Technical Briefings

Helgaard of Rehive demos Rehive — a no-code fintech app builder that sits on top of the application layer of the fintech stack (above Plaid, Synapse, Wyre). For marketplaces (Fiverr, Upwork, Uber-style) looking to bring banking into their ecosystem, Rehive ships a pre-integrated ledger, user management, and an extensions framework — plus three UI surfaces (iOS, Android, web, admin dashboard, merchant portal). The demo walks through a US-oriented project using Rehive\'s Wyre integration for on/off-ramps, fiat and crypto custody, and KYC — producing a production-ready PayPal-like app in 5–10 business days. From the admin dashboard, operators define currencies (each backed by Wyre or their own custodial license), add account types, and manage transactions. A mass-send extension uploads a CSV of recipients and triggers a bulk payout through the Rehive API — paying users into their own branded wallet instead of PayPal. The consumer mobile app includes peer-to-peer transfers, QR scan-to-pay, a rewards/cashback engine, a lightweight in-app merchant marketplace, and a Wyre-backed crypto buy flow. Merchants get their own portal to list products, send invoices, and integrate POS — Rehive ends with a white-label option that hands over the source code for further customization.

MoonPay is the on-ramp that lets anyone with a crypto wallet top up in a couple of clicks — or, increasingly, buy an NFT with a credit card without ever touching crypto. The demo opens with the common workflow (found an NFT on OpenSea, not enough ETH on Polygon to buy it), walks through a $30 ETH-on-Polygon top-up with 3D Secure via a UK banking app, and tours buy.moonpay.com — MoonPay supports 100+ cryptocurrencies, 40+ fiat currencies, SEPA across Europe and the UK, and a limited US ACH rollout. For developers, MoonPay ships a configurable widget (iframe or URL) with pre-fillable currency, amount, wallet address, email, language, and brand colors, plus an API key per partner. The closing demo buys an NFT on OpenSea with the MoonPay iframe filter enabled — one saved-card click, 3D Secure, and the NFT is minted to the buyer's wallet with no bridging or gas-fee juggling required.

Ben Rollert, CEO and co-founder of Composer, demos Composer — a trading app that gives retail investors access to systematic investing. Strategies are called "Symphonies" — containers for trading logic and the assets they operate on, much like an ETF is a container for a basket. The demo walks through the strategy library (featured, community, classic), Symphony fact sheets with backtests that actually model slippage and fees (rare in retail products), the visual conditional-logic editor and natural-language descriptions, live editing of conditions and benchmarks, swapping underlying assets, and Composer's fundamental building blocks (weight blocks, assets, filters, conditions) used Lego-style to build recursively nested multi-strategy portfolios like the Dragon Portfolio. Composer supports threshold rebalancing (rebalance only on drift, not calendar) and deploys to real brokerage accounts via Alpaca with fractional market orders.
