Compass Labs Technical Briefing
Published April 14, 2026
Supported by Brale , The Stable Coin Company and Refract Ventures
Overview
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.
0:00 Introduction to Compass Labs
Elisabeth Duijnstee introduces Compass Labs — the DeFi layer for fintechs and neobanks. One API for stablecoin yield, crypto-backed loans, and tokenized stocks, so platforms can ship DeFi products in a day instead of building protocol-by-protocol integrations.
0:49 From physics to DeFi infrastructure
Background: a PhD in physics at Oxford, a London fund role, and the move into crypto trading. The thesis: better finance runs on crypto rails, but building on-chain is painful — protocols are integrated one by one, and shipping a second product tends to break the first.
1:51 Compass Studio and the product suite
Tour of studio.compasslabs.ai and the API catalog at api.compasslabs.ai. Four product lines: DeFi savings, portfolio management, credit (crypto-backed loans), and public markets (tokenized stocks), all behind a single set of endpoints.
2:54 Configuring a DeFi savings account
Live build of a white-label yield product on Base. Select chains and tokens, then filter the ERC-4626 vault universe (Morpho, Pendle, and more) by minimum TVL and asset to curate the markets surfaced to end users — including a fixed-rate Pendle option.
4:16 First deposit into a Gauntlet USDC vault
A non-custodial $5 deposit into the Gauntlet USDC Prime vault, confirmed on BaseScan. Compass returns transaction payloads — custody stays with the integrator's wallet layer (any wallet, embedded or otherwise).
5:06 Positions, reporting, and swap-and-deposit
Read balances, positions, realized and unrealized P&L, and transaction history via the Compass API — useful for end-user reporting. ETH is swapped and deposited into a USDC-denominated market in a single call.
5:56 White-label UI and copy-paste shipping
Theme the widget for dark or light mode, pick brand colors, and copy-paste the generated code into your app. Gas sponsorship, monetization, and bridging are abstracted behind the API rather than re-implemented per integrator.
7:15 Segregated accounts and crypto-backed loans
Per-product sub-accounts keep fund flows isolated across savings, credit, and markets without intermingling balances. Quick look at the credit product: deposit BTC, borrow USDC, inspect the net interest rate, and ship.
8:03 LLM docs and a DeFi risk dashboard
Compass exposes LLM-oriented docs that pair well with Claude Code and other coding assistants. Demo of a risk dashboard built that way — showing per-wallet exposure across underlying markets and overlap between Morpho and Pendle vaults.
9:24 Free API key and call to action
Free API keys at api.compasslabs.ai with generous limits for building an MVP, plus hands-on support from the Compass team for integrators shipping DeFi products.
