Stablecoin Privacy

Bank of North Dakota, the only state-owned US bank, launched the Roughrider Coin pilot, a permissioned bank-to-bank stablecoin on Solana (Token-2022) with freeze and clawback controls. It runs on the Fiserv Digital Asset Platform, VersaBank USA is the issuer, and Fireblocks provides the infrastructure. It targets North Dakota's 61 FDIC-insured institutions and aims to cut wire costs of $2 to $35 to about $0.01 per transaction. The source does not describe any privacy features.

CoinMarketCap reports that Polygon has launched private stablecoin payments aimed at institutions. The source gives only the headline, with no further details on technology, partners or figures.

Circle and the zero-knowledge chain Aleo launched USDCx, a privacy-enhanced stablecoin, on the Aleo testnet via Circle's xReserve, claiming "bank-level privacy". It is backed 1:1 by USDC, hides transfer amounts, addresses and history from the public, and keeps compliance information available for regulatory review.
