# BNB Chain Memecoins: four.meme Launches and Volume > BNB Chain memecoins launched per day on four.meme and other launchpads: tokens created, graduated to PancakeSwap, trading volume and launchpad fees in BNB. Markdown copy of https://voltfincrypto.com/apps/bnb-chain-memecoins **Question:** How many memecoins launch on BNB Chain each day, how many graduate to PancakeSwap and how much do they trade? - Kind: Dashboard in Voltfin Vantage - Topic: [Memecoins and launches](https://voltfincrypto.com/topics/memecoins) - Chains: BNB Chain - Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is. Many memecoins on BNB Chain start on a launchpad such as four.meme, where a new token sells on a bonding curve until it raises its target. The launchpad then adds the token's liquidity to PancakeSwap, and the token trades there. This dashboard counts launches and graduations every day from the launchpads' own events, and follows how graduated tokens trade afterwards. Read launches and the graduation rate together: many launches with few graduations means buyers are spread across many tokens, while a rising rate means they are concentrating on fewer. Volume on the curves and on PancakeSwap shows where trading happens, and launchpad fees show what the activity earns. ## Blueprint ### Launches Tokens created and graduated each day, and the graduation rate. - **Launches, latest day** (tokens): Tokens created on the selected launchpad on the latest complete UTC day. - **Graduations, latest day** (tokens): Tokens that graduated to PancakeSwap on the latest complete day. - **Graduation rate, last 30 days** (%): Share of the last 30 days' launches that have graduated so far, revised as late graduations arrive. - **Token creators, latest day** (addresses): Distinct addresses that created a token on the selected launchpad on the latest complete day. - **Launches and graduations by day** (tokens): Tokens launched and tokens graduated per day over the selected period. ### Trading Volume on the curves and on PancakeSwap, launchpad fees and the most traded graduates. - **Curve volume, latest day** (USD): Value traded on the launchpad's bonding curves on the latest complete day, from purchase and sale events at oracle prices. - **PancakeSwap volume, latest day** (USD): PancakeSwap volume of graduated launchpad tokens on the latest complete day. - **Launchpad fees by day** (BNB): BNB paid to the launchpad's fee address per day over the selected period. - **Volume on curves and PancakeSwap** (USD): Daily volume split between the bonding curves and the PancakeSwap pools of graduated tokens. - **Most traded graduates**: Graduated tokens with the most volume over the period, with creation and graduation dates, volume, holders and liquidity. Filters: Period (Last 7, 30 or 90 days, or all history); Launchpad (four.meme or any covered BNB Chain launchpad). ## How it will be measured - Launches are TokenCreate events of the four.meme TokenManager contract, and curve trades are its TokenPurchase and TokenSale events, decoded with the ABI of each contract version. - Graduation is the launchpad's LiquidityAdded event, matched to the PancakeSwap PairCreated or PoolCreated event that created the token's pool. - Volume after graduation comes from PancakeSwap v2 and v3 Swap events in the token's pools, valued through each pool's paired asset with Chainlink feeds such as BNB/USD. - Launchpad fees are the BNB transferred to the launchpad's fee address; other BNB Chain launchpads are read the same way from their own factory events. - Every figure names the blocks and logs it was counted from as its receipt. ## Data it needs - `token_launches_daily` (to build): New tokens deployed per chain and launchpad per day, how many reached a DEX pool, and how many were abandoned. - `dex_swaps_daily` (to build): Swap counts and volume per DEX, pool and chain per day, decoded from Swap events, valued with stablecoin legs and oracle prices. - `protocol_revenue_daily` (to build): Fees users paid to each protocol and the part kept by the protocol or its token holders, per protocol and day, including buybacks. - `token_holders_snapshot` (to build): Holder counts, top holders and concentration shares of registry tokens at a pinned block, with contract and exchange labels. - `native_prices_daily` (to build): Reference prices of major assets read from on-chain oracle feeds (Chainlink latestRoundData) at each day's last block, with each round's update time. - Source: four.meme TokenManager 0x5c952063c7fc8610FFDB798152D69F0B9550762b: TokenCreate, TokenPurchase, TokenSale and LiquidityAdded events - Source: PancakeSwap PairCreated and PoolCreated events for graduated tokens - Source: PancakeSwap v2 and v3 Swap events in those pools - Source: BNB transfers to the launchpad's fee address - Source: Chainlink BNB/USD feed at day-end blocks ## Questions ### What is four.meme? A memecoin launchpad on BNB Chain. Anyone can create a token there; it sells on a bonding curve until it raises its target, and then four.meme adds its liquidity to PancakeSwap, where it trades freely. ### How many memecoins launch on BNB Chain per day? It varies with market interest. The dashboard counts every launchpad creation event each UTC day, on four.meme and the other covered launchpads, and shows the history so a busy day can be compared with the past. ### What does graduating to PancakeSwap mean? When a token's bonding curve reaches its target, the launchpad moves the raised BNB and the remaining tokens into a PancakeSwap pool. From then on the token's price is set by that pool rather than by the curve. ### How do BNB Chain memecoins compare with Solana's? Both run on launchpads with bonding curves and graduation to a DEX. The pump.fun dashboard counts Solana launches the same way, so daily launches, graduation rates and volume can be compared on the same definitions. ## Glossary - **four.meme**: A memecoin launchpad on BNB Chain that sells new tokens on a bonding curve before listing them on PancakeSwap. - **Graduation**: When a launchpad token's curve reaches its target and its liquidity moves to a DEX pool. - **PancakeSwap**: A decentralized exchange on BNB Chain, where graduated four.meme tokens trade. ## Related apps - [BNB Chain Daily Transactions and Active Addresses](https://voltfincrypto.com/apps/bnb-chain-transactions) - [BNB Chain Gas Tracker](https://voltfincrypto.com/apps/bnb-chain-gas-tracker) - [Pump.fun Token Launches and Graduations per Day](https://voltfincrypto.com/apps/pump-fun-token-launches) - [New Crypto Tokens Launched Today](https://voltfincrypto.com/apps/new-crypto-tokens-today) - [Memecoin Survival Rate: How Many Launches Last](https://voltfincrypto.com/apps/memecoin-survival-rate) - [Top Memecoins by Market Cap and Chain](https://voltfincrypto.com/apps/top-memecoins-by-market-cap) Build it in Voltfin Studio: https://app.voltfincrypto.com/signup?next=%2F
