Lending

ttoken

Contains all the ways to interact with a tToken, which include minting, burning and even strategies. Let's take a look at what's under the hood here.

• strategies

  • ITTokenStrategy The interface with the functions required to be implemented in a Dapp strategy contract. It contains the strategy to rebalance(), allows users to withdraw() from a pool or give us the totalUnderlyingSupply() of an underlying asset.

  • compound So far, we only have one current strategy for our ttoken and that is related to the compounddecentralized application

    • The logic of this strategy is found in the TTokenCompoundStrategy.sol

    • More info on the compound strategy can be found here. Note that it implements the ITTokenStrategyinterface

• TToken contains all the functions required to interact with a ttoken

  • It is ERC20Upgradeable, which means we can upgrade the interface contract to add more functions down the line

  • You can find the code here

  • It can get/set strategies, fund/repay loans, burn tokens to redeem profit and get other metadata of the respective ttoken.

• LendingFacet.sol contains all the functions required to both create a lending pool (to allow DeFi developers to create their own markets) and to deposit into a pool. Depositing into a pool transfers the underlying asset to the pool and mints new ttokens of the underlying asset into the lender's wallet
