The Worldcoin Foundation announced today that World Chain is live for developers. World Chain is a blockchain designed to prioritize human-centric applications and scale with the expansive Worldcoin project.
Developer Preview Now Open
The World Chain developer preview offers an exclusive opportunity for a limited number of developers worldwide to engage with World Chain, which is expected to serve over 10 million users across 160 countries. These users are already utilizing compatible wallets, starting with the World App developed by Tools for Humanity (TFH).
During this preview phase, developers can explore, build, test, and provide feedback on the World Chain. This period will also allow them to set up deployments for the upcoming migration of over 10 million users from the OP Mainnet to World Chain later this summer.
Built on the OP Stack and integrated with the Worldcoin protocol, World Chain is secured by Ethereum as a Layer 2 solution, engineered for scalability within the Superchain ecosystem.
World Chain is backed by key partners such as Alchemy, Safe, and Elliptic
World Chain’s launch is backed by key partners committed to providing top-tier tools and infrastructure. Among these are Alchemy, Safe, and Elliptic.
Thibaut Sahaghian, Head of Network at Safe, mentioned Safe’s commitment to achieving self-custodial ownership for all users through its advanced smart account infrastructure.
“During the World Chain developer preview, developers can use Safe{Core} infrastructure to create exceptional user experiences for millions of verified humans on World Chain,” Thibaut added.
Ryan Wyatt, Chief Growth Officer at Optimism Unlimited, highlighted the significance of Worldcoin leveraging Optimism’s OP Stack.
He noted that the collaboration marks a milestone, enabling Worldcoin’s developers to build ambitious applications and further enhance the Superchain’s impact.
Scalability and Security Focus
Scalability is at the forefront of World Chain’s design. The Worldcoin Foundation has been supporting Optimism and the Superchain, with user transactions on Worldcoin growing to represent approximately 50% of OP Mainnet’s activity.
The new chain aims to address the scalability challenges posed by this rapid growth.
World Chain will initially launch with a standard EIP 1559 fee market, featuring a block gas target set to 10,000,000, doubling the current OP Mainnet capacity. The ultimate goal is to reach 1,000 million gas per second, a 400x increase over the current target, to accommodate the projected growth of the Worldcoin protocol.
World Chain will initially launch with Geth as the sequencer, the standard execution client for OP Stack chains. World Chain will operate Reth, a high-performance Ethereum execution client, in shadow mode during the developer preview to validate the blocks it produces against those generated by Geth.
“We are thrilled to help enable World Chain’s scaling roadmap with Reth,” said Georgios Konstantopoulos, General Partner & CTO, Paradigm. “We look forward to working hand-in-hand with the Worldcoin Foundation, TFH, OP Stack and the rest of the community during the World Chain developer preview to achieve the ambitious mission of breaking through the 1GGas/s barrier and beyond.”
A Human-Centric Blockchain
World Chain aims to be a permissionless, open-source blockchain governed by its users. It will serve as the new base for all World ID integrations, unifying the Worldcoin community. The migration of World App users to World Chain will enable them to send digital dollars globally, explore and swap crypto tokens, and access Worldcoin Grants within eligible regions.
With a focus on providing access to applications that improve lives, World Chain promises to offer innovative use cases in stablecoin finance, international remittances, commerce, and proof of humanness, particularly benefiting users in Europe, Latin America, Asia, and Africa.
Looking Ahead
Developers interested in participating in the World Chain developer preview can apply for access. This preview represents a critical step towards the full launch of a blockchain that prioritizes human needs and scales to meet the demands of a growing global user base.
