Cross-Chain Airdrop Guide: Comprehensive Strategy for SEI Airdrop Targeting Users across Multiple Major Public Blockchains

Communication and Sharing

The SEI airdrop is a unique event that encompasses every corner of the Web3 universe. This is a truly "cross-chain" airdrop that acknowledges pioneering users from many ecosystems. In 2023, most mainstream blockchain users may be whitelisted and eligible to participate.

Background Overview

Sei is an open-source, permissionless Layer 1 blockchain designed specifically for the fundamental use case of exchanging digital assets on the blockchain. As the growth of digital assets, from NFTs and games to DeFi, continues, there is a growing demand for high-performance blockchains. In response to this demand, Sei focuses on becoming the ideal infrastructure for high-performance, top-tier user experience DApps in Web3.

To achieve this, Sei has been optimized for speed, efficiency, and technological innovation. It boasts the fastest final block confirmation time of any blockchain, potential throughput potentially higher than any theoretical maximum value on Ethereum's rollups, and incorporates cutting-edge technologies for low latency. This includes novel mechanisms such as parallel processing, instant block finality, and efficient block propagation.

Furthermore, Sei provides the infrastructure for anyone with internet access to interact with Web3 applications at super-fast speeds, enabling near-instant interactions. Thus, Sei not only increases efficiency but also unlocks an entirely new category of Web3 applications.

How the Airdrop Works

To participate, whitelisted users must bridge eligible assets to Sei. The Sei Foundation works closely with ecosystem partners to identify active users on the following blockchains:

Solana Ethereum Arbitrum Polygon Binance Smart Chain Osmosis

Users on these chains have participated in activities across a majority of today's blockchains. Active users on these chains may qualify for the airdrop.

Airdrop Claim Process

The first step is to set up a Sei wallet. You can use either the Fin Wallet or Compass Wallet during the launch. If you're installing these wallets for the first time, follow the instructions and remember to store your mnemonic phrase securely. If you've already installed these wallets on the Atlantic-2 testnet, make sure you install the latest version that supports the Pacific-1 mainnet.

Simply follow the instructions on the "Airdrop" tab to link your existing off-chain wallet to a Sei wallet address and bridge any listed tokens on the Sei Cross-Chain Bridge page.

The Sei Foundation provides a simple themed frontend to maintain the continuity of the experience, but the underlying bridging protocols are entirely independent of the Sei Foundation. The Sei Foundation has no impact on the Wormhole and Axelar protocols. You can learn more about their technology and how to implement bridging with Sei.

Eligible tokens include:


Ethereum: USDC, ETH, WBTC Arbitrum: USDC.e (arbUSDC) Polygon: USDC (maticUSDC) Optimism: USDC (opUSDC) Solana: USDC (solUSDC) BNB: USDT (bnbUSDT)

IBC (Osmosis only):



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


Frequently Asked Questions

  1. My cross-chain transaction is pending, how do I know if there's an issue?

Cross-chain transactions are entirely handled by Wormhole or Axelar, depending on the specific asset. You can visit the Wormhole Discord or access Axelar Support for more information. Note: When bridging from Ethereum, transactions may take up to 30 minutes to reach Sei. This delay is due to the operation of the Wormhole and Axelar bridging protocols and doesn't reflect Sei's finality time or performance. For example, when assets are being transferred from the original chain (in this case, Ethereum), they are being processed through the bridging protocol (in this case, Wormhole).

  1. Are there any restrictions on transferring assets into or out of Sei?

Any restrictions stem from the parameters set by Wormhole and Axelar. The Sei Foundation has no control or say in this process. Wormhole's standard procedure is to start with preset daily and high transaction limits on the new blockchain, which will apply to bridging in and out of Sei – please note this, and be aware that these limits will increase over time. Axelar also has limitations on bridging axlUSDC to or from Sei, with a limit of $3 million every 6 hours.

  1. How many times can I claim the airdrop?

Each external whitelisted address associated with a Sei wallet can claim the airdrop only once.

  1. Can I attempt to claim the airdrop again using the same Sei wallet / external wallet?

No, you cannot.

  1. Does linking my wallet require sharing my private key?

No, it doesn't. Your private key will never be shared or revealed during this process.

  1. I participated in Sei's Atlantic testnet and/or Ambassador Program. Where can I find my rewards?

Please refer to the "Sei Atlantic Rewards" for more information.
