Pumpfun Adds Sei Network Support With Built-In Crosschain Bridging for SEI Tokens

Pumpfun (@Pumpfun) $PUMP has launched support for the Sei network (@SeiNetwork) $SEI, allowing users to trade Sei tokens inside its app. Crosschain bridging is also available within the app, so users do not need to leave the platform to move funds.

The integration could give tokens from the Sei ecosystem greater exposure to Pumpfun's user base.

Part of a Wider Multichain Push

Pumpfun built its business on Solana and became a popular platform for launching and trading memecoins. The Sei addition follows a broader shift toward a multichain model, as the app has extended trading beyond its native launches.

The move fits a longer trend of widening the app's scope. The Block reported that Pumpfun added support for tokens from rival launchpads such as Raydium and Meteora, along with Wormhole-bridged wrapped Bitcoin and Ethereum. Pump said at the time that users increasingly want to trade and hold more without leaving the app.

Sei is not new to the Pump ecosystem. PumpSwap, the platform's native decentralized exchange, was previously set to support partner tokens including $SEI, alongside PENGU, APT and JUP.

What Sei Offers

Sei is described by developer platform thirdweb as an EVM-compatible, Cosmos-based Layer 1 designed for trading, with sub-second finality and parallelized execution. $SEI is used for fees, staking and governance on the network.

Separately, Coinfomania reported that Sei Network passed SIP-6, enabling the Autobahn upgrade for Sei Giga, which is aimed at supporting onchain trading functions such as order placement and cancellation.

Tokens traded on Pumpfun can carry high risk, and selling depends on available liquidity in a given market. Users should assess individual tokens before trading.
