Step-by-step guide: understand the product, public APIs, and how to run the wallet source safely.
A non-custodial Litecoin-only wallet project. You create or import keys (BIP39 / WIF), receive LTC, send LTC, and back up an encrypted vault file.
Not a bank, not an exchange, not MetaMask. MetaMask does not support Litecoin. Trust Wallet can import the same BIP39 seed for LTC.
On the user device, encrypted with a PIN. Public blockchain APIs only see addresses and signed transactions.
OpS Crypt talks to open Litecoin APIs already published by third parties:

curl -s "https://api.blockcypher.com/v1/ltc/main/addrs/YOUR_LTC_ADDRESS/balance"
curl -s -X POST "https://api.blockcypher.com/v1/ltc/main/txs/push" \
-H "Content-Type: application/json" \
-d "{\"tx\":\"SIGNED_HEX_HERE\"}"
Never send private keys in these requests.
git clone https://github.com/elevbit-ai/ops-crypt-ltc.git cd ops-crypt-ltc npm install npm run dev
Open the local URL shown by Vite (usually http://localhost:8080). That is the program UI.
Set a 6-digit PIN → Create 12-word seed → write it offline → enter the app.
Copy SegWit (ltc1…) or Legacy (L…) address / show QR. Only send LTC.
Paste destination + amount → app builds & signs locally → broadcasts via the public APIs above.
Download encrypted .opsjson or export seed/WIF. Store offline.
See documentation/APK.txt and SIGNING.md in the repository.

Guia passo a passo: produto, APIs públicas e como rodar o código com segurança.
Carteira Litecoin não-custodial: criar/importar chaves (BIP39/WIF), receber, enviar e fazer backup criptografado.
Não é banco, corretora nem MetaMask. MetaMask não suporta Litecoin. A Trust Wallet pode importar a mesma seed BIP39 para LTC.
No aparelho do usuário, cifradas com PIN. As APIs da blockchain só veem endereços públicos e transações assinadas.

git clone https://github.com/elevbit-ai/ops-crypt-ltc.git cd ops-crypt-ltc npm install npm run dev
Abra a URL local do Vite (em geral http://localhost:8080). Essa é a interface do programa.
PIN de 6 dígitos → gerar 12 palavras → anotar offline → entrar.
Copiar endereço SegWit ou Legacy / QR. Envie somente LTC.
Destino + valor → assinatura local → transmissão pelas APIs públicas.
Baixar .opsjson criptografado ou exportar seed/WIF.
