The Problem

Trading fiat currencies on-chain today is either too expensive or too risky for liquidity providers. Existing solutions can't provide tight spreads while protecting against exploitation during off-hours when traditional forex markets are closed.

Active Market Making

Concentrated liquidity solutions require constant monitoring and rebalancing - an expensive and complex process that makes passive liquidity provision impractical for most stablecoin issuers.

Oracle Based AMMs

These AMMs use price feeds (like Chainlink) to price trades between fiat stablecoins (e.g., USD/EUR, GBP/EUR, etc). This creates two key problems: spread tied to oracle parameters & value extraction off the market hours.

The Solution

Atlas is a novel AMM implementation optimized for forex trading that delivers tight spreads competitive with traditional markets without requiring active management from LPs. By using a dynamic, algorithm-driven swap fee that respond to oracle and market conditions, this DEX can concentrate liquidity around spot - enabling passive LPs to provide deep, efficient liquidity 24/7.

Technical Roadmap

Algorithm Design – Multiple algorithmic models adjust fees based on:

• Oracle health (staleness, update frequency, deviation thresholds)
• Trade patterns (size, frequency, directional flow)
• Market conditions (on/off hours, volatility)

Rigorous Testing – Historical simulations across market conditions:

• Arbitrage and organic trading scenarios using real forex data
• Performance benchmarking against existing oracle-based AMMs
• Full methodology and results documented in technical paper

Protocol Implementation – Build Atlas using Balancer V3 Hooks:

• Leverage existing infrastructure for AMMs development
• Build minimal UI for liquidity provisioning & trading
• Work with leading aggregators on Atlas integration

Why It Matters

• Tighter spreads: competitive with traditional forex markets
• True 24/7 trading: algorithmic protection during off-hours without prohibitive fees
• Passive liquidity: stablecoin issuers can provide liquidity without active management
• Capital efficiency: deep liquidity around spot enables larger trades with minimal slippage
• Open infrastructure: built on Base, composable with the broader DeFi ecosystem

Atlas enables low-cost, 24/7 trading of fiat-backed stablecoins with spreads competitive with traditional markets—while allowing passive liquidity provision without active management.

How?

Dynamic, algorithm-driven fees that automatically respond to oracle and market conditions. This protects liquidity providers from exploitation while keeping trading costs low, delivering deep liquidity and reliable execution around the clock.

Built on Base using Balancer V3 Hooks, Atlas is fully composable with the broader DeFi ecosystem.

Our primary target customers are:

• Stablecoin issuers & liquidity providers – who need to provide liquidity without constant active management.
• Traders of fiat-backed stablecoins – seeking low-cost, 24/7 trading with tight spreads and reliable execution.

Concentrated Liquidity

These platforms allow liquidity providers to concentrate capital around specific price ranges, but require active management to maintain efficiency. Examples include:

• Uniswap V3 – https://uniswap.org

Oracle-Based AMMs

These AMMs use price feeds (e.g., Chainlink) to price trades between fiat stablecoins, but spreads are tied to oracle parameters and liquidity is less efficient during off-market hours. Examples include:
