Wormhole is the leading interoperability platform powering multichain applications and bridges at scale. The platform is designed to connect different blockchains, allowing for the secure and efficient transfer of data and assets. Individual blockchains like Ethereum and Solana are not inherently compatible with each other. Imagine Wormhole as a series of highways connecting cities, where each city represents a distinct blockchain ecosystem.
In 2020, Wormhole introduced the first-ever general messaging protocol, with the original goal of connecting Ethereum and Solana. At the time, Wormhole was the only way to transfer assets between Ethereum and Solana at scale. By facilitating interoperability between the two chains, Wormhole played a key role in growing the Solana ecosystem — even co-hosting the first-ever Solana Hackathon in October 2020, called the Solana Wormhole hackathon.
Since those early days of connecting Solana and Ethereum in 2020, Wormhole has become the leading interoperability platform. Wormhole's modular suite of open source, permissionless protocols and tools are being used by the multichain builders of over 200 applications and more than 1 million unique wallets to move various types of data across 30+ blockchains. The platform has handled over 1 billion multichain messages for applications and is trusted by teams like AMD, Uniswap, Circle, Lido, Synthetix, Pyth, Pancakeswap, Jupiter, Backpack, and more. In 2023, the Uniswap Foundation’s Bridge Assessment Committee conducted a third-party multi-month study that resulted in a report showing Wormhole rated #1 and the only unconditionally approved interoperability protocol for use by the Uniswap DAO, a study based primarily on security and decentralization practices.
The Wormhole platform is being developed by a decentralized set of teams that contribute to security, engineering, research, product development, ecosystem growth, and community. These teams include Wormhole Foundation, xLabs, Wormhole Labs, and Asymmetric Research, as well as other contributors like Wormhole China, Superteam, ZK engineering teams like Lurk, Zpoken, and Succinct, among others.
In the traditional blockchain development paradigm, applications are often confined to their native ecosystems, limiting their functionality and interaction capabilities. Wormhole breaks down these boundaries, offering developers a solution for creating applications that operate seamlessly across multiple blockchains. These solutions are primarily facilitated by Wormhole's foundational Messaging protocol, which allows for the secure transfer of arbitrary data between blockchains.
Wormhole prioritizes the safety and integrity of cross-chain communications and multichain development by leveraging proven technology and decentralized validation via the Guardians, a decentralized network of 19 validator nodes that ensures message integrity and security. Every aspect of Wormhole is fully open source and can be viewed in the Wormhole Foundation Github. Anyone interested in seeing a visual representation of multichain activity being enabled by Wormhole is encouraged to visit Wormholescan.
Wormhole is committed to building a future-proof, decentralized ecosystem. Its mission extends to enhancing the multichain developer experience through improved software development kits (SDKs), tooling, and documentation, alongside pioneering new messaging pathways with zero-knowledge (ZK) proofs for trustless authentication. Introducing the Wormhole token (W) has further decentralizes governance and enhances utility, marking a new chapter in Wormhole's journey as it continues to lead at the forefront of Web3's infrastructure.
Scroll is an Ethereum Layer 2 (L2) aiming to offer a secure, low-cost, developer-friendly execution layer with maximum EVM equivalence. This will allow anyone, anywhere, to build decentralized apps on-chain and will enable a seamless migration to L2 for any Ethereum-based application.
Scroll aims to be decentralized and permissionless, open to anyone with the vision of building scalable applications within Ethereum security guarantees. It is a validity rollup, which processes transactions off-chain, subsequently posting data to Ethereum L1 and verifying state by posting Zero Knowledge Proofs (Halo2) to L1, which are verified in a smart contract.
Scroll's technical architecture includes:
Scroll Node & Sequencer: Creates L2 blocks (orders transactions), and commits data to Ethereum L1, alongside a Halo2 proof.
Roller Network: Generates Halo2 validity (ZK) proofs of the EVM execution, making Scroll become what is commonly referred to, as a “zkEVM”.
Rollup and Bridge: L1 Contracts that handle proof verification on Ethereum and enables communication with L1 (e.g. for token transfers.)
Scroll plans to decentralize its sequencer and Roller roles in the future, bolstering security & liveness guarantees through improved network decentralization.
By leveraging the verifiable computation of its zkEVM, Scroll scales EVM-equivalent execution to thousands of TPS, while maintaining L1 security. Given the low friction to Ethereum L1, Scroll has already been gaining quite significant traction.
If you’re interested in building a multichain application that encompasses Scroll, or simply want to transfer tokens to or from Scroll, you can easily do so using Wormhole.
If you have assets on any of Wormhole’s 30+ connected blockchains and want to bridge to or from Scroll, you can do so via Portal Bridge by following the below steps:
Head to Portal Bridge
Connect your Wallet
Select Scroll as either the Source or Target chain for your transaction
Complete the tarnsfer process
If you are a builder who wants to enable token transfers to and from Scroll, you can do so in just three lines of code via Wormhole Connect. Connect enables developers to bring wrapped and native token transfers directly into their application UIs and can seamlessly enable bridging to and from all of Wormhole’s 30+ connected blockchains, not just Scroll, and secured by the Wormhole Guardians.
To start integrating Connect and enabling your application on Scroll, check out the NPM package to get started.
