SaturnSwap Market Swap Operator

Sign and submit market swap transactions. This is an OPERATOR skill — every action requires explicit user confirmation.

Prerequisites

• An unsigned transaction from saturnswap-market-swap (transactionId + hexTransaction)
• A wallet signing key (PAYMENT_SKEY_HEX or PAYMENT_SKEY_CBOR env var, or MCP wallet)

Flow

1. Receive unsigned tx from the guidance skill
2. Sign locally using CSL or MeshJS (never send private keys to the API)
3. Confirm with user — show tx ID and ask for explicit "submit" confirmation
4. Submit — call submitOrderTransaction with signed hex
5. Report result — show transaction ID or error

Scripts

Sign and Submit

node scripts/sign-and-submit.js --address <bech32> --txid <transactionId> --hex <unsignedHex>

Signs the transaction using the configured wallet key, then submits to SaturnSwap.

Safety Rules

• NEVER auto-submit — always require explicit user confirmation before submission
• NEVER log or display private keys
• Verify the transaction ID matches what the user approved in the guidance step
• If signing fails, do NOT retry automatically — report the error
• After submission, report the on-chain transaction ID for verification
