The dev team at Hex Trust placed 2nd at the SAFU Pre-Hackathon in Hong Kong & in the Top 6 Finalist of the Final SAFU Hackathon in Singapore. 🎉

From 19–22 Jan 2019 Binance held a two-day hackathon during the Binance Blockchain Week. 20+ teams were selected to showcase their applications that aim to identify cryptocurrency wallet addresses which are involved in scams or frauds.

Is the transaction address you are sending your crypto to SAFU?”

With the theme ‘Query Platform for Address Security: Is the transaction address you are sending your crypto to SAFU?’, the Binance SAFU Hackathon encouraged long-term, sustainable growth of the blockchain industry, calling top developers from around the world to build a safer community where users are protected from scams, hackers and money laundering.

The announcement of Hex Trust being placed in the top 6 teams


The team developed a decentralized network for address verification and scoring, called “Armadillo”. In the center of the application is a powerful browser extension, that checks for dangerous addresses, powered by a crowd intelligence network.

Focusing on unique user experience & interface design the team created a product that is easy to use for both the general public and industry experts.

Using the browser plugin, individuals have a seamless experience as they are not required to copy and paste wallet addresses into a specific website; they can see the addresses directly highlighted on their screen with basic information about that address.

In addition to usual statistical and machine learning methods, our team used crowd sourced intelligence and identity verification to improve the reliability of scores. “Armadillo” also acts as a certification authority for wallets, exchanges and any businesses that generate addresses, tagging them as certified addresses. The plugin provides transparency storing address verification and scoring data on EOS blockchain. “ARMA” ERC-20 tokens are used for incentivizing positive participation and reputation staking. Lastly, the application provides an open API to certify addresses and querying of address scores.


The team combines engineers and designers from different nationalities and technology backgrounds: Germany, Poland, South Korea, the United States, and Hong Kong.
