Paxos Standard (or Paxos) is the Stablecoin that had the highest increase in the number of on-chain wallets this year. Paxos Standard’s accumulated wallet count (wallets with a token balance bigger than 0) stats recorded a 53% increase after this year.

According to Xangle, the crypto disclosure platform, Paxos signed a partnership with Huobi allowing HUSD, the Huobi-USD stable coin, to be deposited and withdrawn from the Paxos Wallet, given that the user is not a US citizen. The Paxos Wallet also supports conversion between PAX, BUSD, and HUSD with a 0% fee. The Paxos Trust Company will offer custody services for HUSD.
USDT, USDC, TrueUSD, DAI were other stablecoins that showed promising on-chain wallet growth, with 20, 19, 10, and 1% respectively.
