Factory smart contract

We use a factory pattern that's responsible for creating new cap tables and managing the cap table addresses. You can find the smart contract in our repo under capTableFactory.sol (opens in a new tab).

Deploy the contract

Run the script to deploy the contract

With Anvil running, run our script:

yarn deploy-factory

Check the contract address in Anvil

In your terminal, you should get the contract address after the script runs. You can also check the contract address in Anvil.

./scripts/deployFactory.sh
+ cd chain
+ forge script script/CapTableFactory.s.sol --broadcast --fork-url http://127.0.0.1:8545

Manually add CapTableFactory to MongoDB

For this, you'll need to use Mongo Compass that you installed earlier. You can find the connection string in the .env file.

Under databases collection, search for factories and add the contract address to the collection using add data -> insert document.

{
	"implementation_address": "0x0DCd1Bf9A1b36cE34237eEaFef220932846BCD82",
  	"factory_address": "0x9A676e781A523b5d0C0e43731313A708CB607508"
}

Keep in mind that your contract address will be different from the one in the example.

Factories

With this done, you're ready to deploy the first cap table using the factory contract.
