Omni Lock is a full-featured Lock, and Mercury intends to gradually support it.
Blog: Omnilock, a Universal Lock that Powers Interoperability
RFC: 0042-omnilock
Mercury is currently known to have built-in support for some Lock Scripts, such as Secp, Acp, Pw, etc. Omni Lock will definitely not be the last Lock to be supported, and there will be new Lock contracts that need to be supported in the future. Therefore, the integration of Omni Lock this time needs to consider the convenience of lock script extension, which requires abstraction of lock script based on the needs of Mercury RPC.
