An EVM-compatible testnet for self-sovereign identity, Metadium Testnet (Chain ID 12) uses KAL and offers low-cost, Ethereum-tooling-compatible DID smart contract development.
Metadium Testnet is an EVM-compatible network for building decentralized identity (DID) and verifiable credential (VC) applications on Metadium, using KAL as the native test token. It lets teams deploy and validate identity-enabled smart contracts, privacy-preserving KYC/KYB flows, and bridge/wallet integrations with faucet-funded transactions (effective average gas fee ≈ 0 KAL). For performance comparison, check the official explorer for current block time, TPS, and activity, as these vary by validator set and test cycles.
Metadium Testnet is unique for its native DID registry and verifiable credential tooling at the protocol layer, enabling SSI apps with on-chain identifiers and off-chain proofs—capabilities most EVM testnets do not natively offer. It retains full Ethereum tooling compatibility while emphasizing compliance-ready identity workflows and rapid finality for fast iteration. Metrics note: gas is free via faucet on testnet; block speed and throughput are tuned for developer testing rather than sustained public TPS benchmarks.
Metadium Testnet uses KAL as the gas token for transaction fees. You can obtain KAL by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge KAL to Metadium Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Metadium Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Metadium 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 Metadium 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 KAL on Metadium Testnet, ensure your wallet is connected to the Metadium Testnet network, enter the recipient's address, specify the amount of KAL to send, review the gas fee, and confirm the transaction in your wallet.
