Nice work. I would take a look at x402 to accept payments directly with stablecoins and goes directly to sellers wallet. Easy to do. Most landing domain sucks.
the main difference is architecture: shardium splits the secret (shamir) so the server never holds the full data, whereas vaultwarden holds the full encrypted vault.
also the "grandma factor": getting non-tech family to setup a vaultwarden account was friction. this is just "find paper in drawer, scan qr".
100%. i actually use it for my gpg keys too. i need to make that clearer on the landing page so it doesn't look like a "crypto-only" tool. recovering ssh/fido2 backups is a huge use case. thanks for the feedback
running 4-of-2 definitely removes the service dependency.
you highlighted exactly the "bug" i wanted to patch though: the collusion risk. if beneficiary A and B have a beer together, you get rugged.
the "live service" here acts purely as a time-lock. beneficiaries can't collude to rob you today because the 3rd shard isn't released until the dead man's switch actually triggers. it protects you from your own friends.
langgraph’s killer for llm-savvy teams needing complex, stateful workflows, think multi-agent systems or cyclic graphs. it’s faster than custom pipelines, with langsmith debugging and one-click scaling. but it’s steep to learn, and debugging multi-agent setups can suck if state’s messy. langchain’s better for simple, linear tasks; langgraph’s for intricate control. autogen’s easier but less precise; crewai’s rigid. langgraph’s your pick for dynamic, production-ready projects.
