Management API

The APIs supported by abeychain are mainly based on function modules: admin, miner, personal, etc. These APIs are provided using JSON-RPC.

Enabling the management APIs

gabey comes with a JavaScript console that supports all of the APIs described here. To provide these APIs through gabey RPC, specify them with the --${interface}api command line argument. Where ${interface} can be HTTP rpc, WebSocket ws and Unix socket ipc or Windows pipe
For example: gabey --ipcapi admin, abey,miner --rpc api abey,web3 --rpc
  1. 1.
    Enable administrators, official DApp and miner APIs via IPC interface
  2. 2.
    Enable official DApp and web3 API via HTTP interface
The HTTP RPC interface must be explicitly enabled using the --rpc flag.
Please note, offering an API over the HTTP (rpc) or WebSocket (ws) interfaces will give everyone access to the APIs who can access this interface (DApps, browser tabs, etc). Be careful which APIs you enable. By default gabey enables all APIs over the IPC (ipc) interface and only the db, abey, net and web3 APIs over the HTTP and WebSocket interfaces.
To determine which APIs an interface provides, the modules JSON-RPC method can be invoked. For example over an ipc interface on unix systems:
echo '{"jsonrpc":"2.0","method":"rpc_modules","params":[],"id":1}' | nc -U $datadir/gabey.ipc
will give all enabled modules including the version number:
{
"id":1,
"jsonrpc":"2.0",
"result":{
"admin":"1.0",
"debug":"1.0",
"abey":"1.0",
"miner":"1.0",
"net":"1.0",
"personal":"1.0",
"rpc":"1.0",
"txpool":"1.0",
"web3":"1.0"
}
}

Admin

The admin API gives you access to several non-standard RPC methods, which will allow you to have a fine grained control over your gabey instance, including but not limited to network peer and RPC endpoint management.

admin_addPeer

The addPeer administrative method requests adding a new remote node to the list of tracked static nodes. The node will try to maintain connectivity to these nodes at all times, reconnecting every once in a while if the remote connection goes down.
The method accepts a single argument, the enode URL of the remote peer to start tracking and returns a BOOL indicating whether the peer was accepted for tracking or some error occurred.
Client
Method invocation
Go
admin.AddPeer(url string) (bool, error)
Console
admin.addPeer(url)
RPC
{"method": "admin_addPeer", "params": [url]}

Example

> admin.addPeer("enode://0adc97d2046e0b96956feed699b92fc34d2e5ba1f7ab411c884786ded213f70c0[email protected]192.168.46.59:30313")
true

admin_datadir

The datadir administrative property can be queried for the absolute path the running gabey node currently uses to store all its databases.
Client
Method invocation
Go
admin.Datadir() (string, error)
Console
admin.datadir
RPC
{"method": "admin_datadir"}

Example

> admin.datadir
"/home/abeychain/go-abey/cmd/gabey/data"

admin_nodeInfo

The nodeInfo administrative property can be queried for all the information known about the running gabey node at the networking granularity. These include general information about the node itself as a participant of the P2P overlay protocol, as well as specialized information added by each of the running application protocols (e.g. abey, les, shh).
Client
Method invocation
Go
admin.NodeInfo() (*p2p.NodeInfo, error)
Console
admin.nodeInfo
RPC
{"method": "admin_nodeInfo"}

Example

> admin.nodeInfo
{
enode: "enode://44826a5d6a55f88a18298bca4773fca5749cdc3a5c9f308aa7d810e9b31123f3e[email protected][::]:30303",

{"method": "personal_newAccount", "params": [string]}

Example

> personal.newAccount()
Passphrase:
Repeat passphrase:

personal_unlockAccount

Decrypts the key with the given address from the key store.
Both passphrase and unlock duration are optional when using the JavaScript console. If the passphrase is not supplied as an argument, the console will prompt for the passphrase interactively.
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 gabey exits.
The account can be used with abey_sign and abey_sendTransaction while it is unlocked.
Client
Method invocation
Console

RPC
{"method": "personal_unlockAccount", "params": [string, string, number]}

Examples

If you want to type in the passphrase and stil override the default unlock duration, pass null as the passphrase.

personal_sendTransaction

Validate the given passphrase and submit transaction.
The transaction is the same argument as for abey_sendTransaction and contains the fromaddress. If the passphrase can be used to decrypt the private key belogging 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.
Client
Method invocation
Console
personal.sendTransaction(tx, passphrase)
RPC
{"method": "personal_sendTransaction", "params": [tx, string]}

Examples

> var tx = {from: "0x391694e7e0b0cce554cb130d723a9d27458f9298", to: "0xafa3f8684e54059998bc3a7b0d2b0da075154d66", value: web3.toWei(1.23, "abey")}
undefined
> personal.sendTransaction(tx, "passphrase")
0x8474441674cdd47b35b875fd1a530b800b51a5264b9975fb21129eeb8c18582f

personal_sign

The sign method calculates an abeychain specific signature with:sign(keccack256("\x19abeychain Signed Message:\n" + len(message) + message))).
By adding a prefix to the message makes the calculated signature recognisable as an abeychain specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
See ecRecover to verify the signature.
Client
Method invocation
Console
personal.sign(message, account, [password])
RPC
{"method": "personal_sign", "params": [message, account, password]}
