An open testnet blockchain for JumboChain, ProtoJumbo Testnet enables safe developer experimentation and integrations, using JNFTC as native currency on Chain ID 234.
ProtoJumbo Testnet is JumboChain’s public, non‑production network for validating dApps and cross‑chain bridge integrations, using JNFTC as the native gas token. It enables safe end‑to‑end testing of asset transfers, smart contracts, wallets, and infrastructure before mainnet rollout. Key performance metrics (average gas cost, block speed, TPS, and network activity) are dynamic on testnets; consult https://jumbochain.org for current figures when comparing performance.
ProtoJumbo is designed for interoperability testing, providing public endpoints suitable for automated CI pipelines and integration with cross‑chain tooling while using JNFTC for gas in a no‑real‑value environment. It aims to mirror core mainnet parameters so gas pricing, block timing, and throughput behavior are realistic without financial risk. For fair comparisons with other networks, rely on live telemetry (avg gas cost, block time, TPS, activity) from https://jumbochain.org, as testnet numbers are intentionally variable.
ProtoJumbo Testnet uses JNFTC as the gas token for transaction fees. You can obtain JNFTC by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge JNFTC to ProtoJumbo Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select ProtoJumbo Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on ProtoJumbo 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 ProtoJumbo 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 JNFTC on ProtoJumbo Testnet, ensure your wallet is connected to the ProtoJumbo Testnet network, enter the recipient's address, specify the amount of JNFTC to send, review the gas fee, and confirm the transaction in your wallet.
