bitFlyer is one of Japan's largest and longest-running exchanges, and like every Japanese platform it trades mostly in JPY — so your yen is first converted before you withdraw. The Japanese-specific gate is the FSA travel-rule declaration: bitFlyer asks you to register the destination wallet and declare who owns it before crypto can leave. Clear that once, pick the TRON network, and your USDT lands on Fish & Chips in a couple of minutes for a flat 1 USDT fee — we never charge anything on deposits.
TL;DR: bitFlyer → buy/convert to USDT → Send/Withdraw → USDT → TRON (TRC-20) (not ERC20) → register your TronLink address (starts with
T) and complete the travel-rule declaration → arrives in ~2 minutes → connect at fishnchips.io/wallet.
Step 1 — Install TronLink and copy your address
On mobile, install TronLink from the App Store or Play Store. Create or restore a wallet and write the 12-word recovery phrase down offline. If you lose it, the funds are gone — bitFlyer support cannot recover a self-custodial wallet.
Your address starts with a capital T and is 34 characters long. Tap it in TronLink to copy.
Step 2 — Withdraw from bitFlyer
- Sign in to bitFlyer. If you hold JPY, buy or convert to USDT first (JPY pairs dominate on Japanese exchanges, so this is usually a one-tap conversion).
- Go to Send/Withdraw and select USDT.
- Network: choose TRON (TRC-20). This is the single step that can lose your money.
- Register your TronLink address and complete bitFlyer's travel-rule declaration — you'll confirm the wallet is your own, self-custodial wallet. Confirm with 2FA and the email/app prompt bitFlyer sends.
- Enter the amount and submit. Approve the final confirmation.
| Network | bitFlyer fee | Arrival time | Works for Fish & Chips? |
|---|---|---|---|
| TRON (TRC-20) | ~1 USDT | ~2 min | ✅ Yes |
| ERC20 (Ethereum) | 3–15 USDT | 1–5 min | ❌ Lost funds |
Step 3 — Confirm on Fish & Chips
Open fishnchips.io/wallet, tap Connect Wallet, and approve TronLink. Within about a minute of the Tron block confirming, the deposit posts to your balance at 1 USDT = 1,000 points. Your first-ever deposit also triggers the welcome bonus — a 50% match capped at 5,000 points.
You can verify the transfer on Tronscan: search your address and the latest inbound USDT transfer should read "Success".
Common mistakes to avoid
- Skipping the travel-rule declaration. bitFlyer will not release crypto to an external wallet until the destination is registered and the ownership declaration is done. Do it once and it's remembered.
- Leaving the network on ERC20. Always re-check TRON (TRC-20) before you confirm — other networks never arrive on Fish & Chips.
- Forgetting to convert JPY first. bitFlyer trades in yen; buy USDT before you try to withdraw.
- Sending dust amounts. Fund at least 10 USDT so you can comfortably withdraw winnings later (our minimum cash-out is 10 USDT).
- Pasting an exchange address. Use your own TronLink address, never another exchange's deposit address.
Once your first deposit lands, every future one takes about 30 seconds because both TronLink and bitFlyer's registered-address list remember the details. New here? Read the TRC-20 vs ERC-20 explainer before you send, or head to the arcade lobby for Fish Hunter and Dragon King.
Frequently asked questions
How do I pick the TRC-20 network on bitFlyer?
On bitFlyer, go to Send/Withdraw, select USDT, then choose the network. Pick 'TRON (TRC-20)' rather than Ethereum (ERC-20). TRC-20 is the same Tron rail Fish & Chips accepts and the cheapest option for USDT. If USDT isn't listed on your account tier, convert via a listed asset or use an exchange that carries USDT.
Why does bitFlyer ask who owns the destination wallet?
bitFlyer is regulated by Japan's FSA and follows the travel rule, so before it sends crypto to an external wallet it asks you to declare the destination — whether it's your own wallet and whether it's self-custodial. Self-custodial wallets like TronLink are supported: register the address once, answer the ownership questions, and reuse it on every future deposit.
What is bitFlyer's withdrawal fee for USDT TRC-20?
Around 1 USDT, flat, on the TRON (TRC-20) network. It's the same fee whether you send 20 USDT or 2,000 USDT, which makes Tron the cheapest way out — far below any Ethereum (ERC-20) fee.
What is bitFlyer's minimum USDT TRC-20 withdrawal?
bitFlyer's crypto withdrawal minimums are small (a few USDT), but to actually withdraw winnings later you need at least 10 USDT on Fish & Chips (our minimum cash-out), so funding 10 USDT or more from the start is the cleanest path.
