A modular messaging protocol connecting all of crypto
Wormhole Messaging is a decentralized messaging protocol for blockchain developers to securely and easily enable the flow of information and value with other networks. The modular, open source protocol allows developers to tailor the tooling to their chain or app’s needs.
Integrate Easily
Integrate token bridging in just 3 lines of code with Connect, or implement custom cross-chain messaging integrations via the core contracts or the Wormhole SDK.
Accelerate Growth
Accelerate the growth of your users and liquidity by connecting to the leading multi-chain network comprised of 25+ blockchains, thousands of apps, and billions of dollars in value.
Build Securely
Security is held core to the Messaging protocol. The protocol uses signed Verified Action Approvals (VAAs) as a core primitive, Guardian nodes run full nodes for every connected blockchain, and relayers are untrusted in the mechanism.
Maintain Decentralization
Wormhole is the most decentralized cross-chain messaging protocol, operated by a decentralized set of 19 validators called Guardians.
Future-proof your project
As the decentralized computing ecosystem evolves, Wormhole’s modularity allows to update its architecture and messaging mechanisms without breaking integrations.
Scale with time-tested tools
Operating since early 2021, Wormhole was the first-ever generic messaging protocol for blockchains and has strengthened and expanded over time.

Expand your market with simple and flexible integration
Wormhole Messaging provides flexibility in implementation options that work securely across any connected chain and are easy to integrate. Build with an extensible set of verification and relaying options for sending messages between chains and between any of across 6 runtimes including EVM, CosmWasm, and Solana.
Wormhole Guardians are a core element of the Wormhole Messaging protocol. It’s a decentralized network of 19 world-class validators that observe the Core Contract on each supported chain and produce verifiable approvals when those contracts receive a message from the Wormhole Messaging protocol.
Wormhole Messaging also incorporates the Cosmos-native inter-blockchain communication protocol to power verification and transfers within the Cosmos ecosystem, leveraging the Wormhole Gateway appchain. IBC works in tandem with the Guardian network to verify and attest to messages.
Wormhole Messaging also integrates Polkadot's native Cross-Consensus Messaging (XCM) as a verification method through Moonbeam Routed Liquidity (MRL). XCM allows any data or value to be routed from the broader Wormhole network to any parachain on Polkadot in a trust-minimized environment.
Verification
01
Wormhole Messaging sends messages cross-chain using a variety of verification methods to attest to the validity of a message. These options are all available to developers in Wormhole’s platform, depending on the chains involved in a given transaction, and the verification methods will continue to grow over time to incorporate new technologies.
Relaying
02
Wormhole Messaging leverages heterogeneous relaying processes that enable a verified message to be sent to its intended destination. Relaying can be done in two different ways, with Automatic Relaying being the easiest path for most teams.

#1Rated Cross-Chain Messaging Protocol
by Uniswap’s Bridge Assessment Committee’s security experts
Wormhole received the top rating after Uniswap’s multi-month deep technical analysis of six messaging protocols. The assessment framework consisted of 20 subcategories and over 130 assessment questions covering topics like security, decentralization, technical architecture, implementation risk, and operational risk. Wormhole was the only protocol approved without conditions for use in all cross-chain deployments by Uniswap’s Committee.
