Gasless Transaction
Quick Answer
A gasless transaction is one where the end user pays no gas fee — a third party like SpacePay sponsors the cost using meta-transactions or account abstraction.
Full Definition
A gasless transaction is a blockchain transaction where the end user does not pay the gas fee directly. Instead, a third party (such as a payment provider or dApp) sponsors the gas cost using meta-transactions or account abstraction. The user signs the transaction, and a relayer submits it on-chain and pays the gas. Gasless transactions are essential for mainstream crypto payment adoption because they remove the requirement for customers to hold ETH, MATIC, or other native gas tokens just to make a purchase.

Gas Fee
A gas fee is the cost paid to validators for processing a blockchain transaction. SpacePay covers gas fees for customers, removing the need to hold native tokens.
