An ICB Testnet blockchain that enables developers to validate transactions and application integrations using ICBT on Chain ID 73114 before mainnet deployment.
ICB Testnet is the public testing network for the ICB blockchain, using the valueless ICBT token for gas so teams can deploy and exercise contracts safely. Its primary use cases are end-to-end dry runs of cross-chain bridge transfers/messages, integration testing for dApps, wallets, and relayers, and rehearsing validator/node operations before mainnet. For comparisons, check the ICB explorer linked at icb.network for average gas cost, median block time, sustained TPS, and address/activity metrics; official benchmark figures were not published as of Sep 2025.
ICB Testnet is unique in its bridge-first focus, optimizing the environment for message passing and transfer orchestration so bridge integrators can validate workflows without mainnet risk. It offers stable public endpoints and test ICBT to enable automated load tests and CI pipelines tailored to cross-chain scenarios. For objective comparison with other networks, monitor average gas fees, block speed, TPS under load, and daily active usage on the ICB explorer; standardized targets are not yet publicly posted as of Sep 2025.
ICB Testnet uses ICBT as the gas token for transaction fees. You can obtain ICBT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ICBT to ICB Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select ICB Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on ICB 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 ICB 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 ICBT on ICB Testnet, ensure your wallet is connected to the ICB Testnet network, enter the recipient's address, specify the amount of ICBT to send, review the gas fee, and confirm the transaction in your wallet.
