ARC: enable sUSD as collateral

Summary :

sUSD is a decentralized stable coin which is over collateralized by the SNX token. sUSD is already listed on AAVE markets as a lendable asset as well as SNX which can be used as collateral in addition to borrow/lending. There is significant liquidity for sUSD on Dexes such as Curve, Sushiswap and Balancer, I am proposing for it to be enabled as collateral on AAVE.

References :

Curve sUSD pool - TVL $196M / $35.9M sUSD

Sushiswap sUSD / ETH pool - TVL $30.8M / $15M sUSD

Balancer sUSD / sTSLA 80/20 pool - TVL $9.3M / $7.3M sUSD


sUSD market cap has grown tremendously over the past year and the steady demand for decentralized stable coins has contributed to its growth. sUSD is highly over collateralized by SNX, the governance token and backstop for the Synthetix protocol.
The rise in its liquidity on major dexes has contributed to sUSD stability over the past year and allowing collateral use would promote its liquidity in aave markets.
With over with over 25% of the sUSD supply liquid on chain, in AMMs, sUSD is a viable candidate for collateral on AAVE.


SNX stakers are incentivized to actively manage their dept relative to their SNX stake and in doing so sometimes cause spikes in demand for sUSD on markets including AAVE (specially when their are other Yield generating opportunities with sUSD), this may cause small deviations from the peg but with low volatility.
All underlying functions in relation to sUSD, are fundamentally the same, from a counter-party risk perspective, to that of SNX.
The SNX and sUSD contracts are fully upgradeable, but all changes must go through a formal governance process from SIP to deployment, which would be announced well before the upgrades are made and thus does not present a substantial counter-party risk.
The sUSDv2CRV pool is one of the main CurveDAO emissions gauges, incentivizing sustainable longterm liquidity for sUSD.
In addition to sUSD there are other synth pools on Curve with emission gauges to supplement sUSD liquidity (sBTC, sETH ). All synths are redeemable at their dollar value in sUSD at the ChainLink quoted price, through the Synthetix protocol or Curve (via cross-asset swaps), thus they help facilitate the arbitrage of sUSD peg deviations.
