What is a bonding curve in simple terms?

A bonding curve is a pricing formula where the next token costs slightly more than the last one bought, and slightly more than the last one sold is worth. It creates an automatic market without needing a broker or market-maker.

What formula does THRYX's bonding curve use?

THRYX uses a constant-product formula: virtualThryx × virtualTokens = k. Each token is seeded with 1,000,000,000 virtual THRYX and 1,072,000,000 virtual tokens. Prices are derived from the ratio, identical to how Uniswap V2 prices AMM swaps.

Why virtual reserves instead of real ones?

Virtual reserves set a predictable starting price and smooth curve shape without requiring the creator to seed real liquidity. No real THRYX is locked at launch; the virtuals exist only in curve math.

When does the bonding curve end?

At 250,000,000 THRYX raised, the token graduates. The bonding curve is disabled, unsold supply is burned, and 15% of the raise seeds a permanent Uniswap V4 Token/THRYX pool.

What Is a Bonding Curve? Token Pricing on Base Explained

4 min read

When a THRYX token launches, its price is not fixed. The price moves up and down based on how many people are buying and selling. The pricing system is called a bonding curve.

The Vending Machine Analogy

Imagine a vending machine with 1,000 candy bars inside. The first candy bar costs $0.01. The second costs a tiny bit more. By the time someone buys the 500th, it might cost $1.00. Now imagine the vending machine also buys candy bars back at the current price minus a small fee.

That's a bonding curve. The more people buy, the higher the price goes. The more people sell, the lower it drops.

Why This Matters for Token Creators

Traditional stock markets need a company to set a price, find buyers, and list on an exchange. That takes months and costs thousands. With a bonding curve, pricing happens automatically from the very first trade.

How the Price Actually Moves

Token launches. Price starts near zero.
First buyer purchases some tokens. Price ticks up slightly.
More buyers come in. Each purchase pushes the price a little higher.
Someone sells. The price drops back a bit.
The cycle continues. Price reflects real demand at all times.

The Trading Fee

Every trade has a 1% fee — one of the lowest on Base. 70% goes to the token creator. 30% goes to the protocol. As the creator, you earn from every trade, whether the price goes up or down.

What happens when a token graduates on THRYX?

A THRYX token graduates when its bonding curve raises 250,000,000 THRYX. At graduation, unsold supply is burned, 15% of the raise seeds a Uniswap V4 Token/THRYX pool, and the token trades as a standard ERC-20 on every Base DEX aggregator (DexScreener, GeckoTerminal, DeFiLlama, 1inch, Matcha). Graduation converts bonding-curve liquidity into permanent AMM liquidity. Source: thryx.fun/glossary#graduation.

Why are bonding curves fairer than book-building?

Everyone sees the same on-chain price. No insider deals, no pre-allocations.
First buyers always get the lowest price. Early supporters are structurally rewarded.
The price cannot be manipulated by one person — every trade moves the same shared curve.
Liquidity is always available. A trader can always buy or sell at the posted price (subject to slippage).
