Additional info:

SolvBTC.BBN is a price growth ERC20 token, similar to wstETH. Its getValueByShares function (https://etherscan.io/address/0xd9D920AA40f578ab794426F5C90F6C731D159DEf#readProxyContract#F5) reads the relevant net value from the underlying Oracle (https://etherscan.io/address/0x8c29858319614380024093DBEE553F9337665756). The underlying Oracle sets the net value through SetSubscribeNavOnlyMarket (https://etherscan.io/address/0x8c29858319614380024093DBEE553F9337665756#writeProxyContract#F5).

Initial questions from review:

• Can they verify the unverified beacon? https://etherscan.io/address/0xb49de2a621c8540874ae4b2ae9a2e59c948645f1#code
  Response: Verified

• is it correct that this eoa ( https://etherscan.io/address/0x55C09707Fd7aFD670e82A62FaeE312903940013E) is allowed to upgrade the navOracle? If so, is this a particular "setup" (mpc, openzeppelin stuff, or something else)
  Response: Pending upgrade to a multisig.

• This EOA is allowed to upgrade the resolver ( https://etherscan.io/address/0x55C09707Fd7aFD670e82A62FaeE312903940013E )? If so, is this a particular "setup" (mpc, openzeppelin stuff, or something else)
  Response: Pending upgrade to a multisig.
