ATOM Intent-Based Liquidity System

An intent-based trading system for Cosmos Hub that achieves:

• 2-5 second execution (vs 6-30s traditional)
• Near-zero solver capital (vs $500k+ traditional market makers)
• CEX-competitive pricing (within 0.1-0.5% of Binance)
• Robust IBC infrastructure (solver-incentivized relayers)

Core Innovations

Problem	Traditional Solution	Our Solution
Liquidity provision	Pre-positioned inventory ($500k+)	JIT solver execution (zero capital)
Cross-chain settlement	Manual multi-step bridging	Atomic IBC with wasm hooks
Relayer reliability	Altruistic public relayers	Solver-integrated relayers
Price discovery	Fragmented DEX liquidity	Intent matching + aggregation
Partial fills	Rare/unsupported	Native throughout

Liquidity Source Hierarchy

1. Intent Matching (zero capital) - Direct crossing of opposing user orders
2. DEX Routing (zero capital) - Aggregating existing Cosmos AMM pools
3. CEX Backstop (~$50k buffer) - Minimal inventory hedging against CEXes
