PancakeSwap: The BNB Chain DEX That Turned to Burns and a Supply Cap
BNB Chain’s well-known DEX and its token CAKE
PancakeSwap, launched in 2020 on BNB Chain, is a decentralized exchange (DEX), and CAKE is its token. It once leaned on paying out new CAKE as rewards, but it has since moved toward burning tokens and capping supply.
1. An anonymous team’s exchange on BNB Chain
PancakeSwap opened in September 2020 on what was then called Binance Smart Chain, now BNB Chain. Instead of a company matching orders, coins are swapped against pools of funds that users deposit (an automated market maker, or AMM), a design it initially borrowed from Ethereum’s Uniswap and SushiSwap. Its developers work under pseudonyms.
CAKE began as a reward handed to users who put funds into those pools. On the Crypto Nation map, CAKE stands in BNB Chain City, because it was first issued on BNB Chain.
2. Pools, rewards and burns
Users who deposit two coins into a pool provide ‘liquidity’ and earn a share of trading fees, and PancakeSwap has also paid CAKE as an extra reward. Pools carry ‘impermanent loss’, where a deposit ends up worth less than simply holding the coins if prices move a lot. Trading happens from the user’s own wallet, so the exchange does not hold customers’ assets.
CAKE’s issuance has changed a lot. ‘Tokenomics 3.0’, rolled out in April 2025, retired the veCAKE model (locking CAKE for a fixed period) and cut new issuance, while part of the exchange’s revenue is used to buy and burn CAKE. In January 2026 a token-holder vote lowered the maximum supply cap to 400 million.
3. Many chains, and ‘Infinity’
PancakeSwap runs on BNB Chain and several other blockchains, including Ethereum, Arbitrum and Base. Besides swaps it has added a lottery, price-prediction games, token-sale events and NFTs, and CAKE is used to take part in these and to vote on proposals.
In 2025 it released its v4 design under the name ‘Infinity’, which lets developers attach hooks (small programs that customize a pool) and aims to cut gas costs (network fees). Earlier versions were v2 and v3, the latter using concentrated liquidity.
4. Things to know
Because the team is anonymous, it is hard to hold anyone accountable when something goes wrong, and a bug in a smart contract (a program that runs automatically on a blockchain) could put user funds at risk. Security firms note that open-ended features such as hooks make careful audits even more important. Governance runs through off-chain Snapshot votes whose results the team carries out.
PancakeSwap depends heavily on BNB Chain, and because anyone can create a pool for a new token, scam tokens do get traded, so checking before trading matters. Competition from Uniswap and other exchanges is intense, and rules for decentralized exchanges are still taking shape in many countries.
