Rubic, Symbiosis Bridge, & Boba Network: A Unique Airdrop

6 min readMar 16, 2023

The spring season of cross-promotions and our partners’ airdrops has begun! This time, we’re holding an Airdrop Campaign together with Symbiosis and Boba Network — the Ethereum L2 Optimistic Rollup!

Get ready to grab unique NFTs and participate in a $45,000 Reward Pool!

Rubic x L2 Networks

Our platform enables the swapping of 15,500+ assets across 40+ networks, including Ethereum L2s such as Boba Network, with the best rates, highest liquidity, and transaction speeds — all in one click, thanks to Rubic’s aggregation of 90+ DEXs and bridges.

Rubic aims to accelerate Ethereum scaling and contribute to Layer 2 development. It supports the most popular Ethereum Layer 2 Rollups to date, including Arbitrum, Boba, Optimism, and Metis, with further plans to soon expand to ZK rollups.

Another reason to choose Rubic for moving your tokens across chains is the additional bonuses and airdrops you receive.

That’s why we maintain strong partnerships with L2 Rollups and develop mutual activities to engage users, such as promotions and airdrops for our community.

Now it’s time to get your wallets ready for the first L2 airdrop with Boba Network!

Rubic x Boba

Boba Network is an Optimistic-based multichain Layer 2 scaling solution that aims to unlock the potential of rollup technology, and enable more flexible blockchain communication. The protocol is fully compatible with EVM-based tools and has already deployed multichain support for Avalanche, BNB, Moonbeam and Fantom, supporting lightning-fast transactions and fees anywhere from 40X to 100X less than the respective Layer 1.

By using Boba as a Layer 2 scaling solution, developers can create decentralized applications that can handle a high volume of transactions while leveraging the security and decentralization of the Ethereum network. This can help to address some of the scalability challenges that have been experienced on the Ethereum network, making it more accessible and efficient for developers and users.

Boba Network is the world’s first multichain L2 in the crypto industry and has been integrated into Rubic since August 2022. Along with the Ethereum L2 Solution, Rubic integrated Boba’s L2 solution for BNB Chain and Avalanche. You can read about Boba Network’s integration with BNB Chain here:

Boba Network is powered by Hybrid Compute technology that brings the power of Web2 on-chain, with smarter smart contracts that allow developers to leverage off-chain computing and real-world data to deliver enriched experiences for decentralized applications.

Rubic x Symbiosis

Cooperation is the blood of Web3, and Rubic and Symbiosis represent a true example of partnership, where synergies drive great results.

Symbiosis was integrated into Rubic in July 2022, and it constitutes a very important part of the Rubic ecosystem. Since then, Rubic has generated over $8.8M of cross-chain swap volume to Symbiosis. It’s great that our users trust the Symbiosis bridge, and it’s leading in the number of transactions in Ethereum and BNB Chain versus other Rubic providers.

For the last few months, Symbiosis has been the second-leading Cross-Chain provider on, generating up to 20% of the total trading volume.

Symbiosis helps Rubic conduct secure, fast, and profitable transactions for its users as well as for the integrators of Rubic’s cross-chain tools (SDK/Widget).
