Courier

Welcome to the planetA tiny town, a bag of letters, and a game that lives on Robinhood Chain.

Courier World is a little planet you can walk all the way round. You're its courier: pick up letters at the post office, find the right doors, and chat with the people who live there. Behind the town is an on-chain economy: 3,333 Courier NFTs work out of player-run post offices and earn $STAMP, which trades in a Uniswap pool.

Walking about is free and needs nothing but a browser. A wallet on Robinhood Chain lets you play as your own couriers, run a post office and earn.

PlayingDeliver letters, explore, find the golden stamps.

Deliveries

You start with three letters. The arrow at the top points to the nearest address, and an envelope floats over its door. Walk up to the door to deliver. When the bag is empty, head back to the post office for more.

Places

Golden stamps

Twenty-four golden stamps are hidden round the planet. Some float at arm's height, some only a jump reaches, and a few sit up high: on the hill, the pier, the catwalk and the footbridge. Your count shows in the top bar.

Days pass every 12 minutes, showers roll over now and then, and the town's people wave, chat and go about their day.

Couriers3,333 NFTs with fully on-chain art.

Every courier has a look and a ride, fixed at the reveal by a secret committed before the mint, so nobody could snipe the rare ones. The art is drawn on-chain as a postage stamp: its value shows the courier's delivery power, a badge shows its level, and an ON DUTY postmark appears while it works. Log in with a wallet that holds couriers and you play as one.

The mint is over. Couriers trade on OpenSea, with a 5% royalty on sales. A courier on duty can't be transferred until you take it off duty.

Courier Skins999 limited outfits and rides to wear in the game.

Skins change how you look, to you and to every player around you. They never change what you earn: $STAMP only comes from couriers on duty at post offices. Mint them in the Post office panel, then press Wear on one you own.

• Blind mint. Every skin is sealed until the mint ends, then revealed by a secret committed before the mint, mixed with a block hash at the reveal, so nobody (the team included) can pick the rare ones.
• Rides are faster to get around on: the Neon Scooter, Hoverboard, Neon Bike and Moonwedge each have their own speed.
• The 5% royalty is enforced. The contract checks every transfer: marketplaces can only sell skins in trades that pay it, so the royalty can't be skipped. You can always move your own skins between your wallets.
• Other players see your skin only if your wallet really owns it: the game's server checks it on-chain.

Post officesPut couriers to work and collect $STAMP.

Open a post office for 0.005 ETH. It comes with a trainee courier (60 power) who starts work straight away, so you can earn before you own an NFT. Put your own couriers on duty to add their power. Each office has a number of desks (couriers on duty at once) and routes; faster rides use more routes.

Upgrades go one tier at a time, with a 24-hour wait between them. Collect your $STAMP whenever you like from the post office panel.

Invite friends: when someone opens an office with your invite, you get 2.5% of what their office collects (taken from their share).

LevelsTrain a courier for more power.

Couriers go from level 1 to 10. Each level adds +12% to its base power, so a level 10 courier has 2.08× the power it started with. Training costs 25 × level² $STAMP, and levels stay with the NFT if it changes hands.

From level 1 to 10 costs 7,125 $STAMP in all.

$STAMPThe town's token: 21 million, ever.

Your share of each block's reward is your offices' delivery power over everyone's.

TradingBuy and sell $STAMP right in the game.

• $STAMP trades against IMD in one Uniswap v4 pool. Trade with IMD, or with ETH (routed through the IMD/ETH pool), from the post office panel.
• Every swap pays a 4% fee on its IMD side. Plain transfers, and everything the game does, are never taxed.
• The launch liquidity is $STAMP only and locked forever, so sells fill once buys have brought IMD into the pool.
• Each trade shows a quote with fees and price impact included, and is protected by a slippage limit.

Nothing here is financial advice. Tokens can lose value; only trade what you're happy to lose.

SafetyNobody holds the keys.

• Ownership of the NFT, its renderer, $STAMP and the pool's hook was renounced at launch. The post office never had an owner. Nobody can change the rules, mint extra tokens or move anyone's couriers.
• The courier art is frozen for good.
• Every contract's source code is verified on the explorer and published on GitHub.
• The contracts were reviewed by IMD Swarm: read the audit report.
