Mandala Chain

Mandala Chain is a Polkadot parachain built with Substrate that supports both EVM and Wasm contract environments, so Solidity teams and ink! teams can both deploy. Consensus pairs proof of authority with Byzantine fault tolerance for deterministic blocks, and a fee allowance pool lets end users transact without first holding the token. Cross-chain traffic runs over cross-consensus messaging, while the identity layer binds government, healthcare and financial accounts to one set of decentralised identifiers and on-chain credentials.

Its rollout centres on Indonesia: IDCHAIN works with the national name registry to turn second-level names into verifiable digital identity entry points, agreements with more than 90 banks and over 20 hospitals put data and transactions on-chain, and a local gold producer is exploring tokenisation of reserves. It won Polkadot parachain auction 64 in April 2024, and its testnet opened in January 2025.
