Ethereum's draft 2,048 ETH rule could lock rewards longer

Ethereum is considering EIP-8148, a draft rule that would let compounding validators choose a threshold between 32 ETH and the current 2,048 ETH default. Rewards above a valid custom threshold would become eligible for Ethereum's automatic withdrawal sweep. The 2,048 ETH default could keep user rewards locked longer than expected. Customer payout timing remains unresolved. An Aug. 20 edit lowered the proposal's minimum custom threshold from 33 ETH to 32 ETH. The edit also added a way to set the initial threshold when a new validator is created. Existing compounding validators would start at the default and could later submit a valid change. An absent or invalid custom value would default to 2,048 ETH. A post-creation request could not set the threshold below the validator's current balance. A creating deposit with a threshold below the deposited amount would be ignored and would use the default. Validators seeking a lower level would first need to use the standard partial-withdrawal process. Principal withdrawals would continue through Ethereum's existing partial-withdrawal or full-exit paths. Ordered withdrawal processing would follow those paths. Legacy withdrawal credentials have a 32 ETH effective-balance cap. Balances above 32 ETH under those credentials are periodically swept to the withdrawal address. Compounding validators can increase their effective balance in 1 ETH increments. Their effective balance can reach 2,048 ETH. Access to ETH below that level currently requires a manually requested partial withdrawal. A July 28 Pectrified snapshot counted 16,926 active compounding validators. They represented 1.91% of active validators. They held 13.36 million ETH. That amount represented 32.43% of active stake. A live Validator Queue snapshot on Aug. 25 showed 160 ETH in the exit queue. The snapshot estimated a four-minute exit-queue wait. The same dashboard estimated a 7.8-day network-wide automatic sweep cycle. The exit queue covers validators leaving the active set. The sweep cycle covers eligible validator balances. The cited data does not provide a separate public backlog for partial-withdrawal requests. Lido's documentation says staking and execution-layer rewards feed its pooled accounting. Lido updates stETH holder balances through oracle-driven rebases. Coinbase Prime says rewards on Pectra-enabled validators compound. Coinbase Prime says customers can claim those rewards through its existing partial-withdrawal process under stated conditions. Threshold policies remain unresolved for both services. A lower threshold could make ETH leave a validator sooner without determining when a service credits, rebases, or releases value to users. EIP-8148 remained marked Draft on Aug. 25. Forkcast listed the proposal for Hegotá. The related consensus-spec change was merged on Aug. 24. Fork placement, activation timing, and final implementation remain pending. Ethereum mainnet continues to use the existing rules.
