Your bags
are your army
Mempire turns any meme coin into a battle-ready fighter. Mint a card from a token, stake into it for power, build a deck of eight, and drop them on a live battlefield against another player — with real SOL on the match.
Free to try on devnet. No real funds move until mainnet.
Sixty-four fighters. Every one a real ticker.
Twenty majors, twenty equities, twenty-four pump.fun memes — each drawn as itself, not reskinned from a shared rig.
Hold. Mint. Stake. Battle.
Four steps, and every one of them traces back to a token you genuinely hold. Break that chain anywhere and the game stops meaning anything.
- Hold
Your bags are the roster
Connect a wallet and Mempire reads what you actually hold. Coins under $25k liquidity or younger than 48 hours are refused — that gate is what stops anyone minting a god card out of a token they launched this morning.
- Mint
A coin becomes a fighter
The mint address is hashed into one of six archetypes — tank, swarm, ranged, splash, support, spell. It is global and permanent, so $BTC is the same class of fighter in your deck as in everyone else’s. Nobody rerolls.
- Stake
Conviction is power
Stake the token into its own card to raise its level. The curve is deliberately brutal at the top — ten levels on 1 + 0.6·√((lvl−1)/9) — so a whale buys an edge and never a win. Unstaking is a 72-hour two-step.
- Battle
Both players stake. One takes the pot.
Real-time lane battles: towers, bridges, elixir, cards dropped on a live field. Both sides put SOL in, the winner takes it out. Inputs land on a MagicBlock ephemeral rollup, so the match is onchain and still runs at 20 ticks a second.

It already runs
These are screenshots of the build, taken from the running app — not concepts, not renders. The full loop works on devnet today.
The arena
Two towers, one bridge, ten elixir. Every fighter on the field is a token somebody holds.
Your collection
Filter by memes, majors, or equities. Mint what you hold; stake what you believe in.
Pick your stake
Four tiers from 0.05 to 5 SOL. Ranked and Rush are humans only — the bot lives in Practice.
Eight slots
Three saved decks. One card per coin, so you cannot stack the same bag eight times.
Onchain, and still real-time
Card plays commit to a MagicBlock ephemeral rollup while both clients run the same deterministic lockstep simulation — fixed-point maths, twenty ticks a second, a state hash every forty ticks. If the two sides ever disagree, the match voids and both stakes come back. Escrow and payout stay on Solana itself, so a delegated match log can never strand a pot.
Both players stake.
One takes the pot.
Four power-bracketed tiers. Both sides put the same SOL in, the winner takes it out, and the 10% rake is printed on the screen where it applies. A draw splits at 5%.
Stakes and fees are the game's design, set in the program. They are not a promise about returns.
| TIER | STAKE | WINNER TAKES |
|---|---|---|
| Pauper | 0.05 SOL | 0.09 SOL |
| Knight | 0.25 SOL | 0.45 SOL |
| Duke | 1 SOL | 1.8 SOL |
| Emperor | 5 SOL | 9 SOL |
Questions
Everything below is checkable against the build.
What is Mempire?
Mempire is a real-time card battler on Solana where every fighter is a coin you actually hold. You mint a coin into a card, stake the token into that card to raise its level, build a deck of eight, and battle another player for a staked SOL pot.
Is Mempire free to play?
Yes. The build runs on Solana devnet, so no real funds move. You can play in any browser without installing anything — connect a wallet, or use guest mode to try the full loop without one.
Which wallet do I need?
Phantom, Solflare, Coinbase Wallet, Trust or Nightly all work. There is also a guest mode that simulates a wallet, so you can play the whole game before connecting anything.
How does a coin become a card?
The mint address is hashed into one of six archetypes — tank, swarm, ranged, splash, support or spell. It is global and permanent, so $BTC is the same class of fighter in everybody’s deck. Nobody rerolls, because there is nothing to reroll.
Can a whale just buy the best cards?
No. Level comes from staking a coin into its own card, on a curve of 1 + 0.6·√((level−1)/9). A level 10 card is 1.6× a level 1 card and that is the entire range, so spending ten times more buys nowhere near ten times the power.
Which coins can I mint?
Any coin you hold with at least $25,000 of liquidity that is more than 48 hours old. Both gates exist to stop anyone launching a token, buying it all, and minting a card nobody can contest.
Is the game actually onchain?
Cards, levels, staked balances, match escrow and payout are all Solana programs. Card plays during a match run on a MagicBlock ephemeral rollup so the game can tick twenty times a second, and both clients run the same deterministic simulation — if they ever disagree the match voids and both stakes return.
What is $MEMPIRE?
$MEMPIRE is the in-game token, tradable against USDC through a real constant-product pool. It skips chest timers, enters tournaments and buys cosmetics. It never buys stats — card power comes only from staking the card’s own coin.
Is there a mobile app?
Not yet. The game runs in any mobile browser today and can be added to a home screen. A React Native build is in development for Google Play, the App Store and the Solana dApp Store.
How much is the rake?
10%, printed on the screen where it applies. Both players stake the same amount, the winner takes 90% of the pot, and a draw splits at 5% instead.
