How to add a new chain or contract

1. Add the chain information to contract manager CosmWasmChains.yaml. You can lookup for rpc endpoints in this repo. The gasPrice is the average_gas_price of the chain + the chain token denom (Available in chain-registry chain.json file).

2. If the wormhole contract is not deployed on the target chain run the following command:

   pnpm instantiate-wormhole -- --private-key <YOUR_PRIVATE_KEY_HEX> --deploy <stable or edge> --chain <chain>
   

You can re-build the wormhole contract using the scripts given in wormhole-stub. Run build.sh and you will get the compiled contract code in wormhole-stub/artifacts

1. Deploy the pyth contract:

   pnpm instantiate-pyth --contract-version <X.Y.Z> --private-key <YOUR_PRIVATE_KEY_HEX> \
      --deploy <stable or edge> --wormhole <WORMHOLE_CONTRACT_ADDRESS> --chain <chain>
   

2. You can test the new contract via contract manager scripts like this:

   cd ../../../contract_manager
   pnpm exec ts-node scripts/update_pricefeed.ts --private-key <YOUR_PRIVATE_KEY_HEX> --contract <CONTRACT_ID> --feed-id <FEED_ID>
   

3. Commit the new entries added to contract manager yaml files

4. Update documentation repos and add the new contract address
