eth_syncing

Returns an object with data about the sync status or false. Parameters None Returns The precise return data varies between client implementations. All clients return False when the node is not syncing, and all clients return the following fields:
  • Object: [Boolean], An object with sync status data or FALSE, when not syncing.

​
eth_getStorageAt

Returns the value from a storage position at a given address. Parameters
  • DATA, 20 Bytes - address of the storage.
  • QUANTITY - integer of the position in the storage.
  • QUANTITY|TAG - integer block number, or the string “latest”, “earliest”, “pending”, “safe”, “finalized”, see the default block parameter

// Response
Either the returns the representation of the smart contract or if no smart contract found:
{"jsonrpc": "2.0", "id": 1, "result": "0x"}

​
eth_sign

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 it makes the calculated signature recognizable as an Ethereum specific signature. This prevents misuse where a malicious dApp can sign arbitrary data (e.g. transactions) and use the signature to impersonate the victim. Note: the address to sign with must be unlocked. Parameters
  • DATA, 20 Bytes - address
  • DATA, N Bytes - message to sign
Returns DATA: Signature Example 
// Request
curl -X POST https://testnet-rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_sign","params":["0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "0xdeadbeaf"],"id":1}'
// Result
{"id":1, "jsonrpc": "2.0", "result": "0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"}

​
eth_call

Executes a new message call immediately without creating a transaction on the blockchain. Often used for executing read-only smart contract functions, for example the balanceOf for an ERC-20 contract. Parameters
  • Object - The transaction call object
  • 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 - (optional) Integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
  • gasPrice: QUANTITY - (optional) Integer of the gasPrice used for each paid gas
  • value: QUANTITY - (optional) Integer of the value sent with this transaction
  • input: DATA - (optional) Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI in the Solidity documentation.
  • QUANTITY|TAG - integer block number, or the string “latest”, “earliest”, “pending”, “safe” or “finalized”, see the default block parameter
Returns DATA - the return value of executed contract. Example 
// Request
curl -X POST https://testnet-rpc1.autheo.com -H "Content-Type: application/json" --data '{"jsonrpc": "2.0", "method": "eth_call", "params": [{"to": "0x89A7EF2F08B1c018D5Cc88836249b84Dd5392905", "data": "0x18160ddd"}, "latest"], "id": 1}'
// Result
{
  "id":1,
  "jsonrpc": "2.0",
