Courier

Welcome to the planetA tiny town, a bag of letters, and a game that lives on BNB Smart 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 BNB Smart 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

Chat

Talk to everyone on the planet in any language: press Enter (or tap 💬 Tap to chat on a phone), type, and send. Your message shows in the chat box and as a speech bubble over your courier. Text only: links and wallet addresses aren't allowed, so nobody can post scams, and messages are up to 140 characters, one every two seconds. Tap someone's name in the chat box to mute them; the settings (⚙︎) can hide chat or unmute everyone.

Photos

Tap 📷 (or press C) for photo mode. The buttons step aside and the camera is yours: drag to look all the way round, from overhead down to the ground looking up at the sky; scroll or pinch to zoom from the whole planet's curve right in to your courier's eyes. Set the clock to any hour (sunsets are lovely), hide your courier if you like, then press the shutter (or Space) to save the picture, or share it straight from your phone. Press C, Esc or Done to go back to playing.

Your name

Players show as their wallet address (or "Guest"). To pick a name instead, open the Post Office panel, tap ✏️ Pick a name, type 3 to 15 letters, numbers or _, and save: your wallet signs to confirm (free, no transaction). Your name then shows on your name tag, in chat, on your post office and on the leaderboard. Names are first come, first served, and you can change yours once a day (or go back to your wallet address).

Ads on the Orb

The Orb shows paid ads from other projects, each for a set time (several take turns every 20 seconds), and the ad on it also plays on Times Square's big screens. Tapping either opens the ad's card with its website and chart. Every ad is checked by the team before it goes up, but an ad is not an endorsement: always do your own research before you buy anything or connect your wallet. Want your project on the Orb? DM @PlayCourierWld on X.

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. When the treasury runs a $STAMP drop they pay $STAMP: see Treasure hunt.

The moon and Mars

The rocket in the neon district is the Space Express. Stand by it and press E (or tap Hi), then pick where to fly:

• The moon (100 $STAMP): a small grey world of craters and rocks, with Courier World hanging in a black, starry sky. Gravity is low, so jumps go about three times as high. The moon frogs live up there: Officer Zorp greets new arrivals at the pad, Captain Gloop, Blib and Kiki hang out at Moon Base, Professor Tadwick maps the stars at his telescope, and Old Croak keeps to his hut on the far side. Look up, too: their flying saucer circles the moon.
• Mars (200 $STAMP): a red world as big as Courier World, with two little moons in a butterscotch sky. You land at the spaceport, by two tall rockets and a launch tower. Mars City is next door: a big glass plaza dome you can walk into, with a garden and a fountain, ringed by greenhouses, homes, pools, farms and a ring road. Red mountains rise beyond it, and further round there's a long winding canyon, a big sleeping volcano and an ice cap at the bottom. Twenty locals live there: seven Martians (Mayor Zibble, Dr. Rusta, Pip, Geo, Old Ozzy, Tula and Nix) and thirteen astronaut colonists, from Commander Ada in the plaza to Climber Juno up in the mountains. Pip's rover is parked in the garage by the spaceport: press E by it to hop in and drive, and E again to hop out. Every seven minutes or so a dust storm blows through for a minute and a half.

Both have letters: the post box by the landing pad (the Moon Post, the Mars Post) hands you three letters for the locals, and the arrow at the top shows the way to each. They count toward your deliveries. Both also have twelve golden stamps out every day, some only a big jump reaches, that count with your golden stamps (paid by the same $STAMP drop, when the treasury runs one). Couriers on the same world see and chat with each other. Walk up to anyone and press E to chat.

A ticket is sent from your wallet to the Courier World treasury and lasts an hour: fly home any time from the rocket by the landing pad, and the rocket brings you home when it runs out. You need to be logged in and signed in to the hunt (a free signature) so the game's server can check your ticket. Your ticket survives a reload: fly back from the neon district.

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.
• Pay in BNB or $STAMP. Each skin costs 0.004 BNB, or 150 $STAMP (one signature, no separate approval). The same 999 skins either way.

Post officesPut couriers to work and collect $STAMP.

Open a post office for 0.005 BNB. 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 BNB (routed through the IMD/BNB 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.

LaunchpadLaunch your own token, right in Times Square.

• The Launchpad is the ground floor of Times Square's corner tower: walk up and press E (or Hi), tap its sign, press L, or use the button in the post office panel.
• Anyone with a post office can launch a token. Give it a name, a symbol, a picture, a description and links. Launching burns 100 $STAMP.
• Every token has 1,000,000,000 supply and no owner, no minting and no tax. 95% goes into its own pool against IMD, locked for good, so it can always be traded. 5% goes to the Courier World treasury for drops to post offices.
• Every launch starts at the same market cap (about $5,000). Buy and sell any token with BNB or IMD from its page; every trade pays a 4% fee on its IMD side to Courier World.
• The three biggest tokens (by market cap) show on a Top 3 coins screen in Times Square, and the five biggest on the ticker.

Tokens are made by players, not by Courier World. Most go to zero: do your own research. Tokens that copy the game's own names or break the rules aren't shown in the game, but still trade on-chain.

Treasure huntReal tokens scattered round the planet as coins.

• The treasury drops real tokens, from the Launchpad, round the planet as coins with the token's picture on them. They're out at new spots every day (00:00 UTC), in the open, up high, or where only a jump reaches. A $STAMP drop pays for the golden stamps too.
• Walk into a coin to collect it. Every player can collect every coin, and your finds show in the post office panel's Treasure hunt section.
• Only players with a post office open can redeem. Sign in to the hunt once (a free signature, no transaction), then claim everything you've found, every drop at once, with one transaction. Claim by the end of the next day (UTC).
• Each drop pays a few coins per wallet a day, and a set number a day across everyone, while its tokens last. The game's server checks every find against where you've actually been.
• While a drop is on, a running line across the top of the screen says how many coins are out today (and how many you've found), how many are left to claim today, what each pays and when the next ones come out. The Post Office panel's Treasure hunt section shows the same, with a bar of today's coins left to claim.
• Times Square's screens and ticker say which coins are out.
• On the moon and Mars, twelve more golden stamps are out on each every day. They're paid by the same $STAMP drop as the golden stamps, within the same daily limits.

The tokens come from the Courier World treasury (5% of every Launchpad launch). Drops are funded only by the treasury, which can pause claims if anything looks wrong. Reviewed by IMD Swarm: read the audit.

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.
• The Launchpad keeps an owner, who can change the launch fee (at most 100,000 $STAMP) and the starting price of new launches; a launch on its way never pays more or starts elsewhere than it showed. The owner can't touch launched tokens, their pools or anyone's balances, and their liquidity can never be removed. Reviewed by IMD Swarm: read the Launchpad audit.
