🔨 Build Your WASM Contract
Compile your AssemblyScript source into a .wasm binary that OP_WALLET will accept for deployment. This requires Node.js 18+ installed locally.
1
Extract & open the project
Unzip your downloaded package and open a terminal in that folder.
2
Install dependencies & compile
npm install
npm run build
This installs @btc-vision/btc-runtime and compiles your contract to build/MyToken.wasm.
Get Node.js ↗
3
Locate your WASM file
After a successful build you'll find build/MyToken.wasm — this is your compiled smart contract, ready to upload.
🚀 Deploy via OP_WALLET
OP_NET contracts are deployed by uploading your compiled .wasm file directly through the OP_WALLET browser extension. No third-party relayers — pure Bitcoin L1.
1
Install OP_WALLET
If you don't have it yet, install the OP_WALLET Chrome extension. It's the official wallet for OP_NET and all Bitcoin L1 smart contracts.
Install OP_WALLET ↗
2
Switch to OP_NET Testnet & fund wallet
Open OP_WALLET, select the correct network in the top-right corner. You need a small BTC balance for the deployment transaction fee. Get free tBTC from the faucet below.

3
Upload your WASM and deploy
In OP_WALLET, click the Deploy button. Drag and drop (or browse to) your build/MyToken.wasm file. Review the transaction and click Sign & Broadcast.
4
Wait for confirmation
The deployment is confirmed in Bitcoin blocks (typically 10 minutes). OP_WALLET will show your new contract address once confirmed — it starts with op1... (P2OP format, unique to OP_NET contracts).
✅ Register Your Deployed Token
After OP_WALLET confirms your deployment, copy the contract address (starts with op1...) and paste it below to track it on your dashboard.

This is the op1... address shown in OP_WALLET after deployment confirms
