Bitcoin JSON RPC Usage Examples

Authors

From our previous tutorial, we've setup a bitcoin fullnode on the testnet chain and in this tutorial we will use the bitcoin cli as well as the json rpc to interact with our wallet and the blockchain using the curl cli utility.

Bitcoin CLI

Before we get to use the rpc interface, we can use the bitcoin-cli command line utility to browse around. For any documentation on these methods, you can visit chainquery.

To get the current block count:

$ bitcoin-cli getblockcount
2091215

To get some basic info about the first block ever created on the bitcoin blockchain. As the genesis block, it has the index value 0. We can use getblockhas to get the hash value for the first block ever created:

$ bitcoin-cli getblockhash 0
000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943

We can now use getblock with the hash value to retrieve details about the block:

$ bitcoin-cli getblock 000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943
{

}

We can use the nextblockhash to retrieve information about block 1:

$ bitcoin-cli getblock 00000000b873e79784647a6c82962c70d228557d24a747ea4d1b8bbe878e1206

}

We can use -getinfo to get information show as the verification progress and balances in our wallets, should they exist:

$ bitcoin-cli -getinfo
{
  "version": 210100,
  "blocks": 2091215,

  "balances": {
  }
}

JSON RPC

First get the rpc user and password from the bitcoin.conf:

$ cat /etc/bitcoin/bitcoin.conf | grep -E '(rpcuser|rpcpassword)'
rpcuser=bitcoin
rpcpassword=xxxxxxxxxxxxxx

Because this is a test environment, we can set the username and password as an environment variable:

# the user and password might differ on your setup
$ export bitcoinauth="bitcoin:xxxxxxxxxxxxxx"

Wallet Interaction

A wallet is a collection of bitcoin addresses, go ahead and create a wallet named wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "createwallet", "params": ["wallet"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":{"name":"wallet","warning":""},"error":null,"id":"curltest"}

Now list our wallets:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "tutorial", "method": "listwallets", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":["wallet"],"error":null,"id":"tutorial"}

If we inspect the bitcoin.conf we will notice that we don't have the wallet loaded in our config:

$ cat ~/.bitcoin/bitcoin.conf | grep -c 'wallet='
0

But since we created the wallet, we can see the wallet.dat in our data directory:

$ find /blockchain/ -type f -name wallet.dat
/blockchain/bitcoin/data/testnet3/wallets/wallet/wallet.dat

Let's restart the bitcoind service and see if we can still list our wallet, first restart the service:

$ sudo systemctl restart bitcoind

Then wait a couple of seconds and list the wallets:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "tutorial", "method": "listwallets", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":[],"error":null,"id":"tutorial"}

As you can see it's not loaded, due to it not being in the config. Let's update our config /etc/bitcoin/bitcoin.conf, and restart the service:

# more wallets can be referenced by using another wallet= config
[test]
wallet=wallet
# which corresponds to datadir + walletdir
# /blockchain/bitcoin/data/testnet3/wallets/wallet/wallet.dat
# /blockchain/bitcoin/data/testnet3/wallets/wallet/db.log

When I restarted the bitcoind service, I checked the logs with journalctl -fu bitcoind, and I could see the wallet has been loaded:

When I list the wallets again:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "tutorial", "method": "listwallets", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":["wallet"],"error":null,"id":"tutorial"}

Now that the wallet has been loaded, we can get wallet info:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "tutorial", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/ | jq .
{
  "result": {
    "walletname": "wallet",
    "walletversion": 169900,
    "format": "bdb",
    "balance": 0,
    "unconfirmed_balance": 0,
    "immature_balance": 0,
    "txcount": 0,
    "keypoololdest": 1623329789,
    "keypoolsize": 1000,
    "hdseedid": "x",
    "keypoolsize_hd_internal": 1000,
    "paytxfee": 0,
    "private_keys_enabled": true,
    "avoid_reuse": false,
    "scanning": false,
    "descriptors": false
  },
  "error": null,
  "id": "tutorial"
}

