eth_getBalance
Returns the account balance for a given account address and Block Number.
The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).
By adding a prefix to the message makes the calculated signature recognizable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
Creates new message call transaction or a contract creation for signed transactions. You can get signed transaction data using the personal_sign method.
Parameters
The signed transaction data
//Requestcurl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendRawTransaction","params":["0xf9ff74c86aefeb5f6019d77280bbb44fb695b4d45cfe97e6eed7acd62905f4a85034d5c68ed25a2e7a8eeb9baf1b8401e4f865d92ec48c1763bf649e354d900b1c"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

eth_call
Executes a new message call immediately without creating a transaction on the block chain.
Parameters
Object containing:
from: DATA, 20 Bytes - (optional) The address the transaction is sent from.
to: DATA, 20 Bytes - The address the transaction is directed to.
gas: QUANTITY - gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
gasPrice: QUANTITY - gasPrice used for each paid gas
value: QUANTITY - value sent with this transaction
data: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation
Returns the receipt of a transaction by transaction hash.

eth_getLogs
Returns an array of all logs matching a given filter object.
Parameters
Object containing:
fromBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
toBlock: QUANTITY|TAG - (optional, default: "latest") Integer block number, or "latest" for the last mined block or "pending", "earliest" for not yet mined transactions.
address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.
topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with “or” options.
blockhash: (optional, future) With the addition of EIP-234, blockHash will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in in the filter criteria, then neither fromBlock nor toBlock are allowed.
subscribe using JSON-RPC notifications. This allows clients to wait for events instead of polling for them.
It works by subscribing to particular events. The node will return a subscription id. For each event that matches the subscription a notification with relevant data is send together with the subscription id.
Imports the given unencrypted private key (hex encoded string) into the key store, encrypting it with the passphrase.
Returns the address of the new account.

personal_unlockAccount
Private: Requires authentication.
Decrypts the key with the given address from the key store.
Both passphrase and unlock duration are optional when using the JavaScript console. The unencrypted key will be held in memory until the unlock duration expires. If the unlock duration defaults to 300 seconds. An explicit duration of zero seconds unlocks the key until geth exits.
The account can be used with eth_sign and eth_sendTransaction while it is unlocked.
Validate the given passphrase and submit transaction.
The transaction is the same argument as for eth_sendTransaction and contains the from address. If the passphrase can be used to decrypt the private key belonging to tx.from the transaction is verified, signed and send onto the network.
The account is not unlocked globally in the node and cannot be used in other RPC calls.
Parameters
Object containing:
from: DATA, 20 Bytes - The address the transaction is send from.
to: DATA, 20 Bytes - (optional when creating new contract) The address the transaction is directed to.
value: QUANTITY - value sent with this transaction
The traceTransaction debugging method will attempt to run the transaction in the exact same manner as it was executed on the network. It will replay any transaction that may have been executed prior to this one before it will finally attempt to execute the transaction that corresponds to the given hash.
Get the hashrate in H/s (Hash operations per second).
Proof-of-Work specific. This endpoint always returns 0.
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":[],"id":1}' -H "Content-Type: application/json" http://localhost:8545
// Result
{"jsonrpc":"2.0","id":1,"result":0}
miner_setExtra
Private: Requires authentication.
Sets the extra data a validator can include when proposing blocks. This is capped at 32 bytes.
Unsupported. This endpoint always returns an error
Parameters
Data
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setExtra","params":["data"],"id":1}' -H "Content-Type: application/json" http://localhost:8545
// Result
{"jsonrpc":"2.0","id":1,"result":false}
miner_setGasPrice
Private: Requires authentication.
Sets the minimal gas price used to accept transactions. Any transaction below this limit is excluded from the validator block proposal process.
This method requires a node restart after being called because it changes the configuration file.
Make sure your blockxd start call is not using the flag minimum-gas-prices because this value will be used instead of the one set on the configuration file.
Parameters
Hex Gas Price
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_setGasPrice","params":["0x0"],"id":1}' -H "Content-Type: application/json" http://localhost:8545

Hex Number of threads
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"miner_start","params":["0x1"],"id":1}' -H "Content-Type: application/json" http://localhost:8545
// Result
{"jsonrpc":"2.0","id":1,"result":false}
miner_stop
Private: Requires authentication.
Stop the validation operation.
Unsupported. This endpoint always performs a no-op.
Sets the gas limit the miner will target when mining. Note: on networks where EIP-1559 is activated, this should be set to twice what you want the gas target (i.e. the effective gas used on average per block) to be.
Unsupported. This endpoint always returns false
Parameters
