Quick answer: If coins, tokens or NFTs appear missing after moving to the new Base app experience, the assets may still exist in your wallet. Coinbase explains that Base mode and Legacy mode show different experiences, and assets on unsupported networks may remain available through Legacy mode even when they are not visible in Base mode.

Why can assets disappear from the Base app view?

The Base app evolved from Coinbase Wallet and now includes a Base mode powered by smart-contract wallet functionality. Coinbase says existing wallet assets remain accessible, but unsupported assets are not necessarily displayed in the new Base mode.

This is a visibility and network-support issue, not proof that the blockchain assets were transferred away.

First: verify the assets on-chain

Before changing wallet settings, find your public wallet address and check it with the correct blockchain explorer. If the token balance or NFT is still associated with your address, the asset has not disappeared from the blockchain simply because the app interface does not display it.

Never paste your recovery phrase into a block explorer. Public addresses are enough for balance checks.

Switch between Base mode and Legacy mode

Coinbase says users with an existing wallet can open the profile sidebar and use the Base mode switcher. Turning Base mode off returns to the Legacy experience. Assets unsupported in Base mode may still be available there.

If you upgraded the wallet for Base mode, Coinbase says the upgrade enables new smart-account features without requiring you to transfer all existing digital assets to a new wallet.

What about unsupported networks?

Coinbase has also warned that some networks are no longer supported in the Base app, including Dogecoin, Litecoin and zkSync Era. The company says assets on unsupported networks remain safe and accessible, but users may need another compatible wallet to interact with them.

If importing into another wallet is necessary, use software from the wallet provider's verified source. A recovery phrase controls the wallet; entering it into a malicious app can expose every asset derived from that phrase.

What if the address changed?

Compare the public address shown in the app with the address that actually holds the asset. If they differ, confirm that you are viewing the correct account or wallet profile. Do not send funds between addresses until you understand which account controls each address.

Do not use “wallet recovery” websites

Scammers target users who believe assets disappeared after an app update. There is no legitimate need to “synchronize” a wallet by typing a seed phrase into a website. Do not respond to unsolicited support DMs, remote-access requests or links promising to reveal hidden balances.

FAQ

Are missing assets necessarily lost?

No. First verify the public address on the correct blockchain explorer.

Can I return to the old wallet experience?

Coinbase says existing-wallet users can switch Base mode off to use the Legacy experience.

Why are unsupported assets not visible?

The Base app does not provide the same network support in Base mode. Unsupported assets can require Legacy mode or another compatible wallet.

Should I import my recovery phrase somewhere else?

Only if Coinbase's guidance requires another compatible wallet for an unsupported network, and only after independently verifying the wallet software. Never enter the phrase into a support website or share it with a person.