Create another wallet, named test-wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "createwallet", "params": ["test-wallet"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":{"name":"test-wallet","warning":""},"error":null,"id":"curltest"}

After we created our wallet, list the wallets again:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "listwallets", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":["wallet","test-wallet"],"error":null,"id":"curltest"}

Now that we have 2 wallets, we need to specify the wallet name, when we want to do a getwalletinfo method for a specific wallet, test-wallet in this case:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | jq .
{
  "result": {
    "walletname": "test-wallet",
    "walletversion": 169900,
    "format": "bdb",
    "balance": 0,
    "unconfirmed_balance": 0,
    "immature_balance": 0,
    "txcount": 0,
    "keypoololdest": 1623333495,
    "keypoolsize": 1000,
    "hdseedid": "x",
    "keypoolsize_hd_internal": 1000,
    "paytxfee": 0,
    "private_keys_enabled": true,
    "avoid_reuse": false,
    "scanning": false,
    "descriptors": false
  },
  "error": null,
  "id": "curltest"
}

Note: If the above command fails because of jq you can install jq or replace it with python3 -m json.tool.

In order to understand where the data resides for our test-wallet, we can use find:

$ find /blockchain/ -type f -name wallet.dat | grep test-wallet
/blockchain/bitcoin/data/testnet3/wallets/test-wallet/wallet.dat

$ find /blockchain/ -type f -name db.log | grep test-wallet
/blockchain/bitcoin/data/testnet3/wallets/test-wallet/db.log

Include the wallet name in the config located at /etc/bitcoin/bitcoin.conf:

[test]
wallet=wallet
wallet=test-wallet

Then restart bitcoind:

$ sudo systemctl restart bitcoind

Now list our wallets again, and you should see they are being read from config and the wallets will persist if your node restarts:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "listwallets", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/
{"result":["wallet","test-wallet"],"error":null,"id":"curltest"}

To backup a wallet, the test-wallet in this case:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "backupwallet", "params": ["test-wallet_bak.dat"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":null,"error":null,"id":"curltest"}

To check where the file was backed up:

$ find /blockchain/ -name test-wallet_bak.dat
/blockchain/bitcoin/data/test-wallet_bak.dat

Addresses

At this moment we have wallets, but we don't have any addresses associated to those wallets, we can verify this by listing wallet addresses using the getaddressesbylabel and passing a empty label as new addresses gets no labels assigned by default.

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": [""]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"":{"purpose":"receive"}},"error":null,"id":"curltest"}

Let's generate a new address for our test-wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getnewaddress", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":"tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc","error":null,"id":"curltest"}

As you can see our address for test-wallet is tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc, note that you can have multiple addresses per wallet.

To get address information for the wallet by using the getaddressinfo method and passing the wallet address as the parameter:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressinfo", "params": ["tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | jq .
{
  "result": {
    "address": "tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc",
    "scriptPubKey": "x",
    "ismine": true,
    "solvable": true,
    "desc": "wpkh([05c34822/0'/0'/0']x)#x3x5vu3t",
    "iswatchonly": false,
    "isscript": false,
    "iswitness": true,
    "witness_version": 0,
    "witness_program": "1eb57750b62dxe284e32cd44f6e49",
    "pubkey": "023a1250c0d44751b604656x649357b5e530b9f8500f03ab5b",
    "ischange": false,
    "timestamp": 1623333494,
    "hdkeypath": "m/0'/0'/0'",
    "hdseedid": "x",
    "hdmasterfingerprint": "x",
    "labels": [
      ""
    ]
  },
  "error": null,
  "id": "curltest"
}

As before, we can view the address by label, to view the address for your wallet, we will now see our address:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": [""]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc":{"purpose":"receive"}},"error":null,"id":"curltest"}

