Exchange Deposits and Bridges: Check the Route Before Sending

Crypto transfers can look alike in a wallet, but an exchange deposit and a bridge do different jobs: one credits an account, the other moves value between chains. The route determines which network, address and extra details must match.

• Exchange deposit: Send an asset on a network the exchange supports for that deposit.
• Bridge transfer: Move an asset between chains using a bridge’s route and instructions.
• Both: Check the asset, destination and fee before signing or sending.

A bridge can involve smart contracts and other components that lock, mint, burn or release assets, depending on its design. For a fuller look at one route, see this manta bridge explainer. The general point is that a bridge transfer follows bridge-specific steps; it is not an exchange deposit.

How does an exchange deposit work?

An exchange deposit sends funds to an address assigned to your account, and the exchange credits its internal balance after it recognizes the transfer. The deposit page specifies the accepted asset and network; some assets also require a memo or tag to identify the account.

The network must match on both ends. A token with the same name can exist on multiple chains, and an exchange may accept it on only some of them. An address that looks valid does not confirm that the receiving service supports the route.

How does a bridge transfer work?

A bridge moves assets from one blockchain to another through a route designed for those networks. Depending on the bridge, the source asset may be locked or burned, while an equivalent asset is released or created on the destination chain.

The transfer can involve separate network fees, bridge fees and a wait for confirmations or processing. The destination wallet must support the asset on the destination chain. A bridge route and an exchange deposit address are not interchangeable destinations.

What should you check before sending?

Confirm the details shown by the service that will receive the funds. Check what is specified, and treat anything the service does not confirm as unresolved until you verify it directly.

• Match the asset and network to the recipient’s instructions.
• Include a required memo or tag for an exchange deposit.
• For a bridge, confirm the source chain, destination chain and destination address.
• Review fees and the expected route before approving the transaction.

For most readers, an exchange deposit is the direct choice when moving funds into an exchange account on a supported network. Use a bridge when the goal is to move assets between chains, and follow that bridge’s route precisely.
