Grant Roscoe

Crescent demos a high-yield treasury product for businesses — live in production V1, newly serving its first publicly traded customer, backed by USDC over-collateralized lending desks with zero exposure to Terra/Luna or Celsius and $30B of originations through its partners. The dashboard compounds interest every second, breaks earnings down by lifetime/year/month, and exposes admin controls for teams (plus easy switching between accredited individual and multiple business accounts, appealing to investment advisors). Because Crescent bridges fiat to USDC to lending desks, it natively supports wire and USDC deposits (ACH via Plaid coming soon) — the demo wires USDC from MetaMask into a Crescent account. Yield is accrued fungibly 1:1 in USDC/dollars at a ~4% sustainable rate. Despite looking like fixed income, Crescent accounts are fully liquid: next-day withdrawals initiate a wire, with Crescent pulling from fully-liquid lending pools, converting USDC to cash, and using bank credit lines to guarantee next-day settlement at zero fees. The roadmap is a yield marketplace: traditional cash sweeps, Treasury/mutual-fund products, and crypto yields — Crescent as the composable middle layer between businesses and yield sources.

Koji Murase

Koji, PM at Modern Treasury, walks through Modern Treasury Ledgers — a managed double-entry ledger API for fintechs like Revolut and Marqeta, marketplaces like ClassPass and Outdoorsy, and anyone building money-movement apps. The demo builds out "BillFold," a sample digital wallet, and walks through the patterns Modern Treasury has seen in production: custom ISO currencies (including USDC with a six-digit exponent for stablecoin-native apps), pending-vs-posted states for in-flight payments, immutable pending transactions with full audit trails, combined payment-plus-ledger API calls, and optimistic locking for just-in-time card funding flows alongside card issuers like Lithic and Marqeta. The closing pattern — purely in-ledger transactions between user accounts — makes user-to-user transfers essentially instant without ever touching an external rail.

Matt Marcus

Matt Marcus, co-founder of Modern Treasury, walks through the Modern Treasury payment operations platform and demos real-time payments (RTP) over The Clearing House's rails. Modern Treasury is a third-party service provider that deliberately stays out of the flow of funds — one API and dashboard connecting into roughly a dozen corporate banks from JPMorgan Chase and Wells Fargo down to niche partners, across ACH, wires, EFT in Canada, Bacs in the UK, and proprietary formats like Silvergate's SEN. The demo races a $1 RTP payment to Matt's Chase and Bank of America accounts via the Payment Orders API, walks through the Postman call (amounts in cents, JPMorgan Chase as the originating bank, credit-only, $100k cap, no returns, synchronous success or failure), and closes with the Modern Treasury "dollar demo," where every viewer can pay themselves a real $1 over RTP if their bank supports receiving it.
