OKX users will now be able to scan Singapore’s national unified payment QR code (SGQR) to use the two stablecoins for daily transactions through the OKX Pay service. Every OKX Pay transaction will be executed as a blockchain transfer using the purpose bound money (PBM) framework, which applies programmable logic to ensure compliant and conditional settlement. Trading of the XSGD stablecoin also began on OKX’s competitor exchange Coinbase on Tuesday. The XSGD stablecoin is also already integrated with Alipay+.
