By eliminating volatile native gas tokens, Stable claims it can deliver sub-1-second finality and consistently low, dollar-denominated costs even during peak network activity. [Stablecoin Newsletter](https://stablecoininsider.org/the-stablecoin-insider-weekly-newsletter/) ### **Key Takeaways** - First major Layer-1 to use a dollar stablecoin (USDT) as its exclusive gas and settlement asset - $1.1 billion in pre-launch deposits and $28 million raised from tier-1 investors - Sub-1-second finality with full EVM compatibility - Fixed-supply governance token offering real-yield staking rewards denominated in USDT - Direct strategic challenge to existing Layer-2 stablecoin issuance platforms [![Stable Layer-1 Mainnet](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2025/12/image-54.png)](https://tether.to/en/) ## **$1.1 Billion in Pre-Deposits Signal Strong Institutional Demand** Since opening phased deposits in October, more than ***10,000 wallets*** have locked ***$1.1 billion*** worth of USDT and other assets ahead of genesis, according to on-chain data verified by Stable’s team. > The figure places Stable among the best-capitalized Layer-1 launches of the past three years. The project previously raised ***$28 million*** in a seed round co-led by Hack VC and PayPal Ventures, with participation from Franklin Templeton, Kraken Ventures, Anchorage Digital co-founder Diogo Mónica, and several other prominent funds. --- ## **Technical Highlights and Consensus Mechanism** Stable operates on StableBFT, a delegated proof-of-stake consensus algorithm derived from [**Tendermint**](https://tendermint.com/) and [**HotStuff**](https://arxiv.org/abs/1803.05069) variants. Independent testnet benchmarks published last month recorded average block times of ***730 milliseconds*** and finality under one second. The chain is fully compatible with the Ethereum Virtual Machine, allowing developers to port existing Solidity smart contracts without modification. Initial integrations include USDT0 (*Tether’s omnichain transfer protocol*), Anchorage Digital for qualified custody, and payment providers Oobit and Orbital.

By operating as an independent Layer-1 with native USDT accounting, the protocol avoids bridge risks, sequencer centralization, and base-layer fee volatility that affect many rollups. Analysts note that Tether’s dominance in [**stablecoin**](https://stablecoininsider.org/) supply gives Stable a unique distribution advantage: ***every USDT holder is already a potential user with zero onboarding friction***.

It is purpose-built infrastructure for the dollar digital economy, fast, predictable, and backed by the largest stablecoin in existence.”** As of press time, pre-market perpetual contracts for STABLE on Binance and Bybit were trading at prices implying a fully diluted valuations between ***$2.8 billion*** and ***$3.4 billion***. The mainnet launch comes at a time of renewed institutional interest in blockchain-based settlement rails, with global stablecoin transfer volume having surpassed ***$27 trillion*** on an annualized basis in 2025, according to The Block Research.
