ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

  • Litecoin Surpasses Bitcoin as the Most Used Cryptocurrency on BitPay Payment Platform
    Bitcoin users abandoned bitpay about six years ago during the blocksize wars, because they joined the bcash attack. Now anyone that wants to accept bitcoin payments, and especiallly through lightning, uses the open-source btcpay. Source: over 2 years ago
  • Kagi now accepts PayPal, EUR and Bitcoin payments
    > It was also an interesting learning experience, implementing it was much harder than we anticipated and I hope others in the same position can benefit from our learnings. Well done, never mind that guy, he clearly has an axe to grind and doesn't seem to grasp very much other than his out of touch talking points: did you look into using BTCPAY [0] server? Things are still not as easy as they should, but have... - Source: Hacker News / almost 3 years ago
  • Which plugin is the best to accept crypto payments?
    Game changer for us is BTCPay Server since a big point of crypto is removing banks/middlemen. Rock solid and bitcoin goes directly to our wallet that we control the private keys for. No Coinbase. No Bitpay. Just actual bitcoin. Highly recommended. Source: about 3 years ago
  • Doubts regarding Lightning API by Jock Dorsey through Nodeless
    Since the transaction which would be running are not going to be that large of a quantities where each and every % matters, I think it would be safer to go with something like nodeless as referred. For some larger operations https://btcpayserver.org/ would be somewhat better. Thank you for the help! Source: about 3 years ago

    Did you teach them about lightning? BTCPay Server? Source: about 3 years ago
