Crypto deposits explained: USDT TRC-20, BTC, ETH and SOL
Which network to use, why the memo and network selection matter, how confirmations work and what to do if a deposit does not show up straight away.
Key takeaways
- USDT on TRC-20 is the cheapest and fastest option for most players.
- Sending on the wrong network is the number one cause of lost deposits.
- Deposits credit after network confirmations, not at the moment you press send.
- Every deposit address is generated per payment — never reuse an old one.
Depositing crypto is simple once, and confusing the first time. The entire risk sits in one decision — which network you send on — so it is worth two minutes of reading before you move any funds.
Choosing a coin and network
| Asset | Network | Typical fee | Typical arrival |
|---|---|---|---|
| USDT | TRC-20 (Tron) | ~1 USDT | 1–3 minutes |
| BTC | Bitcoin | Variable, often high | 10–60 minutes |
| ETH | Ethereum | Variable, gas dependent | 1–5 minutes |
| SOL | Solana | Fractions of a cent | Under a minute |
For anything under a few hundred USDT, TRC-20 USDT or SOL are the sensible defaults: fees are negligible and confirmation is quick. Bitcoin is fine for larger amounts where a fixed network fee is a small share of the total, but it is a poor choice for a 20 USDT top-up.
How the deposit flow works
- 1Pick your asset and network in the deposit panel.
- 2A unique address (and QR code) is generated for that specific payment.
- 3Send the amount from your wallet or exchange on the matching network.
- 4The payment processor watches the chain and waits for confirmations.
- 5Your balance is credited automatically and a confirmation email is sent.
Why it is not instant
Pressing send broadcasts a transaction; it does not finalise it. A blockchain confirms transactions in blocks, and platforms wait for a set number of confirmations before crediting, because a transaction with zero confirmations can still be replaced. That waiting period is protection, not delay for its own sake — it is what stops double-spend attacks from draining a platform, which is ultimately what keeps your own balance payable.
Common problems and fixes
- Nothing arrived after 30 minutes — check the transaction hash on a block explorer first. If it shows unconfirmed, the network is congested and you simply need to wait.
- You sent less than the quoted amount — under-payments may need manual review. Send your transaction hash to support.
- You sent after the address expired — the funds are still traceable. Provide the hash; the deposit can be matched manually.
- You used the wrong network — stop and contact support with the hash before doing anything else. Recovery is sometimes possible and always slower than getting it right the first time.
Card and bank funding
If you do not already hold crypto, the fiat on-ramp converts a card payment into crypto and delivers it into your balance in one flow. Rates and fees are set by the on-ramp provider and shown before you confirm, so you always see the final credited amount up front.
