Spot trading on a non-custodial wallet
Nobody else controls your funds. Keys stay on your phone, and you sign every trade. The point is that the balance stays in your wallet, not an exchange account — so we cannot freeze or move it, because we never hold it.
- Nobody but you controls your funds — the key never leaves the device
- Liquid USDT pairs on BSC from the wallet catalog
- Price and fee are shown before you sign
- Every fill is a BscScan transaction you can verify
Why non-custodial?
On a centralized exchange you deposit coins with them, and they move the ledger for you. If the account is closed or withdrawals stop, you do not hold the key. In Taccoin the balance sits on-chain at your address. Spot is a DEX swap you sign in the app; we only prepare the quote. That is why there is no internal order book: we do not match you against another user, and we do not hold the trade until it fills.
What happens on buy or sell?
The app requests a quote from a DEX aggregator on BSC (0x, then LiFi if needed). Allowed slippage is 1%. If price impact exceeds 3% the trade is blocked until you reduce the size. After you approve, the swap is signed on your phone and broadcast. This is an on-chain swap, not an internal matching engine.
Fees and who pays gas
The platform fee is taken from the USDT amount and shown in numbers before you confirm. The default is 0.30% and can be changed in admin. Network gas on BSC is paid in BNB. When gas cover is on, the treasury may send a small BNB amount so you can trade without holding BNB first, within a daily cap. If cover is unavailable the action stays locked.
Where do prices and the tape come from?
The markets list shows live prices for eight visible coins, plus your favorites. The chart uses public market candles for the pair. The recent-trades tape is public DEX prints on PancakeSwap via GeckoTerminal — not a synthetic book inside the app. We do not show illustrative prices.
What we do not do
We do not hold your funds or keys. We do not match your orders against other Taccoin users. We do not hide the fee inside the price. We do not invent an order book. Futures in the menu is marked coming soon and is not live trading.
Android may ask you to allow installs from this source.

Frequently asked questions
Can Taccoin move my funds?
No. The wallet is non-custodial: the private key is on your device. No trade leaves without your signature. Support never asks for the recovery phrase and cannot recover it.
Is this Binance spot trading?
No. The trade executes on BNB Smart Chain through a DEX aggregator. The chart may use public market candles for display only; it is not a centralized-exchange trading account.
Where do I verify a fill?
After execution you get a transaction hash. Open it on BscScan. The in-app history lists fills tied to your wallet only.
Why can Buy or Sell stay locked?
If liquidity cannot cover the size, gas cover is unavailable, the wallet is watch-only, or simulation rejects the transaction. The form shows a short reason instead of a raw node error.
Can a watch-only wallet trade?
No. Watch-only has no private key, so send, swap, and spot stay disabled.
