Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

Hey Everyone! Avi and I (in the current YC S25 Batch) noticed how fragmented crypto compliance is with rules changing constantly, vary by region, and force developers and legal teams into a scramble. So we hacked together a prototype framework that generates a “guardrail” smart contract which: - Hooks into your KYC provider - Enforces rules defined a simple compliance.yaml file - Automatically blocks users you can't legally serve When regulations shift (new blocked country, updated KYC threshold, etc.), just update your YAML and redeploy with no smart contract rewrites. Audit prep also…

Hi HN, We’ve been working on NativeSwap.io, a low-cost decentralized cross-chain swap platform. It lets users swap native assets (e.g. BTC DOGE) directly, without using wrapped tokens or centralized bridges. Our goal is to make cross-chain swaps cheaper, simpler, and safer. The platform is fully non-custodial and supports both regular and streaming swaps. Under the hood, it leverages liquidity from protocols like ThorChain and Maya Protocol. Currently, We support the following blockchains: - Bitcoin - Ethereum - BNB Smart Chain - Ripple - Dogecoin - Litecoin - Bitcoin Cash - Zcash - Base -…
