How to deposit USDT, USDC and other tokens (choosing the right network)

Use the Deposit page of the client portal (app.jafx.com). The key rule is to send only the token you selected, on the network you selected. Your deposit is credited to your wallet automatically once it is confirmed on the blockchain.

Token networks

• ERC20 tokens run on Ethereum.
• TRC20 tokens run on TRON.
• SPL tokens (shown as "SOL" or "Solana") run on Solana.
• Base tokens run on Base.

The same asset, such as USDT, can exist on several networks. These networks are not interchangeable. A token sent on one network can only be received on that same network.

Supported assets and networks

Do not send any other token or coin, even on one of these networks. For Bitcoin, see How to deposit Bitcoin.

How to deposit

1. Sign in at app.jafx.com and open Deposit.
2. Choose the asset and network you will send. For example, choose "USDT (TRON)" only if you will send USDT on TRON.
3. Enter the amount and continue. The page shows the limits for the method you chose: the minimum is $10 and there is no maximum.
4. In your own crypto wallet, select the same asset and the same network yourself. Do not rely on a default. If you are unsure which network your wallet or exchange uses, ask them first.
5. Send the payment to the address shown, within 1 hour. If no funds are sent in that time, you will see "This deposit session has expired." Start a new deposit and use the new details. Each address is for one deposit only: for every new deposit, start a new deposit request and use the new address.
6. Check Transaction History for your deposit.

Before you press send, check: - The token matches the one you selected. - The network matches the one you selected. - You copied the address shown for this deposit session. - The amount that arrives, after fees, is at least the minimum.

If you see "The crypto gateway is temporarily unavailable. Please try again.", do not send anything. Wait a few minutes and start a new deposit.

Wrong network or unsupported token

The deposit screen warns: "Only send <asset> on <network> — other tokens or networks can't be recovered." A token sent on a different network from the one you selected is not credited. This also applies to a token that is not on the list above, such as USDC sent on TRON.

Minimum and fees

Token deposits must be at least $10 (USD equivalent); there is no maximum. The blockchain network charges a fee, and your wallet or exchange may charge one too. This means the amount that arrives can be lower than the amount you send. If you send close to the minimum, the amount received may fall below it. If that happens, top up the deposit by sending the difference to the same address. Send enough that the amount arriving is still above the minimum. See Deposit methods, minimum deposit and fees.
