walletš Base Wallet - Crypto Identity for AI Agents. Create wallets, sign messages (SIWE), send transactions programmatically. No browser extensions, no human int...
Install via ClawdBot CLI:
clawdbot install walletEvery autonomous agent needs a wallet. Create one without human help.
TL;DR: Programmatic wallet creation on Base/Ethereum. SIWE auth, balance checks, transactions.
Create and manage Base chain (Ethereum-compatible) wallets programmatically.

| Use environment variables for private keys | Store private keys in plain text files |
| Set wallet files to chmod 600 | Commit wallet files to git |
| Use --env mode (recommended) | Use console.log(privateKey) |
| Back up mnemonics offline | Share private keys or mnemonics |
# Output as environment variable format (safest)
node scripts/create-wallet.js --env
# Output example:
# export WALLET_ADDRESS="0x..."
# export PRIVATE_KEY="0x..."Then copy to your shell or .env file.
# Only if you need file-based storage

An AI agent uses the wallet to handle customer refunds or loyalty token distributions on a decentralized platform. It autonomously verifies user requests via SIWE signatures and processes micro-transactions without human intervention, ensuring 24/7 service availability.
A content platform employs an AI agent to automatically distribute earnings to creators based on engagement metrics. The wallet enables secure, programmatic payments on Base, handling transactions in real-time while logging all activities for audit compliance.
In logistics, an AI agent uses the wallet to sign and verify product authenticity data on a blockchain. It autonomously creates wallets for new suppliers, signs SIWE messages for access control, and records transaction logs to ensure tamper-proof audit trails.
An AI agent manages a decentralized finance portfolio by programmatically executing trades and staking operations on Base. It leverages the wallet to sign transactions, check balances, and interact with smart contracts, optimizing returns without manual oversight.
A gaming platform uses an AI agent to distribute NFT rewards to players based on in-game achievements. The wallet handles the creation of player-specific wallets, signs messages for authentication, and sends transactions to mint and transfer NFTs autonomously.
Offer a subscription-based platform where developers integrate the wallet skill into their AI agents for Web3 functionalities. Revenue comes from tiered plans based on transaction volume, support levels, and advanced features like enhanced audit logging.
Monetize by charging a small percentage fee on each transaction processed through the wallet skill in AI agents. This model aligns with high-volume use cases like micro-payments or DeFi operations, generating revenue proportional to agent activity.
Provide enterprise-grade packages that include the wallet skill with added security audits, compliance reporting, and custom integration support. Target industries like finance or supply chain where secure, autonomous wallet management is critical for regulatory adherence.
š¬ Integration Tip
Always store private keys in environment variables and use the --env mode for wallet creation to prevent security breaches; avoid file-based storage unless absolutely necessary.
