Can I recover unsupported ERC20 cryptos sent to Coinbase?
If you have transferred any digital asset to your Coinbase account that Coinbase does not currently support, then there is no way to recover these assets. However, if a previously unsupported ERC20 becomes available on Coinbase, any assets of that cryptocurrency that you previously transferred to your Coinbase account will automatically become accessible in that account. It is always important to check the list of assets supported by Coinbase before transferring any asset to a Coinbase account.
If you are looking for a place to store digital assets that are not available on Coinbase, CoinbaseWallet is a great option. It is available in all countries, supports over 500 cryptocurrencies including every ERC20 token, and is available as both a web browser extension and a mobile app.
Please know that Coinbase is constantly adding support for new assets as quickly as possible. For regulatory reasons, we may not be able to support trading of every cryptocurrency asset, but we believe we can enable access to most assets for basic wallet functionality (sending, receiving, and holding).
Brian Armstrong, our CEO, wrote a blog post about our plans to massively increase the number of supported assets on Coinbase that you can read here. Our goal is for Coinbase users to have safe and legal access to every cryptocurrency possible.
If you have transferred an unsupported asset to your Coinbase account and you later discover that Coinbase has added support for that asset (please refer to the current list of supported assets here), and your previously transferred coins do not appear in your Coinbase account, then you should contact Coinbase Support and we will try to help you recover your previously transferred assets.
Why am I able to send unsupported crypto to Coinbase?
The ERC20 protocol does not allow Coinbase to reject unsupported ERC20 deposits, and other exchanges or wallets are not able to determine if we support a specific cryptocurrency. As a reminder, please remember to verify that you are sending to the correct Ethereum address when depositing ERC20 cryptocurrencies.
Please visit our Supported Cryptocurrencies help article before sending crypto to Coinbase.
Why can't Coinbase send these funds back to me automatically?
The Ethereum blockchain prevents transfers from being reversed and does not require the receiver to accept the transfer. If the assets were sent from another exchange, this makes it difficult to make sure that the deposit will return to the original sender. For these reasons, we cannot automatically return unsupported ERC20 deposits that are sent to Coinbase.
I sent BEP20 tokens to my Coinbase Ethereum address. How do I recover those funds?
BEP20 tokens have a similar address format as Ethereum and share the same properties of the ERC20 standard, however, they are not the same. BEP20 tokens are on a separate network, which Coinbase currently does not support.
I sent ERC20 tokens on an Ethereum-compatible Layer 2 sidechain to Coinbase. How do I recover those funds?
Assets on Ethereum-compatible Layer 2 sidechains have similar address formats as Ethereum and support similar Ethereum assets, but they are different. For example, Layer 2 sidechains run alongside the Ethereum mainnet but not directly on it, like ERC20 tokens. Coinbase only provides Layer-2 network support and asset recovery for select assets.
At this time, Coinbase can’t recover any unsupported tokens that were previously sent on a supported Layer 2 network or tokens that were sent on an unsupported Layer 2 network. We’re working on a solution to recover tokens sent on unsupported networks and will provide more details here and on the official Coinbase blog when they’re available. Please note that the Coinbase support team can’t manually recover your tokens or provide a timeline on when this solution will be available.
