--- title: Fee Sponsorship description: Learn about Solana's fee sponsorship, including how to sponsor fees for other users and how to get paid for sponsoring fees. --- ## Overview Fee sponsorship is a native feature in Solana that allows for one account to pay transaction fees for another account. This is useful if you want to abstract away holding SOL from your users or provide a fee-free experience. This is also often referred to as "gas abstraction" on other blockchains. ## How fee payment works Every transaction requires a transaction fee, paid in SOL. This fee is paid by the "fee payer" of the transaction. Any EOA that signs the transaction can be the fee payer which enables native fee sponsorship or "gas abstraction" for Solana. This capability extends to all transaction types including token transfers, DeFi actions, and more. For more information on how fees are determined see the [Transaction Fees](/docs/core/fees) page. ## How to sponsor fees on a transaction To sponsor fees for other users, you need to create a transaction with the `feePayer` field set to the public key of the EOA that will pay the fees. The following example shows how to transfer a token from one user to another and sponsor the fees for the transaction. ```ts !! title="Kit" file=packages/docs-examples/cookbook/transactions/fee-sponsorship/kit.ts#region=sponsor ``` ```ts !! title="Legacy" file=packages/docs-examples/cookbook/transactions/fee-sponsorship/legacy.ts#region=sponsor ``` ```ts !! title="Legacy Helper" file=packages/docs-examples/cookbook/transactions/fee-sponsorship/legacy-helper.ts#region=sponsor ``` ## How to run a fee relayer service A fee relayer service is a service that allows you to relay transactions for other users. This is useful if you want to provide an application that removes the complexity of users having to manage and procure SOL. Kora, by the Solana Foundation, is a fee relayer service that allows you to relay transactions for other users. In addition to providing fee sponsorship, it can also accept fee payment in configured tokens to still be compensated for transaction processing. More information can be found in the [Kora documentation](/docs/tools/kora).
