edgeX vs Lighter

The edgeX Bridge tracks the assets users deposit to trade on edgeX, the order book exchange for perpetuals and spot. Funds are held in edgeX contracts across Ethereum, Arbitrum and the edgeX L1, while trades are matched at high speed on the exchange and settled with on-chain custody. The bridged balance is the collateral that backs trading across edgeX products.
