Raise a keep.
Raid your neighbours.
CryptoCastle is a pixel-art base-building game in the shape of Clash of Clans, settled on Solana. You mine a token called castlecoin, spend it raising your castle, and send your army against other players' bases to take theirs.
Five Town Hall levels, from a Timber Hall to a Gilded Citadel. Real players, real bases, and a coin you can withdraw to your own wallet whenever you like.
Costs a one-off 5 USDC to create a castle. Nothing after that.
How it works
1 · Mine
Castlecoin mines produce coins over time. You collect them by hand, and your vaults set how much you can hold before a mine backs up and stops.
2 · Build
Coins buy mines, vaults, barracks, cannons, archer towers, trebuchets and walls. Your Town Hall level caps how many of each you may own and how far you may upgrade them.
3 · Raid
Scout a rival base, deploy your army and take what you can carry. Matchmaking looks for players at your own Town Hall level first, then one either side.
4 · Withdraw
Coins in your vault can be withdrawn to your own Solana wallet 24 hours after they land. There is no withdrawal fee.
What raiding can cost you
Being raided is meant to sting without ending your run. A successful attacker can take at most 25% of what is in your vaults, and coins already collected into a mine's hopper count towards that. Seventy per cent of the loot comes from the resource buildings the attacker actually destroys, the rest from overall damage.
After you are raided you get a 16-hour shield during which nobody may attack you. New castles are protected for their first 2 hours. Everyone may launch one attack per day. None of this is reversible: coins taken in a raid are gone, and there is no support desk that will put them back.
The coin
Castlecoin (CSTL) is an SPL token on Solana with a fixed supply of 1,000,000,000 and six decimals. It is created on pump.fun, and the mint authority is revoked at creation — no more can ever be made.
200,000,000 — Emission Reserve
Every coin a mine produces is paid out of this reserve. It is finite, which is why creating a castle costs money: a thousand scripted accounts would drain it and leave nothing worth playing for.
800,000,000 — Open market
Sold on the pump.fun bonding curve. The game has no claim on it and no ability to mint more.
Burning
Coins you spend on buildings and upgrades are taken out of circulation. 80% of every burn returns to the Emission Reserve so mines keep paying, and the remaining 20% is destroyed on-chain for good. You can watch the token's total supply fall as people play.
Land
Four maps — Greenfield, Frostbound Tundra, Ashen Wastes and the Heights of Olympus. Greenfield is free; the others cost 10, 20 and 100 USDC. They are purely cosmetic. They change nothing about how a base plays, mines or defends, and they are never bought with castlecoins.
