JSON RPC API

JSON RPC API

JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.

JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol. Primarily this specification defines several data structures and the rules around their processing. It is transport agnostic in that the concepts can be used within the same process, over sockets, over HTTP, or in many various message passing environments. It uses JSON (RFC 4627) as data format.

Getrue has experimental pub/sub support. See this page for more information.

JavaScript API

To talk to an truechain node from inside a JavaScript application use the web3.js library, which gives a convenient interface for the RPC methods.

JSON-RPC Endpoint

Default JSON-RPC endpoints: http://localhost:8545

Go

You can start the HTTP JSON-RPC with the --rpc flag

getrue --rpc

change the default port (8545) and listing address (localhost) with:

getrue --rpc --rpcaddr <ip> --rpcport <portnumber>

If accessing the RPC from a browser, CORS will need to be enabled with the appropriate domain set. Otherwise, JavaScript calls are limit by the same-origin policy and requests will fail:

getrue --rpc --rpccorsdomain "http://localhost:3000"

JSON-RPC support

JSON-RPC 2.0/ Batch requests/ HTTP/ IPC/ WS

The default block parameter

The following methods have an extra default block parameter:

etrue_getBalance
etrue_getCode
etrue_getTransactionCount
etrue_getStorageAt
etrue_call
impawn_getAllStakingAccount
impawn_getStakingAsset
impawn_getLockedAsset
impawn_getAllCancelableAsset
impawn_getStakingAccount

When requests are made that act on the state of truechain, the last default block parameter determines the height of the block.

The following options are possible for the defaultBlock parameter:

HEX String - an integer block number
String "earliest" for the earliest/genesis block
String "latest" - for the latest mined block
String "pending" - for the pending state/transactions

Curl Examples Explained

The curl options below might return a response where the node complains about the content type, this is because the --data option sets the content type to application/x-www-form-urlencoded . If your node does complain, manually set the header by placing -H "Content-Type: application/json" at the start of the call.

The examples also do not include the URL/IP & port combination which must be the last argument given to curl e.x. 127.0.0.1:8545

etrue_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" or "pending", see the default block parameter

Returns

DATA - the value at this storage position.

Example

Calculating the correct position depends on the storage to retrieve. Consider the following contract deployed at 0x295a70b2de5e3953354a6a8344e616ed314d7251 by address 0x391694e7e0b0cce554cb130d723a9d27458f9298.

contract Storage {
uint pos0;
mapping(address => uint) pos1;
function Storage() {
pos0 = 1234;
pos1[msg.sender] = 5678;
}
}

Retrieving the value of pos0 is straight forward:

curl-XPOST--data'{"jsonrpc":"2.0", "method": "etrue_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x0", "latest"], "id": 1}' localhost:8545{"jsonrpc":"2.0","id":1,"result":"0x00000000000000000000000000000000000000000000000000000000000004d2"}

Retrieving an element of the map is harder. The position of an element in the map is calculated with:

keccack(LeftPad32(key,0),LeftPad32(mapposition,0))

This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:

keccak(decodeHex("000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298"+"0000000000000000000000000000000000000000000000000000000000000001"))

The getrue console which comes with the web3 library can be used to make the calculation:

>varkey="000000000000000000000000391694e7e0b0cce554cb130d723a9d27458f9298"+"0000000000000000000000000000000000000000000000000000000000000001"undefined>web3.sha3(key,{"encoding": "hex"})"0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9"

Now to fetch the storage:

curl-XPOST--data'{"jsonrpc":"2.0", "method": "etrue_getStorageAt", "params": ["0x295a70b2de5e3953354a6a8344e616ed314d7251", "0x6661e9d6d8b923d5bbaab1b96e1dd51ff6ea2a93520fdc9eb75d059238b8c5e9", "latest"], "id": 1}' localhost:8545{"jsonrpc":"2.0","id":1,"result":"0x000000000000000000000000000000000000000000000000000000000000162e"}

Example

etrue_sign

The sign method calculates an Truechain specific signature with: sign(keccak256("\x19Truechain Signed Message:\n" + len(message) + message))).

By adding a prefix to the message makes the calculated signature recognisable as an Truechain specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.

Note the address to sign with must be unlocked.

Parameters

account, message

DATA, 20 Bytes - address.
DATA, N Bytes - message to sign.

Returns

DATA: Signature

Example

// Requestcurl-XPOST--data'{"jsonrpc":"2.0","method":"etrue_sign","params":["0x9b2055d370f73ec7d8a03e965129118dc8f5bf83", "0xdeadbeaf"],"id":1}'// Result{"id":1,"jsonrpc": "2.0","result": "0xa3f20717a250c2b0b729b7e5becbff67fdaef7e0699da4de7ca5895b02a170a12d887fd3b17bfdce3481f10bea41f45ba9f709d39ce8325427b57afcfc994cee1b"}

An example how to use solidity ecrecover to verify the signature calculated with etrue_sign can be found here. The contract is deployed on the testnet Ropsten and Rinkeby.

value: QUANTITY - (optional) Integer of the value sent with this transaction

etrue_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Parameters

See etrue_call parameters, expect that all properties are optional. If no gas limit is specified getrue uses the block gas limit from the pending block as an upper bound. As a result the returned estimate might not be enough to executed the call/transaction when the amount of gas is higher than the pending block gas limit.

Returns

QUANTITY - the amount of gas used.

Example

// Requestcurl-XPOST--data'{"jsonrpc":"2.0","method":"etrue_estimateGas","params":[{see etrue_sendTransaction parameter}],"id":1}'// Result{"id":1,"jsonrpc": "2.0","result": "0x5208"// 21000}

Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:

[] "anything"
[A] "A in first position (and anything after)"
[null, B] "anything in first position AND B in second position (and anything after)"
[A, B] "A in first position AND B in second position (and anything after)"
[[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"

etrue_getLogs

Returns an array of all logs matching a given filter object.

Parameters

Object - The filter options:

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.
