# Steledger

Connects AI agents to the Emercoin blockchain to persist identity and memory records. Useful when you need durable, decentralized state tracking across agent sessions.

## What it does

Steledger functions as an MCP client over the HTTP API of the edge gateway. It enables an agent to interact directly with Emercoin: storing content hashes via `store_memory`, registering identities with `register_identity`, and reading NVS entries via `read_record`. When multiple entries need to be recorded together, `store_memory_batch` writes them in a single transaction.

Authentication integrates with GitHub through the device authorization flow. Calling `login` initiates the process and returns a code for the user, while `login_poll` waits for confirmation and caches the resulting JWT. In automated pipelines or local testing, `login_with_token` accepts an existing GitHub token directly.

Write operations stay locked without credentials. If `GATEWAY_JWT` is not passed at startup, the agent must complete the interactive login sequence before submitting records. The target service address is configured through `GATEWAY_URL`, which points to `http://localhost:8000` by default.

## Requirements
- Needs: Docker
- Remote server: `https://api.steledger.com/mcp`
- Environment variables: `GATEWAY_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- anchor AI agent identity to an Emercoin blockchain address
- write content hashes and metadata into decentralized memory
- commit a batch of memory records in one atomic transaction
- read existing NVS records by name without credentials
- authenticate the agent session using the GitHub device flow

## Example prompts
- Start GitHub device login and output the code for authentication
- Register agent identity for address EMC_KEY with project metadata
- Retrieve the memory entry named session_checkpoint from NVS
