What is Provably Fair Trading? Catapult's GBM Algorithm Explained

Every traditional crypto trading platform has the same vulnerability: the platform operator controls the price feed. They can rug, they can manipulate, they can front-run. Catapult Turbo was built to make that impossible — not through trust, but through mathematics and on-chain verification.

What is Geometric Brownian Motion?

Geometric Brownian Motion (GBM) is the mathematical model used by quantitative finance to simulate asset price movement. It's the same model that underlies Black-Scholes options pricing and is used by major financial institutions worldwide. GBM produces realistic-looking price charts with natural volatility, trends, and reversals — all derived from a mathematical formula with a seed value.

The key property: given the seed, the entire price chart is deterministic and reproducible. Anyone can verify it.

The on-chain commitment

Before a Turbo session opens for trading, Catapult commits the chart seed to the blockchain using a Keccak-256 hash. This hash is publicly visible on-chain before a single trade is placed. After the session closes, the original seed is revealed — and any trader can independently verify that the chart matches the committed hash.

This makes price manipulation mechanically impossible. The chart is fixed before trading begins. The platform can't change it after the fact without invalidating the on-chain commitment.

Zero slippage, no order books

Catapult Turbo doesn't use an order book. Trades are executed against the deterministic price curve directly. This means zero slippage — every trade executes at exactly the displayed price, no matter the size. Large positions don't move the market.

LP is burned at graduation

When a token session ends and the token graduates, the liquidity is burned. This means the platform operator cannot drain the pool — it's mechanically impossible for a rug pull to occur at graduation. Combined with the on-chain hash commitment, this closes every traditional attack vector.

Verified by Hashlock

Catapult's smart contracts and the GBM pricing algorithm have been audited by Hashlock, the firm that also audited Gala Games and PancakeSwap. The audit confirmed that the on-chain commitment mechanism works as described and that the contracts are free from known vulnerabilities. The full audit report is publicly available.
