Active Proposal

  • [SIP1.​1.​1] USDC Vault upgrade on Arbitrum is live for voting
  • Deploys full 11-Ark fleet with cross-chain governance via LayerZero
  • No bridged tokens required

Forum Discussions

Multiple RFCs propose expanding yield sources:

  • USDC Mainnet: Clearstar reactors, MidasRWA vaults, Upshift strategies
  • ETH Mainnet: Clearstar Reactor ETH, Ether.​fi Liquid ETH
  • Base USDC: Clearstar reactors, 40acres Finance, Universal.​fi
  • Arbitrum USDC: Clearstar USDC Reactor
  • MIDAS integration: Evaluating RWA vaults for Mainnet and Base
  • ExtraFi XLend: Adding ETH pool to Base Lower-Risk vault

Key Features

  • Sustainable yield via OP/EXTRA incentives
  • Multi-account lending architecture
  • Automated risk controls

These proposals will shape upcoming vault upgrades across the protocol.​

Summer.fi Releases Post-Mortem on Arbitrum USDC Vault Incident

**Summer.fi published a detailed post-mortem** on the Arbitrum USDC Vault incident that affected users. **Root Cause Identified** - Balancer v2 exploit led to USDX depeg - Silo's oracle failed to reflect real losses onchain - Arbitrum USDC Vault inherited incorrect valuations **Protocol Response** - Lazy Summer Protocol relies solely on onchain data - Since Silo's oracle showed full backing, vault share prices didn't adjust - This allowed withdrawals until liquidity was depleted **Summer.fi's Actions** - Deployed UI warnings immediately - Created snapshot of affected users - Developed recovery monitoring contracts **DAO Discussions Underway** - Offboarded problematic vault - Onboarded new Arbitrum USDC Vault - Guardian Framework for emergency controls - Compensation discussions ongoing Summer.fi emphasized this was an **upstream failure**, not a protocol issue. The team commits to transparency and supporting the community through recovery efforts.
