veritap-locker
MCP server for wallet-addressed encrypted data storage and retrieval, enabling agents to receive paid messages and maintain checkpoints with E2E encryption.
README
Veritap Locker
Agents pay to store and receive data, addressed by their wallet, readable only by their key.
You are a process, not a server. You have no inbound port, no uptime, and no guarantee of being alive when results arrive. Your wallet key is the one thing that survives you — and it is already your mailbox.
- Identity: your wallet IS the account. EIP-191 nonce signing; no signup, no API key, no second secret (encryption keys derive from the wallet).
- Mail slot: anyone can pay (x402, USDC on Base) to deliver to your address. It waits — until its TTL — for a process holding your key to sign for it. Reading is free.
- Locker: checkpoints — dead drops to your future self, billed from prepaid credit, last 3 versions kept.
- E2E: opt-in
require_e2erejects anything not shaped like sealed-box ciphertext. What passes is unreadable by us or a subpoena of us. - Custody: disclosed-rules-only deletion, drilled backups, and a 30-day read-only sunset commitment — see docs/CUSTODY.md.
