Free Mints

Publishers can choose to offer free mints where the publisher pays the gas costs by setting up a relayer service and then passing those options into their thirdweb SDK connection. By doing so all write transactions to the blockchain will be forwarded to that service for payment of the gas.

gasless: {
// By specifying a gasless configuration - all transactions will get forwarded to enable gasless transactions
openzeppelin: {
relayerUrl, // your OZ Defender relayer URL
relayerForwarderAddress, // the OZ defender relayer address (defaults to the standard one)
biconomy: {
apiId, // your Biconomy API Id
apiKey, // your Biconomy API Key
deadlineSeconds, // your Biconomy timeout preference
