From project root:

cargo build --release

Output: target/wasm32-gear/release/one_of_us.opt.wasm

If you need to interact with your program from Solidity contracts or use Ethereum ABI tooling:

cargo sails sol --idl-path ./target/wasm32-gear/release/one_of_us.idl

Output: OneOfUs.sol — contains interface, ABI contract, and callback definitions.

cd deploy
npm install
cp .env.example .env

If you plan to deploy with Solidity ABI interface, install Foundry:

curl -L https://foundry.paradigm.xyz | bash
foundryup

Then install dependencies from project root:

forge install

Variables appear in order as you complete each step:

# Initial setup (required)
PRIVATE_KEY=0x...           # Your Ethereum private key
ETH_RPC=https://...         # Ethereum HTTP RPC (Hoodi)
ETH_RPC_WS=wss://...        # Ethereum WebSocket RPC (for subscriptions)
ROUTER_ADDRESS=0x...        # Router contract
WVARA_ADDRESS=0x...         # wVARA token contract
VARA_ETH_WS=wss://...       # Vara.eth WebSocket (for injected tx)

# For Etherscan verification (optional but recommended)
ETHERSCAN_API_KEY=...       # Get from hoodi.etherscan.io

# After upload (step 1)
CODE_ID=0x...               # Validated code hash

# After create (step 2)
PROGRAM_ID=0x...            # Program Mirror address
ABI_ADDRESS=0x...           # ABI contract address (if using Option B)

⚠️ Important: Wait for Ethereum finalization after each step before proceeding to the next.

npm run upload

→ Get CODE_ID, add to .env

Option A: Standard creation

npm run create

→ Get PROGRAM_ID, add to .env

Option B: With Solidity ABI interface (using Foundry)

This option deploys an ABI contract and links it to your program, enabling interaction via standard Ethereum ABI tooling.

# 1. Generate Solidity interface from IDL (if not done already)
cargo sails sol --idl-path ../target/wasm32-gear/release/one_of_us.idl

# 2. Deploy ABI contract and create program in one step
npm run create:abi

This script:

• Deploys OneOfUsAbi contract using Foundry (forge script)
• Automatically verifies on Etherscan (if ETHERSCAN_API_KEY is set)
• Creates program with ABI interface via Router

→ Get PROGRAM_ID and ABI_ADDRESS, add to .env

After deployment, link your Mirror contract to the ABI contract on Etherscan:

1. Go to your PROGRAM_ID (Mirror) address on Hoodi Etherscan
2. Click the "Code" tab
3. Click "More Options" → "Is this a proxy?"
4. Click "Verify" — Etherscan will detect the ABI contract
5. Confirm the linking

Once linked, the Mirror contract page will show all ABI methods (Read/Write Contract tabs), making interaction much easier.

npm run fund

→ Program receives wVARA balance

npm run init

→ Program is ready to use

Classic transaction (via Ethereum):

npm run classic

Injected transaction (instant pre-confirmation):

npm run injected
