Copy the Coinbase payment link generated by OpenRouter, paste it into ROZO Checkout, and choose USDT on BNB Chain, or another token and network available on both platforms. Before confirming in Binance, check the amount the recipient receives and the ROZO payment deadline.
Why the official checkout can't see your Binance balance
OpenRouter's crypto payments run on a Coinbase-powered checkout that talks to browser wallets: MetaMask, Phantom, and the like. An exchange account is custodial: Binance holds the keys, so there is no wallet to connect and no signature you can produce. The checkout is not broken; it simply speaks a protocol your exchange account does not.
What an exchange can do is withdraw to any address on a supported network. That is the capability ROZO Checkout is built around: it turns the invoice into a deposit address, which is exactly the shape of transaction an exchange knows how to send.
Which network to pick on Binance
To withdraw USDT from Binance to OpenRouter, pick BNB Smart Chain (BEP20) unless you have a reason not to. These are the USDT networks Binance lists that ROZO Checkout also accepts:
| Network (as Binance labels it) | Binance withdrawal fee | Binance minimum withdrawal |
|---|---|---|
| BNB Smart Chain (BEP20) | 0.01 USDT | 5 USDT |
| Polygon POS | 0.03 USDT | 5 USDT |
| Solana | 0.3 USDT | 5 USDT |
| Arbitrum One | 0.3 USDT | 3 USDT |
| Ethereum (ERC20) | 0.4 USDT | 3 USDT |
Figures are from Binance's cryptocurrency fee page on 20 October 2026. Binance says withdrawal fees are set by the network and can change without notice, so check the fee shown in the withdrawal form before you confirm.
If you hold USDC instead, the same page lists USDC on BNB Smart Chain (BEP20) with a 0 USDC fee and a 3 USDC minimum, and USDC on Base with a 0.2 USDC fee and a 3 USDC minimum. ROZO accepts both.
ROZO does not accept Tron (TRC20). Do not pick it for this payment, even though Binance lists it.
ROZO is independent and is not affiliated with Binance.
Step by step: from Binance to OpenRouter credits
- In OpenRouter, open Credits, choose Add credits, pick the crypto option, and copy the generated Coinbase URL. Both payments.coinbase.com/payment-links/pl_* and payments.coinbase.com/payment-sessions/paymentSession_* links are supported.
- Open checkout.rozo.ai, paste the link, and pick USDT on BNB Chain, or the token and network you chose above. Copy the one-time deposit address and the exact amount ROZO shows, and note the payment deadline.
- In the Binance app, go to Assets, then Overview, then Send, and tap Withdraw Asset. On the Binance website, go to Assets, then Overview, click Withdraw, then Withdraw Asset. Choose the token you picked at ROZO, for example USDT.
- Paste the ROZO deposit address and select the network you picked at ROZO, for example BNB Smart Chain (BEP20). The website picks a network from the address you paste, and a BNB Chain address looks the same as an Ethereum or Polygon one, so check that the selected network is the one you chose at ROZO.
- In the app, choose the Receive amount option and enter the exact amount ROZO shows: Binance then adds its network fee on top, so the full amount arrives. With the Withdrawal amount option, Binance deducts the fee from what you type and the payment arrives short.
- Confirm and verify with your passkey or 2FA. Once the transfer confirms on chain, ROZO detects it and settles the OpenRouter link, usually in roughly 30 to 90 seconds. Then check your OpenRouter credits.
Before confirming, check that the ROZO payment window leaves enough time for Binance processing. If you have not submitted the withdrawal and the window is too short, get a fresh quote. If you already submitted it, keep that order and check its status; do not send a second payment.
The three exchange-withdrawal mistakes to avoid
Network or token mismatch: select the same network and token on Binance and ROZO. If you already sent on a different route, check the order or contact support before sending again. Do not assume a matching address means every chain or token is supported.
Fee shortfall: use the recipient amount displayed by Binance after its current withdrawal fee. Adjust the withdrawal only after checking that final amount. Binance lists the network fee and recipient amount in its withdrawal form: https://www.binance.com/en/support/faq/detail/115003670492 . Fees and minimums can change.
Expired or delayed withdrawals: never reuse an old deposit address. If you have already paid, keep the order and contact support about an expired or delayed transfer. If the active payment page explicitly asks for a remaining amount, follow that instruction using its current address, network, token and deadline. Otherwise do not top up or restart payment on your own.
