What is Stable? Stable is a stablecoin-focused Layer 1 blockchain built for USDT-denominated payments, settlement, and financial applications. It is EVM-compatible, uses USDT0 as its native gas and settlement asset, and is designed to provide low-cost transactions with sub-second finality.
Core technology and use cases
Stable uses StableBFT, a customized delegated Proof-of-Stake consensus system built on CometBFT. Its Stable EVM supports Solidity, Foundry, Hardhat, ethers.js, viem, and standard Ethereum JSON-RPC tools. Stable Mainnet uses chain ID 988, while USDT0 provides both transaction fees and payment value through an ERC-20 interface.
The network targets peer-to-peer transfers, recurring payments, invoice settlement, payroll-related payments, cross-border remittances, merchant payouts, and treasury transfers. Its EVM compatibility also supports decentralized exchanges, lending markets, escrow contracts, payment applications, StableEarn, and Morpho vaults. Stable’s x402-related infrastructure extends the payment model to APIs and AI agents, allowing USDT0 payments to be included in HTTP requests.
Stable Mainnet launched on 8 December 2025. The network initially used gUSDT for gas, but the v1.2.0 upgrade in February 2026 replaced it with USDT0. The live v1.8.0 release added performance features including Block-STM execution, Selective RecheckTx, MemIAVL, two-dimensional nonces, and guaranteed blockspace.
Who is behind Stable and where is it based?
Stable’s public materials identify Joshua Harding as a co-founder and CEO in the 2025 funding announcement. Its leadership materials identify Brian Mehler as CEO and Sam Kazemian, founder of Frax, as CTO, indicating that leadership roles changed or expanded. The full engineering team has not been publicly confirmed. Mehler is based in Dubai, while Head of Marketing Eunice C. is based in Hong Kong.
LinkedIn lists the company as founded in 2024, but official materials do not clearly confirm a founding year. The project emerged publicly from stealth in 2025, announced a $28 million seed round on 31 July 2025, and launched its mainnet and STABLE token on 8 December 2025.
Stable’s Terms of Service identify Stable Foundation as a foundation company incorporated in the Cayman Islands. The whitepaper separately refers to a private-interest foundation established under Panamanian law, and the relationship between the two entities is not explained in the available sources. A separate operating headquarters has not been conclusively confirmed.
STABLE tokenomics and security
The fixed total supply is 100,000,000,000 STABLE, with 26,801,528,463 STABLE in circulation. The market snapshot records a price of $0.02833, market cap of $759.38M (rank #120), and 24h volume of $9.12M. The all-time high is $0.04324, and the current price is 34.47% below it.
The allocation is 25% to investors and advisors, 25% to the team, 40% to the ecosystem and community, and 10% to the genesis distribution. Genesis tokens were fully unlocked at mainnet launch. Eight percent of the ecosystem allocation was initially unlocked, with the remaining 32% scheduled for three-year linear vesting. Team and investor tokens have a 12-month cliff followed by linear vesting over 48 months. No separate ongoing inflation schedule or confirmed STABLE fee-burn mechanism is documented.
STABLE supports governance, delegated staking, and network coordination. Validators distribute part of USDT0 gas revenue to stakers. StableBFT provides deterministic finality and is designed to tolerate the failure or malicious behavior of up to one-third of validators. Its planned Autobahn upgrade would introduce a DAG-based consensus design.
Partnerships and development
Reported integrations include Tether and USDT0, PayPal and PYUSD, Bitfinex, Oobit, Anchorage Digital, Orbital, WalletConnect, Cactus Custody, Chainalysis, Philidor Labs, and Mesh Alliance. Stable also announced a $28 million seed round led by Bitfinex and Hack VC, with participation from several investment firms.
The roadmap covers higher-throughput transfer aggregation, guaranteed institutional blockspace, confidential transfers, expanded custody and off-ramp support, and Autobahn consensus. Stable reported more than 4,600 smart contracts, 42,000 active addresses, 860,000 transactions, and 150+ ecosystem partners in a February 2026 development update.
