What is a faucet

A blockchain faucet is a service that gives out small amounts of cryptocurrency for free—like a faucet dripping drops of crypto instead of water. Faucets are not just about the rewards, they are about learning. Users sign up, solve puzzles to prove they're real, and get a tiny bit of cryptocurrency as a reward.

Remember, faucets offer small amounts and aren't a reliable way to get a lot of cryptocurrency, but they are a great tool to understand how cryptocurrency works and to start your journey in blockchain development.

Why are faucets important

Testnet cryptocurrency, a key component in blockchain development and experimentation, offers a safe and risk-free environment. It allows you to test applications and smart contracts on the test net without using real cryptocurrencies. This feature empowers developers to explore our products and experiment with different features, functionalities, and configurations using testnet tokens, without the fear of losing real cryptocurrencies or impacting the mainnet.

Testnet vs Mainnet

The mainnet, the fully operational network for real-world transactions, and the testnet, a separate version of the network designed for testing, serve distinct purposes. The testnet provides a controlled environment for you to experiment, evaluate, and test our API’s, ensuring the stability and reliability of your applications before they go live. This is where a testnet faucet comes in, a service that distributes testnet tokens for free, allowing developers to access the necessary testing resources.

The testnet mirrors the functionalities of the mainnet (live blockchain) but operates with testnet tokens that hold no real-world value. To acquire these tokens, you can use a testnet faucet, a service that distributes them for free. This ensures a safe environment for your experimentation, as you can freely test and explore without the risk of losing real cryptocurrencies. Each blockchain network typically has its own testnet faucet, making it easy for developers to access the necessary testing resources.

Polygon & Avalanche Faucet

The Faucet feature in Venly's Developer Portal allows users to request MATIC and AVALANCHE tokens for testing purposes on their respective testnets. This feature is designed to facilitate developers in building and testing applications that integrate with these blockchain networks.

What do you get?

When you use Venly's Faucet feature, you can request the following every 24 hours:

• 0.5 MATIC Tokens on the Amoy Testnet chain.
• 0.5 AVAX Tokens on the Fuji Testnet chain.

📘

These tokens are provided to you for testing purposes only and cannot be used on the main networks.

How does this Faucet work?

To request tokens from the Faucet, you need to follow these steps:

1. Access the Developer Portal: Go to Venly's Developer Portal and navigate to Wallet API. Make sure you are under Sandbox. (Click the toggle to change from Production to Sandbox, and vice versa.)

2. Select Token Type: Choose whether you want to request MATIC or AVALANCHE tokens.
3. Provide Wallet Information: Enter your wallet address or wallet UUID associated with Venly. This ensures that the tokens are sent to the correct wallet.

❗️

• Tokens can only be requested using wallets that have been created with Venly.
• Tokens can be requested once every 24 hours.

4. Request Tokens: Click on the "Request tokens" button to submit your request. Tokens will be sent to your wallet shortly after.

5. Tokens sent successfully: You will see a message indicating the tokens were transferred. You can confirm by copying the transaction hash and checking it yourself on:
   1. Polygon Amoy Testnet Explorer
   2. Avalanche Fuji Testnet Explorer

The Faucet feature provided by Venly's Developer Portal is a convenient tool for developers to access test tokens for MATIC and AVALANCHE networks. Following the simple steps outlined above, developers can easily obtain tokens for testing their applications on these networks.

How to use other Faucets

1. Visit the relevant testnet faucet website
2. You may need to sign up for an account or just provide your wallet address
3. Enter your wallet address
4. Some testnet faucets may require solving a CAPTCHA
5. Click the "Submit", "Claim", or "Top Up" button

An example

Here is an example of the Polygon Amoy faucet. This just requires you to paste your wallet address and click Send Me MATIC. After that, the testnet coins will be available in your wallet.

🚧

Your wallet address should be specific to the testnet you are using.
