Part III - Programmable, Usage‑Constrained Credit (Cross‑Chain Solvers and Beyond)

The final part of the series develops a concrete architecture for usage‑constrained credit in crosschain intent fulfillment, then generalizes it to other closed‑loop loans.

Part II - Instant vs. Guaranteed Settlement, Perps, Factoring, and Usage‑Constrained Credit

Part II - Instant vs. Guaranteed Settlement, Perps, Factoring, and Usage‑Constrained Credit

While we wait for payment, how do we move value safely? For the answer to this, and other questions on credit mechanisms and guarantees, read Part II of our Beyond Loans series.

Beyond Loans — Credit as Price, Collateral, and Code: Part I

Beyond Loans — Credit as Price, Collateral, and Code: Part I

The invisible thread is credit—sometimes explicit, sometimes implicit, sometimes just the promise that when needed, there is cash in the room. This series is about that thread: how we price it, how we secure it, and how code is changing what “settlement” even means.

Building Economic Trust in Solver-Based Networks – Part 3: Reclaiming Efficient Markets

This article is based on the talk ‘Rethinking Competition in Solver-Based Networks’ given at Protocol Berg in Berlin June 13th 2025. (Watch it here) In Part 2, we looked under the hood of real-world solver networks like CoW Protocol and Across. What we found was clear: * A handful of solvers

Building Economic Trust in Solver-Based Networks – Part 2: The State of Competition

This post explores how today's competition models in solver-based protocols are evolving — and in some cases, replicating the same centralization dynamics we hoped to escape.
