Hi, tonight we will be making an upgrade to the TrueFi Smart contract suite. This upgrade adds a liquid exit feature allowing for increased liquidity for TFI-LP holders when there is TUSD available in the pol. This upgrade also fixes a bug in TFI-LP price calculation when a loan has been repaid, but not set as closed in the pool contract.

The following changes are going into effect:

- Stop using infinite approval in curve
- Remove whitelist from TrueLender and require LoanTokens are deployed by borrower instead
- Fix loans value calculation (in LoanToken & TrueLender)
- Add cooldown on exit to prevent arbitrage
- Treat year as 365 days
- Add limit to total number of loans in TrueLender (100)
- Add view method for claimable and claimed rewards
- Restrict loan funding to lender
- Fix distributions after empty() was called
- Prevent borrower from repaying with surplus
- Add liquidWithdraw mechanism
- Add reclaim function to LoanToken
- Added arg validation and events
- Set burn & loss factor in accordance with spec
- Set slippage for withdrawing from curve

Below are the new smart contracts:

TrueFiPool: [Contract Address 0x3Fe853e7E5f78C00405fC80DAF7f7baDE2E53E46 | Etherscan](https://etherscan.io/address/0x3Fe853e7E5f78C00405fC80DAF7f7baDE2E53E46#code)  
LoanFactory: [Contract Address 0x979D49C4813CD68005df1c97c05365bbaE76550D | Etherscan](https://etherscan.io/address/0x979D49C4813CD68005df1c97c05365bbaE76550D#code)  
TrueRatingAgency: [Contract Address 0x57FeA15015C8f0Fd35B3A25f57A75a94656B1769 | Etherscan](https://etherscan.io/address/0x57FeA15015C8f0Fd35B3A25f57A75a94656B1769#code)  
TrueLender: [Contract Address 0xBF172BE09325612392a41a0D8a5d8ee6aB895f95 | Etherscan](https://etherscan.io/address/0xBF172BE09325612392a41a0D8a5d8ee6aB895f95#code)

Cheers!

@hal on [https://app.truefi.io/farm](https://app.truefi.io/farm) I see three active pools. Can you please share etherscan links for these three pools?
