Wallets
The maker pubkey, the connected wallet, and the settlement address.
The maker wallet
A maker is a Solana pubkey. That pubkey is the maker on every venue. Makerbook reads it from the wallet the maker connects.
Connected wallet
Deposits and allowances use the wallet connected on Makerbook. The maker approves a pinned contract from a wallet they control, on the venue's chain, and can revoke that allowance there.
Settlement address
A connected maker can save the settlement address for that venue. That address is the key the venue uses to settle. A settlement address that is already blocked cannot be saved.
