Verifying DEX smart contracts
Now we have implemented the smart contracts for DEX's fundamental features, here we will call the public or external functions from AMMRouter to verify these features. The AMMRouter smart contract provides interfaces for off-chain activities to access the DEX. Other components of the DEX, such as TokenPair and PairFactory, can also be verified by accessing AMMRouter.
Deploying AMMRouter with a script
Similar to other smart contracts, AMMRouter can also be deployed through scripts/deploy.js. However, there is one difference in that AMMRouter requires a _factory parameter in its constructor for the deployment, which needs PairFactory to be deployed before AMMRouter, and uses the deployed pairFactoryAddress as the argument when calling the deploy function in JavaScript:
await contractFactory.deploy(pairFactoryAddress)
We need to refactor the script in the main function to deploy PairFactory before deploying AMMRouter. You can check the updated...
