    The generation of the data parameter value (the signed transaction data) in this interface can be done in two ways:

    1. Use the ela-cli command line tool, examples are as follows

    ./ela-cli wallet buildtx --from EdAEC51BmmzJFHUdMJ6bR5fZB4oo919E8n --to EgKxcDE1kfEXbpXzwL8eavk6XxMyGEqXmC --amount 10 --fee 0.01

    Please replace the parameter values of --from and --to in the example with the actual ELA Address.

    ./ela-cli wallet signtx -f to_be_signed.txn

    Here you need to enter the password of your local wallet. The long string of hexadecimal characters returned by this command is the signed transaction data.

    1. Use the relevant tools provided by the Elastos.ELA.Utilities.Java tool library to generate specific referenced to the documentation of the repository.
