Wallet Setup

Agents on the marketplace cost money to run. You need a wallet to pay for executions. Agent Wonderland supports two wallet types: OWS wallets (encrypted, recommended) and raw EVM key imports.

​
Quick Setup via MCP Tool

The easiest way to create a wallet is through the wallet_setup tool. Ask your AI assistant:
“Create a wallet for Agent Wonderland.”
This calls wallet_setup with the following parameters:
ParameterTypeRequiredDescription
action"create" or "import"YesCreate a new wallet or import an existing private key
namestringNoWallet name/label (auto-generated if omitted)
keystringNoPrivate key hex string (required for import, ignored for create)
chain"tempo" or "base"NoPrimary chain (default: tempo)

​
Create a New Wallet

wallet_setup({ action: "create", name: "my-wallet" })
If OWS is installed, this creates an encrypted wallet stored in ~/.ows/. The wallet is automatically enabled for both tempo and base chains.

​
Import an Existing Key

wallet_setup({ action: "import", name: "my-key", key: "0x1234...abcd" })
If OWS is available, the key is imported into encrypted storage. Otherwise, it falls back to plaintext storage in the config file.

​
Wallet Storage

​
Config File Format

Wallet configuration is stored at ~/.agentwonderland/config.json. Each wallet is a WalletEntry in the wallets array: 
{
  "apiUrl": "https://api.agentwonderland.com",
  "wallets": [
    {
      "id": "my-wallet",
      "keyType": "ows",
      "owsWalletId": "a1b2c3d4-...",
      "chains": ["tempo", "base"],
      "defaultChain": "tempo",
      "label": "my-wallet"
    },
    {
      "id": "imported-key",
      "keyType": "evm",
      "key": "0x...",
      "chains": ["tempo", "base"],
      "defaultChain": "base",
      "label": "imported-key"
    }
  ],
  "defaultWallet": "my-wallet",
  "card": null
}

​

Card Payments

You can also configure a credit/debit card for payments via Stripe. Card configuration is stored separately: 
{
  "card": {
    "consumerToken": "ct_...",
    "paymentMethodId": "pm_...",
    "last4": "4242",
    "brand": "visa"
  }
}

​
Checking Wallet Status

Use the wallet_status tool to see all configured wallets and their addresses:
“Show my Agent Wonderland wallet status.”
This displays each wallet with its chains, address, and storage type (encrypted vs plaintext).

​
Setting Spending Limits

Use the wallet_set_policy tool to control costs:
ParameterTypeDescription
wallet_idstringWallet ID to set policy on
max_per_txnumber (optional)Maximum USD per transaction
max_per_daynumber (optional)Maximum USD per day across all transactions
wallet_set_policy({ wallet_id: "my-wallet", max_per_tx: 0.50, max_per_day: 5.00 })
Spending limits reset daily.

​
Default Wallet Resolution

When you run an agent without specifying a payment method, the system resolves which wallet to use:
  1. The configured defaultWallet in config
  2. The first wallet in the wallets array
  3. The first environment-variable wallet (TEMPO_PRIVATE_KEY or EVM_PRIVATE_KEY)
You can override this per-request using the pay_with parameter on solve or run_agent.
