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
Enable administrators, official DApp and miner APIs via IPC interface
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:
will give all enabled modules including the version number:
API List
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]}

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
).

Example
The passphrase can also be supplied as a string.
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

The transaction is the same argument as for abey_sendTransaction
and contains the from
address. 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
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]}

inspection property can be queried to list a textual summary of all the transactions currently pending for inclusion in the next block(s), as well as the ones that are being scheduled for future execution only. This is a method specifically tailored to developers to quickly see the transactions in the pool and find any potential issues.
The result is an object with two fields pending
and queued
. Each of these fields are associative arrays, in which each entry maps an origin-address to a batch of scheduled transactions. These batches themselves are maps associating nonces with transactions summary strings.
Please note, there may be multiple transactions associated with the same account and nonce. This can happen if the user broadcast mutliple ones with varying gas allowances (or even complerely different transactions).
Client
Method invocation
Go
txpool.Inspect() (map[string]map[string]map[string][]string)
Console
txpool.inspect
RPC
{"method": "txpool_inspect"}
Example
txpool_status

debugging method will attempt to run the transaction in the exact same manner as it was executed on the network. It will replay any transaction that may have been executed prior to this one before it will finally attempt to execute the transaction that corresponds to the given hash.
In addition to the hash of the transaction you may give it a secondary optional argument, which specifies the options for this specific call. The possible options are:
disableStorage
:BOOL
. Setting this to true will disable storage capture (default = false).disableMemory
:BOOL
. Setting this to true will disable memory capture (default = false).disableStack
:BOOL
. Setting this to true will disable stack capture (default = false).tracer
:STRING
. Setting this will enable JavaScript-based transaction tracing, described below. If set, the previous four arguments will be ignored.timeout
:STRING
. Overrides the default timeout of 5 seconds for JavaScript-based tracing calls. Valid values are described here.
Client
Method invocation
Go
debug.TraceTransaction(txHash common.Hash, logger *vm.LogConfig) (*ExecutionResurt, error)
Console
debug.traceTransaction(txHash, [options])
RPC
{"method": "debug_traceTransaction", "params": [txHash, {}]}
Example
JavaScript-based tracing
Specifying the tracer
option in the second argument enables JavaScript-based tracing. In this mode, tracer
is interpreted as a JavaScript expression that is expected to evaluate to an object with (at least) two methods, named step
and result
.
step
is a function that takes two arguments, log and db, and is called for each step of the EVM, or when an error occurs, as the specified transaction is traced.
log
has the following fields:
pc
: Number, the current program counterop
: Object, an OpCode object representing the current opcodegas
: Number, the amount of gas remaininggasPrice
: Number, the cost in wei of each unit of gasmemory
: Object, a structure representing the contract's memory spacestack
: array[big.Int], the EVM execution stackdepth
: The execution depthaccount
: The address of the account executing the current operationerr
: If an error occured, information about the error
If err
is non-null, all other fields should be ignored.
For efficiency, the same log
object is reused on each execution step, updated with current values; make sure to copy values you want to preserve beyond the current call. For instance, this step function will not work:
But this step function will:
log.op
has the following methods:
isPush()
- returns true if the opcode is a PUSHntoString()
- returns the string representation of the opcodetoNumber()
- returns the opcode's number
log.memory
has the following methods:
slice(start, stop)
- returns the specified segment of memory as a byte slicelength()
- returns the length of the memory
log.stack
has the following methods:
peek(idx)
- returns the idx-th element from the top of the stack (0 is the topmost element) as a big.Intlength()
- returns the number of elements in the stack
db
has the following methods:
getBalance(address)
- returns abig.Int
with the specified account's balancegetNonce(address)
- returns a Number with the specified account's noncegetCode(address)
- returns a byte slice with the code for the specified accountgetState(address, hash)
- returns the state value for the specified account and the specified hashexists(address)
- returns true if the specified address exists
The second function, 'result', takes no arguments, and is expected to return a JSON-serializable value to return to the RPC caller.
If the step function throws an exception or executes an illegal operation at any point, it will not be called on any further VM steps, and the error will be returned to the caller.
Note that several values are Golang big.Int objects, not JavaScript numbers or JS bigints. As such, they have the same interface as described in the godocs. Their default serialization to JSON is as a Javascript number; to serialize large numbers accurately call .String()
on them. For convenience, big.NewInt(x)
is provided, and will convert a uint to a Go BigInt.
Usage example, returns the top element of the stack at each CALL opcode only:
debug_verbosity
Sets the logging verbosity ceiling. Log messages with level up to and including the given level will be printed.
The verbosity of individual packages and source files can be raised using debug_vmodule
.
Client
Method invocation
Console
debug.verbosity(level)
RPC
{"method": "debug_vmodule", "params": [number]}
debug_vmodule

Client
Method invocation
Console

Examples
If you want to see messages from a particular Go package (directory) and all subdirectories, use:
If you want to restrict messages to a particular package (e.g. p2p) but exclude subdirectories, use:
If you want to see log messages from a particular source file, use
You can compose these basic patterns. If you want to see all output from peer.go in a package below abey (abey/peer.go, abey/downloader/peer.go) as well as output from package p2p at level <= 5, use:
