Tech overview

You can deploy Solidity or Vyper contracts on Stable today using Hardhat, Foundry, or any standard EVM tooling, and your contracts work without modification. What changes: gas is paid in USDT0, transactions reach single-slot finality, and every layer of the stack is tuned for stablecoin throughput.

StableBFT

Stable Blockchain leverages StableBFT, a customized PoS consensus protocol built on CometBFT, for high throughput, low latency, and strong reliability across the network.

Stable EVM

Stable EVM is Stable's Ethereum-compatible execution layer. Standard Ethereum tools and wallets interact with the chain unchanged. A set of precompiles bridges Stable EVM to the Stable SDK, letting EVM smart contracts call into core chain logic atomically.

StableDB

Stable fixes a major blockchain bottleneck: slow disk storage after each block. It separates state commitment from storage so blocks process without delay. MemDB and VersionDB, powered by mmap, keep recent data in memory while older data is stored efficiently, boosting overall throughput.

High performance RPC

A slow RPC layer ruins the user experience even on a fast chain. Stable addresses this with a split-path architecture that separates operations by function, deploying lightweight, specialized RPC nodes for faster response times.
