KLONK

How It Works

Every round waits for Bitcoin, then settles on Robinhood Chain.

Klonk is an ETH prediction arcade. Bitcoin mainnet block data decides the result, and the Klonk contract on Robinhood Chain handles stake accounting, settlement, winner claims, no-winner refunds, and NAT holder revenue.

01

Choose a side

Connect MetaMask (or WalletConnect) on Robinhood Chain, choose Even or Odd, and enter any positive ETH stake. While the round is open, you can add more ETH or switch sides.

02

Bitcoin decides

Each round targets a future Bitcoin mainnet block. For the live game, Klonk reads that block nonce and resolves the parity result from the Bitcoin data.

03

Round locks

The round locks as soon as the target Bitcoin block is mined. After that, no new entries, added stake, or side changes are accepted.

04

Finality check

If the winning side has stake, Klonk waits for 2 successor Bitcoin blocks before declaring winners. This delay reduces orphan/reorg risk.

05

Immediate refund

If the target block picks a side with no stake, there are no winners. The round becomes refundable immediately and does not wait for the 2-block delay.

06

Claim on-chain

Winners and refunded players claim from the Klonk smart contract on Robinhood Chain with their wallet. Payouts are not pushed automatically.

Settlement Rule

Winners wait. Refunds do not.

Prize pool

Platform and NAT revenue are reserved from the total ETH pool. Winners split the remaining winner pool by their share of winning-side stake.

Winner visibility

Winner addresses and payouts are shown only after the round is finalized. Refunded rounds show no winners and unlock refund claims immediately.

NAT revenue

The NAT collection is separate from games. Revenue is batched into epochs and distributed pro-rata by NAT token balances at epoch close.

Bitcoin role

Bitcoin is only the result data source. Klonk does not inscribe a game engine on Bitcoin for gameplay.

Trust boundary

The backend oracle submits the Bitcoin-derived result to the Klonk contract on Robinhood Chain. Mainnet launch requires stronger oracle monitoring, audits, and legal review.
