How to Safely Bridge Assets Across Chains

What a bridge does

A cross-chain bridge lets an asset move (or, more precisely, lets a representation of value move) from one blockchain to another — commonly by locking the original asset on its source chain and minting a corresponding wrapped version on the destination chain.

Why bridges carry real, documented risk

A bridge is itself a piece of software, typically holding significant locked value, which has made bridges a frequent and well-documented target for exploits across the industry — bridging carries real technical risk distinct from simply holding an asset on a single chain.

Practical precautions

• Use official, well-established bridges linked directly from a project's own verified documentation, rather than an unfamiliar link.
• Check whether the bridge's contracts have been audited, and review what the audit actually covered.
• Consider bridging smaller test amounts first when using a bridge for the first time.
• Understand that a wrapped asset on the destination chain is only as trustworthy as the bridge that issued it.

What to remember

• Bridges move value between chains, typically by locking an asset and minting a wrapped version elsewhere.
• Bridges have been a frequent, well-documented target for exploits.
• Use official bridges, check for audits, and consider testing with smaller amounts first.
• A wrapped asset carries the issuing bridge's risk as an additional layer.
