What Are Gasless Transactions?
A gasless transaction is a blockchain transaction where the user does not pay the network fee from their own balance. Instead, a third party — usually a smart contract called a paymaster, or a relayer service — sponsors the fee or accepts payment in a different token, such as a stablecoin.
"Gasless" doesn't mean the network works for free: someone always pays the fee. The point is who pays, and in what currency. Sponsored fees solve the classic cold-start problem where a new user holds tokens but can't move them because they lack the chain's native coin for gas.
How Gasless Transactions Work
You sign the action you want — a transfer, swap, or mint — but not the fee payment.
A paymaster contract or relayer attaches the gas payment and submits the transaction to the network.
The sponsor either absorbs the cost (as a promotion or app expense) or charges you in another token you actually hold.
The network processes it like any other transaction — fees are paid, just not directly by you in the native coin.
What to Watch For
Nothing is free forever: understand how the sponsor recoups the cost — a markup, a spread, or a marketing budget.
The signature still rules: a sponsored transaction can still contain a harmful approval; read it like any other.
Availability varies: gasless flows depend on the chain, the app, and the token involved.
Gasless Transactions and Trust Wallet
Trust Wallet is a self-custody wallet, so whether a fee is sponsored or paid from your balance, nothing moves without your signature. The Security Scanner reviews transactions before you approve them — sponsored gas changes who pays the fee, not how carefully you should sign.
