Data verified on unchanged since the sources
Worth it if you're building stablecoin payments and want an L1 with USDT as native gas, sub-cent fees and sub-second finality.
Avoid it if you're an end user (this is B2B infrastructure) or don't want to bet on an early-stage project built entirely around the Tether/USDT ecosystem.
Stable is a Layer 1 blockchain dedicated to stablecoin payments, backed by Bitfinex and Tether, using USDT as the native gas token with sub-second finality and fees below one cent. It raised $28M in a seed round co-led by Bitfinex and Hack VC and launched its mainnet with over $1.1 billion (mostly USDT) pre-deposited across 10,000+ wallets. Alongside the mainnet it released the native STABLE token for network governance and security.
