Part 1: What is Stable? Why is it needed? Stable = A blockchain dedicated to stablecoin payments Stable is an L1 blockchain optimized exclusively for stablecoin payments. It consists of a main chain called StableChain and a wallet app called StablePay. It focuses solely on everyday payments, remittances, and corporate payments, rather than trading or DeFi. Problems with existing blockchains Gas fees are a roller coaster ride - When the network is congested, fees can jump tenfold. Buying a coffee can cost more in gas than you can afford. Can this really be used for real-world payments? Unpredictable transaction order - You never know when your transfer will be processed, and urgent transfers are a game of luck. This is what businesses hate the most. Inefficient because it's a general-purpose blockchain - Ethereum was built for DeFi, NFTs, and gaming, but payments don't need such complex features. Simplicity, speed, and reliability are key. Stable's solution: Predictability is key. - Make costs, settlement times, and user experience predictable. Gas fees are fixed and settlement times are guaranteed. Native stablecoin design - Designed from the ground up around USDT, using gUSDT as the gas token (scheduled to transition to USDT0 in 2026). Payments can be made directly in USDT without conversion. Payment-specific architecture - Achieves sub-second block times with the StableBFT consensus algorithm and can process 10,000+ TPS. Single-slot finality ensures immediate transaction finalization. EVM compatibility - Existing Ethereum tools can be used, making migration easy for developers. Why USDT? USDT is the world's leading stablecoin, with $180 billion in circulation and 350 million users. Its trading volume is higher than Visa's, which is why everything is designed around USDT. Consider it the foundation of the foundation.
