We featured a video with Communications Director Matt Powers at the Neo booth to introduce O3 Labs, our wallets and our cross-chain dAPP, O3 Interchange (O3 Swap V2). Remember, O3 started out as a wallet within the Neo ecosystem!

Market Collaboration

  • Go+

Security at O3 Interchange has always been our number one priority. First, we initiated the professional audits of our blockchain security with help from Peckshield and CertiK. PeckShield’s audit is complete while Certik’s is ongoing. Next, we carried out in-depth cooperation with the professional security detection team — Go+ Security to strengthen the risk detection of cross-chain assets from multiple points of view. On the token list on O3 Interchange, you can see a shield button next to each token to help check for more security information. Now, we are organizing a bug bounty campaign with Immunefi!

The O3 Swap and imToken’s Learn and Earn campaign just ended on July 1st, and we will have in-depth cooperations with more premium wallets in the future.
