Building the blockchain

Run

make

This command creates a build directory and in particular, the build/wormchaind binary, which can be used to run and interact with the blockchain.

You can start a local development instance by running

make run

Or equivalently

./build/wormchaind --home build

If you want to reset the blockchain, just run

make clean

Then you can make run again.

Running tests

Golang tests

make test

Client tests, run against the chain. Wormchain must be running via make run or tilt up -- --wormchain

cd ./ts-sdk
npm ci
npm run build
cd ../testing/js
npm ci
npm run test

Interacting with the blockchain

You can interact with the blockchain by using the go binary:

./build/wormchaind tx --from tiltGuardian --home build

Note the flags --from tiltGuardian --home build. These have to be passed in each time you make a transaction (the tiltGuardian account is created in config.yml). Queries don't need the --from flag.

Scaffolding stuff with Ignite

Wormchain was initially scaffolded using the Ignite CLI (formerly Starport). Now, we only use Ignite for generating code from protobuf definitions.

To avoid system compatibility issues, we run Ignite using docker. The below commands should be run using the ignite docker container (see the Makefile recipes for examples).

ignite scaffold type guardian-key key:string --module wormhole --no-message

modify proto/wormhole/guardian_key.proto (string -> bytes)

ignite scaffold message register-account-as-guardian guardian-pubkey:GuardianKey address-bech32:string signature:string --desc "Register a guardian public key with a wormhole chain address." --module wormhole --signer signer

Scaffold a query:

ignite scaffold query latest_guardian_set_index --response LatestGuardianSetIndex --module wormhole

(then modify "wormchain/x/wormhole/types/query.pb.go" to change the response type)
