Setup a Wallet for your Agent

Give your AI agent a dedicated wallet on Base to hold funds, send payments, sign messages, and interact with onchain protocols securely.

An onchain wallet gives your agent the ability to hold funds, authorize transactions, and sign messages. Without one, your agent can read data but can’t pay for services, receive payments, or prove its identity.

Why your agent needs a dedicated wallet

An AI agent could generate its own wallet by creating a random private key through prompting, but this is unsafe:

• The private key appears in the agent’s conversation context, where it can be logged, cached, or leaked through middleware
• Any system with access to the agent’s prompt history could extract the key
• If the key is compromised, all funds in the wallet are permanently lost

Dedicated wallet services solve this by managing keys in secure infrastructure that is separated from your agent’s runtime. Your agent can request transactions without ever seeing the private key.

Wallet setup

OpenClaw

Claude Code, Codex, and OpenCode users — the wallet skills below work with any skills-enabled AI coding tool, not just OpenClaw. Run the same npx skills add command from within your coding tool to get the same onchain wallet capabilities.

OpenClaw supports multiple wallet providers. Choose one:

CDP Agentic Wallet

Coinbase’s standalone wallet for AI agents. Authentication is via email OTP — no API keys required. Private keys stay in Coinbase’s infrastructure.

Install the pre-built wallet skills:

Terminal

npx skills add coinbase/agentic-wallet-skills

Then ask your agent to authenticate and start transacting:

Sign in to my wallet with [e-mail]
Send 10 USDC to vitalik.eth
Buy $5 of ETH

Skills include: authenticate-wallet, fund, send-usdc, trade, pay-for-service, and more. Operates on Base.

Bankr

Every Bankr agent gets a cross-chain wallet on Base, Ethereum, Solana, Polygon, and Unichain. Gas is sponsored on supported chains.

Install the Bankr skill from your agent chat:

install the bankr skill from https://github.com/BankrBot/skills

Create a dedicated account at bankr.bot and generate an API key at bankr.bot/api. Don’t use your personal account — keep your agent’s wallet separate.

Sponge Wallet

A multi-chain agent wallet with built-in x402 payments, token swaps, and cross-chain bridges (Base, Ethereum, Solana).

Register your agent to get a wallet immediately:

Terminal

curl -X POST https://api.wallet.paysponge.com/api/agents/register \
  -H "Sponge-Version: 0.2.1" \
  -H "Content-Type: application/json" \
  -d '{"name": "my-agent", "agentFirst": true}'

Store the returned apiKey:

Terminal

export SPONGE_API_KEY=sponge_live_...

AgentKit

AgentKit uses Coinbase’s CDP Agentic Wallet — API-based wallet management with enterprise-grade key security.

TypeScript

import { AgentKit } from "@coinbase/agentkit";

const agentkit = await AgentKit.from({
  cdpApiKeyName: process.env.CDP_API_KEY_NAME!,
  cdpApiKeyPrivateKey: process.env.CDP_API_KEY_PRIVATE_KEY!,
  networkId: "base-mainnet",
});

const wallet = agentkit.wallet;
console.log("Agent wallet address:", wallet.getDefaultAddress());

Python

from coinbase_agentkit import AgentKit, AgentKitConfig

agentkit = AgentKit(AgentKitConfig(
    cdp_api_key_name=os.environ["CDP_API_KEY_NAME"],
    cdp_api_key_private_key=os.environ["CDP_API_KEY_PRIVATE_KEY"],
    network_id="base-mainnet",
))

wallet = agentkit.wallet
print("Agent wallet address:", wallet.default_address)

Your agent requests transactions via the CDP API. Coinbase handles signing and broadcasting. Keys are managed in Coinbase’s secure enclave — your agent never touches them directly.

What your agent can do with a wallet

Once your agent has a wallet, it can:

• Hold stablecoins: receive and store USDC or other tokens
• Send and receive payments: transfer funds to other wallets, pay for API access, or receive payments for services
• Sign messages: cryptographically prove that a message or request came from your agent (used for identity verification)
• Interact with protocols: call smart contracts to swap tokens, provide liquidity, or use other onchain services
