JSON-RPC API

Neo X is in sync with most Ethereum JSON-RPC methods, but there are some differences to note:

• eth_chainId — returns the chain ID of Neo X.

• eth_hashrate — returns 0x0 by default.

• eth_coinbase — returns the GovReward contract address.

• eth_gasPrice — returns the maximum value of the current network GAS price and the lowest allowed GAS price by Neo X Policy.

• eth_maxPriorityFeePerGas — returns an estimated value of priority fee to get a transaction allowed by Neo X Policy and in the current block.

• eth_getUncleByBlockHashAndIndex — returns null by default.

• eth_getUncleByBlockNumberAndIndex — returns null by default.

• eth_getUncleCountByBlockHash — returns 0 by default.

• eth_getUncleCountByBlockNumber — returns 0 by default.

• eth_getCachedTransaction - returns the cached and signed secret transactions. It requires a valid sender signature in parameters, and only works on nodes configured with --txpool.amevcache;

• eth_envelopeFee - returns the minimum additional gastip/gasprice that anti-mev transactions should pay for the service.

• eth_maxEnvelopeGasLimit - returns the maximum gaslimit that an Envelope can declare for itself.
