Deploying an OP_20 Token on OP_NET

Bitcoin AssemblyScript TypeScript NodeJS WebAssembly NPM

code style: prettier

Prerequisites

  • Ensure you have Node.js and npm installed on your computer.

Step-by-Step Guide

1. Install OP_WALLET Chrome Extension

2. Obtain Testnet Bitcoin

  • If you don't have any Testnet3 Bitcoin, get some from this faucet.

3. Download OP_20 Template Contract

4. Edit Token Details

  • Open the OP_20 template repository in your IDE or text editor.
  • Navigate to src/contracts/MyToken.ts and find lines 15-18: 
          const maxSupply: u256 = u128.fromString('100000000000000000000000000').toU256();
      const decimals: u8 = 18;
      const name: string = 'Testnet';
      const symbol: string = 'TEST';
  • Modify the number for the total supply and the amount of decimals (e.g., for 18 decimals, add 18 zeros).
  • Change the name and symbol of the token as desired.

5. Install Dependencies and Build

  • Open your terminal and navigate to the location of the downloaded OP_20 template folder.
  • Run the following commands: 
    npm install
npm run build
  • After building, a build folder will be created in the root of the OP_20 folder. Look for [nameoftoken].wasm for the compiled contract.

6. Deploy the Token Contract

  • Open the OP_WALLET extension and select the "deploy" option.
  • Drag your .wasm file or click to choose it.
  • Send your transaction to deploy the token contract onto Bitcoin with OP_NET.

7. Mint Token Supply

  • After deploying the token, you will need to mint the supply you wish to have.
  • Open your OP_WALLET, click the token in your balance that you just deployed, and select the "mint" option.
  • Click "max" or type in the amount of tokens you wish to mint, and then send the transaction.

8. Add Liquidity on Motoswap

  • Copy the token address from your OP_WALLET.
  • Go to Motoswap and paste your token address into the top or bottom box.
  • Enter the amount of tokens you wish to add to the liquidity pool.
  • Select the other side of the liquidity pair (e.g., WBTC) and enter the amount of tokens you wish to add.
  • Click "Add Liquidity".

Your token is now tradeable on Motoswap!

Congrats!

You have successfully deployed and minted your OP_20 token on the Bitcoin blockchain using OP_NET, and added liquidity to make it tradeable on Motoswap.
