Gas Policy

The gas policy specifies how much gas the signer can use in total, across all UserOps it sends. It can also enforce that the UserOps must use paymasters, or use a specific paymaster.

API

import { toGasPolicy } from "@zerodev/permissions/policies"
 
// Set a total amount
const gasPolicy = toGasPolicy({
  allowed: parseEther('0.1'),
})
 
// Or enforce that a paymaster must be used
const gasPolicy = toGasPolicy({
  enforcePaymaster: true,
})
 
// Or enforce that a specific paymaster is used
const gasPolicy = toGasPolicy({
  allowedPaymaster: "PAYMASTER_ADDRESS",
})
 
const validator = toPermissionValidator(publicClient, {
  entryPoint,
  kernelVersion,
  signer: someSigner,
  policies: [
    gasPolicy,
    // ...other policies
  ],
})

toGasPolicy takes one or more of the following arguments:

• allowed: an amount, in wei, of the ETH (or whatever native token) that the signer can spend on gas, in total across all UserOps it sends.
• enforcePaymaster: a boolean value. If set to true, enforce that a paymaster must be used.
• allowedPaymaster: a paymaster address. If set, enforce that the specific paymaster is used.
