An EVM-compatible, identity-focused blockchain testnet, Ontology Testnet uses VBFT consensus and ONG gas for fast, low-cost dApp and verifiable credential development.
Ontology Testnet is the public sandbox for the Ontology blockchain that mirrors MainNet features (VBFT consensus, ONT ID, NeoVM smart contracts) while using faucet‑supplied ONG for gas. It’s used to test dApps, decentralized identity and verifiable credentials with ONT ID, data tokenization (DDXF), wallets/nodes, and cross‑chain bridge integrations before mainnet deployment. Typical performance: ~1–2s block times, throughput in the thousands of TPS, and sub‑0.001 ONG average gas for simple transfers, enabling high‑throughput, low‑cost testing.
Ontology Testnet stands out with native decentralized identity (ONT ID) and verifiable credentials at the protocol layer plus a dual‑token model where ONG pays gas and ONT governs, reducing fee volatility for developers. Its VBFT consensus (PoS + BFT + VRF) provides fast finality and ~1–2s blocks, delivering higher throughput (thousands TPS) and tiny fees (often well below 0.001 ONG/tx) compared with Ethereum testnets’ ~12s blocks and double‑digit TPS. For cross‑chain builders, first‑class Poly Network interoperability and generally low, predictable testnet activity reduce congestion risk and simplify end‑to‑end bridge testing.
Ontology Testnet uses ONG as the gas token for transaction fees. You can obtain ONG by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ONG to Ontology Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Ontology Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Ontology Testnet 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 Ontology Testnet 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 ONG on Ontology Testnet, ensure your wallet is connected to the Ontology Testnet network, enter the recipient's address, specify the amount of ONG to send, review the gas fee, and confirm the transaction in your wallet.
