Built on FastSet, OmniSet unifies fragmented liquidity across chains into a single verifiable layer, enabling instant, bridge-free movement of assets.
Champaign, IL, December 10, 2025 — Pi Squared, the company behind FastSet, the fastest decentralized network for instant payments, today unveiled OmniSet, a universal liquidity and settlement layer designed to connect fragmented liquidity across blockchains into a single verifiable environment.
OmniSet is intended to address one of Web3’s longstanding issues: capital fragmentation across siloed chains, requiring bridges, wrapped assets, and slow or risky transfer flows. Instead of treating each network as a separate liquidity venue, OmniSet works as a minimal, secure building block enabling FastSet to orchestrate multi-chain capital safely.
The problem: Liquidity trapped in islands
While DeFi has expanded across dozens of chains, liquidity has not followed in a unified way. Assets often remain isolated within individual ecosystems, and moving them across chains typically requires bridges that introduce latency, operational overhead, and security risks. Without OmniSet all advanced DeFi users, including VCs, DAOs, whales, and AI agents, have to run their own internal brokering via CEXes, bridges, and thus suffer operational overhead just because they have sophisticated strategies.
Pi Squared positions OmniSet as a shared liquidity and settlement fabric that can orchestrate capital across multiple blockchains, while remaining decentralized, fast, and verifiable through parallel settlement.
What OmniSet does
OmniSet functions as a universal liquidity and settlement layer that sits on top of FastSet. When users deposit assets on a blockchain, OmniSet mints a corresponding representation on FastSet. This representation can be used within applications or withdrawn onto another supported chain, with cryptographic proofs guaranteeing correctness.
Because OmniSet is built on FastSet, it inherits FastSet’s performance profile, including sub-100ms finality, high throughput (150,000+ TPS), and verifiability grounded in Pi Squared’s formal verification background. The architecture allows for scalable, parallelized settlement without requiring bridges or additional trust assumptions.
“OmniSet does for cross-chain liquidity what FastSet does for settlement,” said Grigore Roșu, Founder and CEO of Pi Squared. “It turns a mess of isolated pools into one coherent, verifiable layer. Liquidity becomes portable, execution becomes faster, and the underlying complexity disappears for users and apps.”
How it changes cross-chain liquidity
With OmniSet, chains stop competing as isolated venues for capital and instead plug into a shared liquidity fabric.
That unlocks:
Unified liquidity for DeFi
Protocols can tap into a larger effective pool of assets, regardless of where users originally hold them. Capital no longer has to “choose a chain” to be useful.
Frictionless movement
Deposits, transfers, and withdrawals are orchestrated through FastSet’s parallel settlement, rather than slow bridging flows.
Better UX for humans and agents alike
Traders, protocols, and AI agents can treat multiple chains as a single environment for value movement and settlement.
OmniSet also serves as the foundation for OmniSwap, Pi Squared’s upcoming cross-chain DEX aggregator. OmniSwap will route trades across DEXs and chains while settling through OmniSet’s unified liquidity layer.
Built for the next wave: DeFi, institutions, and agents
Pi Squared sees OmniSet as infrastructure for the next stage of the ecosystem, supporting low-latency liquidity movement for DeFi applications, institutions seeking auditability and clear settlement guarantees, and AI agents executing high-frequency transactions across multiple networks.
About Pi Squared
Pi Squared is delivering on Web3’s promise of instant, trustless payments with its FastSet network. As billions of transactions move to decentralized infrastructure, from stablecoin settlements to AI agentic payments, blockchain architecture simply won’t scale. What’s needed is a new paradigm: verifiable, parallel settlement. Unlike blockchains that rely on total ordering, FastSet settles transactions in parallel, delivering theoretically uncapped throughput, sub-100ms finality, and real-time verifiability.
