TAPL

TAPL is a real-time tap trading platform where users can predict the price movements of crypto assets (like BTC, ETH, and LINK) with a single tap. It also allows users to "Be the House" by depositing tokens into a liquidity pool to mint LP shares and earn yields based on the platform's mathematical edge.

The app displays a live price chart overlaid with a grid powered by real-time Chainlink data. Each cell in the grid represents a specific price range paired with a time window. The closer a cell is to the current price, the lower the payout, while cells further away offer a higher reward. Users simply tap a cell, and their bet is instantly locked at the exact oracle timestamp with a frozen multiplier. Behind the scenes, the pricing engine runs thousands of simulations every 100 milliseconds to calculate fair odds. Once a betting round closes, Chainlink CRE workflows batch the outcomes and commits them on-chain, immediately updating the user's withdrawable balance.

Most traditional prediction platforms suffer from a major trust problem: opaque pricing, fake balances that block withdrawals, and the risk of platform insolvency. TAPL solves this by operating on a completely transparent, verifiable model where users do not have to blindly trust the platform. Thanks to CRE, every bet, outcome, reward rate, and token movement is permanently recorded on-chain, guaranteeing that prices are real, odds are fair, and the platform always has the funds to pay winners

TAPL's architecture relies heavily on mathematical modeling and a deep integration with Chainlink Data Streams and Chainlink CRE.

• The Fortress Model: To ensure the odds are always fair, the core pricing engine is built on four pillars: volatility tracking, touch probability, path simulation, and risk management.
• Chainlink CRE Workflows: The system operates via four automated workflows that process inputs and push verifiable outputs on-chain:

1. Price Integrity CRE Workflow: Streams live prices from Chainlink's WebSocket and compares them against Chainlink's reference feed every 15 minutes to prove that the platform never manipulates the price.
2. Settlement CRE Workflow: When a betting window closes, it reads the Open-High-Low-Close candles and active bets, runs the logic to determine a win or loss, batches the results, and commits them on-chain so users can withdraw their funds automatically.
3. Pool Solvency CRE Workflow: Every 60 seconds, it evaluates the pool balance, total liabilities, and active bets to compute and publish a solvency ratio on-chain. This proves the treasury always has enough funds to cover payouts.
4. Strategy Rebalance CRE Workflow: When the system detects a shift in market volatility, it automatically computes new risk parameters (like max bet multipliers and risk budgets) and permanently publishes the updates on-chain.
