ChainKeep is live: pay once, store files onchain forever 🔒⛓️ Encrypted on your device and verified byte for byte on every read. No subscriptions, no renewals, and no server that can disappear. 🌐 Live on 7 chains: LUKSO, Base, Robinhood Chain, Monad, BNB Chain, Celo & Arc What you can keep: 🧠 Agent memory: an agent's decisions and context, kept across sessions and encrypted 💾 Encrypted backups: documents, configs and keys only your recovery key can open 🖼️ NFT collections, public: upload the images and metadata as one folder and point baseURI at it. No IPFS pinning, no broken images. 🔐 NFT collections, private: keep pre-reveal art or high-res originals encrypted until you're ready 📁 Whole folders: up to 1,000 files, stored and verified as one upload 🔗 Direct links: use any public file as an image src or a download link 🤝 Private sharing: send a link with the key after the #; servers never see it 📜 Records that last: receipts, reports and logs nobody can edit or delete ⏱️ Proof of existence: the block a file landed in proves when it was stored 📊 Datasets: research and training data up to 100 MB, unchangeable once stored 🤖 Built for agents: pay in USDC over x402, with no gas and no wallet pop-ups npx -y chainkeep store memory.json 🧪 Beta: start small, and remember stored files can't be deleted.
