We’re delighted to present the Fenix Liquidity Hub, powered by the Orbs’ Layer 3 infrastructure to bring liquidity aggregation to Fenix. This integration will allow Fenix to tap into external liquidity sources to provide even better price quotes across a wider range of assets.

Read on to see why Fenix is the most advanced DEX on Blast.

Solving Liquidity Fragmentation With Intents

Typically, the capacity for a decentralised exchange to provide swaps for traders is limited to the different types of tokens deposited (trading pairs) and the total quantity of those tokens (liquidity). The more liquidity there is, the better the swap rates for traders and a higher number of pairs means better selection for traders.

This poses a clear constraint — a need to maintain high liquidity over the largest number of trading pairs possible. As there are many exchanges offering the same service for traders, liquidity becomes fragmented and poses an intractable problem for DEXs to scale at size to provide the best prices on swaps.

A significantly better trading experience would be a DEX that could bring together multiple sources of liquidity to give traders the best prices on the widest number of assets.

How it works?

The Fenix Liquidity Hub brings together the two of the most efficient trading models in DeFi:

  1. An on-chain solver auction: where third-party solvers compete to fill swaps using on-chain liquidity from AMM pools or their own private inventory.
  2. Decentralised orders via API: A request for quote system, decentralised orders are accessible using API, enabling institutional/professional traders, such as market makers, to submit bids and compete to fill swaps.

Every time a user inputs a trade, The Fenix Liquidity Hub checks if the trade can be executed at a better rate than the internal AMM. If it can’t offer a better price, the trade is executed via our AMM pools. This means that Fenix is always working to provide the best trading experience possible — whichever way the trade goes, Fenix also generates fees from the trade. A win win.

Superior User Experience For Traders

All of this happens behind the scenes within our swap UI. The user simply selects a token from a list of any available asset on Blast and receives a quote. Institutional grade execution doesn’t come at the expense of security and trustlessness. The on-chain contract protects end-users and makes sure funds are secure, and that significant price manipulations cannot occur. All funds remain on-chain, and as always, everything is non-custodial.

Simplicity: A simple swap experience via the Fenix UI — No visible changes

Easy integration: Professional solvers and market makers can easily plug in to the hub to improve prices for traders

Fast execution: Trades have minimal to zero latency allowing users to respond to real-time market movements.

Gasless trades: Users do not need gas to execute trades, reducing the cost of transactions.

Shared Values and Vision

We are delighted to partner with Orbs, an industry leader pioneering Layer 3 technology and contributor to DeFi infrastructure who share our commitment to decentralised applications, community-focus and innovation. Our collaboration reflects our goal to provide high performance DeFi applications.

The Best of DeFi On Blast

The integration of The Fenix Liquidity Hub is a significant step forward for decentralised trading on Blast. By combining Orbs’ Layer 3 infrastructure with the Fenix Unified AMM — Fenix will provide the most advanced trading market for the entire Blast chain.

Fenix and Orbs are setting the standard for what is possible on Blast.
