CosmWasm 1.0 code audit started
We released CosmWasm 1.0.0-beta as a version of the software that we consider feature complete but unaudited. The missing code audit is now ongoing.
CosmWasm consists of multiple different software components written in Rust and Go. The audit is broken down into the following scopes of work:
- Scope 1: cosmwasm
This includes the standard library cosmwasm-std which is compiled into the contracts, cosmwasm-vm which hosts contract as well as various utilities for both. Those are packages from the CosmWasm/cosmwasm monorepo written in Rust.
- Scope 2: wasmvm
CosmWasm/wasmvm is the border between the VM implementation in Rust and the Go world that allows the integration in a Cosmos SDK based blockchain. All communication goes through a C interface (FFI). It also translates between garbage collected memory in Go and deterministic memory management in Rust.
- Scope 3: wasmd
The repository CosmWasm/wasmd contains the Cosmos SDK module x/wasm as well as an example standalone blockchain application called wasmd.
Since October 25th the auditing company Oak Security is auditing scope 1. Scope 2 will follow immediately after that. Oak Security has a track record in auditing CosmWasm smart contracts and is familiar with the technology and ecosystem. We expect audit reports for scopes 1 & 2 to be done by Christmas.
Scope 3 will follow by a not yet finalized auditor specialized on Cosmos SDK in Q1 next year.
Bugs and fixes
If bugs come up during the audit, they will be fixed quickly by Confio. We’ll prepare releases and give early notice in case anything critical is on the horizon. We don’t have a process formalized yet, but you can expect careful and responsible behaviour by the maintainers and a process loosely inspired by Cosmos SDK and Tendermint. Following @CosmWasm on Twitter is a good idea in any case.
The wasmvm fix released yesterday as 0.16.2 and 1.0.0-beta2 was not related to the audit.
Confio coordinates the audit as the maintainer of the core CosmWasm components. But we couldn’t have done this without the generous commitments of our CosmWasm 1.0 audit sponsors. Those organizations make clear that if each CosmWasm user commits a bunch of resources and funds, there is a greater CosmWasm freely available to everyone as open source.
