PANews reported on January 30 that according to Coindesk, Dutch bank ABN AMRO and German regulatory platform 21X completed a joint proof of concept (PoC) on the Polygon Amoy test network, successfully listing trading pairs of tokenized assets and electronic currency tokens. The test used 21X's on-chain order book smart contract to support the exchange of tokenized cash and tokenized assets in a single transaction. As a company focusing on blockchain securities exchanges, 21X has been approved by the German financial regulator BaFin in December 2023.
