=== Other chains and multi-chain tools ===

The broader cryptocurrency ecosystem includes many chains and protocols: Litecoin, Dogecoin, Zcash, Monero, Ethereum-compatible chains, Tron, Solana, Bitcoin forks, sidechains, rollups, and private chains. Perl modules exist for some of these areas, but coverage is uneven.

For example, MetaCPAN dependency data shows `CryptoTron`, described as a Perl extension for use with the blockchain of the crypto coin Tron, depending on `Bitcoin::Crypto`.<ref>MetaCPAN, “Distributions which depend on Bitcoin-Crypto,” https://metacpan.org/dist/Bitcoin-Crypto/requires, accessed July 3, 2026.</ref> There has also been Perl work around blockchain subscription and API interaction, such as `Net::Async::Blockchain`, whose repository describes support for subscriptions and API interaction with blockchains such as BTC and ETH.<ref>GitHub, “deriv-com/perl-Net-Async-Blockchain,” https://github.com/deriv-com/perl-Net-Async-Blockchain, accessed July 3, 2026.</ref>

This shows the general pattern: Perl can reach many cryptocurrency systems through JSON-RPC, REST, WebSocket, or native-format libraries, but module maturity varies. For production systems, developers must check whether a module is maintained, tested, compatible with current protocols, and safe for the intended use.
