How to run WOO OFT

---

• install dependencies
  • pnpm install
• rename .env.example → .env
  • put the mnemonic of the test wallet of ethereum
  • use scripts/getBase58Pk.js to generate SOLANA_PRIVATE_KEY
• rename layerzero.config.dev.ts to layerzero.config.ts
• rename hardhat.config.dev.ts to hardhat.config.ts
• compile the contract
  • pnpm compile:hardhat
• Prepare Program ID
  • solana-keygen new -o target/deploy/endpoint-keypair.json --force
  • solana-keygen new -o target/deploy/oft-keypair.json --force
  • anchor keys sync
  • change program/src/oft/lib.rs with new program id

• build Solana OFT program
  • anchor build
  • don’t add -v for verified build as its too slow
• deploy Solana OFT program
  • solana program deploy --program-id target/deploy/oft-keypair.json target/deploy/oft.so -u devnet
• Create Solana OFT
  • pnpm hardhat lz:oft:solana:create --eid 40168 --program-id EaWXNTXSauuEWUyzBATCCbLfscNAgxS4bfQHnTGKeFXY --only-oft-store true --name WOO --symbol WOO
  • open ./deployments/solana-testnet/OFT.json , find OFTStore = DKrx8GxUMBwJ1dDDpiJkdBvx31T7fxM3sqzCf2FPsNg9
  • change layerzero.config.ts with DKrx8GxUMBwJ1dDDpiJkdBvx31T7fxM3sqzCf2FPsNg9
• deploy the contract to Ethereum Sepolia
  • first create a test WOO ERC20 token on Sepolia using https://coinfactory.app/, here is the contract: https://sepolia.etherscan.io/token/0xDd481A5FBa15E777fd73493E505C057fe16b0955#readContract
  • set the contract address as wooTokenOnSepolia in deploy/WooTokenOFTAdapter.ts
  • npx hardhat lz:deploy
  • tag use WooTokenOFTAdapter
  • https://sepolia.etherscan.io/token/0xd73E4a225f973EA0615EfeB2a23aAb33Ac5759F9#code
• initialize the OFT
  • npx hardhat lz:oapp:init:solana --oapp-config layerzero.config.ts --solana-secret-key <SOLANA_PRIVATE_KEY> --solana-program-id EaWXNTXSauuEWUyzBATCCbLfscNAgxS4bfQHnTGKeFXY
• wire the config
  • npx hardhat lz:oapp:wire --oapp-config layerzero.config.ts --solana-secret-key <SOLANA_PRIVATE_KEY> --solana-program-id EaWXNTXSauuEWUyzBATCCbLfscNAgxS4bfQHnTGKeFXY
