Bridges
A bridge locks or burns assets on one chain and mints or releases a representation on another. The asset you receive can be a claim on the original, not the original coin itself. That claim is only as good as the bridge contracts and the people or proofs behind them.
What can go wrong
Contract bugs can mint extra claims or trap the locked assets. A wrong or fake interface can send the transaction to a copy of the bridge. Wrapping means the token on the destination chain is a different contract from the token you started with, even when the ticker looks the same.
The official PulseChain bridge
The official PulseChain bridge moves value between Ethereum and PulseChain. Other ecosystems publish their own official bridges. A bridge from a random site that uses the PulseChain name is not this one. Chapter 4 explains why a layer 2 bridge is a different hop from this Ethereum-to-PulseChain bridge. Chapter 8 is the list of swap venues that stay on their own chains.
What Liberty Swap publishes
Liberty Swap describes its product as intent-based swapping and bridging. The docs and the site advertise a zero-fee PulseChain decentralized exchange, and in-wallet swap and bridge through ZKX. When that flow is turned on, you move among the chains they support from ZKX, without a separate website. That is their published product. It is not a promise that every chain is included, and it is not a promise of zero fees on every route.
