Modular Blockchains Transform Web3 Infrastructure With New Projects

Modular blockchains are transforming Web3 infrastructure by separating core functions such as execution, consensus, and data availability. This separation enables the creation of faster, more scalable, and customizable networks. While established projects like Celestia and EigenLayer are at the forefront, a new wave of lesser-known projects with significant potential is emerging. These modular blockchain tokens, with market caps under $5 million, present an opportunity to invest early in the next generation of crypto infrastructure. Here are five projects worth monitoring closely.

KardiaChain ($KAI) is a Layer-1 blockchain designed to bridge the gap between blockchain technology and mainstream adoption. As a hybrid public-private blockchain infrastructure, KardiaChain focuses on decentralization, security, and scalability to deliver seamless Web3 solutions for real-world applications. It powers transformative technologies like Onchain AI and NF3 Chip Technology, further expanding its ecosystem. The KAI 2.0 network upgrade is currently underway, with stakers on KAI.now automatically upgraded and restaked on the new network. Non-stakers need to take a few steps in the KAI X handle. The all-time high for KAI was recorded on April 14, 2021, at a price unit of $0.1596, while the all-time low was recorded on January 30, 2025, with a price unit of $0.0001404. KAI is listed on exchanges such as Gate and Coinex.

Matchain ($MAT) is the native utility and governance token of Matchain, an AI-integrated, zk-rollup Layer 2 blockchain. It is designed for real-world business adoption, decentralized advertising infrastructure, and intelligent content engagement. MAT powers every layer of the Matchain ecosystem, from governance and staking to AI-enhanced marketing tools and decentralized identity systems. The all-time high for MAT was recorded on June 19, 2025, at a price unit of $6.67, while the all-time low was recorded on June 26, 2025, with a price unit of $0.4231. MAT is listed on exchanges such as Bitget, MexC, Gate, Kucoin, Kraken, and Bitmart.

Lumerin ($LMR) is an open-source protocol and foundational layer that uses smart contracts to control how P2P data streams are accessed, routed, and transacted. It is currently being leveraged to decentralize and more efficiently allocate AI compute power, enabling novel applications on DePIN and tokenization of RWAs. Lumerin can also enable encrypted video and audio streams, permissioned communications, and programmable data streams and digital assets like NFTs. The all-time high for LMR was recorded on March 29, 2022, at a price unit of $0.3344, while the all-time low was recorded on March 27, 2025, with a price unit of $0.002252. LMR is listed on the Gate exchange.

SatoshiVM ($SAVM) is a decentralized Bitcoin ZK Rollup Layer 2 solution compatible with the Ethereum Virtual Machine (EVM) ecosystem, using native BTC as gas. SatoshiVM bridges the EVM ecosystem with Bitcoin, enabling the Bitcoin ecosystem to issue assets and develop applications. The all-time high for SAVM was recorded on January 19, 2024, at a price unit of $14.88, while the all-time low was recorded on April 7, 2025, with a price unit of $0.1128. SAVM is listed on exchanges such as MexC and Gate.

Idena ($IDNA) is a novel way to formalize people on the blockchain without personally identifiable information. Idena proves the humanness and uniqueness of its participants by running an AI-resistant test simultaneously for everyone around the globe. The Idena blockchain is driven by Proof-of-Person (PoP) consensus, where every node is linked to a cryptoidentity—one single person with equal voting power. Idena’s network of validated people solves the blockchain oracle problem, as its independent mining nodes can act as oracles. The all-time high for IDNA was recorded on August 31, 2020, at a price unit of $0.3169, while the all-time low was recorded on May 12, 2025, with a price unit of $0.001423. IDNA is listed on the Bitmart exchange.

These five modular blockchain tokens, with market caps under $5 million, offer a unique opportunity to invest early in the next generation of crypto infrastructure. Each project brings innovative solutions to the table, addressing various aspects of blockchain technology and its real-world applications. As the crypto landscape continues to evolve, these under-the-radar projects could emerge as significant players in the modular blockchain space.
