No. Bonds in traditional finance require legal infrastructure to enforce lending agreements. If a company defaults on their debt, lenders can take them through a process called bankruptcy where their assets are sold to repay creditors. This process relies on legal agreements and law enforcement entities to enforce said legal agreements. However, DAOs don't exist within the bounds of most, if any, legal systems in their current state. Therefore, the enforceability of legal agreements they sign is uncertain and risky. Instead of using legal contracts, Arbor uses smart contracts built on Ethereum to enforce agreements made between lenders and borrowers. Assets supplied as collateral are stored in smart contracts and made available for lenders to claim in the case of a default.
Although OlympusPro and Bond Protocol use the term "bond", they are not selling bonds. Bonds are financial instruments, under which the issuer owes the holders a debt and (depending on the terms of the bond) is obliged to pay them interest (the coupon) and to repay the principal at a later date, termed the maturity date. Bond Protocols bonding mechanism does not require principal to be repaid and therefore can be simplified to selling tokens at a discount with a lockup period. From the OlympusDAO's documentation: [Bonding] allows Olympus to acquire its own liquidity and other reserve assets such as LUSD by selling OHM at a discount in exchange for these assets.
Similar to the OlympusDAO bonds, UMA Range Tokens do not require principal to be repaid. Therefore, when a DAO sells a Range Token, they are not borrowing, they are selling their project tokens with more or fewer tokens being sold depending on the price of their project token at the settlement date.
