Coinbase does not support the Binance Smart Chain network, and therefore, we do not have access to these funds. As a result, we are unable to recover the asset you mistakenly sent using an unsupported network. As expressed on the pop-up message under your receiving wallet address, we only support the ERC20 version of the token (while the Binance Smart Chain uses the BEP20 protocol), and any transaction sent through a different network might cause the loss of the asset.
I understand this is a frustrating experience. I wish there was more we could do, but we don’t have the ability to recover these funds at this time. In the future, I recommend sending a small test amount before sending any large amounts, especially when using an unfamiliar network like the Binance Smart Chain.
