BETOKEN

BETOKEN is a community-focused prediction market on Telegram for trading and creating event tokens. Anyone can participate by creating markets and buying predictions via a Telegram mini app.

Core Features:

• Token creation, each option in the prediction market is an ERC20 token
• Two types of markets supported: general and price markets:
  • General: Any topic, market creators act as the oracle. Open market creation, increased topic range and creative opportunity.
  • Price markets: Price markets, for example to predict the price of ETH/USDC in the future. Uses Chronicle as the oracle.
• Quick & easy funding: Supports on-ramp via external wallet, Moonpay, Coinbase, or in-app swaps
• Better wallet UX: Leverages Privy embedded wallets to be able to sign and send transactions from within the Telegram mini app.
• Reputation scoring: Uses various factors to determine a score for each user. This is especially useful for trust in open market creation and resolution. These are the factors supported and their purpose:
  • Wallet activity & balances: Onchain activity and prevents bots, external wallets can only be linked to one BETOKEN account.
  • EAS Attestations e.g. Coinbase trading account, country: Benefit from 3rd party platform verifications, e.g. Coinbase KYC
