=== Wallets, keys, and custody caution ===

Perl can be used to generate keys, derive addresses, inspect transactions, or build wallet-adjacent utilities. However, cryptocurrency wallet work is high-risk. Bugs in randomness, encoding, derivation paths, signing logic, password handling, file permissions, or network calls can lead to irreversible loss of funds.

For that reason, Perl’s best role in wallet-related work is often educational, diagnostic, offline, or administrative unless the code has been carefully reviewed and tested. A Perl script that watches balances or decodes transactions is much safer than a hastily written Perl script that holds private keys and signs mainnet transactions.

This caution applies to every language, not only Perl. The difference is that Perl makes it easy to write powerful scripts quickly, so programmers must be especially careful when those scripts touch private keys, seeds, wallets, exchange credentials, or production funds.
