Wormhole is a decentralized universal message-passing protocol that enables interoperability between blockchains.
It solves the difficulty of moving tokens between different blockchains and enables communication between decentralized applications (DApps) on different chains.
The most important feature, Wormhole Token Bridge, enables reliable and trustless transfer of crypto assets between layer-one blockchains such as Solana, Ethereum, Binance Smart Chain, Polygon, Terra, Avalanche and Oasis.
Protected by the Guardian Network, Wormhole also supports a wide range of popular blockchains, NFT bridging, and native cross-chain DApps.
After a major hack in 2022, Wormhole backers launched a $10 million bug bounty program to recoup stolen funds and improve security.
