Sponsor fees & rent on Solana

Fees and rent are a significant barrier to entry for new users of your app. Sponsor fees and rent to enable users to transact without holding SOL.

• Works with any Solana wallet. Check out Solana Smart Wallets
• No need to manage SOL, we sponsor fees & rent and put it on your bill

How it works

When you request gas sponsorship for a transaction using a configured policy, the policy engine will determine if that transaction is eligible for sponsorship. If eligible, Gas Manager will pay for the fees and rent upfront when the user sends the transaction. Gas Manager will make a note of the sponsored cost and add it to your monthly bill.

• Fees: the cost of executing transactions
• Rent: the minimum payment to store data onchain
  • Rent sponsorship is supported for createAccount and createAssociatedTokenAccount. If you need support for custom programs, contact [email protected].

Prerequisites

• API key from your dashboard
• Smart Wallets for Solana set up in your project if you want to enable sign up/login for creation of wallets
• A sponsorship policy to cover fees and/or rent: create a policy
