Stable

Stable (STABLE) is the native coordination token of StableChain, a Layer 1 blockchain built for stablecoin payments and settlements with Tether’s USDT as the native gas and settlement asset. StableChain is EVM compatible, targets sub-second finality and aims for high throughput, while users only need to hold and spend USDT for fees and transfers.

STABLE does not function as a payment coin or gas token. It is a fixed-supply governance and security asset used for staking, validator selection, protocol governance and ecosystem incentives, while the user-facing experience remains USDT-only.

STABLE is distinct from generic “stablecoins” and other tokens that may use a similar ticker. Here STABLE refers to the governance and staking token of the StableChain network.

StableChain uses a Delegated Proof-of-Stake consensus protocol often referred to as StableBFT.

• Validators must stake STABLE as collateral to join consensus and produce blocks
• Token holders can delegate STABLE to validators to participate without running their own infrastructure
• Misbehavior such as double-signing or extended downtime can lead to slashing of staked STABLE

Stakers and delegators help secure the network and may receive a share of protocol fee revenue, although users continue to pay all on-chain fees in USDT.

STABLE is the governance token for the Stable ecosystem. Holders who stake or delegate their tokens can participate in decisions that can include:

• Approving protocol upgrades
• Adjusting network parameters
• Allocating ecosystem and community reserves
• Shaping validator and governance frameworks

Governance rights are planned to roll out in phases as StableChain and its ecosystem expand.

In StableChain’s design:

• All transaction fees are paid in USDT
• These USDT fees accumulate in protocol-controlled treasuries or vaults
• Validators can choose to share a portion of this USDT with their STABLE delegators

This structure leads to:

• Users only needing USDT for normal transfers and dapp activity
• STABLE being required for staking, governance and potential fee-sharing rights
• Demand for STABLE being linked to the scale of USDT settlement and activity on StableChain

A significant share of STABLE is reserved for ecosystem and community programs, such as:

• Developer grants and infrastructure support
• Liquidity and integration programs
• User acquisition and stablecoin payment corridors
• Strategic partnerships and validator onboarding initiatives

These rewards come from predefined STABLE reserves, aligning incentives for builders, validators and users who grow network activity.

Stable documentation describes STABLE as a fixed-supply token with 100 billion units. The protocol does not rely on ongoing inflation; incentives are funded from allocated reserves.

At mainnet and token generation, a minority portion of the supply is released for initial distribution and liquidity. The remaining tokens are subject to vesting schedules, ecosystem programs and treasury management. Circulating supply is expected to grow over time as locked allocations vest and ecosystem programs distribute tokens.

Public tokenomics outline four main allocation groups:

• Genesis distribution – 10% (10 billion STABLE) Used for initial liquidity, community activation and early partner campaigns

• Ecosystem and community – 40% (40 billion STABLE) Supports developer grants, integrations, partnerships and broader ecosystem growth

• Team – 25% (25 billion STABLE) Reserved for founders, engineers, researchers and contributors to align incentives with long-term network health

• Investors and advisors – 25% (25 billion STABLE) Allocated to strategic backers and advisors who support development and adoption

Team and investor allocations follow structured vesting, typically:

• A cliff period from token generation during which no tokens unlock
• Linear vesting over several years after the cliff
• A total vesting horizon of multiple years from the token generation event

Genesis and some ecosystem allocations can have more flexible release patterns. The overall design aims to support long-term alignment and reduce short-term supply pressure.

StableChain separates user-facing settlement from protocol coordination:

• USDT is used for all gas fees and payments
• STABLE is not required for everyday transfers or dapp interactions
• STABLE is used for staking, governance and access to fee-sharing rights

This model keeps user costs and balances denominated in a single stable asset while reserving STABLE for network-level coordination.

From a developer perspective, StableChain provides:

• Sub-second deterministic finality via its BFT-style consensus
• High throughput suited for payment flows and batch operations
• Full EVM compatibility so existing Solidity contracts and Ethereum tooling can be reused
• An environment optimized around USDT as the native asset

STABLE is the asset staked within this environment, so its utility and demand track the growth of USDT-based settlement and applications on StableChain.

Stable and the STABLE token are developed by Stable, the company behind StableChain, together with the Stable Foundation, which is being formed to oversee governance and ecosystem reserves over time. The project is closely associated with Tether and Bitfinex, which led Stable’s seed funding and act as strategic partners.

• Joshua Harding as the founder of Stable and early chief executive, credited with the concept of a USDT-native blockchain focused on payments
• Brian Mehler as the current CEO of Stable, with a background in traditional finance and prior work on large ecosystem funds in the digital asset space

Stable’s seed round was led by Bitfinex and Hack VC with participation from other institutional investors. Together, the Stable team, Stable Foundation, Tether and its backers designed StableChain’s USDT-native architecture and the STABLE token’s role in staking, governance and long-term ecosystem incentives.
