What is Stable?

Stable is defined as the first Stablechain, a Layer 1 blockchain where stablecoins are natively used for gas and settlement. It offers gasless USDT0 transfers, high-volume USDT transactions, and efficient USDT issuance/settlement. Stable operates with sub-second block finality, high transaction capacity (thousands of TPS), and Ethereum Virtual Machine (EVM) compatibility.

The StableBFT consensus protocol initially uses a CometBFT-based Proof-of-Stake (PoS) mechanism and plans to transition to a DAG-based Autobahn consensus in the future. Features like Stable Wallet and Stable Name provide a user-friendly experience, simplifying onboarding with social login and human-readable addresses. Stable is an optimized, USDT-focused blockchain infrastructure for both individual users and enterprises.

Purpose of Stable

As digital finance accelerates, stablecoins like USDT are becoming central to on-chain activities. However, existing blockchain infrastructures are not optimized for stablecoin-based operations, leading to issues such as high fees, unpredictable costs, complex user experiences, and enterprise limitations. Stable addresses these challenges by providing a USDT-specific blockchain. It meets demands for low costs, high speed, and reliability, offering gasless transfers for individual users, guaranteed blockspace for enterprises, and EVM-compatible tools for developers. Targeting USDT’s $150 billion market cap and over 350 million users, Stable aims to mainstream stablecoin usage in cross-border payments, daily transactions, and financial services. Stable enhances financial inclusion and expands the real-world applications of stablecoins by enabling global-scale USDT movement.

How Does It Work?

Stable is a Layer 1 blockchain optimized for USDT transactions. Its technical infrastructure consists of the following components:

• StableBFT: Initially, a customized CometBFT-based PoS consensus provides high throughput, low latency, and tolerance to 1/3 validator failures. In the future, a transition to Autobahn (PBFT-on-DAG) consensus aims for 5x faster consensus and 200,000+ TPS.

• Stable EVM: An Ethereum-compatible execution layer that works with tools like MetaMask and Etherscan. Precompiles bridging with StableSDK allow smart contracts to securely access core chain logic.

• StableDB: Addresses disk I/O bottlenecks by separating state commitment and storage with MemDB and VersionDB, offering fast memory-based access via mmap.

• High-Performance RPC: Replaces monolithic RPC with lightweight nodes separating read/write operations, targeting 10,000+ RPS and <100ms latency.

• USDT0: Compliant with LayerZero’s Omnichain Fungible Token (OFT) standard, enabling bridge-less cross-chain USDT transfers. Locked/burned on the source chain and minted on the destination.

• gasUSDT: Native gas token, automatically converted from USDT0, allowing users to hold only USDT0 (via Account Abstraction).

• Stable Wallet & Stable Name: Simplifies user experience with social login, mobile/web access, and human-readable addresses.

Transaction Flow:

• USDT0 Transfer: User initiates a gasless USDT0 transfer via Stable Wallet → Signs with EIP-7702 account → Bundler submits to the network → Transfer completes without gas fees.

• Smart Contract Interaction: User pays gas with USDT0 → Bundler and paymaster convert USDT0 to gasUSDT → Contract executes.

Future Plans:

• Optimistic Parallel Execution (OPE): Block-STM enables parallel execution, detecting and re-executing conflicts, providing 2x throughput gains.

• StableVM++: C++-based EVMONE for 6x execution speed.

• USDT Transfer Aggregator: Processes USDT0 transfers in batches, increasing throughput.

• Guaranteed Blockspace: Reserved blockspace for enterprises, ensuring fixed latency and costs.

• Confidential Transfer: Uses ZK cryptography to hide transfer amounts while ensuring regulatory compliance.

Stable Use Cases

Stable is used in the following areas:

• Cross-Border Payments: Gasless USDT0 transfers for low-cost, fast international payments.

• Treasury Operations: Predictable costs and guaranteed blockspace for enterprise payments/settlements.

• DeFi: Gasless, high-throughput DeFi transactions with USDT0.

• Consumer Payments: USDT-linked cards for daily spending.

• Merchant Payment Terminals: Intermediary-free, low-cost USDT acceptance.

• Financial Inclusion: USDT-based financial services in regions with limited banking access.

