What Is Stable Chain?

Updated August 2026

Stable (often called "Stablechain") is an EVM-compatible layer-1 built around one radical idea: the dollar is the gas. Every fee on the chain is paid in USDT0, Tether's omnichain dollar. No volatile gas token, no "not enough ETH for gas": you fund a wallet with dollars and everything just works.

Who's behind it

Stable raised a $28 million seed round co-led by Bitfinex and Hack VC (July 2025), with Franklin Templeton, PayPal Ventures and Castle Island Ventures participating. Paolo Ardoino, CEO of Tether, is a strategic advisor. This is as close to an "official USDT chain" as exists: the entities that issue and custody the world's largest stablecoin are directly invested in its success.

Why activity is exploding

Stable was designed for payments: instant, dollar-denominated settlement. But wherever a new chain gets users, liquidity and a distribution story, a trading scene follows. Through 2026 Stable has developed exactly that: new tokens launching daily, native DEXes like DYORSwap, and the major Telegram trading bots arriving on the chain. The combination of dollar gas (your P&L is in dollars, always legible) and sub-second finality (trades fill instantly) happens to make it an unusually comfortable chain to trade on.

The on-chain numbers back it up: tens of millions of transactions processed and billions in USDT0 on-chain within the first year (live figures on Stablescan).

What makes it different from other L1s

• No gas token speculation layer. On most chains you must hold a volatile asset just to transact. On Stable, the money and the gas are the same dollar.
• Cheapest operation = sending dollars. A simple USDT0 transfer costs 21,000 gas, the chain's cheapest transaction by design. It's built to move money first.
• Backed by the USDT ecosystem itself: not a fork chasing a narrative, but infrastructure built by the people who run the largest stablecoin.

The STABLE token

The chain has a governance token, STABLE, with a fixed supply of 100 billion (40% ecosystem, 25% team, 25% investors, 10% genesis). It's used for governance and validator delegation, but note that you never need STABLE to use the chain. Gas is USDT0, full stop.
