An open developer-focused testnet, Prime Chain Testnet (Chain ID 2099) uses ETH for gas to enable safe smart contract testing and integration before mainnet.
Prime Chain Testnet is a sandbox blockchain network for the Prime ecosystem that uses ETH as the native gas token. Its primary use cases are safe deployment and iteration of smart contracts, dry‑running cross‑chain bridge transfers/message passing, and end‑to‑end QA and monitoring without mainnet cost or risk.
Prime Chain Testnet is optimized for cross‑chain bridge development, providing Ethereum‑style tooling with faucet‑funded ETH for realistic fee modeling and repeatable route simulations. As of Sep 2025, no official performance benchmarks are published—average gas cost, block time, TPS, and network activity figures are not publicly documented and can vary, so teams should measure these in their own tests for apples‑to‑apples comparisons.
Prime Chain Testnet uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge ETH to Prime Chain Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Prime Chain Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Prime 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 Prime 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.
