How does liquidity bridge work?

The mechanism for liquidity bridge is simple to understand. Similar to Uniswap’s pair liquidity provider, the 0xTrade Swap liquidity bridge has liquidity providers on each side of the bridge.
The depth of liquidity on each chain for each asset represents the quota for cross chain on destination chain.
To be a liquidity provider, you only need to stake your token on one side of the bridge (You do not need to provide liquidity on both sides of the bridge)
