Initial cross-chain-contracts release to support bridging with LayerZero.
OFTWrapper serves as a proxy for LayerZero's OFT standard, allowing LayerZero to mint and burn tokens as usual, which includes the same AML standards as a same chain transfer. When LayerZero initiates a mint or burn request, the OFTWrapper forwards it to the underlying token contract. For this to work, the underlying token must authorize OFTWrapper to perform minting and burning operations on its behalf.
