Creating Multisig Wallet

[rodendron-xrhodium]

This is a small how-to for creating a multisig wallet.

To start XRC node for testing use following start args:

--chain=XRC -server -iprangefiltering=0 -rpcallowip=127.0.0.1 -rpcbind=127.0.0.1 --chain=XRC -server -iprangefiltering=0 rpcuser=*** rpcpassword=*** rpcport=16661 defaultwalletname=multisig1-2of3 txindex=true

Creating Multisig Wallet

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic *****' \
--data-raw '[
    {
        "method": "createmutisigwallet",
        "params": [
            "multisig1-2of3", 
            2,             ["xpub6BvFdAWrvdnASyu41VYvS2Q5P4whhnbLZkd9qv6A1AFwwp5DAZTr3hMKTTDYKBsXfW3bXdrqxGmKhn88tAgzn4ws7otv37uxp9DPrGCZoyL",                "xpub6Cnh2EhE9yAggVwQA7mAy2Reh7hP9VsqVMa7FTBckKUYKwHvi1HPJcqwkuunA5V3LRhCvx8EeKdKoxSRFD2GJQeAd7wawJC1jqJvD2HeP8W"],  
            "trim protect peace young drop area rural choose click begin climb live purchase kick domain only easily arrive model file first mind shed empty", 
            "R8bg2JFXBDtPys2r",
            "R8bg2JFXBDtPys2r"
        ],
        "id": 1525052699893
    }
]'

This should create and store the wallet in file system right place. Trigger wallet synchronisation. This specific wallet will have some xrc coin in mainnet for testing.

To create a raw transaction we use.

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic *****' \
--data-raw '[
    {
        "method": "createrawtransaction",
        "params": [
            "[]",
            "{'\''rcrEgwKijMpSDT2FbS7jCQopr1Kv39jfQs'\'': 0.9999,'\''rVbfxyQWq6SWeDfqVYtqLrCCzK8AR2S3Sw'\'': 1.9999}"
        ],
        "id": 1
    }
]'

This returns transaction hex that’s passed to next RPC call.

To fund & sign multisig transaction we call with all co-signer wallets :

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic ******' \
--data-raw '[
    {
        "method": "fundandsignmultisigtransaction",
        "params": [
            "",
            "01000008000110270000000000001976a9143a25ee63e21887aac3aade9eae0bd67ef8e2b6f788ac00000000",
            "R8bg2JFXBDtPys2r"
        ],
        "id": 1
    }
]'

To switch between other wallets in node we use:

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic ***' \
--data-raw '[
    {
        "method": "setwallet",
        "params": ["multisig1-2of3"],
        "id": 1525052699893
    }
]'

To combine signatures we use:

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic ****' \
--data-raw '[
    {
        "method": "combinemultisigsignatures",
        "params": [           
            [
                "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","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"

To send transaction to network we use:

curl --location --request POST 'localhost:16661' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic ****' \
--data-raw '[{
    "method":"sendrawtransaction",

Thanks this is great, this will help to make a new tab on the UI for multisig once the PR is ready
