LitePSM
LitePSM is a gas-efficient implementation of the Peg Stability Module (PSM), designed to facilitate seamless swaps between DAI, USDS, and external stablecoins such as USDC, with no slippage. Unlike the original PSM, which was gas-intensive due to direct interactions with the MakerDAO Vat, LitePSM enables swaps using a pool of pre-minted DAI or USDS, reducing each transaction to two simple ERC-20 token transfers.
Key features of LitePSM include permissionless functions to maintain pool stability, the ability for authorized parties to execute no-fee swaps, and the option to segregate gem balances for yield generation. This version is backward compatible and designed to optimize gas costs while supporting the security and operational requirements of the Sky ecosystem.
Please refer to the LitePSM User Guide for additional details about the module.
