intents-cli

A CLI tool for signing and executing user operations.

Building the Application

To build the application, run:

make build

Configuration

Before running this, your .env file should be set up with the necessary configurations like ETH_NODE_URL, SIGNER_PRIVATE_KEY, etc. Checkout .env.example for the reference.

Running the Application

Using JSON Input String

To run the application with a JSON input string, use:

intents-cli --u 'USER_OP_JSON'

Note the userOp nonce value is automatically generated by the CLI.

Using JSON File

Alternatively, you can use a JSON file as input:

intents-cli [command] --u ./sample.json

Available Commands

• sign: Sign a userOp.
• send: Submit a userOp to the node's EVM Entrypoint handleOps.
• sign-send : Sign and send a userOp.

Available Flags

• --u: User operation JSON as string or path to a JSON file.

Example

1 - Sign a blank userOp without initcode or calldata values:

intents-cli sign --u '{
        "sender":"0x1af5Dc71CE5F2e3aE90bf2b3ECD0a3498f981ab3",
        "nonce":"0x0",
        "initCode":"0x",
        "callData":"",
        "callGasLimit":"0xc3500",
        "verificationGasLimit":"0x996a0",
        "preVerificationGas":"0x99000",
        "maxFeePerGas":"0x0",
        "maxPriorityFeePerGas":"0x0",
        "paymasterAndData":"0x",
        "signature":"0x"
}'

2 - Sign a userOp with initcode and calldata values:

Note here the EIP-4337 initcode spec for creating a new account: initcode-spec.md

intents-cli sign --u '{
        "sender":"0x1af5Dc71CE5F2e3aE90bf2b3ECD0a3498f981ab3",
        "nonce":"0x0",
        "initCode":"0x42E60c23aCe33c23e0945a07f6e2c1E53843a1d55fbfb9cf000000000000000000000000fd4ec985482e1ed2b651293025EDaD889FaC3947",
        "callData":"0x5fbfb9cf000000000000000000000000fd4ec985482e1ed2b651293025EDaD889FaC394700",
        "callGasLimit":"0xc3500",
        "verificationGasLimit":"0x996a0",
        "preVerificationGas":"0x99000",
        "maxFeePerGas":"0x0",
        "maxPriorityFeePerGas":"0x0",
        "paymasterAndData":"0x",
        "signature":"0x"
}'
