This repo contains educational (hopefully) examples for handcrafting pay-to-script-hash transactions in Rust.

cltv.rs is inspired by Peter Todd's CLTV demo (see a fork of mine). cltv has two subcommands: create and spend. The former generates a P2SH address such that coins sent to it can be spent by the specified secret key after the specified timeout (an absolute unix epoch).

USAGE:
    cltv --locktime <LOCKTIME> --secret <SECRET_KEY> create

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

The latter generate a transaction that spends an P2SH UTXO to a specified address.

USAGE:
    cltv --locktime <LOCKTIME> --secret <SECRET_KEY> spend [OPTIONS] --address <target> --tx <transaction_hex>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --address <target>
        --tx <transaction_hex>
        --vout <vout>              [default: 0]

See cltv --help for the usage info.

• Use the attached config file to create a regtest for fast testing.
• Make sure the P2SH UTXO is confirmed before trying to spend it. Otherwise you might a non-final error, even the timelock has expired.