Usage Steps:

1. Connect to Stable Wallet via social login or MetaMask.

2. Bridge USDT0 to Stable via LayerZero.

3. Perform gasless USDT0 transfers or pay gas with USDT0 for DeFi/NFT transactions.

4. Manage addresses easily with Stable Name.

5. Spend using card integrations.

Advantages of Stable

• High Throughput: Thousands of TPS, sub-second finality.

• Gasless USDT0 Transfer: Zero fees via EIP-7702 and Account Abstraction.

• EVM Compatibility: Seamless development with Ethereum tools.

• Enterprise Features: Guaranteed blockspace, confidential transfers, regulatory compliance.

• User-Friendly: Stable Wallet, Stable Name, social login.

• Cross-Chain: Bridge-less, low-slippage USDT0 transfers.

• Security: StableBFT, ZK cryptography, OFAC compliance.

Stable Tokenomics

Project uses USDT0 and gasUSDT instead of a native token:

• USDT0: ERC-20 token compliant with OFT standard for cross-chain transfers. Bridged to Stable from chains like Ethereum, Arbitrum, and Tron.

• gasUSDT: Gas token, automatically converted from USDT0, with restricted transfers (aligned with OFAC sanctions).

• Distribution: USDT0 leverages existing USDT liquidity, providing deep liquidity from day one.

• Economy: Gasless USDT0 transfers and low-fee smart contract interactions. Guaranteed blockspace offers fixed costs for enterprises.

Stable Investors

Raised $28 million:

• Tier 2: Hack VC, Mirana Ventures, Nascent, KuCoin Ventures, eGirl Capital.

• Tier 3: Castle Island Ventures, Franklin Templeton Investments, PayPal Ventures, Bybit, Blue Pool Capital.

• Tier 4: BTSE, Bitfinex, Susquehanna International Group.

• Individual: Nathan McCauley, Paolo Ardoino, Gabriel Abed, Bryan Johnson.

Technical Infrastructure of Stable

• StableBFT: CometBFT-based PoS, with future Autobahn (DAG) for 200,000+ TPS.

• Stable EVM: EVM-compatible with StableSDK precompiles, StableVM++ for 6x speed.

• StableDB: MemDB, VersionDB, mmap for disk I/O optimization.

• RPC: Lightweight, function-based nodes; 10,000+ RPS, <100ms latency.

• USDT0: OFT standard, gasless cross-chain transfers.

• USDT Transfer Aggregator: Batch transfer processing, parallel execution.

• Confidential Transfer: ZK for hidden amounts, regulatory compliance.

Stable Roadmap

Stable will transform global payments as a USDT-specific blockchain. In Phase 1 (now), it offers gasless USDT0 transfers and EVM compatibility. In Phase 2 (Q4 2025), parallel execution and StableDB will boost throughput. In Phase 3 (Q2 2026), DAG consensus will target 10,000+ TPS. Stable will enhance financial inclusion and efficiency by enabling USDT for daily payments to enterprise settlements.

The stablecoin giant has launched XAUt0, an omnichain version of its gold-backed token XAUt, on TON (The Open Network), marking a new chapter in digital precious metals.

A New Standard in Gold Investing

Built on LayerZero’s “Omnichain Fungible Token” standard, XAUt0 enables seamless transfers across blockchains without using wrapping mechanisms or middlechains. This technical leap allows broader and more flexible access to digital gold.

XAUt, available only on Ethereum, is currently the largest gold-backed stablecoin by market cap at $832 million, closely followed by Pax Gold at $811 million. Tether backs the token with over 7.7 tons of physical gold stored in a Swiss vault, according to its Q1 2025 attestation.

The move follows Tether’s launch of USDt on the TON network earlier in 2024 and mirrors the structure of USDT0, its omnichain dollar-pegged token that spans multiple chains through Optimism’s Superchain ecosystem.

Gold Prices Surge Amid Global Uncertainty

Gold prices have surged in 2025, driven largely by economic instability and escalating trade tensions. As of May 30, gold traded at $3,304 per ounce — a 29.5% increase from the previous year.

Gold ETFs have also performed strongly, with the top eight funds gaining over 25% year-to-date. Tether’s XAUt0 is set to compete with such instruments, offering digital asset investors a new way to access gold’s stability in turbulent times.
