Ethereum builders are facing a structural choice between locking up protocol capital to back payments and relying on trusted broker-style connections, according to a Sept. 8-11 Lido discussion. Commit-Boost contributor Jason Vranek said builders funding protocol-backed payments face costs from idle ETH, failed payload delivery, and offers they would prefer to cancel. At the same time, Titan Builder contributor George said Titan does not plan to open a direct proposer endpoint and expects validators to continue reaching builders through relays that organize auctions and handle publication.
The technical backdrop includes EIP-7732, still under review, which separates a proposer's consensus block from the execution payload. In the proposed design, a builder's signed commitment is included in the consensus block, and the execution payload follows separately. Payments can be collateral-backed by ETH deposited into the protocol, or trusted, meaning the builder promises to pay through another route. Ethereum.org lists Glamsterdam as testing on devnets, with mainnet expected in the fourth quarter of 2026 and no confirmed date. The Ethereum Foundation's Sept. 7 priorities identify fork-choice enforced inclusion lists, or FOCIL, as a Hegota headliner, while Lido contributors are discussing direction ahead of a future DAO vote.
Builders maintaining ETH reserves to secure payments cannot use that capital elsewhere, and exposure to paying without successful delivery may reduce their willingness to commit maximum payments. A trusted arrangement could reduce those costs and leave more room to pay the proposer, although the actual advantage depends on counterparty performance and available amounts. Lido's initial Aug. 22 direction would accept eligible collateral-backed offers broadly while restricting trusted offers to a governance-approved allowlist. Vranek's later response proposed open peer-to-peer offers alongside configured builder or relay endpoints, keeping payment and connectivity choices separate.
Separately, the Office of the Comptroller of the Currency has proposed stablecoin redemption rules that would set an ordinary deadline of two business days after a redemption request. Requests exceeding 10% of outstanding issuance value in 24 hours would automatically extend the period to seven calendar days, unless the OCC determines an earlier redemption can proceed in an orderly, fair, and transparent way. The proposal covers issuer redemption, excludes secondary-market trading, and is aimed at orderly reserve liquidation. As of Sept. 13, it remained on the OCC proposed-issuance list with a March 2 opening and a May 1 comment deadline.
A Sept. 4 Federal Reserve staff analysis separates blockchain payment functionality from conversion into bank dollars and describes redemption timeframes as unsettled. Circle's USDC terms for non-EEA holders require an eligible Circle Mint account for direct redemption and commit to one dollar per USDC subject to fees, but do not guarantee third-party platforms will quote USDC at one dollar. Coinbase's instant cashout guidance describes US customers withdrawing from USD or USDC balances to eligible US bank accounts via Real Time Payments, with a $100,000 per-transaction limit, typically around 30 minutes but up to 24 hours depending on the provider.
The two discussions highlight different parts of crypto market infrastructure: Ethereum's block-building payment design may shift whether builders rely on protocol collateral or trusted relationships, while stablecoin redemption rules could separate issuer settlement from customer-facing conversion. In both cases, choices about collateral, connectivity, and liquidity determine whether promised value is actually available when market participants need it.
