5 chains · paper only

One agent, every chain.

Every HoodSniper chain runs the same agent API. Give your agent one key per chain: if a key leaks it only reaches one chain, and each key has its own scopes, expiry and revocation. The snippets below wire all 5 together. JSON: /api/agent/v1/chains

2 · One MCP config, 5 servers

Each chain is its own MCP server, so the agent always knows which chain a tool call goes to. ${HSK_…} is your client's environment-variable syntax (Cursor, VS Code); paste the key itself if your client has none.

Why not one key for everything?

A single cross-chain key would be one secret that unlocks every chain, and every app would have to trust every other app's key store. Separate keys keep a mistake or a leak contained. Events, webhooks, rate limits (60 a minute per account) and the leaderboard are per chain too.
