Aibtc Bitcoin Wallet

Get current network fee estimates:

"What are the current Bitcoin fees?"

Uses get_btc_fees - returns fast (~10 min), medium (~30 min), and slow (~1 hr) rates in sat/vB.

Send BTC

Transfer Bitcoin to an address:

"Send 50000 sats to bc1q..."
"Transfer 0.001 BTC with fast fees to bc1q..."

Uses transfer_btc - requires an unlocked wallet.

Wallet Setup

Before sending transactions, set up a wallet:

1. Create new wallet: wallet_create - generates encrypted BIP39 mnemonic
2. Import existing: wallet_import - import from mnemonic phrase
3. Unlock for use: wallet_unlock - required before transactions

Wallets are stored encrypted at ~/.aibtc/.

Read Operations

Write Operations (Wallet Required)

Wallet Management

Units and Addresses

Amounts: Always in satoshis (1 BTC = 100,000,000 satoshis)

Addresses:

• Mainnet: bc1... (native SegWit)
• Testnet: tb1...

Fee Rates: "fast", "medium", "slow", or custom sat/vB number

Example Workflows

Daily Balance Check

1. "What's my BTC balance?"
2. "Show my recent UTXOs"
3. "What are current fees?"

Send Payment

1. "Unlock my wallet" (provide password)
2. "Send 100000 sats to bc1qxyz... with medium fees"
3. "Lock my wallet"

Multi-Wallet Management

1. "List my wallets"
2. "Switch to trading wallet"
3. "Unlock it"
4. "Check balance"

Progressive Layers

This skill focuses on Bitcoin L1. Additional capabilities are organized by layer:

Stacks L2 (Layer 2)

Bitcoin L2 with smart contracts and DeFi:

• STX token transfers
• ALEX DEX token swaps
• Zest Protocol lending/borrowing
• x402 paid API endpoints (AI, storage, utilities) — safe-by-default with probe-before-pay workflow

See: references/stacks-defi.md

Pillar Smart Wallet (Layer 3)

sBTC smart wallet with yield automation:

• Passkey or agent-signed transactions
• Send to BNS names (alice.btc)
• Auto-boost yield via Zest Protocol

See: references/pillar-wallet.md

Bitcoin Inscriptions

Inscribe and retrieve digital artifacts on Bitcoin:

• Commit-reveal inscription workflow
• Get inscription content and metadata
• Protect ordinal UTXOs from accidental spending

See: references/inscription-workflow.md

x402 Paid APIs

Pay-per-use APIs with automatic micropayments on Stacks L2:

• Discover available endpoints with list_x402_endpoints
• Check cost before paying with probe_x402_endpoint
• Execute endpoints with execute_x402_endpoint (safe-by-default — probes first)
• Send inbox messages with send_inbox_message (use this instead of execute_x402_endpoint for inbox)
• Build new x402 APIs with scaffold_x402_endpoint and scaffold_x402_ai_endpoint

Always probe before executing paid endpoints. Never call execute_x402_endpoint with autoApprove: true without checking cost first.

send_inbox_message — dedicated tool for aibtc.com inbox messages:

• Parameters: recipientBtcAddress (bc1...), recipientStxAddress (SP...), content (max 500 chars), paymentTxid (optional)
• Uses sponsored transactions: sender pays only the sBTC message cost, relay covers STX gas
• Avoids sBTC settlement timeout issues that affect the generic execute_x402_endpoint tool
• Implements the full 5-step x402 v2 payment flow with balance pre-check
• paymentTxid (optional): provide a confirmed on-chain sBTC transfer txid to skip the x402 flow and deliver the message using that txid as payment proof — use for manual recovery when a settlement timeout left the sBTC payment confirmed on-chain but the message undelivered
• Automatic recovery: if retries are exhausted, the tool checks whether any submitted payment txid confirmed on-chain and, if so, resubmits the message automatically — no agent action required

See: references/stacks-defi.md for endpoint catalog See: references/x402-inbox.md for inbox-specific flow details

Genesis Lifecycle

Agent identity and reputation on Bitcoin and Stacks:

• L0: Local agent key generation
• L1: Dual-chain plain-message signatures (btc_sign_message + stacks_sign_message)
• L2: X claim + BTC airdrop activation
• L3: On-chain identity registration via ERC-8004 (register_identity)
• L4: Reputation bootstrapping (get_reputation, give_feedback)
• Active: 5-minute check-ins to maintain reputation and liveness

See: references/genesis-lifecycle.md

Troubleshooting

"Wallet not unlocked"

Run wallet_unlock with your password before sending transactions.

"Insufficient balance"

Check get_btc_balance - you need enough BTC for amount + fees.

"Invalid address"

Ensure address matches network:

• Mainnet: starts with bc1
• Testnet: starts with tb1

See: references/troubleshooting.md
