gasUSDT & USDT0 on Stable

The Stable Blockchain is dedicated to supporting the USDT stablecoin, and both gasUSDT and USDT0 serve as core components of its ecosystem.

  • gasUSDT: On Stable, gasUSDT functions as the native gas token. Users pay transaction fees in gasUSDT when transferring tokens, interacting with smart contracts, or executing any on-chain operations.
  • USDT0: USDT0 is an ERC-20 token designed for seamless integration with DeFi protocols and smart contracts within the Stable ecosystem. Users can easily wrap and unwrap between gasUSDT and USDT0.

This dual-token structure mirrors the Ethereum network’s relationship between ETH and wETH. Just as ETH is used for gas and wETH for ERC-20 interactions, gasUSDT acts as the native asset on Stable, while USDT0 ensures compatibility with smart contracts.

Access to Deep Liquidity from Day 1

Thanks to USDT0’s OFT standard, users can easily onboard their USDT0 holdings from other networks to Stable via LayerZero. This enables Stable to access deep USDT liquidity from day one.

To acquire gasUSDT as the native gas token, users have two options:

  • Free Unwrap: Convert USDT0 to gasUSDT on Stable with no fee.
  • Destination Gas Conversion: During the LayerZero bridging process, users can enable the “destination gas convert” feature to automatically receive gasUSDT (native gas token) alongside their bridged USDT0.

This streamlined onboarding mechanism ensures that users can interact with Stable immediately, without friction, and with access to native gas.

Safety Measures for gasUSDT

Most users primarily use USDT0 to interact with various applications within the Stable ecosystem. gasUSDT serves only as the gas token used to pay transaction fees.

To prevent user confusion and accidental transfers of gasUSDT to other networks or CEXs, gasUSDT transfers are restricted on Stable. Users are expected to use USDT0 for a wide range of activities within the ecosystem, including sending assets to other networks and CEXs.
