At the same time, the FOURid provides wallet address verification of an individual or an organisation by creating a link between an X.509 user’s online identity and blockchain wallet address.

FOURwaL in your Browser


With a single purpose, the 4thTech wallet (i.e. FOURwaL) serves as a blockchain gateway, a tool for 4thTech platform access. It provides a secure way to connect to the 4thTech blockchain applications (i.e. FOURid, FOURdx, FOURns & others) as it contains a pair of public and private cryptographic keys. A public key allows for other wallets to execute 4thTech services to the desired wallet’s address, whereas a private key enables the decryption of electronic data files and metadata from the sender address.
