Twelve possible endings. About 93% of universes never grow anything. The rest get stars, some get planets, a few could grow observers.
You detonate blocks for free, no wallet needed. If you like the universe you got, you mint it. One block hash makes exactly one universe, and once it is minted nobody can ever mint that block again.
The 3D view runs a real N-body simulation (up to two million particles in WebGPU). Universes with more than three dimensions are integrated in D dimensions and projected onto the three axes you choose.
Why ArcArc is Circle's Layer-1 where gas is paid in USDC. That is what makes the economics readable: dollar-priced mints with no oracle, free mints that cost only about 0.003 USDC of gas, royalties and secondary sales settled in dollars. No token. No presale. No airdrop.
Arc's block history also stamps provenance on-chain: a universe minted within about an hour of its block is marked verified by the chain itself, not by our server.
Supply and phases- Supply: 1,387 universes. No further issuance, ever. (The universe is 13.787 billion years old; one NFT stands for ten million years.)

How to get whitelistedSign in with X on the quest page, connect a wallet and sign once (no gas). Points: register 10, follow 20, engage with the pinned post 50, other official posts 20 each, detonate universes 1 each (up to 50), detonate and broadcast 3 each (up to 15 times), original posts 20 each, invites 10 each. Engagement is verified automatically through the X API. The public leaderboard shows the top 100; the top 387 by points are guaranteed a free mint.

arcbang.xyz/check.htmlContracts (Arc mainnet, chainId 5042)Two single-file contracts, no external dependencies. Total supply is a compile-time constant; the free cap and per-address limits can only be tightened, never loosened. 157 contract tests run against the real bytecode, 465 tests on the physics engine. If our metadata server ever disappears, tokenURI falls back to an SVG rendered entirely on-chain. Anyone can recompute a universe from its block hash:
arcbang.xyz/verify.htmlFAQIs there a token? No. Never.
Do I need USDC to play? No. Detonating is free and needs no wallet. Minting needs a few cents of USDC for gas on Arc.
Can I trade on OpenSea? Yes. OpenSea indexes Arc; the built-in market also works and charges no fee beyond the 5% royalty.
Which wallet? Any EVM wallet (MetaMask etc.). The site adds and switches to Arc automatically.
