Give an AI agent a USDC wallet without exposing private keys

The problem with agent-held keys

Autonomous agents are good at calling tools. They are not good places to store secrets with irreversible financial authority. If an agent prompt, plugin, or runtime leaks a seed phrase, every dollar in that wallet can move.

A managed wallet model keeps the signing surface behind an API. The agent can request a payment, but spending limits, authentication, rate limits, and ledger checks happen before funds move.

The wallet requirements for real bots

A production agent wallet is not just an address. It needs balances, deposits, outbound payments, limits, audit history, and recovery behavior. It also needs to be boring enough that a bot can use it without understanding Solana transaction construction.

That is the gap Viaclave is designed to fill. The bot gets a wallet ID and an API key. Viaclave handles key custody, signing, token balances, stablecoin sends, transaction verification, and Solana settlement.

• The agent should never see or store a private key.
• The operator should be able to cap daily and per-transaction spend.
• Every payment should have a durable record and idempotency behavior.
• Deposits should be verifiable without custom RPC logic.
• External withdrawals should go through the same limits and audit trail.

Create a wallet

Create one wallet for each bot, user, strategy, or internal account you want to track separately. Labels make support and reconciliation easier later.

curl -X POST https://api.viaclave.com/v1/wallets \
  -H "Authorization: Bearer vc_test_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "label": "support-agent" }'

Set spending controls

Caps are especially important for agents because payment behavior may be triggered by tool calls, schedules, or external events. Limits make the wallet useful without making it unlimited.

curl -X PUT https://api.viaclave.com/v1/wallets/wal_abc/limits \
  -H "Authorization: Bearer vc_test_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "daily_limit": 50000000, "per_tx_limit": 5000000 }'

Use separate wallets for separate jobs

Do not put every bot workflow into one shared wallet. Separate wallets make it easier to understand what happened and limit damage when a workflow misbehaves.

• Treasury wallet for operator funds.
• Execution wallet for the bot's daily budget.
• User wallets for deposits and premium balances.
• Provider payout wallet for automated payments.
• Test-mode wallet for testing prompts and code changes.

What the agent can do

• Check balances across supported stablecoins.
• Send USDC, USDT, PYUSD, or EURC to another Viaclave wallet.
• Withdraw stablecoins to an external Solana address.
• Verify inbound Solana transactions before delivering work.
• Swap SOL and USDC through one endpoint.

ROI of managed custody

The ROI is mostly engineering time and risk reduction. A team can spend weeks building Solana key storage, token account handling, RPC polling, retry logic, spending limits, and reconciliation. That work does not differentiate a trading bot, Telegram bot, or market alert product.

A managed wallet lets the team ship the paid workflow first. If users do not pay for the bot, you did not waste a month building wallet plumbing. If users do pay, you can invest later in deeper controls, analytics, and compliance processes.
