Paystand, the blockchain-powered B2B payments network, has announced the launch of USDb, a stablecoin designed specifically for commercial-scale enterprise finance. The announcement was made on stage at Bitcoin Las Vegas.

Unlike Tether (USDT) and Circle (USDC) — which together control over 90% of the stablecoin market and were built for crypto-native use cases — USDb targets the accounts receivable, accounts payable, payroll, and treasury workflows that underpin the global economy. It is backed 1:1 by USD reserves and natively deployed on Rootstock, Bitcoin’s leading smart contract sidechain.

N3XT, the blockchain-powered narrow bank targeting institutional B2B payments, has launched the N3XT Digital Dollar (NDD), a bank-issued tokenized deposit backed one-to-one by cash or short-term U.S. Treasuries. The announcement was made at Money 20/20 Asia in Bangkok.

The distinction N3XT draws — and leans on heavily — is that NDD is not a stablecoin. It is issued under a Wyoming Special Purpose Depository Institution charter, making each unit a direct digital representation of a regulated bank deposit rather than a liability of a private issuer operating outside banking law. N3XT operates on a full-reserve model and does not lend, which removes the fractional-reserve risk that has historically complicated institutional adoption of deposit-like digital instruments. Reserve holdings are fully transparent and auditable.
