Lesson 10: Theorical question about the LendingPoolAddressesProvider

[carlitox477]

I was on the part where we need to code the get_lending_pool function. Here, of course we need to get our LendingPool address to interact with the contract on the testnet or mainnetfork, but instead of getting it directly by setting the actual contract address Patrick and aave documentation suggest to get this address from the LendingPoolAddressesProvider because the LendingPool address may change (at least this is what I undestood). However, why will the LendingPool address change?

PD: "change" may not be accurate (contracts can't change), be useless maybe is more accurate

Hello @carlitox477, if you take a deeper look into aave you will see there are different versions of the protocol they use, like aave v1 and aave v2, so on those upgrades the lending pool address will change, also you are right contracts can't change, but you can upgrade them as you'll see on lesson 12, so the address could change at upgrading. This is not something that is going to happen often but is worth to take it in consideration.

In a personal note I prefer using providers as they are more decentralized an secure.

Best regards.
