The network will automatically determine the port to connect to, just like the bitcoind and bitcoin-cli commands. Callback support was removed. Since version v0. This comes with the advantage of making the order of arguments irrelevant. It also helps improving the readability of certain function calls when leaving out arguments for their default value. Due to JavaScript's limited floating point precision , all big numbers numbers with more than 15 significant digits are returned as strings to prevent precision loss.

Since Bitcoin Core v0. This enables use-cases such as managing a personal and a business wallet simultaneously in order to simplify accounting and accidental misuse of funds. Historically, the accounts feature was supposed to offer similar functionality, but it has now been replaced by this more powerful feature. To enable Multi Wallet support, start by specifying the number of added wallets you would like to have available and loaded on the server using the -wallet argument multiple times.

For convenience, the bitcoin-core docker image will be used, but it's not a requirement:. Do not copy and paste this hash ever beyond this exercise. By default, all methods are exposed on the client independently of the version it is connecting to. This is the most flexible option as defining methods for unavailable RPC calls does not cause any harm and the library is capable of handling a Method not found response error correctly. However, if you prefer to be on the safe side, you can enable strict version checking.

This will validate all method calls before executing the actual RPC request:. If you want to enable strict version checking for the bleeding edge version, you may set a very high version number to exclude recently deprecated calls:. To avoid potential issues with prototype references, all methods are still enumerable on the library client prototype. Start the bitcoind with the RPC server enabled and optionally configure a username and password:.

These configuration values may also be set on the bitcoin. By default, port is used to listen for requests in mainnet mode, or in testnet and regtest modes the regtest change will be changed to in 0. Use the network property to initialize the client on the desired mode and automatically set the respective default port. You can optionally set a custom port of your choice too.

The RPC services binds to the localhost loopback network interface, so use rpcbind to change where to bind to and rpcallowip to whitelist source IP access. All RPC methods are exposed on the client interface as a camelcase'd version of those available on bitcoind see examples below. For a more complete reference about which methods are available, check the RPC documentation on the Bitcoin Core Developer Reference website.

Batch requests are support by passing an array to the command method with a method and optionally, parameters. The return value will be an array with all the responses.

Note that batched requests will only throw an error if the batch request itself cannot be processed. However, each individual response may contain an error akin to an individual request. These endpoints are also unauthenticated so there are certain risks which you should be aware , specifically of leaking sensitive data of the node if not correctly protected.

Unlike RPC methods which are automatically exposed on the client, REST ones are handled individually as each method has its own specificity. The following methods are supported:. Returns various information about the transaction memory pool. Only supports JSON as output format. Query unspent transaction outputs UTXO for a given set of outpoints.

See BIP64 for input and output serialisation. This client supports SSL out of the box. Simply pass the SSL public certificate to the client and optionally disable strict SSL checking which will bypass SSL validation the connection is still encrypted but the server it is connecting to may not be trusted. This is, of course, discouraged unless for testing purposes when using something like self-signed certificates.

The trade off with stunnel is performance and simplicity versus features, as it lacks more powerful capacities such as Basic Authentication and caching which are standard in reverse proxies. You can use stunnel by configuring stunnel. The key option may be omitted if you concatenating your private and public certificates into a single stunnel.

On some versions of stunnel it is also possible to start a service using command line arguments. The equivalent would be:. A custom logger can be passed via the logger option and it should implement bunyan's log levels.

Currently the test suite is tailored for Docker including docker-compose due to the multitude of different bitcoind configurations that are required in order to get the test suite passing. To test using a local installation of node. Git github. Status Installation Install the package via yarn : yarn add bitcoin-core. Keywords bitcoin bitcoind client request rest rpc.
