Adding a LUSD wrappr on L2 that mints 1 sUSD for each 1 LUSD deposited and releases 1 LUSD for each sUSD burned (excluding fees).
\nThis SIP proposes to add the LUSD/sUSD wrappr using the wrappr factory specified in SIP-182.
\nAlthough the original ETH/sETH wrappr specifies wrapping a synth with it's respective underlying, this SIP proposes wrapping sUSD with a derivative of US Dollars (LUSD). Therefore there are certain risks involved that need to be highlighted to the snx community:
\n(1) In the case where the LUSD is trading at a discount against USD, the debt accounting will be flawed until a patch is in place (unwinding the LUSD with negative burn rates). This might lead to significant sell pressure on synths, if a substantial amount of the synth supply is minted by LUSD. After unwind the debt on snx stakers is expected to increase.
\n(2) In the case where LUSD is trading at premium against USD, the LUSD wrappr might not be optimal in peg alignment.
\nNevertheless, the fundamental benefit of adding the LUSD/sUSD wrappr, is that it allows unwinding a censorship prone DAI wrappr, SCCP-147, which exposes snx stakers to the risk of DAI depeg stemming from USDC censoring.
\nThe sUSD/LUSD wrappr will function similar to the sUSD/DAI wrappr, where a users can mint 1 sUSD for each LUSD deposited and where users can burn 1 sUSD to receive back 1 LUSD (excluding fees).
\nSupporting, LUSD/sUSD wrappr can still be considered to be acceptable in terms of risk, if it is used with limitations on the cap amount. Furthermore, diversification with other censorship resistant stable coins might also help spreading the risks involved and lowering the overall exposure on snx stakers.\nIt is important to stress the need to rely on stablecoin wrapprs, as opposed to more volatile crypto-currencies, due to the negative skew impact on the debt pool when relying on a substantial amount crypto-currency wrapprs (as is the case on L1).\nIn the long run, these stable coin wrapprs might not be needed as following the implementation of SIP-165, L1 sUSD and L2 sUSD can be interchanged and therefore sUSD supply on optimisim is expected to grow organically.
