Idem

What it does

Most stablecoin infra stops at settlement — matching transfers to ledger state is still manual. Idem gives AI agents an MCP server to reconcile transactions, roll back mismatches with compensating transactions, and write HMAC-signed audit trails before execution completes. Self-hosted, open source, running against a real ledger via docker-compose — not a hosted black box.

Idem is a source-available, event-sourced double-entry ledger for cross-border stablecoin payments — unifying fiat and on-chain entries in one model.

Event-sourced. Agentic-first. Fiat and on-chain. The source-available double-entry ledger for cross-border stablecoin payments — with built-in reconciliation, Travel Rule-aware audit trail, and AI agent workflows. Every stablecoin payment creates an accounting obligation. USDC arrives on-chain. Your ledger should know. Most don't — or rely on spreadsheets. Cross-border PSPs spend engineering cycles matching on-chain transfers to internal records. Nobody has automated this correctly. As agentic workflows enter finance, every automated action needs an audit trail, policy guard, and rollback. No existing ledger was built for this. Fiat and on-chain entries in a single unified model. Immutable…from idem.finance

  Hi HN, I forked chromium and built agent-browser-protocol (ABP) after noticing that most browser-agent failures aren’t really about the model misunderstanding the page. Instead, the problem is that the model is reasoning from a stale state. ABP is designed to keep the acting agent synchronized with the browser at every step. After each action (click, type, etc), it freezes JavaScript execution and rendering, then captures the resulting state. It also compiles the notable events that occurred during that action loop, such as navigation, file pickers, permission prompts, alerts, and downloads,…

  Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
