Network Details
Connection values for the Mandala testnet: Chain ID, RPC and WebSocket endpoints, explorer URL, and native token.
Mandala maintains a testnet for development and integration work. It runs the same Arbitrum Orbit and AnyTrust stack as mainnet, with two differences: the testnet settles to Sepolia instead of Ethereum mainnet, and gas is paid in KPGT (Kepeng Test) rather than KPG.
Connection details
Use these settings to connect any EVM tool (MetaMask, Rabby, Hardhat, Foundry, ethers, viem) to Mandala Testnet.

Add to your wallet
The setup flow is identical to mainnet. Follow the MetaMask or Rabby walkthroughs and substitute the testnet values from the table above.
Get testnet tokens
You start with 0 KPGT. To send transactions you need KPGT for gas. Claim free testnet tokens from the Faucet.
You can also bridge Sepolia ETH (and supported testnet tokens) into Mandala Testnet through the Arbitrum Portal with the Mandala testnet selected. Sepolia ETH faucets are listed in the Ethereum docs.
What testnet is for
- Deploying and testing contracts before pushing to mainnet.
- Integration work against the real Mandala stack (sequencer, batch poster, AnyTrust DAC, validators).
- Local end-to-end runs that need actual L1 settlement, not a forked node.
What testnet is not for
- Production traffic.
- Anything that depends on KPG balances or KPG-priced fees (testnet uses KPGT).
- Stable economic assumptions; testnet parameters may be reset.
