Original: Osmosis RPC: Querying the Cosmos DEX Where the AMM Is a Chain Module
Short summary
Osmosis is the largest Cosmos DEX where the AMM logic lives as native chain modules rather than smart contracts, fundamentally changing how you query it. Developers use three interfaces — Tendermint RPC, LCD/REST, and gRPC — to read poolmanager, gamm, and concentrated liquidity modules directly. Key gotchas include uosmo micro-unit amounts, IBC denom hashes instead of friendly symbols, and instant BFT finality replacing probabilistic EVM finality.
- •Osmosis AMM is native chain modules, not smart contracts — query modules directly
- •Three interfaces: Tendermint RPC, LCD/REST, gRPC for different use cases
- •Watch for uosmo micro-units, IBC denom hashes, and BFT finality differences from EVM
