P2P payments and merchant settlement built around one asset that moves the money and pays for the transaction.

The problem

On general-purpose chains, users must hold a separate gas token (ETH, SOL) just to move stablecoins. That breaks the “send a dollar, receive a dollar” mental model and bleeds conversion at onboarding, where a payer who only has USDT can’t even submit the transfer.

How Stable addresses it

  • USDT0 is both the gas token and the payment asset. A user only ever needs one asset to send or receive. See USDT as gas.
  • Gas waiver lets applications cover gas on behalf of users, enabling a zero-fee UX without the user touching a second token. See Gas waiver.
  • Single-slot finality means settlement is immediate. Once a transfer is in a block, it’s final. See Ethereum comparison.

USDT as gas

Understand the asset that replaces ETH for gas and payment at once.

Gas waiver

See how applications cover user gas through governance-approved waiver addresses.
