How a gated buy works

1. The site checks what the mods require and signs a ticket: wallet, mint, max amount, expiry, identity hash.
2. The transaction carries an Ed25519 check of the ticket, then the router call.
3. The router checks the ticket and the caps, then calls the Meteora swap.
4. The token transfer triggers the rules hook, which checks that the router is the caller and applies every mod enforced by the token.

SDK

import { clients, fetchLaunchState, buildTrade, describeLaunch } from "@gatekeeper/sdk";

const c = clients(connection);
const state = await fetchLaunchState(c, mint);
console.log(describeLaunch(state));            // the mods, in plain English
const tx = await buildTrade(c, state, {
  user, side: "buy", amount, slippageBps: 1000,
  ticket,                                       // when the mods ask for one
});

Community board

Loadouts and stars are memo transactions that also touch the board address, so the board is read from that address's history. A loadout memo starts with charter/loadout/1followed by JSON with a name, a note and the rack in the same format as the studio's share links. A star is charter/star/1followed by the loadout's transaction signature; one star per wallet counts.
