Development

Building the client

You can build the Typescript client locally:

npm install
npx hardhat compile
npm run build

Testing

Run the test suite:

npm test

Test with gas reporting:

REPORT_GAS=true npx hardhat test

Deploying

Deployments are handled on a per-network basis:

npx hardhat run scripts/deploy.ts --network optimism

Network names may include context for the target Tableland network:

npx hardhat run scripts/deploy.ts --network optimism-goerli-staging

Where optimism-goerli-staging indicates a deployment to the Optimism Goerli testnet for the Tableland staging network.

Refer to proxies in network.ts for the list of current deployments.

Upgrading

The Tableland contracts are currently upgradeable at this early stage of development. Upgrades are handled much like deployments:

npx hardhat run scripts/upgrade.ts --network optimism

Upgrading on a network only works if a previous deployment already exists, referenced by proxy address in network.ts.

Extacting the ABI and Bytecode

You can you grab the assets you need by compiling and then using some jq magic:

ABI

cat artifacts/contracts/TablelandTables.sol/TablelandTables.json | jq '.abi' > abi.json

Bytecode

cat artifacts/contracts/TablelandTables.sol/TablelandTables.json | jq -r '.bytecode' > bytecode.bin

Generate the Go client!

You can use the above abi.json to build the Go client:

mkdir gobuild
abigen --abi ./abi.json --bin ./bytecode.bin --pkg contracts --out gobuild/Registry.go

Etherscan verification

To perform Etherscan verification, you first need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Goerli:

npx hardhat run scripts/deploy.ts --network ethereum-goerli

Then, copy the deployment address and paste it in to replace DEPLOYED_CONTRACT_ADDRESS in this command:

npx hardhat verify DEPLOYED_CONTRACT_ADDRESS --network ethereum-goerli

Speedier tests

For faster runs of your tests and scripts, consider skipping ts-node's type checking by setting the environment variable TS_NODE_TRANSPILE_ONLY to 1 in hardhat's environment. For more details see the documentation.
