[Across protocol](https://across.to/) is a novel bridging method that combines an optimistic oracle, bonded relayers and single-sided liquidity pools to provide decentralized instant transactions from rollup chains to Ethereum mainnet.

#### Instantaneous Liquidity

Assets are bridged and available for use on mainnet almost instantly.

#### Secure

Powered By UMA protocol. Transfers are secured by UMA's Optimistic Oracle, which is audited by OpenZeppelin and trusted by top teams to protect hundreds of millions of dollars in value.

#### Cheap

Relayers and liquidity providers are compensated with fees from users initiating transfers, but this fee is less than any other solution on the market.
