NanoDrop

Open Source, Transparent and Embedded Nano Faucet

Visit: https://nanodrop.io

This project was created to help bring Nano to the masses.

Faucets are efficient ways to introduce cryptocurrency to new users. Any amount is enough to show the benefits of Nano cryptocurrency: simple, instant, no fees.

NanoDrop is not only another Nano faucet, but the first Nano Open Source Faucet, transparent and integrable through customizable Checkbox and API.

NanoDrop includes:

• Faucet with customizable checkbox.
• QR code reader.
• Nano deposits / donations automatically received.
• Real-time pay table with websockets.
• Anti-spam and anti-bot barriers such as:
  • "Tickets" with amount, ip and timestamp signed using Nano's algorithm
  • Google reCaptcha V2 - forces the user to solve the recaptcha challenge
  • Google reCaptcha V3 - Gives the user a score to ensure they are not a bot
  • Google oAuth - If the user's score is low, it requires login through a Google account
  • Limit per Nano account
  • Limit per IP address
  • Limit per email address
• PoW cache, allowing for always instant transactions.
• Public API for faucet data.

Errors display

If the user exceeds the limits, sends some wrong information or we have an error on the server, the error will be displayed as follows

Calculation of each drop:

Returns 0.01% - 0.1% of the balance, rounded down.

Example: With a balance of 1.145 Nano, returns 0.001 instead 0.00145

Or returns the maximum configured amount, by default = 0.01 Nano.

If there is not enough balance, an error is displayed.

Setting up your instance:

You will need to give:

• An RPC address of a Nano node
• An websockets address of a Nano node
• A Nano worker-server, preferably fast. It can be the same as RPC, but it is recommended use GPU on it.
• Google reCaptcha V2 API Keys
• Google reCaptcha V3 API Keys
• Google oAuth API Keys
• A SEED for the Nano faucet account

Create the .env

cp local.env .env

Now edit the .env file and put in the sensitive data (SEED, API keys). In the "index" it is recommended to leave 0

Edit the config/config.json file and put in the rpc, websockets and worker addresses. You can also edit the "representative" and the "minAmount" - minimum amount Nano (in raws) that can be received; by default 0.000001 Nano

Running in dev mode:

nodemon ./src/init.js

Running in Prod with Docker

chmod +x ./build-docker.sh
sudo ./build-docker.sh

This script will check if Docker is installed and then create the anarkrypto/nanodrop image and the nanodrop container on your system.

If all goes well, you will receive this message:

=> Waiting for API to fully initialize... Done! Open in your browser: http://localhost:3000

For Google reCaptcha and Google oAuth to work you will need to configure your own DNS.
