There is a shorter path. ROZO Checkout accepts a plain exchange withdrawal: paste your OpenRouter payment link, pick the coin and chain you actually hold on Binance, and it shows a deposit address you can withdraw to directly from the exchange. When the transfer confirms, ROZO settles the original Coinbase invoice on the right network, token, and amount.
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.
Step by step: from Binance to OpenRouter credits
First, in OpenRouter, open Credits, choose Add credits, pick the crypto option, and copy the generated Coinbase payment link (payments.coinbase.com/…).
Second, open checkout.rozo.ai, paste the link, and choose the coin and network you hold on Binance — USDC on Solana, Base, or BNB Chain are all good choices with low withdrawal fees. ROZO shows a deposit address and the exact amount.
Third, in Binance, go to Withdraw, select the token, paste the deposit address, and double-check the network selector matches the one you picked at ROZO — the network mismatch is the one mistake that genuinely hurts. Send the exact amount shown.
When the withdrawal confirms on-chain, ROZO pays the Coinbase invoice and your OpenRouter credits appear. No wallet, no seed phrase, no bridging.
The three exchange-withdrawal mistakes to avoid
Network mismatch: if ROZO expects USDC on Solana and Binance sends it on BNB Chain, the payment cannot match. Always make the exchange's network dropdown agree with the chain you chose at checkout.
Fee shortfall: Binance deducts its withdrawal fee from the amount you type, so the address can receive slightly less than the invoice needs. Add the withdrawal fee on top so the received amount equals what ROZO asked for.
Slow withdrawals against a ticking clock: exchange withdrawals sometimes queue for manual review. If a deposit window is about to expire, wait and request a fresh quote instead of sending late — late transfers to expired one-time addresses are the classic way funds end up stuck in support-ticket limbo.
