AA21 didn’t pay prefund
What it means
The bundler provider reported that the paymaster did not provide sufficient funds to sponsor this user operation.
How to fix it
No paymaster
If not using a paymaster and funding the transaction, ensure the smart account has sufficient gas funds.
thirdweb paymaster
If using the thirdweb paymaster, your sponsored transactions may have exceeded a sponsorship rule. Increase the limits for your API key from the thirdweb dashboard. For more details see Sponsorship Rules.
Other paymasters
If using Stackup, Alchemy, Pimlico, Biconomy, or other paymasters, ensure your paymaster and data values are set correctly. Consult the provider’s documentation for more details.
