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:

Cap Stablecoin Protocol Officially Launches, cUSD Minting Now Open

Now tracking @capmoney_'s cUSD coin on our Stablecoins Dashboard Users deposit reserve assets to mint cUSD at oracle value. cUSD's reserve is backed by stablecoins such as USDC, USDT, pyUSD, BUIDL, and BENJI

Monad, a Layer-1 blockchain built for high performance and compatible with the Ethereum Virtual Machine (EVM), has officially joined the Chainlink SCALE program. Through the partnership, Monad will bring Chainlink’s oracle services to its testnet, including data feeds, data streams, and the CCIP cross-chain protocol. This means developers building on Monad will have access to more accurate and reliable market data, without having to rely on third parties. Chainlink on Monad mainnet day 1 @chainlink will unlock data feeds, data streams and CCIP for developers nads 🤝 marines pic.twitter.com/FGXDVHcICU — Monad ⨀ (@monad_xyz) April 22, 2025 If you’ve ever tried building financial applications on a blockchain, you know how crucial stable, un-tamperable data is. That’s where Chainlink comes in. By providing tamper-proof pricing and market insights, this integration can boost user trust and pave the way for wider adoption. Furthermore, Chainlink Data Streams enable data delivery at low costs and with reduced latency. For DeFi projects that need speed and efficiency, this could be the solution they’ve been looking for. CCIP is also interesting, because it allows cross-chain token transfers with specific instructions on the destination blockchain—like sending money while telling you directly what to use it for. On the other hand, CNF also previously reported that CAP had already used Chainlink oracles on Ethereum to ensure that the cUSD price remains transparent and cannot be manipulated. CAP’s move is a real example of how Chainlink can directly strengthen the credibility of DeFi projects. Chainlink itself is hot. In the past month, more than $120 million in LINK tokens have been withdrawn from exchanges, most likely by large investors who are accumulating. Not only that, Chainlink has also started communicating with regulators. In the past few days, the Chainlink Labs team has had discussions with the SEC to discuss token classification and project transparency. Sergey Nazarov, the CEO, even explained how blockchain can help in asset management. Meanwhile, LINK’s adoption in the mainstream market is also expanding. PayPal recently added Chainlink and Solana to the list of cryptos supported on its platform. This means PayPal users can now buy, hold, and sell LINK directly. And for those curious about Chainlink’s long-term plans, save the date: SmartCon will return to New York on November 4–5, 2025. It will be held at the Metropolitan Pavilion, and is expected to be a major event for Web3 and DeFi players from around the world. At the time of writing, LINK was trading at around $14.61, up 11.83% in the past 24 hours, pushing its market cap past the $9 billion mark.
