WarmUp Chain is an EVM chain built for on-chain games and apps. Zero gas, 1-second blocks while there are transactions, and wUSD backed 1:1 by USDT on BSC. Your own browser takes part in every random result, and anyone can run an observer node to check the whole chain.
Why WarmUp
The platform runs the chain and is also the house in its games. So instead of asking you to trust it, the system is built so that the platform can't cheat, and if it tries, it leaves public evidence.
Each result is decided jointly by your browser and the platform; drand, a public randomness network, steps in only when something goes wrong. Results land 1–2 s after you click. If the platform holds back your reveal, your browser notices on the spot, and a signed receipt lets you claim on chain.
How the randomness stays fair →Every block and transaction is public. Independent observer nodes check every block hash; if history is ever rewritten, they raise an alarm and keep both versions as evidence. Observers don't produce blocks or affect the chain, and run on a 2-core, 4 GB machine.
Run an observer →Players need no wallet and no gas. wUSD is backed 1:1 by USDT in a BSC vault: deposits arrive in about 20 s, withdrawals in about 15 s. On testnet it uses BSC testnet USDT, and developers also get sbUSD, a free test coin.

Kit + watch dashboardAccounts and safety
Players use custodial accounts: no seed phrase, no gas. Every on-chain action still comes from the player's own address, so anyone can check it in the explorer.
The platform signs only what each app has registered: registered contract methods only, token approvals only to that app's own contracts, with per-transaction and daily caps, and every signature goes into an append-only audit log. If one app goes wrong, losses are capped at what players approved for it.
Sign in with Face ID, a fingerprint or your device passcode, with no wallet app to install; MetaMask and other browser wallets work too. Both can be linked to one account so losing one doesn't lock you out.
Any game or dapp can be paused at once, or all of them together, within a second. While paused, nothing can be bet or traded, but players can still see their history and withdraw their balance.
New app code is security-reviewed; then one person marks the review approved and a second person switches it live before the platform signs for it. The four live games went through 4 rounds of internal audit.
Ecosystem
Games and dapps share one custodial account and wUSD. The dapps live inside the game platform for now and will move to their own warmup.land subdomains.
Coin flip, dice, Crash, rock-paper-scissors, Fomo3D and more. Sign in with a browser wallet or a passkey; every round can be recomputed in your browser.
game.warmup.landEach name is an NFT rented yearly in wUSD, and can point to a payment address and a profile. Its DID, did:up:name, resolves to a standard DID document for anyone.
A constant-product swap between wUSD and the AI token; the 0.3% fee goes to liquidity providers. Every trade has slippage protection and a deadline, and shows the quote next to the price you got.
1 billion supply, no minting, no admin. Launched fairly: all of it went into the AI/wUSD pool, the liquidity shares were burned, and the team kept none.
