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
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
SEVS Signatures
Test post-quantum cryptographic signatures
Fast Finality
400ms block times for rapid development
Full RPC Support
Complete API compatibility with mainnet
Program Deployment

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.
