Alephium Bridge
The Alephium Bridge is a sophisticated system with various components that work together to achieve efficient cross-chain communication. It is what’s called a lock & mint bridge, built on top of a fork of Wormhole.
It enables the bridging of assets from Ethereum to Alephium (and vice-versa). On Alephium, you can use these assets on several apps like DEXes or NFTs marketplaces.
