AudiusData <-> Anchor

Overview:

Implementation of audius data layer in Anchor (Solana framework)

./cli/
    - CLI to interact with deployed instance of AudiusData, has helpers as well for reuse in shared libs layer

./lib/
    - Typescript bindings for program interaction, shared with programs/tests and cli/
    - Utils typescript located here as well

./programs/
    src/
        - Program source code deployed to blockchain
        - Single file, lib.rs

    tests/
        - Unit tests to validate program functionality

---

Developing:

1. Provision a fresh dev environment (ubuntu)
2. Install dependencies:

npm run install-dev

3. In one terminal, run test validator:

solana-test-validator

Deploying:

• Build:

npm run build-dev

• Provision localnet in one shell:

npm run localnet-up

• In another shell, deploy:

npm run deploy-dev

• kill your test validator and run tests to confirm IDL:

npm run localnet-down && npm test

Note that if you get error logs during tests but tests still pass, you can ignore the logs.

Sending transactions:

As a prerequisite, you should run npm run localnet-up and npm run deploy-dev to deploy your program to the solana test validator.

To deploy program and seed tx, simply run npm run localnet-up in one window and then run npm run dev-setup in another.

See README.

Troubleshooting:

Validate any tx:

solana confirm <txhash>

Open up logs (in a dedicated shell) - this usually has more detailed error info:

solana logs

Check balance:

solana balance

Check an account:

solana account <acct-pubkey-or-path-to-storage-keypair.json>

Check a program:

solana program show <program-id>

Airdrop funds:

solana airdrop <num SOL> <pubkey-or-path-to-storage-keypair.json>

Deploying to non-local cluster:

Can also specify a particular cluster at deploy time, per the following:

anchor deploy --provider.cluster https://audius.rpcpool.com/
Deploying workspace: https://audius.rpcpool.com/
Upgrade authority: /Users/hareeshnagaraj/.config/solana/id.json
Deploying program "audius-data"...
Program path: /Users/hareeshnagaraj/Development/audius-protocol/solana-programs/anchor/audius-data/target/deploy/audius_data.so...
Program Id: EoDXzUBiESoz9FEYdTScXgmfmzBKDRLVxgnNkFjpKtJc
