[Ethereum, Arbitrum, Base] Update Rate Limits
AI summary
This proposal from Phoenix Labs, Spark's nested contributor, seeks to update rate limits for various digital assets across Ethereum, Arbitrum, and Base. It will set deposit and withdrawal limits to zero for Aave USDS, USDC, and Fluid sUSDS integrations, as these are no longer used. Conversely, it will significantly increase rate limits for USDT and ETH-related integrations to support the growth of Spark Savings ETH (spETH) and USDT (spUSDT) vaults. The proposal also shifts risk mitigation from low 'maxAmount' limits to proactive off-chain monitoring.
If passed, Spark will no longer support certain Aave and Fluid stablecoin integrations, potentially affecting users of those specific assets. The increased rate limits for USDT and ETH could lead to greater capital flow into Spark's savings vaults, benefiting users of spETH and spUSDT. The new risk mitigation strategy relies more on active monitoring, which could expose the protocol to up to $750,000 in potential daily losses from market impact/slippage in specific scenarios, though this is deemed acceptable given rapid fault containment.
