O3 Swap Launches on Neo: Enjoy Token Swaps Between Neo and Mainstream EVM Chains

4 min readJun 20


As the leading open-source community-driven blockchain platform, Neo is pleased to announce the launch of O3 Swap on the Neo N3 blockchain. O3 Labs, the developer community behind O3 Swap, originated on the Neo legacy platform, where O3 Labs built its first wallet. Since then, O3 Labs has grown exponentially, becoming a significant cross-chain liquidity solution. With the launch of O3 Swap on the Neo N3 platform, O3 has strengthened its presence in the Neo ecosystem. This launch marks a new milestone in the strategic partnership between Neo and O3 Labs, giving O3 Labs access to an expanded user base in the Neo ecosystem and bringing increased liquidity, accessibility, and flexibility to NEO token holders.

In 2017, O3 Labs introduced its first application, O3 Wallet, a self-custody wallet, on the Neo legacy blockchain. In 2021, O3 Swap was launched, enabling users to perform seamless cross-chain transactions of native assets within O3 wallet. Since then, O3 Labs has focused on EVM-compatible blockchains. Now, deciding to expand its scope to non-EVM compatible areas has led O3 Labs back to Neo.

The launch of O3 Swap on Neo introduces the fUSDT liquidity pool and aggregates the liquidity from Flamingo Finance, the leading DEX on Neo. This launch facilitates seamless token swaps between Neo and the other mainstream EVM chains already supported by O3 Swap, including Ethereum, BNB Chain, Arbitrum, Polygon, and more. Neo and O3 are currently developing a whitelist for additional cross-chain assets upon the launch of the fUSDT liquidity pool, integrating the liquidity on Flamingo Finance (except for NEO liquidity), thus offering users an enhanced level of flexibility and accessibility.

O3 Swap acts as a liquidity gateway to allow users to easily allocate digital assets across Neo and other O3-supported blockchains. With just a few clicks, users can seamlessly navigate the Neo ecosystem and leverage the interoperability that O3 Swap provides. This enables streamlined asset management and expanded investment opportunities for users.

O3 Labs’ Communication Director spoke on the benefits of expanding functionality on Neo. “O3 Labs is returning to its roots on Neo, to an audience and ecosystem that we’re extremely familiar with,” he said. “We plan to take full advantage of our network within the Neo ecosystem to market and spread liquidity to all of the biggest players in the space.”

Integrating O3 Swap into Neo further strengthens Neo’s comprehensive ecosystem, which already boasts successful DeFi projects such as Flamingo Finance and Forthewin Network. Now Neo and O3 Labs have joined forces to foster liquidity and further bolster the ecosystem’s growth and prosperity.

John Wang, Director of Neo Eco Growth, commented on the impact that the O3 Swap integration is expected to have within the Neo ecosystem. “We applaud the success of O3 Labs, a project that originated on Neo legacy, grew to contribute to the broader blockchain industry, and now has come full circle to become a valued part of the Neo N3 ecosystem. This next stage in our partnership exemplifies the collaborative and supportive spirit at the heart of Neo. As an industry pioneer with both staying power and a track record of continued innovation and evolution, Neo continues to deliver unwavering support to our ecosystem’s projects, nurturing prosperity for these projects and for the blockchain industry as a whole.”

To commemorate this significant milestone, Neo and O3 Swap have curated an array of captivating marketing campaigns and community engagement events with generous rewards, to disseminate the news far and wide, catering to a broader audience, including a cross-chain airdrop in the Neo ecosystem with a prize pool of $2500, and two informative Twitter Spaces with Galxe OATs.
