Protocols

Stable is an application-specific Layer 1 blockchain co-launched by Bitfinex and Tether. Its core operational mechanism involves the deep integration of USDT into the network’s base layer, serving directly as the native Gas token for transaction fees. By introducing USDT0 assets based on the LayerZero OFT standard, the protocol enables seamless cross-chain transfers across multiple major public chains and utilizes its proprietary StableBFT consensus algorithm to provide sub-second transaction finality. Furthermore, Stable is a pioneer in natively supporting the EIP-7702 protocol at the L1 level, granting traditional Externally Owned Accounts (EOAs) programmable smart contract capabilities and establishing a high-performance, ultra-low-friction stablecoin payment foundation.
