Bridges explained: moving between networks adds a dependency

The idea in plain English

A bridge coordinates value or messages across separate networks. Depending on its design, it may lock one asset and issue a representation, release liquidity on the other side or use a different transfer mechanism. The output may not be the same native asset you started with. Read the specific design.

The distinction that matters

A bridge adds components to trust: contracts, validators or operators, proof mechanisms, liquidity and possibly upgrade permissions. Security of the source and destination chains does not automatically secure the bridge between them. Fees, delays and an exit route should be understood before use.

A practical example

An illustrative bridge locks a token on Network A and issues a representation on Network B. If the mechanism securing the locked asset fails, the representation may not be redeemable even though Network B continues producing blocks normally.

Try this without moving money

• Draw what is locked, issued or released on each side.
• Identify the output token and its redemption path.
• List bridge-specific failure modes separately from network risks.

A mistake to avoid

Do not bridge only to chase a promotional yield without understanding how to get back. A cheap entry can conceal an expensive or unavailable exit.

Before you act

Matching an address format is not enough. The receiving service must support the exact asset and network, and any required memo or tag. Fees, minimum deposits and confirmation policies can change. The practice exercises here are simulations: they neither validate a real address nor send a transaction.
