Memecoin launchpads make it easy to create a token and push liquidity straight to a decentralized exchange. On the Sui blockchain, two no-code choices stand out: DoubleUp.fun and 7k.fun. Both platforms promise fair launches and hands-off smart contract deployment, yet they differ in community support, bonding curve requirements, and safety tools. The guide below breaks down those differences so you can decide where you will launch your next memecoin.

Background and Founding Dates

DoubleUp.fun went live in 2023 as one of the first public launchpads to tap into Sui’s fast, low-fee features. A year later, 7k.fun entered the scene in 2024 and positioned itself as a lighter and creator-friendly alternative. Both platforms keep things no-code. This means users just have to specify the memecoin’s name, symbol, description, and image/avatar, and the platform will create the memecoin automatically.

Customer Service

DoubleUp maintains Telegram and Discord channels where you can get help if you encounter any issues or if you have questions. 7k.fun, on the other hand, currently offers no public support channel. For experienced builders that may not matter, but first-timers could appreciate the real-time help found in DoubleUp’s customer support channels..

Fees

Neither platform has published their fees publicly, mainly because the Sui gas fee is dynamic. We recommend checking the current network charges before deploying.

Bonding Curve Targets

DoubleUp.fun requires a minimum of roughly 5,400 SUI (about $20,000) before the memecoin is migrated to a decentralized exchange and becomes tradeable. 7k.fun comes in lower at 4,000 SUI (around $15,000). The lower bar at 7k.fun can make the difference between launching now or waiting, but you may not feel the gap if you have a deep pocket.

Supported DEXs

Once a curve caps out, liquidity migrates automatically to a decentralized exchange. DoubleUp migrates tokens to Bluefin, Cetus, Aftermath, or FlowX. This gives you the freedom to launch your memecoin on a platform with the most users or the lowest fees. 7k.fun works with FlowX V2, Bluefin, and Aftermath, but not Cetus. For traders who prefer Cetus liquidity pools, that limitation could influence the launchpad choice.

Fair Launch Standards

Both launchpads use a fair-launch format: no private sales, no discounted early rounds, and no hidden wallets front-running the curve. The contract starts at a fixed floor price, and everyone buys on equal terms.

Anti-Rug Pull Measures

Rug pulls (when founders dump tokens on day one) are the bane of every memecoin. DoubleUp.fun has yet to develop a feature that locks a percentage of the memecoin supply. 7k.fun already enforces an optional lock: creators can seal up to 50.5% of the supply for three days. While three days won't solve every scam scenario, it does demonstrate at least a short-term barrier against instant dumps.

Overall User Flow

Creating a memecoin on either launchpad does something like this:

• Connect wallet: Slush Wallet or another compatible extension.
• Add funds to the wallet: Buy SUI to cover the network fees.
• Create the memecoin: Input the name, symbol, description, upload an image, and choose a mitigation target.
• Promote: Share the curve link on social media so buyers can join the initial round.

Which Launchpad is a Better Fit for You?

Because both platforms run on the same Sui infrastructure, the network speed, and basic user experience feel alike. The real choice boils down to customer support, minimum curve size, selectable DEX destinations, and whether that optional anti-rug feature adds enough peace of mind for your holders.
