Technical Briefings
Elisabeth Duijnstee
Compass Labs CEO Elisabeth Duijnstee walks through how fintechs and neobanks can embed DeFi products — stablecoin yield, crypto-backed loans, and tokenized stocks — through a single non-custodial API. The briefing includes a live build in Compass Studio of a white-label USDC savings account on Base, a $5 deposit into a Gauntlet USDC Prime vault, and a tour of position reporting, segregated sub-accounts for crypto-backed credit, and an LLM-friendly docs surface designed for coding agents like Claude Code.
Toby Rush
Ideem CEO Toby Rush walks through how modern cryptography can deliver invisible possession-factor authentication for banks, neobanks, and agentic-commerce flows. The briefing covers Ideem's FIDO + multi-party-computation "chip in software" model, device-plus-passkey binding on the same challenge, and a live Android demo of app-to-app bridging where a merchant webview verifies trust with a previously enrolled Yes Bank app via a silent push and an encrypted local channel — with no human in the loop.
Brendan Ryan
Tempo's Brendan Ryan introduces the Machine Payments Protocol (MPP), designed with Stripe as the payment form for AI agents. The briefing shows how MPP rides natively on HTTP request/response flows so agents can make paid API calls without preconfigured API keys or billing relationships, with live demos paying Parallel for web data and unlocking a payment-gated article via HTTP 402 — across Tempo, Stripe, Solana, Bitcoin payment methods, and Visa cards from day one.
