is pleased to announce it will be supporting XSGD, the Singapore dollar stablecoin that is currently the world’s largest non-USD stablecoin by market capitalisation, and XIDR, the Indonesian Rupiah stablecoin issued by StraitsX.

StraitsX will leverage Copper’s industry-leading institutional custody to manage its digital asset holdings. 

Each XSGD and XIDR is backed by one Singapore Dollar and one Indonesian Rupiah respectively. With XSGD and XIDR, holders can make near-instant, low-cost transfers of XSGD, 24/7 on the Ethereum blockchain.

Copper’s infrastructure is underpinned by multi-award-winning custody and an Aon brokered crime insurance policy. Copper’s secure digital asset custody solution uses Multi-Party Computation (MPC) technology whereby key shards are created separately and in isolation, largely eliminating the risk of key exposure in online transactions.

Over 400 institutions use Copper as a custodian for their crypto assets both for the paramount security provided by Copper and for the wide range of supported tokens, which currently stands at over 450. 

Aymeric Salley, Head of StraitsX, said, “With XSGD becoming the world's largest non-USD stablecoin and the launch of XIDR, we’re excited to expand the XSGD and XIDR ecosystem with Copper and leverage their secure custody solution to further enhance the StraitsX platform.“ 

Takatoshi Shibayama, Head of Business Development – Asia,, added: “We’re delighted to announce our support for StraitsX as their institutional custodian for the world’s largest non-USD stablecoin, XSGD, and newly launched stablecoin XIDR. Their commitment to growing the decentralised finance ecosystem in Asia with progressive launches of these stablecoins to grow the adoption of digital assets, align with our vision of enabling safe and secure digital asset engagement globally.”
