To maximize yield and avoid early capping: * Fund each validator with enough ETH to compound to 2048 ETH over your intended time horizon. * Overfunding leaves capital idle. * Underfunding means missed rewards. > Execution layer (EL) rewards are unaffected and always go to the withdrawal address. ### Initial stake by time horizon These initial stake amounts are recommended for reaching 2048 ETH per validator at the end of each time horizon. | Time Horizon | Optimal Starting Stake | | ------------ | ---------------------- | | **1 year** | \~1980 ETH | | **2 years** | \~1920 ETH | | **3 years** | \~1870 ETH | | **4 years** | \~1810 ETH | | **5 years** | \~1760 ETH | > These figures are based on daily compounding at an estimated **3.0% Consensus Layer APR**.\ > Execution-layer rewards are not compounded and go directly to the withdrawal address. ### Example: allocating 10,000 ETH To deploy 10,000 ETH using the Pectra strategy, allocate 1920 ETH to each of 5 validators and the remaining 400 ETH to 1 validator. All capital earns rewards from day one, and the larger validators compound toward the 2048 ETH cap. This minimizes the validator count, reducing fees and operational complexity. #### Outcomes at 3.0% CL APR over 2 years | Strategy | Capital deployed at deposit | Idle ETH at deposit | Validator Count | Deposit Fees | Net CL Rewards | CL APY% | | --------------------------------------- | --------------------------- | ------------------- | ------------------------- | ------------- | -------------- | ---------- | | Standard 32-ETH | 9,984 ETH | 16 ETH | 312 | 0.624 ETH | 607.37 ETH | 3.042% | | Standard 32-ETH (w/ manual compounding) | 9,984 ETH | 16 ETH | 330 (312 at deposit) | 0.660 ETH | 614.98 ETH | 3.080% | | **Pectra** | **10,000 ETH** | **0 ETH** | **6** (5 × 1920, 1 × 400) | **0.012 ETH** | **618.14 ETH** | **3.091%** | > EL rewards are not modeled here. They accrue separately and are sent to the withdrawal address under all strategies.\ > The assumed deposit fee is 0.002 ETH per validator. Actual costs may vary slightly with network conditions. > Manual restaking assumes weekly reward withdrawal and monthly validator creation, with rewards starting the day of activation. ## Considerations | Topic | Summary | | ---------------- | --------------------------------------------------------------------------------- | | CL Reward Cap | Rewards accrue only on balances up to 2048 ETH | | Balance Flooring | CL rewards are calculated using the floored validator balance (e.g. 100.99 → 100) | | EL Rewards | Unaffected; routed to withdrawal address | | Idle Capital | ETH above 2048 earns no CL rewards — overfunding is inefficient |
