Contracts

The source code for each contract is in the contracts/ directory.

Name	Description
price-prediction	Central place managing positions and reward distribution
fast-oracle	Oracle for on-chain data

Build + Optimize Wasm Artifacts

Compiling and optimizing requires these tools to be installed:

• Rust compiler (1.63.0)
• wasm-opt (version 105)

Further if you'd like to compile schemas for the contracts you need to have:

• yarn

If using the nix package manager just run nix-shell to be loaded into an environment with the correct versions of these tools installed.

./optimize.sh

On-chain Blob Verification

You can validate that this source code produced the blob that is powering the on-chain contract. Make sure you have junod and all the dependencies above installed then simply run these two scripts:

./optimize.sh
./validate_onchain_wasm.sh

Testing + Schemas

Contract behavior verified with cw-multitest. Run tests with:

cargo test

Schemas are built using cosmwasm-schema. To build, run:

./build_schema.sh

Schemas will appear in contracts/${c}/schema and TS definitions are written to contracts/${c}/ts.
