Live on Base Sepolia

One coin.
Every chain.

Hold STTR on Base and spend it on any EVM chain — or pay in with whatever you already hold elsewhere. One balance. All the liquidity in one place.

The problem

There is no standard. There are forty of them.

Every network charges fees in its own asset. To act on Ethereum you need ETH. On Solana, SOL. On Polygon, POL. A payment standard that only works in one place is not a standard — it is a walled garden with a token attached.

Stuck value

You can't spend what you hold

A stablecoin on a chain where you hold no native token is stuck. You own value you cannot move, and moving it costs an asset you do not have.

Transfer blocked: this wallet has no ETH to pay the network
Repeated friction

Every new chain starts over

Acquire the native token first — from an exchange, or a bridge that itself needs gas — before the first transaction. Each chain repeats the whole loop.

Fixed costs

Small balances become unusable

Gas is a fixed cost, not a percentage. A wallet holding a few dollars across three chains may not be able to afford to consolidate them at all.

With Stater

One balance that pays everywhere

Hold STTR and nothing else. The network fee is settled in STTR on whichever supported chain you act on, so there is no second asset to find first.

How it works

You hold one asset. The rail does the rest.

The user never touches a native gas token. They sign the action they actually wanted; a paymaster settles the network fee and is compensated in STTR.

01

You sign

Holding only STTR. No native token on the destination chain, no bridging first.

sign(order, permit) · no gas
02

A paymaster settles

It pays the network in the native asset and takes STTR in return.

pays gas · takes STTR
03

The chain sees a paid transaction

Ordinary and fully funded. Your balance stays in one place.

status success · paid in full
Already running

On Base Sepolia today. A wallet holding no ETH signs a sale; a relayer pays the gas and is paid back in STTR out of the sale. The contract checks everything the holder signed, so the relayer can submit the order but never change it.

One token, not copies

STTR itself moves between chains natively through ERC-7802 burn-and-mint, rather than as wrapped copies — so there is one STTR, not a family of bridged representations that drift apart.

How universal gas works

What we are building

Three products. One asset.

Each gives a reason to hold STTR that does not depend on the other two.

Universal gas

Transact anywhere, holding one asset

The primary demand driver: using the network consumes STTR.

How it works
Social finance

Money that moves between people

Payments, balances and settlement between people, denominated in STTR. The consumer surface for the same rail.

What it does
DAO governance

One token, one vote — and the vote has to be real

Measured by checkpoints, so a balance borrowed for a single transaction carries no weight. Holders steer the protocol, including which bridges may move supply.

of supply — 2,000,000,000 STTR. The single largest allocation, and bigger than the team and early investor combined by a wide margin.

Goes to the people who use it.

Aimed at power users of EVM chains, weighted toward Base.

On-chain history

Genuine sustained activity across EVM chains, weighted toward Base. Not one-off volume, not a wallet made for a snapshot.

Testing our products

Using the testnet deployments and stressing the gas-abstraction flow before it carries real value.

Social participation

Contribution to the community rather than follower counts — answering, translating, writing, moderating.

More criteria

Published in full before the snapshot, so nobody is scored against rules they could not read in advance.

You will have to earn it. Scoring across several independent signals is what makes farming expensive — a wallet optimised for one metric scores poorly on the rest. Read the full criteria

Why it is credible

What the code prevents, not what we promise.

Anyone can write a good intention into a document. These are enforced by contracts you can read, and none of them depends on our continued good behaviour.

Supply cannot be inflated

mint()

There is no mint function. Not for an owner, not for an admin, not for us. 10,000,000,000 STTR, once.

No wallet can be frozen

freeze()blacklist()pause()

No blacklist, no freeze, no pause, no transfer limit. The transfer path contains no condition any privileged account controls.

No fee can be switched on

setFee()setTax()

There is no fee mechanism in the contract to enable later. Zero is not a setting; it is the absence of the machinery.

Vested tokens cannot be clawed back

revoke()clawback()

Once sealed, nothing returns the vested token to anyone but its beneficiary — not even a unanimous multisig.

Where we actually are

Pre-launch, and saying so.

The contracts are written, tested and running on Base Sepolia. They are not on mainnet, they have not been audited, and STTR is not tradeable. We would rather you read that here than discover it later.

The testnet app runs against the real contracts: claim 1 free STTR a day or buy more with Base Sepolia ETH, sell it with no ETH at all, or sell it for real SOL on Solana devnet.
