A high-performance EVM-compatible Arbitrum testnet rollup powered by Gelato RaaS, Arbitrum Blueberry enables fast, low-cost development with CGT as the gas token.
Arbitrum Blueberry is a public Arbitrum Nitro EVM testnet rollup hosted on Gelato RaaS, using CGT as the native gas token. It’s designed for dApp prototyping, cross-chain bridge dry runs, and contract/infrastructure benchmarking without mainnet risk. Live performance metrics—average gas cost (in CGT), block speed, TPS, and network activity—are displayed on the official dashboard for side‑by‑side comparison with other networks.
Blueberry is unique as a purpose-built, publicly accessible Arbitrum testnet with turnkey developer tooling (RPC, explorer, faucet) and CGT-based gas for fast, low-cost iteration. Backed by the Arbitrum Nitro sequencer, it delivers sub‑second confirmations and negligible testnet fees while remaining EVM-compatible with Ethereum tooling. Its Gelato RaaS dashboard exposes real-time metrics (avg gas cost, block speed, TPS, activity) so teams can benchmark performance against other testnets and mainnets.
Arbitrum Blueberry uses CGT as the gas token for transaction fees. You can obtain CGT by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge CGT to Arbitrum Blueberry, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Arbitrum Blueberry as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
