Public Litecoin APIs used by OpS Crypt

Documentation of the internet-facing Litecoin network endpoints that power balance, UTXOs, history and broadcast in OpS Crypt LTC. This page is documentation — not a private backend that holds keys.

Important: OpS Crypt is non-custodial. Private keys never go to these APIs. Only public addresses and already-signed transactions are sent over the internet.

APIs públicas de Litecoin usadas no OpS Crypt

Documentação dos endpoints da rede Litecoin na internet que alimentam saldo, UTXOs, histórico e transmissão no OpS Crypt LTC. Esta página é documentação — não é um backend que guarda chaves.

Importante: o OpS Crypt é não-custodial. Chaves privadas nunca vão para essas APIs. Só endereços públicos e transações já assinadas trafegam na internet.
