In a typical AMM, the staker would have initially deposited X amount of SOL and Y amount of USDC; after some time, he would have been able to withdraw Xโ amount of SOL and Yโ amount of USDC. Because ZAMM is not trading on top of SOL-USDC orderbook, but rather on SOL-PERP orderbook, ZAMMโs SOL balance always remains the same. Consequently, there is a chance that if ZAMM lets users withdraw SOL, it will eventually run out of SOL to hand out.
