What is the minimum?
Whatever shows next to the network under Deposit. Polymarket sets it, and it can change over time and from one network to another. Send a little more, so the minimum is left after the exchange's fee.
Deposit with USDT or USDC
You buy USDT or USDC on an exchange and send it to your deposit address on Layback X. It arrives within minutes and turns into balance by itself.
On Polymarket the balance is in pUSD, a digital dollar: 1 pUSD is worth US$ 1. Your deposit address takes USDT or USDC and converts it to pUSD by itself, with no extra click.
Step 1
Buy USDT or USDC
On your exchange, buy USDT or USDC. Both are worth US$ 1 and turn into pUSD the same way. Buy a little more than you want to deposit: the exchange charges a fee to send, shown before you confirm.
Step 2
On Layback X, click Deposit and pick the network
Click Deposit, on the Deposit to start trading bar or in your account panel. Under Network, pick a network your exchange also offers for the token you bought. Polygon and Tron tend to have the lowest sending fees; on Tron, USDT only. Avoid Ethereum: its sending fee tends to be much higher.
The minimums in this picture are examples: what counts is what shows next to each network in the app, set by Polymarket. Send at least the minimum shown next to the network, after the exchange's fee. Below it, the deposit may not be credited.
Step 3
Copy the deposit address
Below it you see Your deposit address, with a QR code. Click Copy address, or scan the QR code with your exchange's phone app. Changed the network? Copy again: the address may change.
Step 4
On your exchange, send on the same network
On your exchange, look for Withdraw or Send crypto (the name varies). Pick the token, paste the address and, in the network field, choose the same network shown on Layback X. Check the amount and the fee, then confirm.
Same network and address on both screens. Your exchange may name the network differently, such as TRC20 for Tron. Step 5
Wait for the balance to land
With the Deposit window open, the status follows the transfer: Waiting for a deposit to this address…, then Deposit received. Converting to pUSD… and finally Latest deposit completed and credited to your balance. It usually takes a few minutes after the exchange sends. You can close the window: the balance lands either way.
With a balance, it is time for your first bet on the ladder.
If something goes wrong
My exchange does not offer the network I picked
Switch the network on Layback X to one your exchange offers for your token and copy the address again. Polygon, Tron, Solana, BNB Smart Chain, Base and Arbitrum are among the options.
The exchange says it sent and the balance has not landed
Open Deposit on the same network to see the status. If it has been over half an hour, copy the transaction code (hash) from your exchange and contact support at contato@layback.trade.
I sent on the wrong network
Do not send again. Contact support at contato@layback.trade with the transaction hash. Not every transfer on the wrong network can be recovered.
