Lightning Memory
This server turns your AI agent into a Lightning-native spender with persistent memory and vendor intelligence. It stores transactions, preferences, and vendor interactions locally in SQLite with FTS5 search, syncs them as NIP-78 events to Nostr relays using BIP-340 keypairs, and exposes 22 MCP tools for querying payment history, checking vendor reputation scores, detecting price anomalies, and enforcing per-vendor budgets. The preflight gate blocks suspicious invoices before you pay them. You can run an L402 gateway so other agents pay sats to query your memory, and discover remote gateways to buy intelligence from the network. Reach for this if you're building autonomous agents that make L402 payments and need spending discipline, vendor trust signals, and cross-session learning without starting from zero every time.

Lightning Memory
Persistent memory for AI agents in the Lightning economy.
The Problem
AI agents spend sats over Lightning via L402 — but they can't remember what they bought. Every session starts from zero. Every vendor is a stranger. Every price is accepted at face value. An agent that paid 500 sats yesterday doesn't know if today's 5,000 sat invoice is a price spike or normal.
The Solution
L1: Bitcoin — settles
L2: Lightning — pays
L3: Lightning Memory — remembers
Lightning Memory gives agents persistent memory, vendor intelligence, and payment safety gates. Agents learn from their spending history, track vendor reputations, detect price anomalies, enforce budgets, and share trust signals with other agents.
Interactive Demo — watch an agent learn, get rugged, and route around bad actors.
