By utilizing , Mute allows for gas to be paid with other tokens instead of ETH.
Instead of paying a transaction fee of $0.40 with ETH, the user can opt in to use any of the supported tokens below. The conversion price is based on the token/ETH LP pool on the Mute Switch.
This is a free to use service.
Integration
You can easily integrate the Mute Paymaster into your dApp -
const PAYMASTER_ADDRESS = '0x4ae2Ba9A5C653038C6d2F5D9F80B28011A454597'
...
// approve the token for spending via the paymaster
...
const greeting = "a new greeting";
const tx = await greeter.populateTransaction.setGreeting(greeting);
const gasPrice = await sender.provider.getGasPrice();
const gasLimit = await greeter.estimateGas.setGreeting(greeting);
const paymasterParams = utils.getPaymasterParams(testnetPaymaster, {
type: "ApprovalBased",
TOKEN_ADDRESS,
minimalAllowance: ethers.BigNumber.from(1),,
innerInput: new Uint8Array(),
});
const sentTx = await sender.sendTransaction({
...tx,
maxFeePerGas: gasPrice,
maxPriorityFeePerGas: BigNumber.from(0),
gasLimit,
customData: {
gasPerPubdata: utils.DEFAULT_GAS_PER_PUBDATA_LIMIT,
paymasterParams,
},
});
