eth_accounts

Returns a list of account addresses a client owns.

Note - This is not implemented in the dev server (using database backend)

Parameters

None

Returns

Array of data: List of 20-byte account addresses owned by the client.

Note - This method returns an empty object because the API doesn't support key management inside the client.

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_accounts",
  "params": []
}

Sample Response

{
  "id": 1,  
  "jsonrpc": "2.0",
  "result": []
}

eth_blockNumber

Returns the index corresponding to the block number of the current chain head.

Note - This returns a hardcoded value of 0x1 when using database backend

Parameters

None

Returns

result : QUANTITY - Hexadecimal integer representing the index corresponding to the block number of the current chain head.

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_blockNumber",
  "params": []
}

Sample Response

{
  "id": 1,
  "jsonrpc": "2.0",  
  "result": "0x2377"
}

eth_call

Invokes a contract function locally and does not change the state of the blockchain.

You can interact with contracts using eth_sendRawTransaction or eth_call.

Note - This returns a hard coded result 0x when using database backend

Parameters

OBJECT - Transaction call object.

QUANTITY|TAG - Integer representing a block number or one of the string tags latest, earliest, or pending, as described in Block Parameter.

Note - By default, eth_call does not fail if the sender account has an insufficient balance. This is done by setting the balance of the account to a large amount of ether. To enforce balance rules, set the strict parameter in the transaction call object to true.

Returns

result - data - Return value of the executed contract.

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_call",
  "params": [
    {
      "to": "0x69498dd54bd25aa0c886cf1f8b8ae0856d55ff13",
      "value": "0x1"
    },
    "latest"
  ]
}

Sample Response

{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x"
}

eth_chainId

Returns the chain ID.

Parameters

None

Returns

result : quantity - Chain ID, in hexadecimal.

Note - this is hard coded to 0x4c

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_chainId",
  "params": []
}

Sample Response

{
  "id": 1,
  "jsonrpc": "2.0",  
  "result": "0x4c"
}

eth_coinbase

Returns the client coinbase address. The coinbase address is the account to pay mining rewards to.

Note - This is not implemented when using database backend

Parameters

None

Returns

result : data - Coinbase address.

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_coinbase",
  "params": []
}

Sample Response

{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x5e2870e87bf1b6d2d231d4ecc808f5f642334986"
}

eth_estimateGas

Returns an estimate of the gas required for a transaction to complete. The estimation process does not use gas and the transaction is not added to the blockchain. The resulting estimate can be greater than the amount of gas the transaction ends up using, for reasons including EVM mechanics and node performance.

The eth_estimateGas call does not send a transaction. You must call eth_sendRawTransaction to execute the transaction.

Parameters

The transaction call object parameters are the same as those for eth_call except for the strict parameter. If strict is set to true, the sender account balance is checked for value transfer and transaction fees. The default for strict is false.

For eth_estimateGas, all fields are optional because setting a gas limit is irrelevant to the estimation process (unlike transactions, in which gas limits apply).

object - Transaction call object.

Returns

result : quantity - Amount of gas used.

Note - in dev server, this is hard coded to 0x0 while in staging server, this is by default set to 0x5208

Sample Request

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "eth_estimateGas",
  "params": [
    {

      "value": "0x1"
    },
    "latest"
  ]
}

Sample Response

{
  "id": 1,
  "jsonrpc": "2.0",
  "result": "0x5208"
}

eth_gasPrice

Returns a percentile gas unit price for the most recent blocks, in Wei. By default, the last 100 blocks are examined and the 50th percentile gas unit price (that is, the median value) is returned.

If there are no blocks, by default it returns the minimum amount. By default the return value is restricted to values between 1000 Wei and 500 GWei.

eth_getLogs

Returns an array of logs matching a specified filter object.

Note - This is not implemented when using database backend

Attention - Using eth_getLogs to get the logs from a large range of blocks, especially an entire chain from its genesis block, can cause the API to hang and never return a response. We recommend splitting one large query into multiple ones for better performance.

Parameters

Object - Filter options object.

Returns

array - Log objects.
