Our Story

Danor and Alex met in the Neo Tokyo NFT community in 2021, where hundreds of members lost their assets to drainers. Tormented by the losses and the lack of scam detection solutions, they took matters into their own hands and created Sentinel3, the most advanced security solution to detect drainer sites in real-time.
