    Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know…

    We built OneCLI because AI agents are being given raw API keys. And it's going about as well as you'd expect. We figured the answer isn't "don't give agents access," it's "give them access without giving them secrets." OneCLI is an open-source gateway that sits between your AI agents and the services they call. You store your real credentials once in OneCLI's encrypted vault, and give your agents placeholder keys. When an agent makes an HTTP call through the proxy, OneCLI matches the request by host/path, verifies the agent should have access, swaps the placeholder for the real…

    I am building a simple donation platform where creators can accept tips in crypto — kind of like “Buy Me a Coffee,” but Web3-native. No signups required for supporters. Just share your donation page and anyone can send MATIC, ETH, or any ERC-20 token directly to your wallet. It’s gas-efficient and built on Polygon. Each creator gets a customizable page with a short URL and optional message board. Everything is non-custodial — you own your keys and your funds.

    Vincent lets users safely grant apps/agents limited, revocable permission to use their wallets. Think “OAuth for crypto actions”: you define scopes (e.g., “rebalance stables on Aave up to $1k/day”), users approve, and your app runs within on-chain guardrails. Non-custodial. Built with Lit Protocol's decentralized programmable signing.

    Hey HN, we’ve been working on a way to simplify authentication with third-party APIs. This started because my co-founder andreterron (https://news.ycombinator.com/user?id=andreterron) and I both built personal dashboards to track different health and productivity metrics, but it’s such an annoying chore to integrate with new APIs. First you read their docs to learn their authentication method, then build and deploy a custom server to receive OAuth callback requests or deal with CORS, register an app with them, then finally you can send the first request to their API. After the…

    Abstract. Token-funded bounties to incentivize competition-style participation in blockchain development projects would result in wider and better allocation of investment, and allow investors to diversify exposure across a field of potentially successful projects. Overall this would increase the rate of progress within development of the blockchain space. We propose a centralised platform for the administration of token-funded bounty driven development projects whereby experts allocate pools of invested capital according to the technical merits of development projects, and investors are…

    I started DCA’ing into BTC many years ago. I kept missing buys, buying emotionally into pumps, and forgetting during chop. So I wrote a simple script that hit an exchange API once a day with a fixed amount. Friends asked to use it, so I generalized it and added a DB to manage multiple users. Why I didn’t use existing tools: Most options I tried were either locked to one exchange or did fixed-amount DCA with naive execution. I wanted multi-exchange support and a way to scale buys during dips and preserve capital during rips. I also kept running into inconsistent API rate limits and…
