eth_maxPriorityFeePerGas JSON-RPC reference for MegaETH.
Last updated
eth_maxPriorityFeePerGas JSON-RPC reference for MegaETH.
Returns the recommended priority fee per gas in wei. MegaETH returns a zero-wei priority fee because priority fees are not needed under the current fee policy.
The public MegaETH endpoint supports this method. The standard, node, and gateway layers below identify behavior that differs from a generic Ethereum endpoint.
None.
result Quantity
Always a zero-wei quantity.
The canonical Ethereum method uses the parameter and result contract documented above, including the stated null, false, or zero-value semantics where applicable.
The node fee policy does not require a priority fee, but the public result is synthesized by the gateway rather than used as evidence of a node query.
The gateway synthesizes a zero-wei priority fee without calling a node. This is a current MegaETH fee-policy response, not a market estimate.
The | Scope | column distinguishes method failures from gateway policy errors.
No method-specific errors were observed.

Transport/policy
Rate limit exceeded
The caller exceeds the public gateway's simple read budget.
