Issue Once. Use Everywhere.

With Fusion’s multi-ledger rollup, institutions can now issue truly interoperable assets native across multiple blockchains. A stablecoin or tokenised fiat asset no longer needs to be minted, burned, or wrapped just to function across different layer 1 networks.

Instead of handling separate token representations across Ethereum, Polygon, Solana, and others, Fusion merges them into a single, unified multi-ledger asset. This creates a new unified liquidity layer, removing fragmentation and enabling seamless cross-chain utility.

And this capability isn’t just limited to institutions. Any asset, whether issued by a project, protocol, or developer, can now go multi-chain.

Explore the latest Fusion Devnet implementation, with Testnet and Mainnet on the horizon:

🌐 What Are Multi-Ledger Rollups?

Traditional rollups scale single chains, creating silos and walled gardens.
Multi-Ledger Rollups (MLRs) scale multiple chains at once.

They enable cross-chain smart contracts to execute in a single flow, maintaining interoperability and consistency across public and permissioned blockchains.

Scalable. Interoperable. Compliant.

🔧 Quant Fusion Devnet Update – 4 July 2025
We’ve officially launched the Fusion devnet and reached several key milestones in our journey toward secure, interoperable, enterprise-grade blockchain infrastructure.

Here’s what’s happened so far:
•Deployed implementation contracts to Ethereum Sepolia, Polygon Amoy & Avalanche Fuji
•Began transaction testing using Foundry, including with upgradeable proxy contracts
•Initiated smart decisions around transparency, upgradeability, and mainnet/testnet strategy
•Tested sequencer APIs & ETH JSON-RPC integration — ✅ passed
•Deployed our chosen DEX (announcement coming)
•Progressed our open source spec to support scalable, multi-network connectivity

This is a crucial step forward and we’re gathering feedback throughout devnet as we shape the move to public testnet and beyond.

🔄 Eliminating Wrapped Tokens

Say goodbye to the complexities of wrapped tokens. With Multi-Ledger Rollups, assets from different blockchains can interact directly, simplifying liquidity pools and reducing risks with legacy layer 1 bridges.

What is the Trusted Node Program?

Overledger Fusion is powered by a flexible and incentivised network of trusted node operators fit for institutional use. Key features include:

- Decentralised control: Approved node operators determine which underlying blockchains to host.
Flexible onboarding: Onboard new ledgers with ease via Bring Your Own Node and Bring Your Own Connector capabilities.

- Granular access control: Define organisational and cross-organisational permissions using customisable API key roles and gateway rules.

- Incentivised participation: Approved node operators of the Layer 2.5 network can determine the underlying blockchains to host to expand the reach of the Layer 2.5 network. Leveraging our previous thinking and experiments in remote connector gateways from 2021, as well as rewards in QNT, node operators can stake QNT for transaction priority from the transactions their nodes process.

Anyone can participate. Users who are currently an https://t.co/h3EubTTjI2 KYC'ed user can participate in the TNP. Of course, enterprise and institutional customers are also invited to participate!

The goal is to expand the Layer 2.5 to interconnect and interoperate as many permissioned and permissionless blockchains as possible.

What is the Layer 2.5 Network?

Layer 2.5 is a next-generation interoperability layer that bridges the gap between layer 2 scalability and layer 1 decentralisation without compromise. It introduces a unified ledger network architecture designed for institutional, enterprise, and DeFi ecosystems with the following core capabilities:

🔹 Multi-Chain Rollup Architecture
Not limited to a single layer 1 or a current single-chain layer 2 rollup. Layer 2.5 aggregates and scales across multiple blockchains, enabling true multi-chain ubiquity and distribution of assets and transactions.

🔹 Trusted Node Program
Confidence is built in. Approved node operators uphold security and extend network reach, ensuring trust and reliability at scale for institutional adoption.

🔹 Built-In Privacy and Advanced Security
Assets, smart contracts, and transactions are protected with embedded privacy features and enterprise-security controls by default.

🔹 True Any-to-Any Interoperability
By operating above layer 1s, Layer 2.5 eliminates the need for insecure or inefficient 1:1 bridges, enabling seamless, scalable interoperability between any network.

🔹 Enterprise-Grade Connectivity
Extend private, permissioned DLTs and tokenised assets into public blockchain ecosystems without sacrificing control, compliance, or confidentiality.

🔹 Performance at Scale
Layer 2.5 accelerates transaction throughput, dramatically reduces gas fees, and scales efficiently across interconnected networks.
