Frequently asked questions

Hedera Previewnet is a publicly accessible pre-release network for Hedera Hashgraph that mirrors mainnet services and HBAR‑denominated fees using test HBAR; it is non‑production and subject to resets. Teams use it to dry‑run bridges, EVM smart contracts, HTS token/NFT flows, HCS messaging, mirror‑node indexing, and SDK/wallet integrations while estimating cost and performance. For benchmarking, expect no blocks and deterministic finality in ~3–5 seconds, capacity in the thousands of TPS (10k+ for consensus messages), and typical transaction fees around ~$0.0001–$0.001 per transfer and ~$0.001–$0.10 per contract call.

Previewnet is unique because it exposes upcoming HIP features and node versions first across Hedera’s hashgraph stack—native tokens (HTS), fair‑ordering aBFT consensus, and EVM—so you can validate mainnet‑like behavior early with predictable, fixed‑fee pricing (no gas auctions). Key comparison metrics: avg fees are fractions of a cent for transfers and usually pennies for contract calls; there are no blocks (finality ~3–5s, no reorgs); throughput is high (thousands TPS; >10k TPS for HCS); and activity ranges from idle to stress‑test bursts depending on release cycles.

Hedera Previewnet uses HBAR as the gas token for transaction fees. You can obtain HBAR by bridging from other chains or purchasing using thirdweb Bridge.

To bridge HBAR to Hedera Previewnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Hedera Previewnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.

To build on Hedera Previewnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.

To add Hedera Previewnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.

To send HBAR on Hedera Previewnet, ensure your wallet is connected to the Hedera Previewnet network, enter the recipient's address, specify the amount of HBAR to send, review the gas fee, and confirm the transaction in your wallet.
