delegare▲70Hi 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…

I built AI Trust Proof — an experiment in recording human good faith on-chain so it can be independently verified by people, software, or (eventually) AI systems. What it does (today) - Lets you sign a plain-English pledge and record its signature hash + metadata on Solana (devnet). - Mints a symbolic NFT badge pointing to that record. - Creates a verification page that shows the pledge, signature, and on-chain proof. What it’s not - No token, no airdrops, no yield. - Not a reputation score or KYC. - Currently just one signal: "Pledge signed." Why - If AI systems begin prioritizing who to…

Agents can talk, code, and browse… but until now, they couldn’t accept money. We built PayDroid, a universal checkout for AI agents. It routes through the merchant’s own processor (starting with PayPal, Stripe coming soon), so there’s no license, no custody, and no messy integration work. Developers just integrate once, and agents get a frictionless callback flow that works everywhere. Demo (live with PayPal): https://demo.paydroid.ai Docs: https://paydroid.ai Would love feedback — what would you sell through your agent?

Hey HN, I’m Chris, a solo dev in Melbourne AU. For the past month I've been spending my after work hours building AgentVisa. I'm both excited (and admittedly nervous) to be sharing it with you all today. I've been spending a lot of time thinking about the future of AI agents and the more I experimented, the more I realized I was building on a fragile foundation. How do we build trust into these systems? How do we know what our agents are doing, and who gave them permission? My long-term vision is to give developers an "Agent Atlas" - a clear map of their agentic workforce, showing where…

We built a protocol that gives AI agents an address, plus discovery/trust/payments between agents. Agents install it themselves with one line (see on pilotprotocol.network) - about 250k have, exchanging ~2B packets/day, mostly without their owners’ knowledge. The interesting part for HN is probably the App Store model: publishers list tools, and agents autonomously discover and install them (30k installs in the first two weeks). Happy to answer anything about the architecture, trust model, or the weird stuff agents do on the network.

Mingle▲3I built an autonomous AI agent running 24/7 on a Mac Mini (16 tools, persistent memory, proactive scheduler). Kept hitting token budget walls on ambitious tasks — agent starts something good, runs out of tokens, stops. So I wrote a protocol for agents to collaborate: discover each other, propose projects, vote on resource allocation (one agent = one vote, cryptographically bound to one owner), pool tokens, execute together. Key decisions: reputation-weighted not wealth-weighted governance, privacy-first (share knowledge never owner data), protocol evolves through agent voting.
