BettiFy

Bettify is a gasless prediction market infrastructure built using Yellow Network and the Nitrolite protocol. Instead of executing every bet and settlement on-chain, VaultOS uses Yellow’s off-chain ledger and state-channel-based transfers to enable instant betting, refunds, and market settlement with zero gas fees and sub-second finality.

Users authenticate using EIP-712 signatures, deposit funds into a session-based off-chain ledger, and place bets that are instantly recorded without waiting for blockchain confirmation. Market resolution and refunds are handled off-chain and finalized only when needed, significantly improving UX, speed, and capital efficiency compared to traditional prediction markets like Polymarket

Bettify is built using the Yellow Network SDK and the Nitrolite protocol for off-chain transaction handling. The backend connects to Yellow’s sandbox WebSocket endpoint to authenticate users via EIP-712, query ledger balances, and execute real ytest.usd transfers on Yellow’s off-chain ledger.

Market logic is handled by a Node.js TypeScript service that simulates prediction market behavior while relying on Yellow for real value movement. Bets, refunds, and settlements are processed as off-chain transfers, demonstrating session-based spending and instant settlement. Faucet APIs are used for sandbox testing, and raw ledger balances are tracked to prove accurate accounting and zero-gas execution.
