Install Rust.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Clone the source:

git clone [email protected]:samuelvanderwaal/metaplex_decoder.git

Change directory and install or build with Rust:

cd metaplex_decoder

cargo install --path ./

or

cargo build --release

Create a settings file in a configuration directory in the same directory you run the code.

// settings.json

{
  "network": "https://api.mainnet-beta.solana.com",
  "mint_accounts": ["6RB1jyer1XKJJ6X3RdmoXLV1ixdojXLjsSCsFBPLWsam"]
}

Run the program:

./metaplex_decoder

This will loop over all the specified mint accounts and create a metadata file with all the fields from the Rust Data struct.
