♾️2.1 Deposit Tokens & Global Trackers

2.1 Deposit tokens

In order to address donation and reentrancy attacks, the following measures were adopted:

• No withdraws of native ether, only wrapped ether (WETH)

• Underlying borrow and collateral tokens (USDC and WETH) are converted 1:1 into ERC-20 deposit tokens via deposit, which mints szaUSDC and szWETH, and received back via withdraw, which burns deposit tokens 1:1 in exchange for the underlying tokens.

Deposit tokens are non-transferable.
