[ARC] Increase Supply Cap of sUSD on v3 Optimism (Fast-track)

Current parameters:

Supply cap: 10M sUSD20m sUSD (proposed increase of supply cap)

DEX Liquidity: ~$50m+

Normal mode:

LTV: 60%

Liquidation threshold: 75%

Liquidation penalty: 5%


Assets: Stablecoins

Max LTV: 97%

Proposal: Increase of supply cap by 100% to 20m sUSD

The current sUSD supply cap on v3 is 10m sUSD and has been reached shortly after the launch of AAVE and Optimisms liquidity mining program on AAVE V3.

The proposal’s goal is to suggest an increase of 100% to 20m sUSD supply cap via the fast-track process as outlined here

Reasons for increase:

  1. sUSD Dex Liquidity: Despite market conditions, sUSD DEX liquidity vastly increased across Optimism on Curve, Uniswap, Velodrome, and others. This can facilitate healthy liquidations if ever necessary.

  2. sUSD’s Healthy Peg: Throughout the entire time sUSD has been an asset on AAVE, it has held peg and has not decreased within 1% of the expected peg of $1. This is due to increased sUSD Dex liquidity, and constant arbitrage of the peg by market makers.

  3. Optimism Liquidity Mining: Due to the ongoing OP liquidity mining program on AAVE V3, the sUSD supply cap has been hit very quickly. To ensure that more users are able to supply/borrow on AAVE, it is important to increase this supply cap to ensure that there is ample amounts of sUSD available on AAVE.

We look forward to the discussion on increasing the Supply Cap of sUSD on v3 by 100% to 20m sUSD.

Note: We’ve used the template set by sAVAX when they’ve increased their supply cap via Fast-Track as well.


I’m in favour of this proposal,

there are natural synergies between SNX stakers and sUSD minters on OP and Aave LP.

This proposal seems fit for the fast-track process to change caps. if community agrees a vote by snapshot can be published in 24h.
