Ethereum ecosystem has plenty of finance protocol and the places where people tend to stake their tokens. And based on the stake percentage and also the approved DAO percent for the returns, you would find the two tokens being good on the ecosystem for growth. 

Maple is one asset management chain which has been helping the investors with the asset management with their SYRUP tokens. So they have like USDC and USDT version of their syrup stablecoins. 

The market that maple has it's easier for them to establish the lenders and borrowers on the chain. And now attaching themselves with the AAVE finance they can go on the other markets within the markerplace. Like say Plasma market is where their USDC would be listed and same would happen to the USDT as well. 

Currently this is going through the proposal. And there would be approval and it would get listed. You can check out the proposal link here for the syrupUSDT to Aave V3 Plasma Instance. And this goes to show you how the liquidity protocol and market listing would benefit in the ecosystem and more of such programs under ethereum would only benefit the chain.
