Pay in SOL, USDC, or another listed token. Non-USDC tokens swap to USDC first, then mint xGLDB. Swap routing is provided by Jupiter. Checkout mints a digital asset, not physical metal.
Enter either amount. xGLDB is issued in whole units; a SOL budget rounds down to whole units and transfers only the exact quote.
Payment and mint settle in one transaction
Protocol-wide tape for asset mints (xGLDB, xGLDD, xSLVD, xGOLD, xSLVR), not a single wallet. Signatures only, no off-chain names or custody account numbers. Kind classification (mint vs. transfer) is a later increment — every row today is Real activity.
