What is deposit address?

The address an exchange issues for you to receive one specific asset on one specific network.

Send only the named asset on the named network. Anything else is usually unrecoverable, and the reason is that the address is meaningful only in the context the exchange assigned it. Some assets also need a memo destination tag, and some exchanges issue a fresh address for every deposit.

The mistake that dominates support queues is treating an address as belonging to a coin. It belongs to a network. The same address string can exist on several Ethereum-compatible chains, and the exchange controls it on only the ones it operates.

How it works

An exchange holds customer assets pooled in a small number of wallets rather than one per customer. A deposit address is a marker that tells its systems which internal balance to credit when funds arrive, and behind the scenes those funds are usually swept into the pool afterwards.

There are two ways exchanges do this and the difference matters:

Unique address per customer. Each user gets their own address per asset and network. Sending to it credits your account with no extra step, and reusing it for later deposits is normally fine.

Shared address plus a tag. Chains such as XRP, Stellar, Cosmos and several others use one exchange-wide address for everyone, with a numeric memo or destination tag identifying you. Omit the tag and the funds arrive at the exchange but with nothing to say whose they are, which requires a manual recovery process that some venues charge for and some do not offer.

Deposits credit after the exchange's required number of confirmations, which is its own policy rather than a network rule.

Addresses can be rotated. An exchange may issue a new address and stop monitoring an old one, which is why a saved address from a year ago is worth re-checking rather than reusing on trust.

Example

Illustrative. You withdraw USDC from one exchange to another. The receiving exchange lists three USDC deposit addresses, one per network. You copy the address for one network but select a cheaper network in the sending exchange's withdrawal form. The transaction confirms in seconds and costs almost nothing. The receiving exchange never credits it, because it does not operate on that network, and the address there is controlled by nobody. Recovery depends entirely on whether the receiving exchange offers a manual retrieval service for that chain.

Why it matters when you buy

Every transfer between venues, and every withdrawal to your own wallet, runs through this. Sending a small test amount first costs one extra network fee and confirms both the address and the network before the full amount moves. The chain pages show which networks each asset runs on, and move crypto off an exchange walks through the process.

Questions

Can I reuse a deposit address?

At most exchanges yes, though some rotate addresses and a few explicitly ask you to generate a fresh one each time. Check the current address in the deposit screen rather than reusing a saved one from months ago.

What if I forget the memo or tag?

The funds reach the exchange but cannot be attributed to your account. Most venues have a recovery process, often requiring identity verification and sometimes a fee, and some will not recover small amounts at all.

What happens if I send the wrong asset?

If the exchange supports that asset on that network, it may still credit it or offer manual recovery. If it does not, the funds sit at an address on a chain where the exchange holds no key, and they are generally lost.
