Layer raises $6M to make incorruptible foundations of the internet

Three recognized blockchain leaders are coming together to finally bring the underlying trust guarantees of Ethereum to everyday software applications. “Layer SDK” allows developers to write fast, safe, executable code in any language with affordable, built-in decentralization. The trio envisions a digital future where any internet application can be protected against manipulation of all kinds, including dangers posed by malicious AI.

A well-functioning internet is something we get to take for granted, thanks to the built-in security protocols carefully designed underneath. Without them, no data could be securely transferred from place to place at the incredible speed required to support the tech industry’s biggest products.

Today, the existing security protocols are struggling to protect users from even bigger threats, specifically the threats posed by large companies, cyberattackers, and AI that manipulate our online experience and erode trust. Blockchain technologies, like smart contracts, are a real hope to restore trust in the internet. However, smart contracts can only use a small amount of compute, putting limits on what they can support. To build great user experiences on a trustworthy Decentralized Web, we need a way to verify computations outside of blockchains, and make unstoppable applications that, once released, cannot be tampered with.

Recently founded startup Layer aims to extend the functionality of Ethereum by making the first developer tools that support full-stack decentralized applications with Web Assembly.

The company has raised a $6M seed round led by 1kx, with participation from Fabric Ventures, Arrington Capital, Stake Capital Group, and IOBC. Notable angels include Sreeram Kannan of EigenLayer, Rok Kopp and Mike Silagadze of Ether.fi, and Paul Taylor, formerly of BlackRock.

Typically, smart contracts are small programs, specially packaged to be run by trustworthy “validators” on the blockchain. However, to power major software products, like web platforms, smartphone apps, and AI models, smart contracts would need to run thousands of lines of software at speeds you would find on a personal device or datacenter server. While many teams are optimizing the performance of blockchains like Ethereum, smart contracts alone are not capable of meeting the high computational demand of many applications.

Layer utilizes Web Assembly, which allows developers to write applications in languages like rust, that can run anywhere – even on your iPhone. Layer’s upcoming product, the “Layer SDK”, will allow developers to build new layers on top of Ethereum that run full-stack blockchain-based applications consisting of smart contracts, consensus mechanisms, UI, and verifiable off-chain services (AI agents, ZK provers, serverless functions, decentralized messaging servers, and more).

This means, for the first time, a software developer can launch sovereign, incorruptible versions of their software products without any sacrifice to the user experience.

The founders, Sam Cassatt, Jake Hartnell, and Ethan Frey are three of the most seasoned builders in the blockchain space. Their combined experience has been instrumental in the proliferation of blockchain technologies like MetaMask wallets, decentralized autonomous organizations (DAOs), and cross-chain protocols.

By making the decision to band together, the founding team hopes to use all the lessons they have learned in blockchain to fulfill one of its biggest promises – to make all experiences on the internet inherently trustworthy, from the UI down to the functionality, through the shared security mechanisms of smart contracts.

“All three of us have realized that, while smart contracts have given us a foundational layer of trust, they aren’t enough to support a full decentralized version of the Internet,” Sam Cassatt, Co-Founder of Layer explains. “We wanted to complete the full narrative arc of decentralized architecture, and give the world the tools necessary to build any application, with any performance requirements in this trust-minimized way.”

They predict this original ideal, espoused by blockchain’s true believers, will soon be seen as an essential solution to existential threats in our digital world. According to Sam, Jake, and Ethan, the only way to verify the software and data you interact with online has not been manipulated by its creator, its host, a cybercriminal, an AI model, the government, or any other powerful actor would be with a protocol that guarantees trust.

“We are thrilled to back Jake, Sam, and Ethan on their mission to build out the next generation of blockchain infrastructure.” says Wei Dai, Research Partner at 1kx, “Traditional smart contract platforms rely on replicated execution which limits scalability. Layer’s platform and SDK offer the best-in-class scalability, programmability, and configurability for shared-security applications.”

Richard Muirhead, Managing Partner, Fabric Ventures commented: “We at fabric have long been excited to back teams expanding the boundaries of what is possible in crypto and Lay3r are doing exactly that. By defining a new category of shared economic security that spans hybrid off-chain and on-chain worlds, we believe Lay3r can be a Schelling point for new teams looking to build applications taking advantage of these core primitives.” -

The team believes tools like Layer SDK will be the key to mitigating these incredible threats, and make the Decentralized Web the dominant web, complete with all the exciting products the founders have helped to pioneer in blockchain over the last 14 years.
