Understanding gas sponsorship

Gas sponsorship is a feature that covers your network fees on certain chains, courtesy of MetaMask.

informații

If your transaction is eligible, you won’t need to pay the gas (transaction) fee. It will be covered automatically with no additional steps required.

Currently gas sponsorship is available for certain transactions on the following networks. Each network differs in terms of eligible transactions and requirements. Keep reading for more details.

Eligible networks:

• Monad
• SEI
• Solana

Monad

To qualify for sponsored transactions on Monad, you must:

• Submit a Monad transaction (e.g. a swap, send, or dapp interaction within the Monad network).
• Have at least 10 MON remaining in your wallet after the transaction, if MON is the source token. This does not apply to ERC20 swaps or sends.

Transactions between Monad and other networks are not eligible.

SEI

To qualify for sponsored transactions on SEI, you must:

• Submit a SEI transaction (e.g. a swap, send, or dapp interaction within the SEI network).

Transactions between SEI and other networks are not eligible.

Solana

The following transactions are eligible for gas sponsorship on Solana:

• Swaps on Solana with a minimum swap size of $200 in value.
• Cross-chain swaps originating from Solana, with a minimum swap size of $200 in value.

How gas sponsorship works

Gas sponsorship relies on smart accounts (EIP-7702). If your account hasn’t been upgraded yet, it will automatically convert to a smart account when you submit your first eligible transaction on a supported network.

Currently, you cannot opt out of sponsorship. If smart accounts are manually disabled, they will automatically be re-enabled when you submit an eligible transaction.

How long will my transactions be sponsored?

Gas sponsorship is currently available on select networks but not guaranteed to continue indefinitely. Availability may change at any time.

Why isn’t my transaction sponsored?

Sponsored transactions are only available on Monad, SEI, and Solana. Your transaction may not be sponsored if:

• It isn't an eligible transaction type
• It doesn't meet all requirements (such as minimum balance)
• It exceeds 5,000,000 gas (5M gas units)
• You’re using a hardware wallet account (like Ledger or Trezor), which isn’t currently supported

If your transaction doesn’t qualify, you will need to pay the network fee as usual.
