Direct Contract Interaction
Prerequisites
Ensure that Node.js and npm are installed on your machine.
Step 1: Install Ethers.js
Use npm
to install ethers.js
:
Step 2: Connect to the Network that You'd Like to Add Liquidity to
Connect to Ethereum, for example. You can do this using a default provider from ethers, which automatically connects to the Ethereum mainnet:
Step 3: Import the Contract ABI and Address
The contract ABI and address will enable ethers.js
to interact with the contract. Import these values:
Step 4: Create a Contract Instance
Now, using the provider, the contract ABI, and the contract address, you can create a contract instance:
Step 5: Create a Signer
In order to modify the blockchain state, transactions need to be signed. Create a signer from a private key:
Make sure to replace 'your-private-key'
with your actual private key.
Step 6: Connect Contract to Signer
Connect the contract instance to the signer:
Step 7: Interact with the Contract
Now that you have a contract instance connected to a signer, you can interact with the contract's functions.
