COINXon Solana
Solana charges this to move your coins. It is not our fee, and it is already inside the amount you are quoted.
No line added at the end, no percentage on top. What the quote says is what settles.
One side of this pair cannot be quoted firm, so the price is set when your deposit confirms.
No account, no document, no limit tied to who you are — at any amount on this pair.
How to
Three steps, and only the second one involves your wallet.
Type what you want to send, then paste the address that should receive the COINX. We check it against Solana before anything is created.
We generate an address for this exchange only. Send from your own wallet, whenever you are ready — nothing moves before you do, and there is no account to fund first.
Once ERC20 confirms your deposit, the exchange and the payout take seconds. The COINX goes straight to your address — no balance, no withdrawal step.
What you actually get
The payout network fee is a fixed amount, so the smaller the swap, the more of it that fee eats — which is why this table exists instead of one headline rate.
| You send | You get | Effective rate | Cost of size |
|---|---|---|---|
| 50 USDT | 0.2512079 COINX | 0.00502416 | −1.48% |
| 100 USDT | 0.5065985 COINX | 0.00506598 | −0.66% |
| 500 USDT | 2.5497 COINX | 0.00509945 | best rate on this pair |
Quoted by the desk at , refreshed every few minutes. The percentage compares each line's effective rate with the best one in this table — it is the price of swapping small, not a fee we charge.
The two sides
Tether (USDT) is a stablecoin designed to track the US dollar, issued on many blockchains at once. The network matters as much as the ticker: USDT on TRC20, ERC20 or BEP20 are not interchangeable at the address level. More about Tether.
On this pair it moves over ERC20 — an address there starts with 0x — 42 characters.
USDT also exists on other networks — different addresses, not interchangeable: Aptos, Arbitrum, AssetHub, Avalanche, BEP20, Celo.
On this pair it moves over Solana — an address there 32 to 44 characters, no 0x prefix.
COINX lives on a single network here, so there is no wrong-chain version of it to confuse it with.

FAQ
Using it
1.799 USDT right now. The desk sets it live and it moves with the Solana network fee — below it, that fee would eat the swap. There is no fixed maximum on this pair.
A Solana address you control — it 32 to 44 characters, no 0x prefix. COINX exists on several networks; an address from another one looks valid and the coins would be unrecoverable, so we check it against Solana before creating anything.
Around 10-60 minutes end to end, as forecast by the desk right now. Most of that is ERC20 confirming your deposit — the exchange and the payout themselves take seconds.
Money & privacy
Not on this pair: it is floating only, because one of the two sides cannot be quoted firm. The amount is set when your deposit confirms.
Two things come out: the Solana network fee for sending your payout — 0.00146 COINX right now — shown on its own line, and our margin, which is already inside the rate. Nothing is added after you confirm.
No. There is no account to create and we never ask for identity documents, at any amount. The one case where a swap can be held is spelled out in the AML policy rather than hidden.
On-chain, yes: ERC20 and Solana are public ledgers, so the deposit and the payout are visible to anyone, like any other transaction on them. What nobody can link them to is an identity: there is no account, no document and no request log here — the privacy policy names the only parties in the path.
Every order takes an optional refund address, and it is worth filling in. If the exchange cannot go through — a deposit under the minimum, a pair that stops being quoted, or the one documented case of a flagged deposit where the law allows a return — the deposit goes back to that address, minus what the network charges to send it; we charge nothing for a refund. Without a refund address, a return has to be arranged by hand through support. The order page tells you which situation you are in; nothing is decided silently.
