The Sei Airdrop

The Sei Airdrop

Last updated 09/09/2025

For Sei Community members who participated in Atlantic 2 Testing and the Sei Ambassador Program, please visit the Atlantic Rewards article here.

The Sei airdrop was a first-of-its-kind event, reaching out to every corner of the Web3 universe.

The Sei airdrop is now closed. 

It was a truly “cross-chain” airdrop that recognised pioneering users of blockchain technology from across many ecosystems.

Setting the Scene

Sei is an open-source, permissionless Layer 1 blockchain, specifically designed in response to the fundamental use case of blockchains, the ability to exchange digital assets. As digital assets - from NFTs and Gaming assets to DeFi - continue to grow, so too does the demand for highly performant blockchains. Answering this call, Sei is tailored to be the ideal destination for high-performance, top user experience applications in Web3.

With this in mind, Sei has been built with an emphasis on speed, performance, and technological innovation. It boasts among the fastest time to finality of any blockchain, potentially higher throughput than the theoretical maximum of any Rollup built on Ethereum, and low-latency, all thanks to its use of cutting-edge technologies. These include parallel processing, instant block finality, and novel mechanisms for efficient block propagation and processing.

Going a step further, Sei provides the infrastructure making it possible for anyone with internet access to interact with web3 applications, at a speed faster than a blink. Therefore, Sei not only facilitates efficiency, but it unlocks an entirely new class of Web3 application.

How the Airdrop worked

To participate, whitelisted users were required to bridge qualifying assets into Sei.

The Sei Foundation has worked closely with partners to identify active users across the following blockchains:

  • Solana
  • Ethereum
  • Arbitrum
  • Polygon
  • Binance Smart Chain
  • Osmosis

These chains were selected as their users were responsible for the majority of activity on blockchains during the campaign. Active users on any of these chains had the chance to take part. Eligible tokens included:

Wormhole:

IBC (Osmosis only):

  • ATOM
  • OSMO

Axelar:

  • Ethereum: axlUSDC
  • Arbitrum: axlUSDC
  • Polygon: axlUSDC
  • BNB Chain: axlUSDC

The Sei Foundation offered a simple themed frontend to maintain continuity of experience; however, the underlying bridging protocols were and continue to be completely separate from the Sei Foundation. The Sei Foundation had no influence over the Wormhole and Axelar protocols.
