What is CosmWasm?

CosmWasm is a Cosmos-native cross-chain smart contract engine based on Wasm, designed from the ground up with a security-first mentality.

Over 60% of IBC-integrated blockchains and over 30 L1 blockchains are using it, and the adoption is accelerating at lightspeed.

It is the only smart contract platform for public blockchains with meaningful, speedy adoption outside the EVM world.


CosmWasm architecture prevents almost all the known risk vectors of Ethereum.


CosmWasm runs the Web Assembly, the Wasm virtual machine guarantees high performance.


CosmWasm was built for a multi-chain, cross-chain world and deeply integrated with IBC (Inter-blockchain communication) from the ground up.

Cosmos is a blue ocean compared to many nascent smart contract platforms.

The future is multi-chain, and most protocols are moving in this direction; CosmWasm is the best tool to give your project wings, if you believe in multi-chain
