Discontinuation of XAUm Support on Polygon, HashKey Chain, and Tron
Publication Date: August 7, 2026 Completion Date: August 7, 2026
1. Summary
Matrixdock is consolidating the multi-network deployments of XAUm (Matrixdock Gold) to concentrate liquidity and simplify cross-chain operations.
As of August 7, 2026, the XAUm deployments on the following three networks have been discontinued:
Polygon
HashKey Chain
Tron
No XAUm holders are affected, and no user action is required.
Following this consolidation, XAUm continues to be fully supported on Ethereum, BNB Chain, Solana, Sui, Stellar, and Plume for minting, redemption, and cross-chain transfers. The physical gold reserves backing XAUm, its 1:1 redemption mechanism, and its Proof of Reserves are unaffected by this consolidation.
Matrixdock has ceased all issuance and operations on these three networks. Because a deployed smart contract cannot be deleted, these contracts will remain visible on-chain; they are permanently retired, and Matrixdock will not use them again.
