​​Stable (STABLE)

What Stable is

Stable is a layer-1 blockchain built for stablecoin payments, in which the gas token is a dollar stablecoin rather than a volatile network asset. Its documentation describes the chain as "A payments Layer 1 where USDT0 is the native gas token — instant settlement, fully EVM-compatible, no separate gas asset to manage," and the project's site positions it as "Global Infrastructure for Instant USD₮ Payments" (source: Stable documentation and site, read September 2026).

STABLE is the governance token, and USDT0 is the gas token. Stable's mainnet reference lists chain ID 988, a gas token of USDT0 with 18 decimals, and a governance token of STABLE (source: Stable documentation, mainnet information, September 2026). Those are two different assets doing two different jobs, and conflating them is the easiest mistake to make about this chain.

How it works

Paying gas in a dollar-denominated asset removes a specific friction rather than a theoretical one. On an ordinary evm chain, a business that wants to send stablecoins must also hold the network's volatile asset, top it up, account for it and explain its price movements. Making the stablecoin itself the gas asset collapses that to a single balance. It also makes fees legible: a fee quoted in a dollar unit does not need converting to be understood.

Stable's headline properties are stated as "Sub-second finality," "Sub-cent fees," "USDT-native gas" and "EVM-equivalent" (source: Stable documentation, September 2026). The documentation describes single-slot finality, meaning a block is final when it is produced rather than after a wait, and gives a mainnet block time of approximately 0.7 seconds. Fees follow "a base-fee-only model priced in USDT0," which is a simpler arrangement than eip 1559's base fee plus priority tip: there is no separate bidding lane for inclusion.

EVM equivalence is the compatibility promise. Contracts, tooling, wallets and libraries written for Ethereum work without modification, which is what makes an erc 20 payment integration portable. Stable exposes an ordinary JSON-RPC endpoint at https://rpc.stable.xyz and a WebSocket endpoint, rate-limited to 1,000 requests per 10 seconds per IP address (source: Stable documentation, mainnet information, September 2026).

The documentation also covers on- and off-ramps, agent settlement and connection tooling as first-class sections, which tells you who the chain is built for: payment operators and automated systems moving dollars, not traders or defi users chasing yield.

Supply and tokenomics

This is where the public documentation stops. The pages read in September 2026 name STABLE as the governance token in the mainnet reference and describe no supply, no allocation, no emissions schedule, no staking mechanism and no fee-sharing arrangement. This page therefore states none of those.

That gap is more consequential than usual because of how the chain is designed. On a normal layer-1, the native asset accrues value through gas demand: more usage means more fees paid in the token. Stable deliberately breaks that link by charging fees in USDT0. Whatever economic claim STABLE has must come from somewhere else, and the documentation read does not say where.

History

The idea of paying fees in a stablecoin is not new, but building an entire layer-1 around it is a recent turn. Earlier attempts approached it as an application-layer convenience: a relayer accepts a stablecoin, pays the network's gas in its native asset, and pockets the difference. That works, and it adds a trusted intermediary to every transaction. Making the stablecoin the protocol's own gas asset removes the relayer from the path.

USDT0 as the specific gas asset is the other deliberate choice. It ties the chain's core mechanic to a particular dollar token and its issuer rather than to a basket or a neutral unit, which is a considerable simplification and a considerable dependency at the same time.

Stable's documentation structure records the intended audience as clearly as its marketing does. Sections on ramps, agent settlement and connection tooling sit alongside the technical reference, and there is no prominent DeFi or trading surface. A payments chain that means it looks like this.

Risks and what to watch

Issuer dependency is structural. A chain whose gas asset is a specific dollar stablecoin depends on that stablecoin's issuer remaining solvent, willing and able to operate. A depeg, a freeze, or a blacklisting policy applied to the gas asset is not an application-level inconvenience on this chain; it is a network-level event.

Validator and consensus details are unpublished on the pages read. Sub-second single-slot finality implies a Byzantine fault tolerant design with a known validator set, and the size, identity and permissioning of that set determine the chain's real decentralization. Those are the first things to look for as documentation expands.

An unpublished token supply is a genuine gap. Without a total supply, an allocation and a vesting schedule, a holder cannot size dilution or an upcoming unlock on a chain whose token has no fee-demand backstop.

Finally, remember what EVM equivalence does and does not carry over. Contracts port, and so do contract bugs, token approval hazards and phishing patterns. A faster, cheaper chain does not make an approval you granted any safer.

Frequently asked questions

Do you pay gas in STABLE?

No. Stable's mainnet reference lists USDT0 as the gas token with 18 decimals, and STABLE as the governance token. Fees follow a base-fee-only model priced in USDT0.

How fast is Stable?

Its documentation gives a block time of approximately 0.7 seconds with single-slot finality, meaning a block is final when produced rather than after a confirmation wait.

Is Stable EVM compatible?

Yes. The documentation describes the chain as EVM-equivalent and exposes standard JSON-RPC and WebSocket endpoints, so Ethereum contracts and tooling work without modification.

What is STABLE's total supply?

Stable's documentation does not publish one on the pages read in September 2026, and this page states none. Read it from the data on this page or from a current Stable disclosure.

Where can you buy Stable?

Availability depends on your country or US state. See where to buy Stable for the venues serving your jurisdiction, and Exchanges to compare fees and kyc requirements.
