An EVM-compatible Japan Open Chain testnet using JOCT, with Japanese enterprise validator governance for compliant, low-cost, fast testing of Japan-centric Web3 applications.
Japan Open Chain Testnet (JOCT) is an EVM-equivalent network for testing smart contracts, dApps, and cross-chain bridge flows before deploying to the enterprise-governed Japan Open Chain mainnet. It uses faucet JOCT for gas and is tuned for rapid iteration: typical testnet observations show sub-cent effective gas (<0.001 JOCT for a simple transfer), ~2–5s block times, and practical throughput in the tens–to–low-hundreds TPS with modest, growing daily activity. Common use cases include compliance-sensitive pilots (stablecoins, loyalty/points, enterprise NFTs) and interoperability testing with standard ERC-20/721 assets via MetaMask and familiar Ethereum tooling.
Japan Open Chain Testnet is unique for its Japanese enterprise consortium governance and permissioned validator set, delivering predictable finality, low-fee stability, and Japan-aligned compliance options while remaining fully EVM-compatible. Compared with public L1s like Ethereum (~12s blocks and ~15 TPS), JOCT commonly exhibits faster ~2–5s blocks, negligible faucet gas, and higher sustained throughput, supporting smoother UX for regulated Web3 apps. This combination—enterprise-grade governance plus Ethereum equivalence—helps developers target the Japanese market with compliant, high-performance deployments and straightforward portability from existing Solidity codebases.
Japan Open Chain Testnet uses JOCT as the gas token for transaction fees. You can obtain JOCT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge JOCT to Japan Open Chain Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Japan Open Chain Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Japan Open Chain 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 Japan Open Chain 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 JOCT on Japan Open Chain Testnet, ensure your wallet is connected to the Japan Open Chain Testnet network, enter the recipient's address, specify the amount of JOCT to send, review the gas fee, and confirm the transaction in your wallet.
