D20DAO EXAMPLES · DEMO NOTICE

A playground, with clear limits.

This is an experimental demonstration for learning and testing. There are no wagers or prizes. Mainnet mode spends real USDC on service fees and gas.

Choose your network or preview

Testnet wallet mode sends real transactions on Arc Testnet through your browser wallet. It uses the existing D20Playground contract and displays the coordinator’s accepted result. Each transaction requires your approval and spends test USDC on the request fee and network gas. Read the current fee and maximum payment before signing.

Mainnet wallet mode uses Arc Mainnet and the deployed D20Playground consumer. Requests spend real USDC and network gas. Review the displayed network, fee and maximum payment before approving in your wallet.

Local preview mode generates browser randomness and maps it with the D20DAO SDK. Its illustrated API, epoch, proof and callback steps are a simulation, with no wallet transaction or VRF proof.

The 3D motion displays an already selected result. It is not the source of randomness. A displayed value is not a token, reward, redeemable asset or claim to future benefits.

No wagers or prizes

This demo does not place bets or pay winnings. Do not use its results to settle wagers, distribute real assets or make financial decisions. Never enter a private key or recovery phrase.

A request may expire without a result. Its refundable share is set by the protocol; gas is separate. An accepted result cannot be refunded or rerolled by retrying its callback. The page reads RPC data and checks the SDK mapping, but does not independently replay the cryptographic proof.

Arc testnet tokens have no monetary value under the Arc Testnet terms. Mainnet USDC has real value. Testnet and local preview modes are available for trying the interface without mainnet fees.
