Introducing Helius’s Solana Devnet Faucet

A Solana Devnet faucet is an important developer tool that allows builders to request a small amount of free Devnet Solana (SOL) tokens for deploying, testing, and optimizing on-chain programs.

We run a staked Devnet validator which earns Devnet SOL emissions. These emissions are then deposited into our Solana faucet, from which developers may request airdrops.

Today, all teams on paid Helius plans can access the Solana Devnet faucet in their dashboard or Solana CLI.

How to Use the Solana Devnet Faucet

Using the faucet from the dashboard UI is easy:

1. Go to your dashboard
2. Click the Faucet tab in the sidebar menu
3. Enter your Solana Devnet wallet address
4. Click “Airdrop 1 SOL”

That’s it!

Make sure your wallet is in developer mode and connected to Solana Devnet to confirm that you received your tokens.

Requesting Devnet SOL from the CLI

Developers may also request Devnet SOL airdrops from the command-line interface (CLI) using the airdrop endpoint.

For instructions, read the How to Get Devnet SOL guide on our docs.

How much Devnet SOL can I request per day?

Teams on paid Helius plans can request a max of 1 SOL every 24 hours.

If you need large amounts of Devnet SOL, please message our support team on Telegram or Discord.

Generally, developers are able to complete tests on Devnet with the SOL they receive through free faucets. However, there may be situations that demand large volumes of SOL (e.g., needing to deploy many programs, testing complex on-chain logic, etc.)

What is the difference between Devnet SOL and Testnet SOL?

Solana Testnet and Devnet are two separate clusters, and therefore their native tokens — Testnet SOL and Devnet SOL — are different.

Devnet is typically used by application developers testing on-chain programs, and Solana Testnet is typically for validator operators.

Currently, our faucet only supports Devnet SOL. If you need Testnet SOL, request tokens from the Solana Foundation’s testnet faucet.

Conclusion

Solana faucets are useful developer tools for testing on-chain programs.

Combined with Devnet RPCs, data streaming services, and APIs, developers building with Helius have access to a full suite of tools for deploying, testing, and optimizing on-chain programs.
