Ethereum↔Matic Bridge

Matic brings you a trustless two-way transaction channel between Matic and Ethereum by introducing the cross-chain bridge with Plasma and PoS security. With this, users can transfer tokens across matic without incurring third-party risks and market liquidity limitations. The Plasma and PoS Bridge is available on both Mumbai as well as Mainnet.

Matic network bridge provides a scaling solution which is near-instant, low-cost, and quite flexible. Matic uses a dual-consensus architecture(Plasma + Proof-of-Stake (PoS) platform) to optimise for speed and decentralisation. We consciously architected the system to support arbitrary state transitions on our sidechains, which are EVM-enabled.

There is no change to the circulating supply of your token when it crosses the bridge;

  • tokens that leave ethereum network are locked and the same number of tokens are minted on matic network as a pegged token (1:1).
  • To move the tokens back to the ethereum network, tokens are burned on matic network and unlocked on ethereum network during the process.
