Sei tokens now trade inside Pumpfun
Pumpfun has added support for the Sei network, letting users trade Sei-based tokens without leaving the app. The platform also added crosschain bridging inside the app. That means users can move funds and trade in one place, instead of jumping between wallets and separate tools. For Sei projects, it is a chance to reach Pumpfun’s existing user base. That audience is large, though it is also used to fast-moving and sometimes risky memecoin trades.
A wider multichain push
Pumpfun started on Solana and became known for launching and trading memecoins. The Sei addition is part of a wider move toward multichain support. The app has already extended beyond its own launches. The Block reported that Pumpfun added support for tokens from rival launchpads like Raydium and Meteora, plus Wormhole-bridged wrapped Bitcoin and Ethereum. At the time, Pump said users want to trade and hold more assets without leaving the app. That logic seems to apply here too. Sei is not completely new to the Pump world. PumpSwap, the platform’s own decentralized exchange, had been set to support partner tokens including SEI, alongside PENGU, APT and JUP.
What Sei brings to the table
Sei is an EVM-compatible, Cosmos-based Layer 1 built for trading. Developer platform thirdweb describes it as having sub-second finality and parallelized execution. SEI is used for fees, staking and governance on the network. Separately, Coinfomania reported that Sei passed SIP-6, which enables the Autobahn upgrade for Sei Giga. That upgrade is aimed at onchain trading functions such as order placement and cancellation. I think this helps explain why Pumpfun might see Sei as a useful fit, though it does not remove the risks.
Risk still comes with the trade
Tokens traded on Pumpfun can be highly risky. Selling depends on liquidity in a given market, and thin markets can move quickly. Users should look at each token before trading, not just the network it sits on. The Sei support may bring more activity and more choices, but it does not make every token safe. For now, the change is another step in Pumpfun’s shift from a Solana-only launchpad to a broader trading app.
