Broker-dealer and token-sale compliance contracting firm TokenSoft has launched the beta version of its securities token wallet, Knox. The wallet can hold ERC-20, ERC-1404, DS-20 (Securitize), ST-20 (Polymath), Harborβs R tokens, Bitcoin ($BTC), and Ethereum ($ETH), although the main focus remains on security tokens. According to TokenSoft co-founder Mason Borda, the self-custody wallet is a "key piece of infrastructure that the industry has ignored up until now."
