In a move that could significantly enhance cross-chain identity verification, Wormhole, the popular cross-chain interoperability protocol, has been awarded a grant by the Worldcoin Foundation to integrate World ID onto the Solana blockchain.

World ID is a decentralized identity protocol designed to enable users to prove their humanness online while maintaining privacy. This integration aims to make it seamless for Solana-based protocols to verify users' World IDs originally authenticated on Ethereum, showcasing the flexibility of Wormhole's multi-chain infrastructure.

How It Works

The integration will leverage Wormhole's Ethereum to Solana State Bridge Service to ensure that the verification functions for World ID are enabled on the Solana blockchain without compromising security or performance. A new smart contract, SolanaWorldIDProgram, will be introduced to validate and store World ID state roots. This will allow Solana-based applications to easily authenticate users' identities, potentially opening up new possibilities for developers in the Solana ecosystem.

Implications for Web3

This integration is a significant step forward for Web3, as it strengthens security, decentralization, and cross-chain interoperability. By making it easier for users to verify their identities across different blockchains, the integration promotes a more inclusive and secure digital economy.

Additional Developments

In response to recent regulatory concerns, Worldcoin has also introduced enhanced privacy measures. These include the use of zero-knowledge proofs (ZKPs) to minimize the amount of personal data that needs to be shared for verification.

Market Reactions

The news of this integration has been met with positive reactions in the crypto market. The price of Worldcoin's WLD token has surged since the announcement, while Solana's native token, SOL, has also seen a significant price increase.


The integration of Worldcoin's World ID with Solana through Wormhole is a testament to the growing maturity of the Web3 ecosystem. It demonstrates the potential of cross-chain solutions to address critical challenges like identity verification and privacy, paving the way for a more user-friendly and secure decentralized internet.
