DeveloperEthereum↔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.
PoS vs Plasma
| PoS Bridge(Recommended) | Plasma Bridge | |
|---|---|---|
| Short Description | DApp Developer's looking for flexibility and faster withdrawals with POS system security | DApp Developer's looking for increased security guarantees with Plasma exit mechanism. |
| Structure | Highly flexible | Rigid, Less Flexible |
| Deposit(Ethereum → Matic) | 3-5 mins | 3-5 mins |
| Withdrawal(Matic → Ethereum) | 1 checkpoint = ~30 mins | 10080 mins or 7 days (Challenge Period) |
| Security | Proof-of-Stake system, secured by a robust set of external validators. | Matic’s Plasma contracts piggybacks on Ethereum’s security with 7 days challenge period. |
| Support Standards | ETH, ERC20, ERC721, ERC1155 and Others | Only ETH, ERC20, ERC721 |
