Cross-chain bridges
Blockchain networks are often isolated and cannot interact with each other directly, so cross-chain bridges serve as a link between them and bring interoperability between different blockchains.
Cross-chain bridges have many use cases, such as enabling decentralized exchanges to support the trading of assets from multiple blockchain networks or allowing users to access decentralized applications (dApps) on different networks. They are also helpful for interoperability between separate blockchain networks, essential for the growth and adoption of blockchain technology.
Available bridges
Regarding bridges, security is the top concern. The Filecoin team is focused on integrating with notary-based bridges that have a solid security model. Eventually, trustless light-client-based bridging solutions will be available.
Axelar enables both token bridge and general message passing and is well-connected to major EVM chains & Cosmos ecosystem.
Initially, the bridge will support the following assets: wFIL, wETH, wBTC, USDC, and USDT.
