The Ethereum Foundation’s privacy team, now rebranded as Privacy Stewards of Ethereum (PSE), has released a roadmap to enable end-to-end onchain privacy via private writes, reads, and proving. It includes a Layer 2 design, PlasmaFold, supporting private transfers, with a

𝐔𝐒𝐃𝐦 𝐚𝐧𝐝 𝐌𝐞𝐠𝐚𝐄𝐓𝐇: 𝐖𝐡𝐚𝐭 𝐈𝐬 𝐓𝐡𝐞 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞? TL;DR USDm is issued on Ethena’s USDtb rails and backed primarily by tokenized U.S. Treasuries (BlackRock BUIDL via Securitize). The reserve yield is programmatically routed to cover MegaETH sequencer OPEX, so gas can be priced at cost while keeping fees stable as throughput scales. Integration is deep across wallets, paymasters, and apps on @megaeth_labs. USDT0 and cUSD remain first-class assets. ------ 📌 𝐓𝐡𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐒𝐭𝐚𝐜𝐤 1. Economic layer → Reserves: USDm v1 uses the USDtb reserve model: ~target 90% BUIDL (tokenized short-duration Treasuries) held via Securitize, plus liquid stables for redemptions. It has 24/7 atomic swaps between USDtb and BUIDL, which tighten settlement and transparency. → Yield source: BUIDL’s T-bill yield accrues on reserves such that yield is earmarked to fund sequencer costs on MegaETH. 2. Issuance → Issuer rails: Ethena provides the stablecoin stack (contracts, treasury operations, reserve disclosures). USDm adapts its collateral mix over time. → Compliance/custody: USDtb has a clear path toward compliance (GENIUS Act notes with Anchorage) and institutional integrations. 3. Execution & Settlement → Chain integration: MegaETH bakes USDm into paymasters, wallets, DEX routes, oracles, and app services. Gas can be paid cheaply while USDT0 and cUSD remain supported routes. → Sequencer OPEX link: Reserve yield flows to a funding sink that offsets the L2’s sequencer costs. This inverts the usual fee-margin model and lets MegaETH run the sequencer at cost. 📌 𝐌𝐞𝐜𝐡𝐚𝐧𝐢𝐜𝐬 1. Reserve backing and mint/redeem → Backing: USDm v1 is economically equivalent to USDtb units sitting on BUIDL, with a liquidity sleeve in stablecoins to support redemptions. Reserve composition is adjustable by policy. → Mint/redeem path: On issuance, assets routed through venues become USDtb exposure. Atomic swap rails allow moving between USDtb and BUIDL 24/7, improving settlement finality and liquidity management. Redemptions unwind the path in reverse. 2. Yield routing to L2 costs • Computation: Net portfolio yield of reserves → USDm Reserve Yield Account → periodic transfer to Sequencer OPEX bucket. Gas prices can then track data and compute costs rather than a markup. Why? As data costs change and throughput scales, fee volatility doesn’t need to be pushed to users to protect L2 margins. 3. Onchain, Ethena’s USDtb/USDe contracts provide ERC-20 interfaces and policy hooks. MegaETH then integrates paymaster support and router/oracle paths for USDm. ------ 📌 𝐈𝐧𝐭𝐨 𝐌𝐞𝐠𝐚𝐄𝐓𝐇 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 MegaETH’s execution architecture is heterogeneous: ✔️ One active sequencer ✔️ Full nodes, ✔️ Replica nodes (apply diffs without re-execution), and ✔️ Prover nodes. It targets ~10 ms latency and 100k+ TPS, secured by Ethereum and paired with EigenDA for data availability. The USDm design complements this by de-linking fee revenue from user surcharges and pinning it to reserve yield. ------ 📌 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 𝐑𝐨𝐥𝐞𝐬 1. MegaETH (MegaLabs): → Integrates USDm into wallets, paymasters, gas accounting, indexers, and routing. → Maintains a fee policy that prices gas at cost, funded by USDm yield. → Preserves competing stablecoin routes (USDT0, cUSD) to avoid lock-in. 2. Ethena → Operates the stablecoin stack and reserve policy for USDtb. Provides issuance, risk, disclosures, and protocol governance. 3. Securitize / BlackRock → BUIDL custody/transfer, investor compliance, and tokenized fund operations that underpin USDtb’s reserve quality and liquidity rails. ------ 📌 𝐀𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞𝐬 → Fee Stability at Scale: Yield covers sequencer OPEX as usage rises, so MegaETH avoids hiking fees to defend margins. → Institutional Reserve quality: BUIDL and Securitize add a clear operational framework and integrations across CeFi/DeFi. → Adaptable Reserve Policy: Ethena’s stack allows shifting collateral mix (e.g., to include USDe exposure) if conditions change. ------ 📌 𝐑𝐢𝐬𝐤𝐬 𝐚𝐧𝐝 𝐎𝐩𝐞𝐧 𝐐𝐮𝐞𝐬𝐭𝐢𝐨𝐧𝐬 (𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 𝐚𝐧𝐝 𝐏𝐨𝐥𝐢𝐜𝐲) → Reserve yield vs. OPEX mismatch: If short-rate yields compress or DA costs rise, yield may not fully cover sequencer costs, forcing policy changes or supplemental revenue. → Counterparty/compliance dependencies: Reliance on BUIDL/Securitize and associated investor frameworks introduces offchain and regulatory dependencies. → Smart-contract surface: USDtb, paymasters, routers, and OPEX routing add integration risk. I expect audits and management. → Liquidity pathing: Deep liquidity for USDT0 and cUSD will coexist. This means USDm needs competitive venue support to minimize routing slippage in practice. → Governance clarity: Who will manage reserve-mix changes for USDm, and how OPEX distributions are parameterized? This matters a lot to users and integrators. You can also check a simplified explanation of USDm, written by @St1t3h:
