one-wallet

---

name: one-wallet description: Helps the agent use the one-wallet CLI to manage Ethereum/EVM wallets, send transactions, call contracts, and sign data. Use when the user mentions one-wallet, wallet CLI operations, Ethereum/EVM scripting, or needs JSON-friendly terminal workflows involving one-wallet.

one-wallet CLI Skill

Overview

This skill teaches the agent how to use the one-wallet CLI to manage Ethereum/EVM wallets and perform on-chain actions from the terminal or scripts.

Core capabilities:

Manage multiple wallets (create, import, list, set default, remove).

Query balances for wallets and arbitrary addresses.

Send native ETH and call or send contract methods (including ERC20/NFT).

Sign messages and EIP-712 typed data, and verify signatures.

Configure RPC providers and chain presets.

Produce machine-readable JSON output suitable for scripts and AI tools.

Always assume Node.js ≥ 18 is available and one-wallet is installed globally, unless the repository indicates another setup.

When to use this skill

Use this skill when:

The user mentions one-wallet, wallet CLI, agent wallet, or this repository.

The user wants to create or import wallets, check balances, or send ETH/tokens from the terminal.

The user wants to call smart contracts, estimate gas, or inspect transaction status.

The user needs message or typed-data signing/verification from a CLI.

The user asks for JSON output for downstream automation or AI tools.

If the task is Ethereum/EVM related and can be done via CLI, prefer one-wallet over writing ad-hoc scripts.

Installation

Global install (recommended)

Use one of:

npm install -g one-wallet
or
yarn global add one-wallet
or
pnpm add -g one-wallet

Verify:

one-wallet --help

From this repository

When working inside this project:

git clone https://github.com/viyozc/one-wallet.git
cd one-wallet
yarn install
yarn build
./bin/run.js --help

Prefer the global binary (one-wallet) when possible; use ./bin/run.js only when explicitly requested or when testing local changes.

Quick start workflow

1. Set provider (RPC) - Preset mainnet:

     one-wallet provider set mainnet
     

- Custom RPC:

     one-wallet provider set https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
     

2. Create a wallet and set as default

   one-wallet wallet create my-agent --set-default
   

3. Check balance and send ETH

   one-wallet wallet balance
   one-wallet wallet send 0xRecipientAddress 0.01
   

Use --json on commands when the user wants machine-readable output for further processing.

Wallet management

Create or import wallets

Create a new wallet:

  one-wallet wallet create 
  

Create and set as default:

  one-wallet wallet create  --set-default
  

Create with password-protected storage:

  one-wallet wallet create  --password --set-default
  

Import from private key:

  one-wallet wallet import  --private-key 0xYourPrivateKey
  

Import with password:

  one-wallet wallet import  --private-key 0xYourPrivateKey --password --set-default
  

List and select wallets

Human-readable list:

  one-wallet wallet list
  

JSON list:

  one-wallet wallet list --json
  

Show current default wallet:

  one-wallet wallet set default
  

Set default wallet:

  one-wallet wallet set default 
  

Wallet storage path

Show where wallets and config are stored:

one-wallet wallet path

Balances

Balance of default wallet:

  one-wallet wallet balance
  

Balance of a named wallet:

  one-wallet wallet balance 
  

Balance of any address:

  one-wallet wallet balance-of 0xAddress
  

Balance as JSON (for scripts/AI tools):

  one-wallet wallet balance-of 0xAddress --json
  

Contract calls and sends

Read-only contract calls

Cast-style without ABI (single quotes to protect parentheses):

one-wallet wallet call 0xToken 'decimals()(uint256)'
one-wallet wallet call 0xToken 'balanceOf(address)(uint256)' 0xAccountAddress
one-wallet wallet call 0xToken 'totalSupply()(uint256)' --json

With preset ABI:

one-wallet wallet call 0xToken balanceOf 0xAccountAddress --abi erc20
one-wallet wallet call 0xNFTContract ownerOf 1 --abi nft
one-wallet wallet call 0xContract getValue --abi-file ./abi.json

Sending ETH and tokens

Native ETH:

one-wallet wallet send 0xRecipientAddress 0.1

Skip confirmation for scripts:

one-wallet wallet send 0xRecipientAddress 0.1 -y

Estimate gas:

one-wallet wallet estimate 0xRecipientAddress 0.1

ERC20 transfer and approve:

one-wallet wallet send 0xToken --method transfer --args 0xToAddress,1000000 --abi erc20 -y
one-wallet wallet send 0xToken --method approve --args 0xSpenderAddress,1000000 --abi erc20 -y

NFT transfer:

one-wallet wallet send 0xNFT --method safeTransferFrom --args 0xFrom,0xTo,1 --abi nft -y

JSON output (tx hash and receipt):

one-wallet wallet send 0xRecipient 0.01 --wallet  --json

Transaction status

Inspect a transaction by hash:

one-wallet wallet tx 0xTransactionHash
one-wallet wallet tx 0xTransactionHash --json

Signing and verification

EIP-191 message signing

Sign with default wallet:

one-wallet wallet sign-message --message "Hello, agent"

JSON output (message, signature, address):

one-wallet wallet sign-message --message "Hello, agent" --json

EIP-712 typed data

From file:

one-wallet wallet sign-typed-data --file ./typed-data.json

From inline JSON:

one-wallet wallet sign-typed-data --payload '{"types":{...},"primaryType":"Mail","domain":{...},"message":{...}}'

Verify signature

Recover signer:

one-wallet wallet verify-signature "Hello, agent" 0xSignatureHex

Verify against expected address:

one-wallet wallet verify-signature "Hello, agent" 0xSignatureHex --expected 0xExpectedAddress

Passwords, encryption, and sessions

Password management

Encrypt existing wallet:

  one-wallet wallet set-password 
  

Remove encryption:

  one-wallet wallet remove-password 
  

Lock (clear session cache):

  one-wallet wallet lock
  

Environment variables

Key variables:

| Variable | Description | |----------|-------------| | ONE_WALLET_HOME | Override config directory (default: ~/.one-wallet). | | ONE_WALLET_RPC_URL | Override RPC URL. | | ONE_WALLET_CHAIN_ID | Override chain ID (for custom RPC). | | ONE_WALLET_KEY_ | Private key for wallet ; bypasses stored key. | | ONE_WALLET_PASSWORD_ | Password for encrypted wallet ; avoids prompt. | | ONE_WALLET_SESSION_TTL | Session cache TTL in seconds (default: 300). |

Use environment variables in CI or non-interactive scripts to avoid prompts and to keep secrets out of the repository.

Provider configuration

Inspect and set provider:

one-wallet provider info
one-wallet provider list
one-wallet provider set mainnet
one-wallet provider set https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY

Prefer presets for common networks; use custom URLs when the user provides a specific RPC endpoint.

Scripting and JSON mode

When the user wants to integrate one-wallet with other tools or automation:

Always add --json when available to get structured output.

Capture stdout and parse as JSON in the surrounding script or tool.

Combine with password environment variables to avoid interactive prompts.

Examples:

one-wallet wallet balance-of 0xAddress --json
one-wallet wallet tx 0xTransactionHash --json
one-wallet wallet list --json

Safety and best practices

Never hard-code real private keys or passwords in source-controlled files.

Prefer ONE_WALLET_KEY_ and ONE_WALLET_PASSWORD_ environment variables for secrets.

Use --json for automation; omit it for quick human inspection.

Use -y only in scripts or when the user explicitly wants to skip confirmations.

When in doubt about the chain or RPC, call one-wallet provider info before sending transactions.
