loan: July 2023 airdrop claiming instructions

Airdrop claiming instructions, provided by Archblock


The airdrop comes in the form of an ERC4626 tokenized vault (00xfBc33285d9f58d34fE239bFA3732036d5c53a1665), with mints and deposits disabled. This contract has undergone an internal security review and an external audit by ChainSecurity.

Shares of the airdrop are proportional to token holders of the tfUSDC lending pool as of January 9, 2023, the original end date of the loan. This includes lenders who farmed their tfUSDC holdings, as well as claimable tfUSDC rewards from the stkTRU contract.

In order to prevent locked funds in the contract, users will have until a deadline of January 21, 2024, to redeem your shares of the interest airdrop.

After this date, TrueTrading will recover the remainder of funds.

You may want to wait until gas prices are low before calling the redeem( ) function.
