Top Layer 3 Projects In 2025

Aragon assists with governance instances, providing infrastructure for Decentralized Autonomous Organizations (DAOs). It simplifies building and managing DAOs. It has also been recognized as reliable by top crypto projects like Decentraland and BadgerDAO.

Chainlink is a prominent project in the Layer 3 crypto list that has marked its territory across the Oracle networks. It aims at bridging the gap between blockchains and off-chain data. It also enables reliable smart contract execution.

Among decentralized domain registrations, Ethereum Name Service (ENS) has marked its stand. It allows the users to name websites, crypto wallets, etc, across different blockchains, with their preferred name and extension. It has so far acquired 500+ integrations.

Filecoin provides a decentralized and permanent data storage system. It utilizes the Interplanetary File Storage (IPFS) system, which enhances data security. It also integrates with Web3 and DeFi protocols. 

Filecoin has become a valuable project, especially in the streaming industries like online video and music streaming.

Flux is a key player among decentralized cloud infrastructures in the Layer 3 space. It is bringing an evolution in the scalability side. It offers a platform where dApps can be developed, managed, and scaled across multiple servers. 

Furthermore, to extend the reach of its services, it has successfully partnered in both traditional and digital domains.

iExec RLC enables the creation of web3 apps without the need for technical expertise. It is like a blockchain marketplace that facilitates custom-developed solutions. It also serves as a platform that supports creativity and innovation.

Ocean Protocol acts as a marketplace for data providers and consumers. It transforms data into an asset that can be traded. It is widely used in digital real estate as well as music streaming, for the purposes it serves. The protocol’s native ERC-20 token is also a good market player.

Quant connects public chains with private chains. It utilizes an Overledger DLT gateway and offers interoperability solutions. Moreover, it extends its support to multi-ledger tokens and multi-DLT smart contracts. Quant has also partnered with Oracle, Hyperledger, and Nvidia for strategic purposes. 

The Graph Protocol, with GraphQL, is a lead player in data indexing. It enables quicker data access, acting as a “Google of blockchains.” This protocol is widely famous for enabling the cross-accessibility of data sets across various domains. This includes DeFi, governance, and social media.

Layer 3 represents the third tier in the hierarchy of blockchain technology. It offers a specialized framework beyond the foundational layers of the blockchain. Layer 1 refers to the primary blockchain, and Layer 2 focuses on scalability improvements. 

Layer 3 solutions extend the capabilities of blockchain by introducing specialized features for a wide range of applications. They address the complex industrial challenges related to privacy, specific app performance needs, and other unique requirements and provide their solutions.
