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 TON, or the jetton master contract address for tokens
   • Amount is human-readable (e.g., "1.5" = 1.5 TON)
3. Call emulate_transaction with the quote's transaction.messages to dry-run the swap — verify the expected money flow (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
