XSGD is a digital currency designed to maintain a 1:1 value with the Singapore Dollar (SGD). It provides an efficient way for global users to get on-chain and hold digital assets without the high costs of traditional currency conversion.
What is XSGD structurally?
XSGD is a fiat-backed stablecoin issued by StraitsX, a major payment institution licensed by the Monetary Authority of Singapore (MAS). Every XSGD token is collateralized by one Singapore dollar held in reserve at regulated financial institutions.
The asset is designed for high interoperability and is available as a native token on several major blockchains, including Ethereum, Polygon, Solana, Avalanche, and Base. This multi-chain approach allows users to choose the network that optimally fits their cost and speed requirements.
How it works in practice
StraitsX utilizes active market making to ensure that XSGD stays anchored to real-world FX rates rather than volatile speculation. The goal is straightforward: provide passive liquidity so users can buy or sell at prices that closely reflect the real SGD/USD exchange rate, with minimal slippage and sufficient depth on both sides of the order book.
StraitsX automates the placement of bids and asks around the prevailing FX reference rate, slightly below and above parity, and replenishes these orders if they are executed or whenever the underlying FX reference rate changes. This two-sided liquidity allows participants to transact efficiently without needing to wait for a perfectly matched counterparty.
When a user trades against the order book, the market maker absorbs the imbalance and then restores inventory through real-world settlement flows. When XSGD/USDC trades above SGD/USD in the secondary market, arbitrage opportunities encourage participants to acquire XSGD through the primary market and sell it on the secondary market, increasing supply and bringing the price back toward parity. Conversely, when XSGD/USDC trades below SGD/USD, participants can buy it on the secondary market and redeem it in the primary market, reducing supply and pushing the price toward parity.
Fees and pricing mechanics
StraitsX typically offers zero fees for depositing and withdrawing SGD through supported Singaporean bank accounts. This direct 1:1 conversion model is intended to minimize the “friction” of moving between traditional bank deposits and on-chain assets.
On-chain transfers incur network fees, which vary significantly by blockchain. Because XSGD is supported on low-cost networks like Base and Solana, users can settle transactions in seconds for a fraction of a cent, significantly outperforming traditional international banking rails.
Limits, eligibility, and availability
XSGD is accessible to verified individual and business users who pass StraitsX’s KYC and AML screenings. Its availability on public blockchains like Base makes it globally tradeable and suitable for use in decentralized finance (DeFi) protocols.
The platform provides simple APIs and SDKs for developers, facilitating its integration into merchant payment systems. Active market making builds ecosystem trust by keeping stablecoin order books predictable and reliable for all participants.
Tradeoffs, risks, and limitations
The primary tradeoff of XSGD is its centralized issuance model, which requires users to trust StraitsX to maintain full reserves. While the asset is designed for stability, it is subject to the solvency of the financial institutions holding its reserves.
XSGD tokens are not considered legal tender and do not carry the same government protections as traditional bank deposits. Furthermore, while market making helps maintain parity, a single large trade can temporarily shift on-chain prices away from their off-chain reference during periods of thin liquidity.
Without active market making, stablecoin order books would be more fragile. Prices would swing sharply with each large trade, liquidity would thin out during periods of stress, and stablecoins would become less reliable as representations of real-world currencies. By providing consistent two-sided liquidity and maintaining close alignment with off-chain reference rates, market making supports market integrity, improves user experience, and strengthens trust in the stablecoin ecosystem as a whole.
