Delegatecall

delegatecall is a powerful EVM opcode that allows the calling contract to execute code in another contract, while keeping the storage context. You can read more about delegatecall here.

API

To send a UserOp that uses delegatecall, simply specify the callType of the UserOp:

const userOpHash = await kernelClient.sendUserOperation({
  userOperation: {
    callData: await kernelClient.account.encodeCallData({
      to: targetAdress,
      data: callData,
      value: 0n,
      callType: "delegatecall",
    }),
  },
})
