contracts/build/_deploy.ts

// This is a simple generic deploy script in TypeScript that should work for most projects without modification
// Every contract you want to deploy should have a mycontract.deploy.ts script that returns its init data
// The script assumes that it is running from the repo root, and the directories are organized this way:
//  ./build/ - directory for build artifacts (mycontract.compiled.json) and deploy init data scripts (mycontract.deploy.ts)
//  ./.env - config file with DEPLOYER_MNEMONIC - secret mnemonic of deploying wallet (will be created if not found)
