Tutorial: OpS Crypt LTC

Step-by-step guide: understand the product, public APIs, and how to run the wallet source safely.

Official links

Part A — Product concepts

What OpS Crypt is

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.

What it is not

Not a bank, not an exchange, not MetaMask. MetaMask does not support Litecoin. Trust Wallet can import the same BIP39 seed for LTC.

Where keys live

On the user device, encrypted with a PIN. Public blockchain APIs only see addresses and signed transactions.

Part B — Public APIs on the internet

OpS Crypt talks to open Litecoin APIs already published by third parties:

  • Litecoin Space: https://litecoinspace.org/api
  • BlockCypher: https://api.blockcypher.com/v1/ltc/main
  • Blockchair: https://api.blockchair.com/litecoin

Full endpoint list and live tests: API reference · Playground

Check an address balance (example)

curl -s "https://api.blockcypher.com/v1/ltc/main/addrs/YOUR_LTC_ADDRESS/balance"

Broadcast a signed tx (example shape)

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.

Part C — Run the wallet program (from source)

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.

Create wallet

Set a 6-digit PIN → Create 12-word seed → write it offline → enter the app.

Receive

Copy SegWit (ltc1…) or Legacy (L…) address / show QR. Only send LTC.

Send

Paste destination + amount → app builds & signs locally → broadcasts via the public APIs above.

Backup

Download encrypted .opsjson or export seed/WIF. Store offline.

Part D — Android APK

See documentation/APK.txt and SIGNING.md in the repository.

Safety: Never enter your seed on this documentation site. Only use the local app or APK you built/trust.

Tutorial: OpS Crypt LTC

Guia passo a passo: produto, APIs públicas e como rodar o código com segurança.

Parte A — Conceitos do produto

O que é o OpS Crypt

Carteira Litecoin não-custodial: criar/importar chaves (BIP39/WIF), receber, enviar e fazer backup criptografado.

O que não é

Não é banco, corretora nem MetaMask. MetaMask não suporta Litecoin. A Trust Wallet pode importar a mesma seed BIP39 para LTC.

Onde ficam as chaves

No aparelho do usuário, cifradas com PIN. As APIs da blockchain só veem endereços públicos e transações assinadas.

Parte B — APIs públicas na internet

  • Litecoin Space: https://litecoinspace.org/api
  • BlockCypher: https://api.blockcypher.com/v1/ltc/main
  • Blockchair: https://api.blockchair.com/litecoin

Lista completa e testes: API · Playground

Consultar saldo (exemplo)

curl -s "https://api.blockcypher.com/v1/ltc/main/addrs/SEU_ENDERECO_LTC/balance"

Parte C — Rodar o programa (código-fonte)

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.

Criar carteira

PIN de 6 dígitos → gerar 12 palavras → anotar offline → entrar.

Receber

Copiar endereço SegWit ou Legacy / QR. Envie somente LTC.

Enviar

Destino + valor → assinatura local → transmissão pelas APIs públicas.

Backup

Baixar .opsjson criptografado ou exportar seed/WIF.

Segurança: nunca digite a seed neste site de documentação. Use só o app local ou o APK em que você confia.
