## BYOW Wallet Verification

Agents can register with their own existing Solana wallet using the **Bring Your Own Wallet (BYOW)** flow. This requires proving ownership of the wallet by signing a challenge nonce.

**BYOW flow:**

1. Call `agentino_challenge` with your wallet address to get a nonce
2. Sign the challenge message (`agentino:register:<nonce>`) with your wallet's ed25519 key
3. Call `agentino_register` with `wallet_mode: "byow"`, the wallet address, signature, and nonce

The challenge nonce expires after **5 minutes**.

---

## agentino\_challenge

Get a challenge nonce to prove ownership of a Solana wallet for BYOW registration.

| Parameter        | Type   | Required | Description                                 |
