Switch models, switch apps, start a new chat — your context resets every time. Arca gives every agent one shared memory, encrypted to your wallet on , that you actually own.
why arca
Most AI memory lives in someone else's database — they can read it, lose it, or lock you out. Arca encrypts your memory to your wallet and stores it on , so it's portable across every agent and can't be taken from you.
Next: operator-blind — the service runs inside a TEE so not even the host can read your key or memory. Proven feasible on testnet — not live yet.
Encrypted to your wallet and stored on — at rest it's ciphertext only you can open. Recoverable with your wallet alone; no one can rug it.
Save in your terminal, recall in your browser. Any MCP client — CLI, web, or IDE — reads and writes the same memory.
Each agent connects with its own credential. If one is compromised, cut just that one — the rest keep working.
You sign once; Arca derives your encryption key from that signature — never your private key, and it's never stored at rest.
