Gasless: how zero-gas actually works

“Gasless” usually means “subsidized until the grant runs out.” On OmniCoin the money comes from somewhere else entirely, which is worth explaining, because who pays is the part that decides whether a thing like this lasts.

The flow. When you act in any OmniBazaar app, your wallet signs a typed message (EIP-712) describing the intent. That signature goes to a validator, which wraps it in a real transaction through the OmniForwarder contract, following the EIP-2771 standard, and pays the native gas itself. The target contract sees you as the sender, cryptographically. You never held the gas token, never saw a fee prompt, never signed anything you didn’t read.

Who pays, then? Validators do, and knowingly. Running an OmniCoin gateway validator earns block rewards and requires a stake; relaying user transactions is part of the job description, priced into the validator economics the way electricity is priced into mining. Protocol revenue for everyone else comes from the published fee schedule: the 0.20% DEX taker fee, the 1% marketplace fee and the 0.25% interface fee, all of which are visible on your receipt.

Why this isn’t a subsidy cliff. Gas on a subnet we operate is cheap by construction, and the fee schedule scales with usage while relay costs scale with the same usage. There is no external gas market to squeeze us; the loop is closed on our own chain.

What it changes. Onboarding stops requiring a lecture (“first, buy a small amount of a token you’ve never heard of, to pay for the right to move your own money”). A new user can receive OmniCoin, trade, list an item and shield a balance without ever acquiring gas. That, more than any slogan, is what “the user is the custodian” needs to be practical.

Signed locally, relayed by validators, settled on-chain: $0.00, printed on every receipt.
