I think we should mint to multisig address, rather than treasury.
Otherwise action relative to vceBTC need to have a VIP, which take a lot of time.

Summary
Onboards vceBTC ("Ceffu Custody BTC for Venus"), a governance-controlled accounting mirror for BTC held in Ceffu custody, and creates a Venus Fixed Rate Vault (Institutional Loan Vault) that uses vceBTC as collateral. vceBTC is priced identically to BTCB by cloning BTCB's full oracle configuration.
Ships on both bscmainnet and bsctestnet.
