Coinbase: what happens to a deposit on the wrong network

Asset Recovery covers roughly 4,000 unsupported ERC-20 tokens across Ethereum, Polygon, BNB Smart Chain and Base. Recovered assets are delivered to a self-custodial wallet, not to the Coinbase balance — the user needs one to complete the flow. Coinbase states plainly that it cannot recover funds lost by sending on an incorrect network — Asset Recovery covers unsupported ERC-20 style tokens, not wrong-network sends. One exception is documented and worth knowing: when Coinbase later adds support for a network, it has credited qualifying deposits retroactively and automatically (ETH, MATIC or USDC on Polygon; DAI, ETH or WBTC on Optimism), at the original amount rather than the original value. So for a chain Coinbase does not yet support, waiting is occasionally the thing that works. Multi-network support is not available in New York.

Coinbase deposit not showing up — the checks worth doing first

Is this actually your case?

Most missing deposits are not lost — they are waiting on confirmations or sitting in a wallet you can still reach. Paste the hash and find out which.
