Base: What It Is and How Bridging Works
Base uses the same account format as Ethereum, but balances live on separate networks. Moving value between them requires a bridge rather than a normal same-chain transfer.
Key idea
The same-looking address does not mean the asset is on the same chain. Always verify the network before sending or bridging.

An Ethereum wallet can use the same address on Base because both use the EVM account model. The balances and transaction histories on those networks remain separate.
Bridge versus swap
A swap changes one asset into another on a network. A bridge moves value between networks, sometimes with an asset conversion as part of the route.
Confirm the destination
Before approving, check the destination network, recipient and quoted amount. A valid address can exist on several EVM networks while the funds arrive only on the one selected.
