All ETH Strategy contracts are deployed on Ethereum mainnet. ESPN options execution operates on the Derive chain. ### Ethereum Mainnet — EARN | Token | Address | | ----- | --------------------------------------------------------------------------------------------------------------------- | | EARN | [0x106E54F413180953C5D251bcc3d82122b9c63dAf](https://etherscan.io/address/0x106E54F413180953C5D251bcc3d82122b9c63dAf) | | sEARN | [0x2B5ab0a6CAb343edeeF46A2e90F23460bc852938](https://etherscan.io/address/0x2B5ab0a6CAb343edeeF46A2e90F23460bc852938) | | USDS | [0xdC035D45d973E3EC169d2276DDab16f1e407384F](https://etherscan.io/address/0xdC035D45d973E3EC169d2276DDab16f1e407384F) | #### Staked EARN (sEARN) sEARN is the staking contract for EARN (`StakedStrat`). It is the only contract that pays EARN yield: holders stake EARN and receive sEARN 1:1 as a non-transferable position token, and USDS rewards stream to stakers from it. | Field | Value | | ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | | Address | [0x2B5ab0a6CAb343edeeF46A2e90F23460bc852938](https://etherscan.io/address/0x2B5ab0a6CAb343edeeF46A2e90F23460bc852938) | | Token name / symbol | `Staked EARN` / `sEARN`, 18 decimals, non-transferable | | Staked token | EARN (`0x106E54F413180953C5D251bcc3d82122b9c63dAf`) | | Reward token | USDS (`0xdC035D45d973E3EC169d2276DDab16f1e407384F`) | | Reward stream | 28 days per funding (`REWARD_DURATION = 2419200`) | | Deployed | 24 September 2026, block 26045596, tx [0xd4417ef5…2ac13c](https://etherscan.io/tx/0xd4417ef5834dc28eaf5fed85fafce29c9dac3815736467ef7e7aec79cf2ac13c) | | Circuit breaker | [TripwireController](https://etherscan.io/address/0x328aED8F7a01f45A959c187F3cb97eC508064854) `0x328aED8F7a01f45A959c187F3cb97eC508064854` | {% hint style="warning" %} An earlier deployment of the same contract exists at `0xD9d1eFaCF470a57E8936D8Cc46665b8A51c21215`. It was never put into service, holds no stake and pays no rewards. Integrators and verifiers should use `0x2B5a…2938` only. {% endhint %} #### EARN/USDS Liquidity Pool The EARN/USDS pool uses Uniswap v4 on Ethereum mainnet. It is identified by a pool ID within the shared PoolManager, rather than a separate pool contract address. **Pool ID:** `0x0cfa37ad329ca46b06fc4e45f3fb2f32fc6b210a66cf6eb1311b614b2fb2596f` **Fee:** 0.30% (3000) · **Tick spacing:** 60 · **Hook:** None (zero address). | Contract | Purpose | Address | | --------------- | ----------------------------- | --------------------------------------------------------------------------------------------------------------------- | | PoolManager | Holds the pool and its tokens | [0x000000000004444c5dc75cB358380D2e3dE08A90](https://etherscan.io/address/0x000000000004444c5dc75cB358380D2e3dE08A90) | | PositionManager | LP position NFTs | [0xbD216513d74C8cf14cf4747E6AaA6420FF64ee9e](https://etherscan.io/address/0xbD216513d74C8cf14cf4747E6AaA6420FF64ee9e) | | StateView | Read price and liquidity | [0x7fFE42C4a5DEeA5b0feC41C94C136Cf115597227](https://etherscan.io/address/0x7fFE42C4a5DEeA5b0feC41C94C136Cf115597227) | #### Protocol LP Positions The Safe's LP position NFT IDs are **414334** (full range) and **414335** (bid wall). These identify positions in the PositionManager, not separate pool contracts. *** ## Ethereum Mainnet — ETH Strategy Core | Contract | Type | Address | | --------------------------------------------- | -------------- | --------------------------------------------------------------------------------------------------------------------- | | **STRAT Token** (`StratToken`) | ERC-20 | [0x14cF922aa1512Adfc34409b63e18D391e4a86A2f](https://etherscan.io/address/0x14cF922aa1512Adfc34409b63e18D391e4a86A2f) | | **Legacy STRAT Option** (`StratOption`) | ERC-721 | [0xe1e9093365545e11Cb02c36B2688E17B4Dc447FC](https://etherscan.io/address/0xe1e9093365545e11Cb02c36B2688E17B4Dc447FC) | | esETH Token (esETH) | ERC-20 | [0xE7A2F9b5fE8a3bb067c15ad08644d96b9dfDf9cb](https://etherscan.io/address/0xE7A2F9b5fE8a3bb067c15ad08644d96b9dfDf9cb) | | CDT (CdtToken) | ERC-20 | [0xD4598307B5507A2b04d0502FCC9b68bbcA9275F3](https://etherscan.io/address/0xD4598307B5507A2b04d0502FCC9b68bbcA9275F3) | | Convertible Note (EthStrategyConvertibleNote) | ERC-721 | [0x3B4eC3deCfEC8E2260be01018f6fE04741A8aa56](https://etherscan.io/address/0x3B4eC3deCfEC8E2260be01018f6fE04741A8aa56) | | desETH Token (DesEthToken) | ERC-20 | [0x2e65e2Fa50E8338d2CC81821D15364cF9516145f](https://etherscan.io/address/0x2e65e2Fa50E8338d2CC81821D15364cF9516145f) | | Legacy Staked STRAT | ERC-4626 Vault | [0xD6664390E0485Cd609d4D04b430e84e945a51994](https://etherscan.io/address/0xD6664390E0485Cd609d4D04b430e84e945a51994) | All core contracts are verified on Etherscan. `StratToken` extends `ERC20Permit` (EIP-2612) with authorized minting and burning. `StratOption` is the legacy options contract.

Each sub-multisig (Liquidity, Staking, Puttable Warrant, Perpetual Note) inherits from the main ETH Strategy Multisig, distributing operational control across functional domains while maintaining a unified governance structure.

No deployment address or confirmed launch date is listed here. See [Roadmap](/introduction/roadmap.md). Core protocol and EARN audits have been reported complete, but reports and reviewed-version mappings are not publicly linked as of 19 October 2026. See [Audits](/security-and-risk/audits.md) for publication status and the separate legacy ESPN report. *** ## Compiler & Verification All ETH Strategy contracts are compiled with Solidity v0.8.20 and v0.8.24, verified on Etherscan with exact source match, and use OpenZeppelin's `Ownable2Step` for ownership transfers. Third-party contracts (Uniswap, Arrakis, Socket) use their respective compiler versions.
