AB

AB is a heterogeneous blockchain network focused on stablecoins and payments. Its technical architecture consists of a base technology layer, a super exchange layer, and an application layer: the base layer provides an Ethereum-compatible EVM chain supporting standard smart contracts and developer tools; the super exchange layer enables cross-chain asset interoperability among the core chain, sidechains, and major public chains via AB Connect; the application layer implements fee abstraction through the UTP protocol, allowing users to pay transaction fees with certified assets (e.g., AB, USD1) without needing native tokens, while the protocol automatically handles on-chain gas settlement. The EVT protocol supports asset variability, encryption, traceability, and RWA tokenization. The network has a block time of approximately 3 seconds, requires 20 block confirmations for transaction finality, and uses 18 decimal places for token precision. Developers can connect via official RPC endpoints to the mainnet (ChainID 36888) or testnet (ChainID 26888), and refer to the open-source code for node deployment.
