Unlock the power of composable contracts
CosmWasm provides the DeFi lego experience needed for complex cross-chain applications, with unparalleled security.
Prevents proxy, library conract, and reentrancy attacks
Build, test, and rapidly iterate with Wasm smart contracts.
CosmWasm is a smart contract framework built to make appchain development and maintenance a breeze.
A modern smart contract development workflow
Provides the power and performance of native Cosmos SDK modules with a simpler developer experience
Unit tests, integration tests, and full backtraces are first-class citizens in CosmWasm
Smart contract upgrades are dead simple with CosmWasm's built-in permissioned, per-contract migrate function
Rust language performance and safety guarantees fast and memory-safe dapps
Create a bonding curve
CosmWasm's standard library offers a variety of specific functions and types to build secure DeFi protocols.
CosmWasm has already been used to build many DeFi protocols, like astroport's constant product pool smart contract, which utilizes the compute_swap function in this snippet.
