## What it is
Wormhole is a blockchain interoperability protocol that enables cross-chain messaging and native token transfers across 45+ blockchains. This monorepo contains the reference implementation, including smart contracts, guardian node software, SDKs, and tooling for building multichain applications.

## Use cases
- send verified messages between blockchains
- transfer tokens natively across chains
- build a multichain bridging app in React
- deploy cross-chain messaging contracts on testnets
- run a Wormhole guardian node
- integrate cross-chain swaps into a dapp
- create multichain governance

## When to choose
- you need cross-chain token transfers or messaging in your dapp
- you want to build on or integrate with the Wormhole protocol
- you operate infrastructure for multichain asset movement
- you need a battle-tested interoperability layer with wide chain coverage

## When to avoid
- you only need single-chain smart contract functionality
- you want a simple custodial bridge without protocol complexity
- you cannot accept the risk of bleeding-edge smart contract infrastructure
- you need a lightweight library rather than a full protocol implementation
