Fiet Integrates with Reactive Network to Automate Asynchronous DeFi Settlements

Reactive Network

Jan 29, 2026 — 2 min read

Fiet is integrating with Reactive Network to automate one of the hardest problems in DeFi for everyday traders: guaranteeing liquidity is settled promptly without sacrificing user experience.

By deploying Reactive Contracts (RCs), Fiet will remove the need for traders to manually claim funds when liquidity that was temporarily unavailable, becomes available. Instead, settlements will execute automatically the moment liquidity becomes available, delivering a true “set-and-forget” trading experience for on-chain users!

This integration brings decentralized, event-led automation to asynchronous settlement, a core primitive for bridging institutional liquidity into DeFi.

What is Fiet Building?

Fiet is a novel protocol that allows market makers to reuse actively managed off-chain liquidity from banks, exchanges, and brokerages inside on-chain AMMs.

Rather than forcing liquidity to sit idle on-chain, Fiet represents off-chain inventory synthetically. Traders interact with these markets like any other AMM, but settlement happens asynchronously. As traders demand an asset, a market maker delivers the underlying asset, unlocking tighter spreads, deeper liquidity and new revenue streams for professional market makers.However it also introduces a challenge..

The Problem: Manual Settlement Friction

When liquidity is immediately available, settlement is simple. When it isn’t, traders are placed into a settlement queue. This means that a second transaction is required to claim funds, traders are forced to monitor the chain or rely on ad-hoc keepers and the UX degrades during high-volatility periods, when speed matters most. Asynchronous settlement is powerful but without automation, it’s imperfect.

Where Does Reactive Come in?

Reactive Network is purpose-built for on-chain automation. Reactive Contracts can respond directly to events, without off-chain bots, manual interference, or centralized keepers.

For Fiet, this enables:

Automatic monitoring of queued settlements
Instant reaction when liquidity becomes available
Trustless execution of settlement transactions at the right moment
No more manual claiming

Why is This Important?

By integrating Reactive Network, Fiet unlocks several key benefits:

As DeFi pushes toward institutional-grade liquidity, asynchronous settlement is unavoidable. Bridging off-chain capital on-chain requires flexibility but flexibility without automation leads to friction.

This integration shows how Reactive Network can power complex, multi-step DeFi workflows, aggregate state across users and execute precisely when conditions are met.

For Fiet: This turns asynchronous settlement from a UX compromise into a competitive advantage.

For Reactive: It’s a real-world demonstration of advanced automation beyond simple event mirroring - handling queues, aggregation, and batched execution across chains.

As Fiet expands, Reactive automation will be a core part of making off-chain liquidity feel native on-chain. As DeFi evolves, automation moves from a nice-to-have to core infrastructure, and that’s exactly what Fiet and Reactive are building.

About Reactive Network

Reactive is an EVM-compatible execution layer for dApps built with Reactive contracts. These contracts differ from traditional smart contracts by using inversion-of-control for the transaction lifecycle, triggered by data flows across blockchains rather than by direct user input.

Reactive contracts listen for event logs from multiple chains and execute Solidity logic in response. They can determine autonomously when to transmit data to destination chains, enabling conditional cross-chain state changes. The network delivers fast and cost-effective computation via a proprietary parallelized EVM implementation.
