You can still pay. ROZO Checkout also accepts native coins that Japanese exchanges do list: SOL on Solana, ETH on Ethereum or Arbitrum, POL on Polygon and BNB on BNB Chain. Paste your OpenRouter payment link, pick the coin, and ROZO shows a one-time deposit address with the exact amount. This guide covers which coin to withdraw from each exchange and how to handle Japan's Travel Rule recipient checks honestly.
What each exchange can send that ROZO accepts
From each exchange's official fee page, checked 1 November 2026. Fees change, so read the fee on the withdrawal screen before you confirm.
| Exchange | Coins and networks ROZO accepts | Withdrawal fee |
|---|---|---|
| bitFlyer | SOL on Solana, ETH | SOL free, ETH 0.005 ETH |
| Coincheck | SOL on Solana, ETH on Ethereum, POL on Polygon | SOL 0.01, POL 0.1, ETH from 0.005 (varies with gas) |
| bitbank | SOL on Solana, ETH on Ethereum or Arbitrum, POL on Polygon, BNB on BNB Chain | SOL 0.009, ETH on Arbitrum 0.00042, BNB 0.0016, POL 1.4 |
| GMO Coin | SOL, ETH, BNB on BNB Chain | Free, but minimum withdrawals are 0.1 SOL, 0.1 ETH and 0.01 BNB |
| SBI VC Trade | USDC on Ethereum, SOL, ETH, POL on Polygon | Free |
None of these exchanges sends USDT, and none sends Bitcoin over Lightning. ROZO does not accept on-chain BTC or XRP, so those balances need converting on the exchange first.
For a typical top-up, SOL on Solana is the simplest choice: every exchange above lists it and the fee is low. On bitbank, ETH on Arbitrum is also cheap. ETH on Ethereum works, but the withdrawal fee is high for a small payment.
The Travel Rule step: why the exchange may not send straight to ROZO
Japanese exchanges ask who receives every crypto withdrawal. You register the address first, say whether it is your own wallet or someone else's, and the exchange reviews it. Some details you should know:
- Coincheck and bitFlyer only let you pick a receiving exchange or service from their own approved list, and the free text option for other services was removed in 2025. ROZO is not on those lists.
- bitbank reviews each registered address and decides.
- GMO Coin makes you wait 24 hours after an address is approved before you can send to it.
A ROZO deposit address belongs to ROZO, not to you, and it is created fresh for each payment and expires with its quote. Do not register it as your own private wallet: that would be a false declaration. The route that works and stays honest is the next section.
Step by step: exchange, your own wallet, then ROZO
- Set up a wallet you control for the coin you will use, for example Phantom for SOL or MetaMask for ETH on Arbitrum.
- On your exchange, register that wallet address as your own private wallet and withdraw the coin to it. Wait for any review or waiting period to finish; nothing here is time limited yet.
- In OpenRouter, open Settings then Credits, turn on the crypto option, enter the amount and click Purchase. Copy the payment link it generates.
- Open checkout.rozo.ai, paste the link, and pick the same coin and network, for example SOL on Solana. ROZO shows a one-time deposit address and the exact amount.
- Send exactly that amount from your wallet to the ROZO address. Keep a little of the same coin for the network fee.
- Once the transfer lands, ROZO settles the OpenRouter link. The ROZO payment page shows live status until it does.
If you hold USDC at SBI VC Trade, the same route works with USDC on Ethereum. Sending USDC needs ETH in the same wallet for the network fee, so withdraw a little ETH there too. Ethereum network fees make this a poor fit for small payments.
What it costs
- OpenRouter's own crypto fee, around 5% as listed on OpenRouter's FAQ at the time of writing, is already inside the payment link amount.
- ROZO charges a 1% service fee. For a native coin such as SOL, ETH, POL or BNB, the coin amount also includes an FX spread on the coin price. Both are shown before you send.
- Your exchange charges its withdrawal fee, and your wallet pays a small network fee for the final send.
ROZO is independent and is not affiliated with OpenRouter, Coinbase or any exchange named here. There is no ROZO account and no KYC form on our side. Your exchange's own checks still apply.
