2. Get Testnet Tokens

Request free testnet CEL tokens from our faucet. Each request provides 100 CEL (testnet).

Faucet Limits:

  • Maximum: 100 CEL per request
  • Cooldown: 1 request per hour per address
  • Daily limit: 500 CEL per address
Open Faucet

Or use CLI:

celereum airdrop 100 --url https://testnet.celereum.com

3. Quick Start

Install CLI

# Install Celereum CLI
npm install -g @celereum/cli

# Verify installation
celereum --version

Create Wallet

# Generate new SEVS keypair
celereum keygen

# Output:
# Public Key: Cel7xK9m...WqNp2
# Seed saved to: ~/.celereum/id.json

Check Balance

celereum balance --url https://testnet.celereum.com

Send Tokens

celereum transfer \
  --to Cel9mWq...zR5t \
  --amount 10 \
  --url https://testnet.celereum.com

4. SDK Integration

import { Connection, Keypair, Transaction } from '@celereum/sdk';

// Connect to testnet
const connection = new Connection('https://testnet.celereum.com');

// Generate keypair
const keypair = Keypair.generate();
console.log('Public Key:', keypair.publicKey.toBase58());

// Check balance
const balance = await connection.getBalance(keypair.publicKey);
console.log('Balance:', balance / 1e9, 'CEL');

// Request airdrop
const signature = await connection.requestAirdrop(
  keypair.publicKey,
  100 * 1e9 // 100 CEL
);
await connection.confirmTransaction(signature);

5. Testnet Features

6. Important Notes

  • Testnet tokens have no real value and cannot be transferred to mainnet.
  • The testnet may be reset periodically, clearing all accounts and data.
  • Rate limits apply to prevent abuse of network resources.
  • For production applications, always test thoroughly before mainnet deployment.
