Hi everyone,
This is a quick heads-up for all builders, wallet developers, and node operators.
Transaction Fees will be updated on Flow Mainnet next week on Monday, Dec 8th as per FLIP 351: FLIP 351: Transaction Fee Update to Enable Inflation-Neutral Tokenomics.
Fees on Testnet have already been updated (see previous announcement)
What this means for you
-
Transaction fees on mainnet will increase according to the new computation unit cost and inclusion fee defined in the FLIP.
-
Applications and wallets that send transactions may require more FLOW tokens in their payer account.
Please fund your mainnet payer accounts
If your application or wallet pays for user transactions, then to avoid any disruptions in your app or wallet during the fee update, please ensure your payer accounts have enough $FLOW.
For EVM Gateway operators
Please update your EVM Gateway node to tag: v1.4.3.
If you have enabled soft-finality on the EVM GW by adding the -experimental-soft-finality-enabled=true tag, then upgrade to docker tag to v1.4.3-experimental-sf.1
With the upcoming fee increase, the EVM Gateway COA account (the account specified via --coa-address) will pay more for the Cadence transactions it submits to Flow. This means the COA account will deplete faster than before.
- Please make sure your COA account is funded with sufficient $FLOW.
The coinbase account (the account specified via --coinbase) receives EVM Gateway fees from EVM client transactions. To ensure the coinbase account recovers the FLOW spent by the COA account, you must update the Gateway’s --gas-price parameter. This also updates the minimum gas price shown to wallets such as MetaMask.
Our recommended setting is:
--gas-price=16038000000
This value corresponds to 16.038 Gwei.

This includes the motivation, fee parameter changes, and how the proposal aligns with Flow’s long term goal of sustainable, inflation neutral economics.
