What is one-wallet?
one-wallet is a robust command-line interface designed to bridge the gap between terminal environments and the Ethereum blockchain. As a key component of Openclaw Skills, it provides a high-level abstraction for managing private keys, querying balances, and interacting with smart contracts. It is built for developers who need to script blockchain actions or empower AI agents with transactional capabilities.
The tool excels in automation-heavy environments, offering machine-readable JSON outputs and comprehensive support for EIP-191 and EIP-712 signing. Whether you are deploying contracts or managing assets, this skill ensures that EVM operations are fast, secure, and easily integrated into larger technical stacks.
one-wallet Use Cases
- Managing multiple agent wallets through a single CLI interface.
- Automating ETH or ERC20 token transfers in scripting environments.
- Inspecting smart contract states and transaction receipts on the fly.
- Securely signing messages and typed data for decentralized application authentication.
How one-wallet Works
- Set the network provider using presets like mainnet or a custom RPC URL.
- Initialize a wallet by creating a new one or importing an existing private key.
- Perform on-chain actions such as sending funds or calling contract methods using clear CLI commands.
- Utilize the --json flag to pipe structured data into other tools or AI processing pipelines.
one-wallet Setup
Install the package globally via your preferred package manager:
npm install -g one-wallet
Configure your RPC provider to begin:
one-wallet provider set mainnet
Verify the installation:
one-wallet --help