Get available wallet balance with at least 6 confirmations:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getbalance", "params": ["*", 6]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":0.00000000,"error":null,"id":"curltest"}

Get balances (all balances) for the test-wallet wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getbalances", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"mine":{"trusted":0.00000000,"untrusted_pending":0.00000000,"immature":0.00000000}},"error":null,"id":"curltest"}

Create a new address in our test-wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getnewaddress", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":"tb1qa7e0mmgsul6pnxhzx7rw49y9qf35enqqra47hh","error":null,"id":"curltest"}

List all addresses for the wallet:

# by default new addresses has no labels, therefore it returns both
$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": [""]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc":{"purpose":"receive"},"tb1qa7e0mmgsul6pnxhzx7rw49y9qf35enqqra47hh":{"purpose":"receive"}},"error":null,"id":"curltest"}

Labelling Addresses

Now we can label addresses on wallets, to label the first address as "green":

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "setlabel", "params": ["tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc", "green"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":null,"error":null,"id":"curltest"}

Label the new address as "blue":

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "setlabel", "params": ["tb1qa7e0mmgsul6pnxhzx7rw49y9qf35enqqra47hh", "blue"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":null,"error":null,"id":"curltest"}

Now we can list addresses for our wallet by the label, "blue" in this example:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": ["blue"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qa7e0mmgsul6pnxhzx7rw49y9qf35enqqra47hh":{"purpose":"receive"}},"error":null,"id":"curltest"}

List addresses for our wallet by the label "green":

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": ["green"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc":{"purpose":"receive"}},"error":null,"id":"curltest"}

Create another address for our test-walet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getnewaddress", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":"tb1qunk223dztk2j2zqswleyenwu3chfqt642vrp8z","error":null,"id":"curltest"}

Set the new address to the green label:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "setlabel", "params": ["tb1qunk223dztk2j2zqswleyenwu3chfqt642vrp8z", "green"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":null,"error":null,"id":"curltest"}

List addresses by green label:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getaddressesbylabel", "params": ["green"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc":{"purpose":"receive"},"tb1qunk223dztk2j2zqswleyenwu3chfqt642vrp8z":{"purpose":"receive"}},"error":null,"id":"curltest"}

Receive tBTC

You can receive free test btc, by using any of these testnet faucet websites to receive tBTC over testnet:

The transaction details for sending 0.001 tbtc to my tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc address, we will receive the following information:

  • TxID: 637ea98aca23411059ad79aca7ea36ae30b68a173d89e6644703a06a1a846c25
  • Destination Address: tb1qr66hw59k958xrz008n679p8r9n2y7mjfr3tsjc
  • Amount: 0.001

Then to list transactions:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "listtransactions", "params": ["*"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | jq .

As you can see at the time, there were 0 confirmations, we can see the same txid as well as other info. With the testnet, we require at least 1 confirmation before a transaction is confirmed, where the mainnet requires 6.

To get balances for our test-wallet:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getbalances", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"mine":{"trusted":0.00000000,"untrusted_pending":0.00100000,"immature":0.00000000}},"error":null,"id":"curltest"}

As you can see as we don't have any confirmations yet, so therefore the trusted value is still 0.

Listing the transactions over time:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "listtransactions", "params": ["*"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | jq .

Block Explorer

We can also use a blockchain explorer, head over to a testnet blockchain explorer, such as:

And provide the txid, in my case it was this one:

This transaction was done a while ago, so the confirmations will be much more than from the output above, but you can see the confirmations, addresses involved and tbtc amount.

To only get the trusted balance, using the getbalance method and with at least 6 confirmations:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getbalance", "params": ["*", 6]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":0.00100000,"error":null,"id":"curltest"}

Let's send another transaction, the list the transactions using the listtransactions method:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "listtransactions", "params": ["*"]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | jq .

