This is why I love [Summer.fi](http://Summer.fi) as a user. I can just chill while the gigabrains keep the yield high. Good work. ---

Arbitrum’s fleet looks like it’ll benefit from a healthy mix of Morpho, Euler (not yet present in the fleets), and Silo strategies across both USDC and USD **₮** 0. I hope we can avoid concentration and liquidity mismatches. Thanks @samehueasyou for the proposal! > [@Raphael\_Anode](#): > > I can just chill while the gigabrains keep the yield high. Lazy Summer, innit! \<3 ---

Well done @samehueasyou and Delegates 👏 👏 👏 ! The new ARKs for the Arbitrum USDC (Lower Risk) vault have been a stellar addition. They brought in over **$2M in FRESH TVL** and another $1M from vault switchers. Even with TVL roughly doubling, the vault continues to deliver **juicy yields** and holds [3rd place in the any-chain USDC rankings](https://app.vaults.fyi/discover?searchFor=usdc&sortBy=apy&asc=false) on vaults.fyi. Well done! 👏 👏 👏 [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates) ![Screenshot from 2025-09-13 14-50-58](https://canada1.discourse-cdn.com/flex009/uploads/summer/original/1X/9281acf2578b1528cc796904f0d826c4cc8df61c.png) ![Screenshot from 2025-09-13 14-43-54](https://canada1.discourse-cdn.com/flex009/uploads/summer/original/1X/10d0023c67426db02205ab544b655b4131d789b7.png) ![Screenshot from 2025-09-13 14-40-28](https://canada1.discourse-cdn.com/flex009/uploads/summer/original/1X/6ea46ee6294ba1f3c0d3bbb4fa7dcf4daa140838.png) ---
