A cross-chain swap is a service or process for exchanging value between different blockchain networks. Because blockchains typically maintain separate ledgers and assets, the swap may use an intermediary, a bridge, or coordinated transactions to convert or transfer value from one chain to another.
These services matter in cyber security because they handle assets and may collect operational data such as transaction details, IP addresses, or session identifiers. Attackers can target swap platforms to steal funds or data, while investigators may analyze transaction records to trace activity across networks. Users and operators should verify service security practices and treat claims about a platform or its data as unconfirmed until independently validated.
