Transferring Ethereum (ETH) from a centralized exchange like bitFlyer to a non-custodial wallet such as MetaMask is a fundamental step for anyone looking to participate in the decentralized web — whether for NFT purchases, DeFi interactions, or long-term asset management. This guide walks you through the entire process with clear, step-by-step instructions optimized for both mobile and desktop users.
Whether you're a beginner or just new to this specific transfer flow, you’ll find everything you need to know — from address registration and security best practices to handling common issues like minimum withdrawal amounts and network fees.
📱 Mobile: Sending ETH from bitFlyer to MetaMask
Let’s start with the mobile app experience. The process is straightforward and can be completed in just a few minutes.
Step 1: Register Your MetaMask Address on bitFlyer
Open the bitFlyer app, then follow these steps:
- Tap “入出金 (Deposit/Withdrawal)” at the bottom menu.
- Select the top tab “仮想通貨 (Cryptocurrency)”, then choose ETH.
- Tap “出金 (Withdraw)”.
- Choose “外部イーサアドレス登録 (Register External Ethereum Address)”.

You’ll receive a confirmation email from bitFlyer. Click the link in the email to proceed.
Step 2: Copy and Paste Your MetaMask Wallet Address
Now it’s time to input your personal wallet address:
- In MetaMask, tap your wallet name — this will reveal your public address (a string starting with
0x...). - Tap “Copy” to save it to your clipboard.
- Back in the bitFlyer app, paste the address into the “イーサアドレス (Ethereum Address)” field.
- Use a recognizable label like “My MetaMask Wallet” so you can easily identify it later.
- Tap “Next”.
Next, confirm your ownership and usage intent:
- Select “お客様本人 (You Yourself)”.
- Choose “プライベートウォレット等 (Private Wallet, etc.)”.
- Set country/region to Japan, then tap “Next”.
- Review the details, check the confirmation box, and tap “Save”.
✅ Pro Tip: Always double-check that the pasted address matches exactly. A single incorrect character could result in permanent loss of funds.
Step 3: Initiate the ETH Transfer
Once your address is registered:
- Go back to “入出金 → 仮想通貨 → ETH → 出金”.
- Select the MetaMask address you just added.
- Enter the amount of ETH you wish to withdraw (ensure it meets the minimum requirement — see FAQ below).
- Tap “出金” twice — once to confirm the amount, and again on the final screen to complete the transaction.
Your ETH is now on its way to MetaMask! Depending on network congestion, it should arrive within a few minutes.

Q: Why can’t I send ETH to my existing MetaMask address?
A: Since June 2023, Japanese exchanges like bitFlyer have implemented the Travel Rule, which requires sender and recipient information for compliance with anti-money laundering regulations. Even if you’ve sent before, you may need to re-register the address with updated ownership verification.
Q: What is the minimum amount I can withdraw?
A: bitFlyer requires a minimum withdrawal of 0.001 ETH. Attempting to send less will result in an error.
Q: Are there withdrawal fees?
A: Yes — bitFlyer charges a flat fee of 0.005 ETH per withdrawal, regardless of amount. At $3,000 per ETH, that’s $15 per transaction. To minimize costs, consider batching transfers instead of sending small amounts frequently.
Q: Is it safe to copy and paste wallet addresses?
A: Yes — in fact, it’s strongly recommended. Manually typing a 42-character hexadecimal address increases the risk of typos. Always use copy-paste and verify the first and last few characters match.
⚠️ Important Security Reminders
- Never share your private key or seed phrase — MetaMask will never ask for it.
- Always verify that you're on the official metamask.io website when downloading or accessing support.
- Use two-factor authentication (2FA) on your bitFlyer account.
- Test with a small amount first before transferring large balances.
