CosmWasm was originally prototyped by Team Gaians
at the Berlin Hackatom 2019
. In particular, Aaron Craelius
, CTO of Regen Network, designed the architecture with respect to avoiding reentrancy attacks such as those exploited in the now-famous DAO hack, Jehan Tremback
, founder of Althea Network, led the implementation in Rust, and Ethan Frey
, founder of Confio, led the golang piece of the implementation. After the concept was successfully prototyped, the Interchain Foundation
provided a grant to Confio
to implement a production-ready implementation.
