Stonewatch is a browser-based idle strategy game on Robinhood Chain where $SW is earned by playing, not by staking. Every player raises a keep, builds a treasury, barracks, granary and armoury, and musters a garrison — and for every hour those soldiers stand, they mint $SW. The game is server-authoritative: production, costs and balances are settled on the server and only then signed to the chain, so nothing can be altered from the browser. Players deposit $SW to build with it and withdraw what they earn from an on-chain vault using cumulative EIP-712 claim signatures. A daily withdrawal limit, drawn from a decaying emission pool, keeps the reward curve predictable instead of front-loaded. Clans compete for the top ten places, where the highest ranked earn up to a +30% production bonus. Heroes and pets are free and carry no advantage — nothing in the realm can be bought, so a new player and an early one start on the same ground. $SW that players spend in-game on buildings and soldiers is permanently removed from circulation: 20,000,000 tokens, 2% of supply, have been burned so far. Trading happens inside the game itself through an integration with Rovyn, so players never have to leave the keep to buy or sell.
