MultiversX Testnet Sovereign Chain

The sovereign chain is a completely independent chain with smart contract processing, ESDT transfers, delegation, staking, governance, guardians and all the features the MultiversX main chain has. It is configurable according to the developer, features can be turned on/off, new features can be added on protocol level.

It is a high performance network capable of processing tens of thousands of transactions per second, and allowing developers to configure features like staking setups, VM configurations, gas and transaction fees, native token and more. The network also has a builtin cross-chain mechanism that facilitates token transfers between the sovereign chain and MultiversX network without relayers. The process ensures seamless interoperability and security through validator verification and proof systems.

Sovereign Chains can choose to have Data Availability and/or Settlement on MultiversX or on other major chains as well.
