# AA31: Insufficient Paymaster Funds

<Note>
  The paymaster contract address is specified in the first 20 bytes of `paymasterAndData`.
</Note>

The specified paymaster contract lacks sufficient funds in the EntryPoint contract to cover the required prefund for your user operation.

## Resolution Strategies

1. Paymaster Address Verification:
   * Double-check the accuracy of the `paymasterAndData` field
   * Ensure the first 20 bytes correctly represent your intended paymaster contract address

2. For Self-Managed Paymasters:
   * Increase the deposit in the EntryPoint contract
   * Use the paymaster contract's `deposit()` function to add funds

3. For Third-Party Paymaster Services:
   * Reach out to the respective team, if you are using JiffyLabs, [reach out to us](https://t.me/JiffyScan)
