Blip Market

Blip Markets is a micro-prediction trading platform where users forecast whether an asset’s price will touch specific predefined ranges within a fixed time window. Instead of predicting direction, participants select price bands and time durations, and win if the live chart reaches that range before expiry. This transforms short-term volatility into precise, binary market outcomes that are simple to understand and fast to act on.

The platform is designed for rapid, tap-based interaction, allowing users to enter markets in seconds and express highly granular views on price movement. By focusing on time-bound range predictions rather than traditional buy/sell trading, Blip Markets creates a new trading experience built around precision, speed, and real-time market behavior.

Blit Market is a grid-based micro prediction engine where users stake USDC on discrete price-time cells overlaid on live crypto charts. Built for Base, it delivers deterministic, zero-sum outcomes resolved entirely on-chain.

Coinbase Integration: We tap directly into Coinbase's WebSocket feed (wss://ws-feed.exchange.coinbase.com) for real-time ETH-USD price data. This powers both our live charting and settlement—when a prediction window closes, we fetch the actual price history from Coinbase to determine winners with zero oracle dependency.

Base Blockchain: All stakes and payouts flow through USDC on Base. We chose Base for its low gas costs and Coinbase ecosystem alignment. Our treasury contract handles deposits and the relayer executes settlements on-chain. Privy: Authentication is fully powered by Privy - users can onboard with just an email and get an embedded wallet instantly. No seed phrases, no friction. We exchange Privy's access token for a platform JWT, keeping sessions secure with httpOnly cookies.

Gasless UX: Users never pay gas. We implemented EIP-2612 permit signatures so users sign once, then our relayer hot wallet handles all transactions. To maximize reliability, we broadcast every tx to 5+ Base RPC endpoints simultaneously (1rpc, publicnode, llamarpc, blastapi) and treat "already known" as success.

The Math: Our share-based pricing uses a Black-Scholes-inspired probability model with custom Abramowitz & Stegun CDF approximation - no external math libraries, fully deterministic. Users buy "shares" at calculated probabilities, and winners split the pool proportionally.

Stack: Go backend + React/TypeScript/Vite frontend + TimescaleDB for price snapshots + Redis for real-time caching + WebSockets for live updates.
