Part 3: Emergency Depeg Fee Protection & TWAP Sources

Stabilizer’s Multi-Venue TWAP Monitoring for PYUSD:

Primary Venues:

  1. Curve Finace (Ethereum)
  • Pool: PYUSD/USDS
  • Pool: TVL: $100M
  • Link: Curve.finance
  • TWAP calculation window: 2-3 minutes
  1. Curve Finance (Ethereum)
  • Pool: PYUSD/USDC
  • Pool: TVL: $50M
  • Link: Curve.finance
  • TWAP calculation window: 2-3 minutes
  1. Chainlink Oracle (Fallback)

Depeg Fee Example:

If PYUSD depegs to $0.97 (3% depeg):

  • Average TWAP: (Curve PYUSD/USDS $0.9720 + Curve PYUSD/USDC $0.9700 + Chainlink $0.9710) / 3 = $0.9710
  • Emergency fee activates: 2.9%
  • Arbitrage profit: 2.9% - 2.9% = 0%
  • LPs fully protected :white_check_mark:

PYUSD Approval: Consensus Reached

Strong write-up, arthur. The structured breakdown makes this easy to verify independently which is exactly what a governance post like this should look like.

My Thought:

On the concentration flag: he 67.73% Sentora concentration is the one number that deserves closer scrutiny. Even with PYUSD’s strong fundamentals, single-protocol concentration at that level means a Sentora-side liquidity event could temporarily stress PYUSD’s on-chain depth regardless of the peg holding. Worth defining a concentration threshold in the collateral parameters and revisiting if Sentora’s share grows further.

On the TWAP setup: the 3-source averaging (Curve PYUSD/USDS + Curve PYUSD/USDC + Chainlink fallback) is well-designed. The 2-3 minute window feels appropriate for a stablecoin of this liquidity depth. Would be good to explicitly document the fallback priority order in the deployment config, Chainlink should probably activate before TWAP divergence widens too far.

On the oracle address: the “to be configured per deployment” placeholder in Part 3 should be resolved before approval goes to vote. Leaving that open in a live governance post is a minor gap.

Overall: the NYDFS oversight + monthly Paxos attestations + Bluechip A- rating is about as clean a regulatory and transparency profile as you’ll find in this space. Support moving this to vote after the 48-hour window assuming the oracle address gets confirmed.

:white_check_mark: In favor of approval.

you always have to look at the risks

Great assessment and research on PYUSD :clap:

One suggestion I would make is to continue monitoring liquidity concentration across protocols. While PYUSD appears very low risk, reducing dependence on a small number of liquidity venues over time could further strengthen resilience and improve long-term stability.

It would also be valuable to provide a public dashboard showing real-time risk metrics, peg health, liquidity distribution, and oracle status. This would increase transparency and help users better understand the assets supported by Stabilizer.

Looking forward to seeing more risk assessments like this for additional stablecoins in the future :rocket::balance_scale:

PYUSD has significantly lower liquidity than USDT or USDC, but its current market cap and trading volume appear sufficient for the proposed use case. The main consideration is that lower liquidity could lead to larger price deviations during periods of market stress, even if the issuer risk remains low.

PayPal USD (PYUSD) presents a Very Low Risk profile, making it a highly reliable asset for the Stabilizer deployment.

15

PYUSD very safe stable coin overall

16

not popular yet… but I believe with time it will enter the main-stream

18

The analysis suggests PYUSD is generally low risk due to strong regulation and peg stability, but the “very low risk” rating is overstated because liquidity concentration, custody dependencies, and missing stress-test data introduce non-trivial centralization risks.

19

nice assessment with credible sources and clear methodology.

PYUSD shows strong fundamentals: regulated issuer, audited contracts, transparent reserves, stable peg history, and sufficient liquidity. The DeFi concentration is worth monitoring, but overall the risk profile appears very low.

support moving forward to the discussion and approval phase.

This is very educational

I have been learning a lot of things

Maybe next time I will do better intake of my knowledge

Nice to see the risk assessment was passed

22

Solid assessment overall. What stood out to me most is how strong the issuer side looks with Paxos and the transparency around reserves.

I also like that the analysis doesn’t just focus on the peg but considers liquidity, smart contract risk, and external validation. As adoption grows, it’ll be interesting to see how PYUSD liquidity continues to spread across DeFi.
