Ethereum + Shibarium Bridge

Moving between two large-scale blockchain networks requires a secure and robust cross-chain bridge, and Shibarium has achieved this by utilizing both Plasma and PoS security to create a trustless and bi-directional transaction environment between Shibarium and Ethereum.

This enables users to transfer tokens between the two networks without any third-party risks or impact on market liquidity. The network bridge is designed to be fast, cost-effective, and flexible, and also serves as a scaling solution. It utilizes a dual consensus architecture (Plasma + PoS platform) to prioritize speed and decentralization, and has deliberately enabled arbitrary state transitions on its sidechains along with EVM support.

When your token crosses the bridge, it does not change its circulating supply:

  • Shibarium mints the same number of tokens (1:1) as a pegged token when a token leaves the Ethereum network.
  • In order to move tokens back to the Ethereum network, they are burned on the Shibarium network and unlocked on the Ethereum network during the process.
