Trade tokens on Canton Network from your terminal.
Non-custodial. Local-first.
trngle is a self-contained terminal application for swapping tokens on Canton Network. It connects to your Loop wallet, fetches live quotes from the operator, and signs every transaction locally with your private key. Nothing is custodial — your keys never leave your machine.
Testnet only — this release trades test tokens on Canton Network testnet. Mainnet support is planned.

- You request a quote — trngle calls the operator API
- You review the price in your terminal
- On confirmation, trngle signs the transaction locally and submits it on-chain via your Loop wallet
- The operator settles the trade — both sides receive their tokens
The operator provides liquidity and settlement. trngle provides the interface. All signing happens on your machine.
trngle can run an optional REST API on localhost for programmatic trading. Enable it during setup or with the --api-only flag.
trngle --api-only --port 8080
Endpoints include /health, /balances, /trade/quote, /trade/{id}/confirm, /trades, /transfers, and a /ws WebSocket for real-time trade events. See docs/API.md for full documentation.
Config is stored at ~/.trngle/config.json. Trade history is in ~/.trngle/history.db.
