Quant Network has officially launched the Fusion Rollup mainnet, a milestone that coincides with the tenth anniversary of the company’s founding by Gilbert Verdian. The company described the launch as a major advancement in blockchain interoperability, introducing what Verdian characterized as the first multi-ledger rollup deployed in a production environment.
The newly launched system is designed to connect 74 blockchain networks within a single execution environment, addressing a longstanding challenge faced by financial institutions that operate across multiple distributed ledger ecosystems. Quant stated that the platform is intended for banks, asset managers, and enterprises seeking seamless interaction across numerous blockchain networks. The rollout also includes the Trusted Node Program, which enables organizations to integrate additional networks as their requirements evolve.
Multi-Ledger Architecture Eliminates Traditional Barriers
Fusion Rollup introduces a multi-ledger framework that connects 74 blockchain networks within a single execution environment, allowing institutions to transact across chains without relying on bridges or wrapped tokens.
Quant explained that Fusion occupies a position between underlying blockchains and application layers, a structure the company refers to as Layer 2.5. Unlike conventional rollups that depend on a single Layer 1 blockchain, Fusion operates across multiple ledgers simultaneously. The system utilizes an optimistic rollup architecture derived from the OP Stack while storing transaction data on a permissioned Hyperledger Besu network.
State roots are transmitted back to connected Layer 1 networks, allowing institutions to move assets, settle transactions, and exchange messages across different blockchains through a unified framework. By removing the need for blockchain bridges and wrapped assets, the platform aims to reduce security risks that have historically contributed to significant losses within the digital asset sector.
Unified Asset Model Addresses Liquidity Fragmentation
A central feature of Fusion is its unified asset model, which seeks to solve the problem of fragmented liquidity across multiple blockchain ecosystems. Quant noted that digital assets such as USDC currently exist as separate versions on numerous networks, including Ethereum, Solana, Polygon, Avalanche, Arbitrum, Base, and BNB Chain.
Today we go live on mainnet with the Fusion Rollup, the world's first multi-ledger rollup, connecting 74 blockchain networks in one unified environment, built for institutions.

Under Fusion, these separate representations can be consolidated into a single canonical asset referred to as uUSDC. Similarly, tokenized assets such as BlackRock’s BUIDL fund can be represented as unified instruments within the rollup environment.
The platform’s unified asset model consolidates fragmented versions of digital assets into single canonical instruments, providing institutions with one liquidity pool, one compliance framework, and a unified balance-sheet view across connected networks.
Fusion is the world's first multi-ledger rollup, we call it Layer 2.5 because where a conventional Layer 2 anchors to a single Layer 1, Fusion anchors to N L1s simultaneously. https://t.co/XavBmaOICQ#QuantFusion #MultiLedgerRollup pic.twitter.com/xVZEmNZfpB

According to the company, each asset remains linked to its native blockchain while preserving the ability to be withdrawn at any time, ensuring interoperability without sacrificing underlying chain integrity.
Broad Blockchain and Institutional Connectivity
While Quant has not disclosed the complete list of all 74 connected networks, company materials indicate support for several major public blockchains, including Ethereum, Bitcoin, Solana, Polygon, Avalanche, Arbitrum, Base, BNB Chain, XRP Ledger, Stellar, and XDC. The platform also supports permissioned networks such as Hyperledger Fabric, R3 Corda, and various private enterprise EVM environments.
Horizontal scalability. Fusion scales by connecting additional #networks rather than by adding nodes to a single chain.
The platform is already live with over 73 connected networks and 1,000+ nodes, and new Layer 1s can be onboarded without re-architecting the rollup or…

Fusion additionally connects with central bank digital currency testing initiatives that Quant has previously supported, including projects associated with the Bank of England, the European Central Bank, and the Bundesbank. Through the Trusted Node Program, enterprises can further expand network connectivity using bring-your-own-node and connector capabilities.
Compliance and Institutional Adoption Strategy
Quant enters this phase with established relationships across the financial sector. Over recent years, the company has participated in projects involving central banks, tokenization initiatives, and enterprise blockchain deployments. Partnerships with organizations such as Oracle, UST, and risk-management provider Murex have helped position the company within institutional digital asset infrastructure.
Fusion incorporates protocol-level compliance controls, including role-based permissions, KYC enforcement, governance mechanisms, and interoperability standards, enabling institutions to meet regulatory requirements while operating across multiple blockchain networks.
The platform also integrates Overledger Firewalls and leverages ISO 82098 standards for cross-ledger messaging. Meanwhile, the QNT token serves as the foundation for network access, staking, transaction processing, and institutional licensing functions.
As institutional tokenization and real-world asset adoption continue to expand in 2026, Quant believes Fusion offers a solution to one of the industry’s most persistent challenges: asset fragmentation. The company now awaits broader institutional deployment as banks and asset managers evaluate the platform for live production use.
