bton/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.cell) and deploy init data scripts (mycontract.deploy.ts)
//  ./build/deploy.config.json - JSON config file with secret mnemonic of deploying wallet (will be created if not found)
