What should you check first?
- Check the asset/network combination in Gemini's withdrawal screen.
- Match the wallet's receiving network and asset exactly.
- Do not assume API withdrawals have the same networks as the web interface; Gemini documents narrower API support.
When should you stop?
A shared Ethereum-compatible address format does not mean a different network is safe to use.
When should you contact support?
For a sent transaction, collect the hash and chosen network. Contact the receiving provider through official support; recovery is not guaranteed.
Use the help centre linked from the exchange's official website. CoinBBank cannot access your account, approve a payment or recover a transfer.
