DeFi is evolving toward greater transparency.
Proof of Reserves turns that into clearer, more reliable risk management - a key building block for the programmable economy.
Here’s how we’re bringing this to life on @arbitrum, where onchain economies scale 🧵
The rsETH incident left Aave with ~$177M to $196M in bad debt, while its Umbrella backstop held only ~$50M to $55M for ETH.
The backstop covered only a fraction. In most designs, junior buffers float freely against Senior TVL, so protection drifts from exposure, and by the time stress hits, the gap is too wide to close.
PrimeVaults V2 takes a different approach:
Coverage is enforced on-chain and scales with TVL, so protection and risk stay aligned. If coverage weakens, the system responds on its own, step by step:
1️⃣ Assets lock → withdrawals move to fixed-asset mode
2️⃣ Shares lock → exits are delayed, with mark-to-market risk
3️⃣ Senior mint pause → new Senior capital is paused until coverage recovers
Senior remains open, but its growth is capped while coverage is low. Redemption fees adjust upward, helping coverage rebuild from both directions.
No governance vote. No delay. The logic runs on its own.
And the incentives self-correct: Lower coverage → higher Risk Premium → yields rise on protected layers → capital flows back in to restore the buffer.
It's a living system that reacts, adjusts, and rebuilds itself when it matters most.
We'll be publishing a full breakdown of Prime Vaults V2, a structured on-chain yield protocol, in the coming weeks. Follow along for updates.
Update on rsETH incident:
@LlamaRisk has published a report outlining the rsETH incident, the immediate actions taken, its impact on Aave, and potential paths forward.
All service providers have been working to assess the two potential bad debt scenarios on the Aave protocol.
Aave DAO service providers are also leading an effort with ecosystem participants to address any bad debt. This effort already has several indicative commitments from various parties and we are grateful for the strong support we have received so far.
We will share further updates as we have them.
In the meantime, the full report can be read here: governance.aave.com/t/rseth-…

.@arbitrum is evolving from an L2 into core infrastructure for enterprise blockchains.
✓ Leading L2 by activity: ~$1.9B DeFi TVL, #2 Uniswap deployment, and ~$4B in stablecoin market cap signal sustained onchain demand (DeFi Llama).
✓ Gaining traction in RWAs: Ranked #1 by RWA count as of April 1 (rwa.xyz), positioning Arbitrum at the center of tokenized asset growth.
✓ A new economic model for chains: The Arbitrum Chain stack applies a 10% fee on net protocol revenue for chains not settling to One/Nova.
✓ Robinhood Chain uses the Arbitrum tech stack and stands to be a bellwether for this model as tokenized stock activity ramps up.
