## **Summary** This SIP proposes integrating [Origin Ether](http://oeth.com/) into the ETH Mainnet (Lower Risk) vault in the Lazy Summer Protocol. Extensive discussion and technical diligence have confirmed that OETH’s redemption mechanics, fees and other technical considerations meet Lazy Summer’s standards, see previous thread [[RFC] Onboard Origin Protocol’s OETH and OUSD as new ARKs within the Mainnet ETH and Mainnet USDT vaults on Lazy Summer Protocol](https://forum.summer.fi/t/rfc-onboard-origin-protocol-s-oeth-and-ousd-as-new-arks-within-the-mainnet-eth-and-mainnet-usdt-vaults-on-lazy-summer-protocol/159/) Adding OETH will diversify ETH yield strategies, tap into Origin’s unique liquid staking model, and expand Lazy Summer’s yield-generating sources beyond standard DeFi lending protocols. ## **Motivation** - **Expand yield sources** – Provides exposure to Origin’s staked ETH-backed product, adding a complementary ETH yield stream alongside existing ARKs. - **Attract new user types** – Engages current OETH holders, deepening penetration into the ETH staking ecosystem. - **Increase TVL** – Adds a ETH ARK, supporting Lazy Summer’s ETH vault growth objectives. ## **Specification** | **Parameter** | **Value** | | --- | --- | | **Vault** | ETH Mainnet – Lower Risk | | **Network** | Ethereum Mainnet | | **New ARK** | OETH | | **Contracts** | Standard: [0x856c4Efb76C1D1AE02e20CEB03A2A6a08b0b8dC3](https://etherscan.io/address/0x856c4Efb76C1D1AE02e20CEB03A2A6a08b0b8dC3) Wrapped 4626: [0xDcEe70654261AF21C44c093C300eD3Bb97b78192](https://etherscan.io/address/0xDcEe70654261AF21C44c093C300eD3Bb97b78192) | | **Risk Level** | Lower Risk | | **$SUMR Rewards** | In line with ETH Lower Risk SUMR Rewards | @BlockAnalitica provided their recommendation for this OETH ARK here: [[RFC] Onboard Origin Protocol’s OETH and OUSD as new ARKs within the Mainnet ETH and Mainnet USDT vaults on Lazy Summer Protocol - #13 by BlockAnalitica](https://forum.summer.fi/t/rfc-onboard-origin-protocol-s-oeth-and-ousd-as-new-arks-within-the-mainnet-eth-and-mainnet-usdt-vaults-on-lazy-summer-protocol/159/13) @jensei [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates) @chrisb @halaprix @0xtucks @samehueasyou ​ ​ ​ ​ ---

Love to see this one finally make its way to SIP, thanks for driving it forward @pete. Thanks to @BlockAnalitica for the risk assessment as well! > \*I have adjusted the SIP number from **2.14** to **2.15** due to overlap with previously posted [**[SIP2.14]**](https://forum.summer.fi/t/sip2-14-onboard-hyperithm-morpho-usdc-to-the-usdc-mainnet-lower-risk-vault/248). The integration of **OETH** into the Mainnet lower-risk ETH strategy feels like a solid progression of our vault design goals: composability, yield optimization, and measured risk exposure. Supportive of this addition. –jensei ---

Hi @jensei and @BlockAnalitica, just making you aware that there was a contract upgrade for OETH a few days ago that strengthens OETH’s security by using Beacon chain merkle proofs. You can find the executed proposal here: [Origin Dapp](https://app.originprotocol.com/#/ogn/governance/1:0x1d3fbd4d129ddd2372ea85c5fa00b2682081c9ec:99121594404373353367959271787303330322964429439529781330823574079193280812345) And the blog post highlighting the upgrades here: [Origin Ether Staking Upgrade](https://www.originprotocol.com/blog/oeth-staking-upgrade?lang=en&category=all&page=1) OETH is the first Ethereum LST to incorporate merkle proofs. ---
