cw-cyph

A key-value storage smart contract implementation in Rust using CosmWasm. This smart contract allows you to add, delete, and edit key-value pairs using a smart contract in the Cosmos ecosystem.

Usage

This build process assumes you have wasmd and Rust installed on your machine. Instructions on how to set up your wasmd wallets can be found here.

1. Install dependencies:

   rustup default stable

2. In the cw-cyph compile the wasm contract:

   RUSTFLAG='-C link-args=-s' cargo wasm

3. Run unit tests:

   RUST_BACKTRACE=1 cargo unit-test

4. Run the rust-optimizer using docker:

   docker run --rm -v "$(pwd)":/code \
       --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
       --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
       cosmwasm/rust-optimizer:0.12.4

5. Use wasmd to upload te contract:

   RES=$(wasmd tx wasm store artifacts/cw_nameservice.wasm --from wallet $TXFLAG -y --output json)

6. Get the contract code ID and instantiate it:

   CODE_ID=$(echo $RES | jq -r '.logs[0].events[-1].attributes[0].value')
   INIT='{}'
   wasmd tx wasm instantiate $CODE_ID "$INIT" \
   --from wallet --label "cyph password manager" $TXFLAG -y
