Engine FAQs

Pricing is calculated through the number of write requests (ex: /v1/write/contract) and sign requests (ex: /v1/sign/transaction) made through the Engine API. For requests costs, see the thirdweb pricing page. Read requests made through Engine API are free, within the RPC limits/plan.

For transactions through server wallets paid through the user's thirdweb account, users will pay a 5% premium on the gas fee of each transaction completed on any mainnet as part of account abstraction fees. There are no gas charges for testnets.

Please note: Legacy pricing plans may be subject to the 10% fee specified when signed up instead of 5%. See pricing page for updated plans and benefits

The breakdown for usage and transaction fees can be found in your usage dashboard under the team overview.

While in beta, Engine Cloud currently supports every non ZK EVM-compatible chain which includes support for Account Abstraction. See the current list of supported chains.

If your chain is not listed, please contact us to prioritize enabling support.
