Stable is an institutional-grade blockchain, dubbed a 'Stablechain,' specifically designed for stablecoins like USDT, aiming to provide reliable infrastructure for the real economy. Its mission is to address current stablecoin infrastructure challenges such as unpredictable costs, enterprise integration gaps, poor user experience, and exclusion of users due to high remittance costs.

FAQs

What is Stable's chain ID and gas token?

How do I send USDT on Stable?

Send a plain value transfer with the amount in 18-decimal units; it costs 21,000 gas, about $0.00002 at the 1 Gwei base fee. Or call transfer(to, amount) on the USDT0 contract with a 6-decimal amount for approve and transferFrom flows. Zero-gas transfers are not a protocol default: they require a governance-registered gas waiver that wraps the user's signed transaction. The Stablechain RPC guide has the ethers and viem examples.
