@across-protocol/contracts-v2

Contains smart contract suite to enable instant token transfers between any two networks. Relays are backstopped by liquidity held in a central HubPool on Ethereum, which also serves as the cross-chain administrator of all contracts in the system. SpokePool contracts are deployed to any network that wants to originate token deposits or be the final destination for token transfers, and they are all governed by the HubPool on Ethereum.

This contract set is the second iteration of the Across smart contracts which facilitate token transfers from any L2 to L1.
