JSON RPC API

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

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 () as data format.

go-symverse supports JSON-RPC 2.0

JavaScript API

To talk to an symverse node from inside a JavaScript application offering API library with the library (from Ethereum)

the library gives an convenient interface for the RPC methods. See the for more.

JSON-RPC Endpoint

Default JSON-RPC endpoints:

  http://localhost:8545

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

  > gsym --rpc

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

  > gsym --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:

  > gsym --rpc --rpccorsdomain "http://localhost:3000"

The JSON RPC can also be started from the gsym console using the admin.startRPC(addr, port) command.

Output HEX values

At present there are two key datatypes that are passed over JSON: unformatted byte arrays and quantities. Both are passed with a hex encoding, however with different requirements to formatting:

When encoding QUANTITIES (integers, numbers): encode as hex, prefix with "0x", the most compact representation (slight exception: zero should be represented as "0x0"). Examples:

0x41 (65 in decimal)
0x400 (1024 in decimal)
WRONG: 0x (should always have at least one digit - zero is "0x0")
WRONG: 0x0400 (no leading zeroes allowed)
WRONG: ff (must be prefixed 0x)

When encoding UNFORMATTED DATA (byte arrays, account addresses, hashes, bytecode arrays): encode as hex, prefix with "0x", two hex digits per byte. Examples:

0x41 (size 1, "A")
0x004200 (size 3, "\0B\0")
0x (size 0, "")
WRONG: 0xf0f0f (must be even number of digits)
WRONG: 004200 (must be prefixed 0x)

Currently go-symverse provides JSON-RPC communication only over http.

The default block parameter

Some methods have a extra default block parameter.

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

sym_sign

The sign method calculates an Symverse specific signature with: sign(sha256("\x19Symverse Signed Message:\n" + len(message) + message))).

Note the address to sign with must be unlocked.

DATA, N Bytes - message to sign.

Returns

DATA: Signature

sym_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 sym_call parameters, expect that all properties are optional. If no gas limit is specified gsym 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

// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"sym_estimateGas","params":[{see above}],"id":1}'