After 12 hours, we can see that we have 102 confirmations for our first transaction and 99 transactions for the second transaction:

After 3 transactions, view the balance in the test wallet using the getbalance method:

$ curl -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curltest", "method": "getbalance", "params": ["*", 6]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":0.04731545,"error":null,"id":"curltest"}

Sending a raw transaction

A easier way to send a transaction is by using sendtoaddress and the source wallet will be in the request url, ie: /wallet/wallet-name

First we look if we have a address for our account that we are sending from, if not then we can create a wallet and a address, for this example, I have a address for the wallet wallet:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getaddressesbylabel", "params": [""]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/wallet
{"result":{"tb1qks4tyrz52vvdh35kcx0ypvnj3fjdkl692pzfyc":{"purpose":"receive"}},"error":null,"id":"curl"}

Ensure that our source wallet has funds in it:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getbalance", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/wallet | python -m json.tool
{
    "error": null,
    "id": "curl",
    "result": 0.01811929
}

We have enough funds to send, so we now have the source wallet name and we need to get the wallet address, where we want to send the funds to, which in this case is the address in test-wallet as the destination:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getaddressesbylabel", "params": [""]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet
{"result":{"tb1qzxmefmcpq98z42v67a80gvug2fe979r5h768yv":{"purpose":"receive"}},"error":null,"id":"curl"}

Just to double check our current funds in the wallet that will receive funds:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getbalance", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/test-wallet | python -m json.tool
{
    "error": null,
    "id": "curl",
    "result": 0.35572584
}

Now we will use the sendtoaddress method, with the recipient address and the amount to send as the parameters. To summarize:

  • Source Wallet: wallet
  • Destination Address: tb1qzxmefmcpq98z42v67a80gvug2fe979r5h768yv
  • Amount to send: 0.01.

Sending the amount:

$ curl -s -u "$bitcoinauth"  -d '{"jsonrpc": "1.0", "id":"0", "method": "sendtoaddress", "params":["tb1qzxmefmcpq98z42v67a80gvug2fe979r5h768yv", 0.01]}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/wallet
{"result":"df087095ac79d678f9d98c8bf8ebface2ac62a20546d85e07a852feb2c3bea50","error":null,"id":"0"}

We will receive a transaction id, and if we list for transactions for our source wallet, we will see the transaction:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "listtransactions", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/wallet | python -m json.tool
{
    "error": null,
    "id": "curl",
    "result": [
        {
            "address": "tb1qks4tyrz52vvdh35kcx0ypvnj3fjdkl692pzfyc",

            "blockheight": 2091275,
            "blockindex": 1,
            "blocktime": 1630677226,
            "category": "receive",
            "confirmations": 1,
            "label": "",
            "time": 1630677177,
            "timereceived": 1630677177,
            "txid": "e44b45a309284e8044a15dca8c0a895a5c7072741882281038fb185cc0c1a0d9",
            "vout": 0,
            "walletconflicts": []
        },
        {
            "abandoned": false,
            "address": "tb1qzxmefmcpq98z42v67a80gvug2fe979r5h768yv",
            "amount": -0.01,
            "bip125-replaceable": "no",
            "category": "send",
            "confirmations": 0,
            "fee": -1.41e-06,
            "time": 1630677743,
            "timereceived": 1630677743,
            "trusted": true,
            "txid": "df087095ac79d678f9d98c8bf8ebface2ac62a20546d85e07a852feb2c3bea50",
            "vout": 0,
            "walletconflicts": []
        }
    ]
}

So when we look at the sender wallet, we will see the funds was deducted:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getbalance", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/wallet | python -m json.tool
{
    "error": null,
    "id": "curl",
    "result": 0.00811788
}

And when we look at the receiver wallet, we can see that the account was received:

$ curl -s -u "$bitcoinauth" -d '{"jsonrpc": "1.0", "id": "curl", "method": "getbalance", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:18332/wallet/rpi01-main | python -m json.tool
{
    "error": null,
    "id": "curl",
    "result": 0.36572584
}
