Example contracts

Those contracts are made for development purpose only. For more realistic example contracts, see cosmwasm-examples.

Optimized builds

hackatom, reflect and queue are used for testing in other repos, e.g. in go-cosmwasm. staking is used by a demo project in CosmWasm JS (cosmos/cosmjs#170).

To rebuild all contracts as part of a release use the following commands:

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="devcontract_cache_burner",target=/code/contracts/burner/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.9.1 ./contracts/burner

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="devcontract_cache_hackatom",target=/code/contracts/hackatom/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.9.1 ./contracts/hackatom

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="devcontract_cache_queue",target=/code/contracts/queue/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.9.1 ./contracts/queue

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="devcontract_cache_reflect",target=/code/contracts/reflect/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.9.1 ./contracts/reflect

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="devcontract_cache_staking",target=/code/contracts/staking/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer:0.9.1 ./contracts/staking
