What happened
Tether is bringing USDT back to Bitcoin, this time via RGB and a uTXO-native issuance model, BeInCrypto reported Thursday. The original Bitcoin-based USDT ran on Omni Layer starting in 2014 and was effectively retired by 2016 as volume shifted to Ethereum and, later, Tron. Thursday's announcement reopens the base-layer path with a different architecture.
Instead of embedding token metadata into Bitcoin transactions the way Omni did, RGB settles state off-chain and anchors commitments into Bitcoin UTXOs. The Bitcoin network itself does not maintain a USDT balance table. Clients do.
That is the entire design point and the source of both the privacy claim and the operational complexity. For users, the practical effect on day one is narrow: a small set of wallets will support receiving and spending USDT whose authenticity is validated against Bitcoin's chain, with Tether as the issuer of record.
Why it matters
USDT supply sits above $120 billion across chains, with Tron and Ethereum carrying the bulk of settlement. A credible Bitcoin rail changes the routing map. It gives OTC desks, remittance corridors, and self-custody users a path that does not depend on Ethereum gas or Tron validator policy.
It also puts dollar liquidity in direct proximity to Bitcoin's fee market, which has been starved for sustained non-ordinal demand since the 2024 halving. The headline looks like a privacy and sovereignty upgrade. The flow picture is more mundane.
