# Swap TON Tokens

Swap tokens on TON via DEX aggregator. Two-step flow: get a quote, confirm with the user, then execute.

## MCP Tools

| Tool | Required | Optional |
| ---- | -------- | -------- |
| `get_swap_quote` | `fromToken`, `toToken`, `amount` | `walletSelector` |
| `emulate_transaction` | `messages` | `validUntil` |
| `send_raw_transaction` | `messages` | `walletSelector` |
| `get_known_jettons` | — | — |

## Workflow

1. If the user mentions a token by name (e.g., "USDT", "jUSDC"), call `get_known_jettons` to resolve the jetton address
2. Call `get_swap_quote` with `fromToken`, `toToken`, and `amount`
   - Use `"TON"` for native GRAM (ex. TON), or the jetton master contract address for tokens
   - Amount is human-readable (e.g., `"1.5"` = 1.5 GRAM (ex. TON))
3. Call `emulate_transaction` with the quote's `transaction.messages` to dry-run the swap — verify the expected money flow (GRAM (ex. TON)/jetton balance changes) before sending
4. Show the quote details and emulation results to the user and ask one short yes/no confirmation
5. Call `send_raw_transaction` with the transaction params returned by the quote
6. Poll `get_transaction_status` with the returned `normalizedHash` until status is `completed` or `failed` (see `ton-balance` skill). User can ask to skip polling.

## Notes

- Always confirm the swap with the user before executing; prefer the host client's structured confirmation UI when available, otherwise accept natural-language yes/no and do not require a fixed confirmation phrase
- The quote returns transaction messages ready for `send_raw_transaction`
- After execution, poll `get_transaction_status` by default. User can specify whether to check status.
- If no wallet is configured, use the `ton-create-wallet` skill first
