What is ARCIRCUIT?
ARCIRCUIT is a one-tap daily skill arena built on Arc Mainnet. Players fire pins into a rotating core, advance through increasingly dense levels and compete for the best replay-verified score in each published 24-hour round.
Practice works without a wallet. Ranked transactions remain unavailable whenever no verified V4 vault and active on-chain round are configured.
One payment unlocks one continuous run.
A run begins at Level 1 and continues until a fired pin collides with an existing pin. Clearing a level preserves the run and moves the player to a harder pattern. Practice never reaches the ranked board.
| Level | Pins to clear | Change |
|---|---|---|
| 01 | 5 | Learn the orbit |
| 02 | 10 | Read the rhythm |
| 03 | 15 | Speed rises |
| 04+ | 20–30 | Direction and spacing tighten |
Timing creates the score.
Every safe pin earns a base score plus a speed bonus, multiplied by the live combo. A level clear adds the published level bonus. The verifier replays the exact input ticks using the same deterministic rules before accepting the score.
A clean board every 24 hours.
Every round has exact on-chain UTC opening and closing timestamps. No ranked attempt can start outside that window. Ties favor the result that completed verification first. Completed rounds keep their results commitment and settlement transaction.
80% players. 10% next round. 10% treasury.
The complete round value includes player entries, sponsor funds committed before the first entry and inherited rollover. Player allocation adapts safely to the number of distinct verified winners.
| Verified winners | Player allocation | Total round shares |
|---|---|---|
| 3 | 50% / 30% / 20% | 40% / 24% / 16% |
| 2 | 62.5% / 37.5% | 50% / 30% |
| 1 | 100% | 80% |
The remaining 10% is reserved inside the vault for the next created round and 10% becomes claimable by the configured treasury.
A browser score is not enough.
- Each entry emits a unique attempt identifier on Arc Mainnet.
- The server binds the confirmed entry to a random seed and expiring challenge.
- The wallet signs the completed result and input-trace commitment.
- The server replays the trace under fixed-step deterministic rules and accepts only an exact score match.
- Duplicate attempts, impossible timing and traces that do not end in a collision are rejected.
- The settlement hash is domain-separated by Arc chain ID and the deployed vault address.
Canonical addresses, explicit decimal rules.
ARCIRCUIT targets chain ID 5042 and the official RPC at rpc.mainnet.arc.io. The application reads and transfers USDC through the canonical six-decimal ERC-20 interface. Arc's native USDC gas balance uses 18-decimal accounting; the game never uses msg.value for entry payments.
Direct answers.
What is live now?
ARCIRCUIT targets Arc Mainnet. Practice is free; ranked entry remains locked whenever no verified V4 vault and active round are configured.
What asset does ranked play use?
Arc Mainnet USDC through the canonical ERC-20 interface at 0x3600000000000000000000000000000000000000. Each ranked entry costs 1 USDC.
Can a round settle with fewer than three players?
Yes. V4 supports one, two or three distinct verified winners, so a low-participation round does not become stuck.
Is there an ARCIRCUIT token?
No token is configured, advertised or required by this build.
Is ARCIRCUIT affiliated with Arc or Circle?
No. ARCIRCUIT is an independent application built on Arc and is not affiliated with or endorsed by Circle or Arc.
