STBL has integrated Wormhole’s Native Token Transfers (NTT) standard to bring USST, its USD-pegged stablecoin, natively to Ethereum and BNB Chain. This multichain expansion allows their RWA-backed stablecoin to expand its reach while preserving its unique protocol mechanics and unified liquidity.

What is STBL?

STBL is a decentralized non custodial protocol introducing the next evolution of stablecoins. Instead of bundling stability yield and governance into a single token STBL cleanly separates them across three distinct tokens allowing for greater flexibility and utility:

  • USST is a USD pegged stablecoin minted by locking tokenized RWAs as collateral. USST is designed to be liquid stable and freely usable for payments trading or as a reserve asset.
  • YLD is a yield claim token. When USST is minted a corresponding YLD token is created. This token represents the right to claim the yield generated from the underlying collateralized RWAs.
  • STBL enables protocol governance and participation in protocol mechanisms.
What is NTT?

Wormhole’s NTT (Native Token Transfers) is an open and composable framework for seamlessly transferring native tokens across blockchains while preserving their intrinsic properties. NTT is already powering natively multichain tokens for leading projects such as Sky, Lido, WalletConnect, RedStone, and Wormhole's W token, demonstrating its industry-wide impact and reliability.

Why NTT?

By leveraging Wormhole’s NTT standard, USST ensures STBL can scale seamlessly across Ethereum and BNB Chain, eliminating liquidity fragmentation. With NTT, projects maintain full control over their tokens’ behavior on each chain, including aspects such as customizability, metadata management, and ownership or upgradeability. This ensures compatibility with any token standard or governance system, offering unparalleled flexibility and adaptability.

Take Your Token Multichain with NTT

NTT is already being used by some of crypto’s most systemically important assets, like Lido’s wstETH and Sky’s (formerly Maker) USDS, to unify users and liquidity.
