| description | Buy or sell Backed xStocks (tokenized equities, e.g. TSLAx) on TON using jetton addresses from the xStocks API and TON MCP swap tools. Use when the user asks for xStocks, xStock, TSLAx, stock tokens on TON, or buying/selling equity jettons via Omniston. |

xStocks on TON (buy / sell)
Backed xStocks are jettons on TON. Resolve the jetton master from the public xStocks API, then use the same quote → execute flow as ton-swap, with routing preferences learned from real Omniston behavior.
Critical: USDT is the only working swap pair.
Omniston consistently returns no quote for TON → xStock and xStock → TON routes.
All xStock buys and sells must go through USDT. If the user lacks sufficient USDT, buy USDT with TON first (see §Pre-fund USDT below).

Resolve the TON jetton master for an xStock
-
By symbol (e.g. TSLAx): fetch via curl (not WebFetch — the xStocks API returns 403 for non-standard user-agents):
curl -s "https://api.xstocks.fi/api/v2/public/assets/{symbol}"
(production base: https://api.xstocks.fi/api/v2 — see xStocks API).
-
In the JSON, find deployments[] where network is "Ton". Use that object's address as the jetton master for MCP (fromToken / toToken).
-
Optional: curl -s "https://api.xstocks.fi/api/v2/public/assets" returns all assets with the same deployments shape.
-
Call get_jetton_info with --jettonAddress <jetton_master> to confirm name / symbol / decimals before swapping.
MCP tools
| Action | Tools |
|---|
| Pre-fund USDT | get_jetton_balance (USDT) → get_swap_quote (TON → USDT) → emulate_transaction → send_raw_transaction |
| Buy xStock | get_swap_quote (USDT → xStock) → emulate_transaction → send_raw_transaction |
| Sell xStock | get_jetton_balance (xStock) → get_swap_quote (xStock → USDT) → emulate_transaction → send_raw_transaction |
| Verify | get_jetton_info, get_transaction_status, get_jetton_balance |
Amounts for get_swap_quote are human-readable strings (respect jetton decimals from get_jetton_info).
CLI argument names (exact)
| Tool | Arg | CLI flag |
|---|
get_jetton_info | jettonAddress | --jettonAddress |
get_jetton_balance | jettonAddress | --jettonAddress |
get_swap_quote | fromToken | --fromToken (use "TON" for native TON, jetton master address for tokens) |
get_swap_quote | toToken | --toToken |
get_swap_quote | amount | --amount (human-readable) |
get_swap_quote | slippageBps | --slippageBps (default 100 = 1%) |

send_raw_transaction | messages | --messages (same JSON array) |
get_transaction_status | normalizedHash | --normalizedHash |
Pre-fund USDT (auto, when needed)
Before any xStock trade, check the user's USDT balance:
get_jetton_balance for the USDT master address — use the amount field for comparison.
- If
amount < required amount for the planned buy:
a. Calculate the shortfall (include a small buffer for price movement).
b. get_swap_quote with fromToken = "TON" (the literal string, not an address), toToken = USDT master, amount = shortfall.
c. Confirm with the user: "You need ~X USDT but only have Y. Swap Z TON → X USDT first?"
d. On approval, send_raw_transaction → poll get_transaction_status until completed.
e. Re-check USDT balance before proceeding to the xStock buy.
Buy workflow
- Resolve the Ton jetton master for the xStock symbol (API above).
- Check USDT balance — run Pre-fund USDT if insufficient.
get_swap_quote: fromToken = USDT master, toToken = xStock master, amount = USDT to spend, slippageBps = 100 (1 %).
emulate_transaction with the quote's transaction.messages — verify expected balance changes before sending.
- Show the user: fromAmount, toAmount, minReceived, expiresAt, emulation results, and note the forward TON on router messages (gas).
- Confirm once, then
send_raw_transaction with the returned transaction.messages.
- Poll
get_transaction_status on normalizedHash until completed or failed.
Do not attempt TON → xStock directly. It will return no quote. Always route through USDT.
Sell workflow ("sell all" or fixed amount)
get_jetton_balance for the xStock master → use the returned amount field (already a human-readable decimal string, e.g. "12.5"). Use amountRaw only if a raw integer is needed elsewhere.
- Pass
amount directly as the amount parameter for get_swap_quote — no manual conversion needed.
get_swap_quote: fromToken = xStock master, toToken = USDT master.
emulate_transaction with the quote's transaction.messages — verify expected balance changes.
- Show the user the quote details and emulation results, then confirm.
send_raw_transaction, then poll get_transaction_status until completed or failed.
Do not attempt xStock → TON directly. Always sell into USDT.
Post-trade checks
- If balance reads 0 immediately after a buy, wait a few seconds and re-query; indexers can lag.
- After a sell, confirm USDT balance increased as expected.
Omniston quirks
- "No quote available" — no route at that size / time. Retry after a short wait, or adjust amount / slippage slightly. Do not switch to TON pairing; it won't help.
- Occasional WebSocket errors (e.g. quote ack) — retry
get_swap_quote.
- Quotes expire; if the user waited before confirming, fetch a fresh quote before executing.
Relations
- Execution and confirmation rules:
ton-swap skill.
- Wallet funding and status polling:
ton-balance skill.
- Issuance / redemption outside DEX: xStocks product docs / dashboard — not covered by MCP swap alone.
