PancakeSwap (CAKE)

PancakeSwap (CAKE) is the native token of PancakeSwap, a decentralized exchange launched in September 2020 that is the largest trading venue on BNB Chain. CAKE is paid out as a reward to people who supply trading liquidity, is used in the exchange's products and governance votes, and is regularly bought back and burned with part of the exchange's fees.

PancakeSwap is a decentralized finance application, not a blockchain. It runs mainly on BNB Smart Chain, whose native coin is BNB (BNB), and has also been deployed on Ethereum, Arbitrum, Base and several other networks. Its design closely follows Uniswap (UNI), and its token standard on BNB Chain is BEP20. The team behind it is pseudonymous and is not part of Binance.

Picture a currency exchange booth with no staff. Instead of a cashier setting prices, the booth holds two jars of coins, say BNB and a stablecoin. Anyone can swap one for the other, and the booth adjusts the price automatically according to how full each jar is. The jars are filled by ordinary users, who lend their coins to the booth and earn a cut of every swap fee.

CAKE is the booth's loyalty token. The exchange hands it out to attract people who fill the jars, and it takes part of the fees it collects to buy CAKE back and destroy it. Whether the total amount of CAKE grows or shrinks depends on which of those two forces is stronger in a given period.

PancakeSwap launched in September 2020 on what was then called Binance Smart Chain, attracting users with lower fees than Ethereum at the height of "DeFi summer". Version 2 followed in April 2021 and version 3, with concentrated liquidity, in April 2023, when the exchange also began expanding to other chains. In December 2023 holders voted to cut CAKE's maximum supply from 750 million to 450 million. PancakeSwap Infinity, the rebranded fourth version, went live on 28 April 2025 with "hooks" that let developers add custom logic such as dynamic fees to pools. In January 2026 holders approved a further cut in the maximum supply to 400 million CAKE.

PancakeSwap's classic pools are automated market makers that follow the constant-product rule:

• $x$ is the amount of the first token in the liquidity pool.
• $y$ is the amount of the second token in the pool.
• $k$ is a constant that a trade must preserve, before fees.

Version 3 and Infinity pools also let providers concentrate their funds within a chosen price range, which uses capital more efficiently but needs more active management. Each swap pays a small fee that is shared between liquidity providers, the treasury and CAKE burns, with the split depending on the pool version and fee tier.

Take a pool holding 1,000 BNB and 600,000 USDT, so $k = 600{,}000{,}000$. A trader who adds 10 BNB leaves 1,010 BNB in the pool, which must now hold $600{,}000{,}000 \div 1{,}010 \approx 594{,}059$ USDT. The trader receives about 5,941 USDT before fees, an average price of about 594 USDT per BNB rather than the starting 600. The gap is slippage, and it grows with the size of the trade relative to the pool. Liquidity providers receive LP tokens for their share and are exposed to impermanent loss when prices move. Variants for other pool types are covered in formulas for automated market makers.

From 2023 to 2025 PancakeSwap used a vote-escrow model, veCAKE, in which holders locked CAKE for up to four years to vote on how emissions were spread across pools. Tokenomics 3.0, approved in April 2025 and implemented from 23 April 2025, retired veCAKE and its voting gauges, unlocked staked CAKE (holders had until October 2025 to redeem), cut daily emissions and moved emission decisions to the core team. Its stated aim is a net fall in supply of about 4 percent a year through burning, funded by trading fees and other products, with a target of roughly 20 percent less supply by 2030. The result is a form of deflationary tokenomics, though burns depend on trading activity.

Critics note that early PancakeSwap paid very high CAKE rewards that diluted holders, and that Tokenomics 3.0 concentrated control over emissions in the hands of the pseudonymous team, weakening governance. Like other DEXs, it lists tokens without permission, so many pools contain meme coins and outright scams. In March 2021 attackers hijacked the site's domain name records in an attempt to trick users into giving up wallet keys. Smart-contract bugs, the dominance of a single chain and competition from rival exchanges are further risks. The exchange also depends on the health of BNB Chain itself: an outage, a security incident or a loss of users on that network would hit PancakeSwap's volumes, and therefore its fee income and burns, directly. Finally, CAKE is not a claim on the exchange's profits, so holders rely on the team continuing to direct fees to buybacks.
