Override parts of a transaction (e.g. gas limit, gas price, nonce, from, value, etc...)

Current Gas Price​

const gasCostInGwei = await contract.estimator.currentGasPriceInGwei();

Estimate Transaction Gas Cost​

const costOfClaim = await nftDrop?.estimator.gasCostOf("claim", [
  "0x...", // receiver
  1, // quantity
  "0x...", // currency
  1, // price per token
  [], // proofs
  1, // proof max quantity per transaction
]);
