Wormhole Protocol is a non-custodial cross-chain messaging protocol that enables fast transfers of cryptocurrency, NFTs, and arbitrary payloads across over 30 major blockchain networks, including Polygon, Cosmos, and more.

Its core is built on a group of independent nodes, requiring a supermajority to validate and sign each transaction. This enables decentralized validation.

The protocol is fully open-source, with security audits conducted by top firms like Neodyme. A substantial bug bounty program encourages vulnerability disclosure.

Developers benefit from generic message support, which enables use cases like cross-chain governance. Its SDK and tooling make building cross-chain Wormhole Bridge .

Wormhole’s Token Bridge supports ERC-20, SPL tokens using a wrapped asset model with full payload preservation.

Use cases include:
- Cross-chain DeFi
- Multichain NFT transfers
- DAO governance messaging
- Data-driven dApps

Despite a major exploit in 2022 involving $326M, Wormhole has since upgraded its auditing frequency and remains a leading protocol in the Web3 space.

Whether you're a developer, Wormhole provides the infrastructure to power multi-chain innovation with speed.
