Plume (@plumenetwork): RWA Academy: An Intro to Fixed-Income Securities

RWA Academy: An Intro to Fixed-Income Securities Real-World Assets are becoming a lasting part of onchain finance. At Plume we want everyone to understand this new ecosystem, built with traditional assets. The RWA Academy breaks down everything you need to know, from the most basic explanations to more detailed financial concepts. Here, we explain how real-world assets are structured, issued, and legally represented onchain. When assets move onchain, they are held in custody and represented by a token. But what are those tokens backed by in the real world? As discussed in RWA Academy, securities are widely used because they represent enforceable ownership rights. Shares are the most familiar example. Broadly speaking, many debt instruments that provide predictable, stable yield fall under fixed-income securities. Within fixed income, securities can be backed by different underlying assets. Mortgage-backed securities (MBS), made infamous during the 2008 financial crisis, are backed by bundles of residential or commercial real estate loans that generate interest. Corporate bonds are backed by a company’s creditworthiness and cash flows, reflecting its promise to repay borrowed funds with interest. Private credit works similarly, but in private markets. Some fixed-income structures pool non-mortgage assets inside a special purpose vehicle (SPV). The key distinction is that the SPV actually owns the assets. Cars, equipment, or shares may be sold into the SPV and removed from the issuer’s balance sheet, whereas typical debt instruments remain liabilities of the borrower. The blockchain improves transfer, transparency, access, and programmability. But it does not replace legal ownership structures. It connects to them. Understanding RWAs begins with understanding the full chain: the asset backing, the offchain asset, and the onchain token. The Wrapper Behind the Token Most real-world assets cannot simply be split or fractionalized through code. Loans, bonds, and receivables exist within legal contracts and regulated systems. Rewriting those contracts every time ownership changes would be operationally impossible. Instead, assets are typically placed inside a legal entity called a special purpose vehicle (SPV). The SPV legally owns the assets. Investors purchase shares of the SPV, giving them rights to the underlying assets and the yield they generate based on their pro rata ownership. The structure works like this: The asset (e.g., Treasuries or loans) sits inside a legal entity. The entity legally owns the asset. Investors own shares (or tokenized equivalents) in that entity. Returns (yield or asset sales) are distributed based on pro rata ownership. The token is therefore a digital representation of ownership rights that already exist within a recognized legal framework. It links onchain ownership to the economic rights of the underlying assets. Why Not Just Tokenize the Asset Directly? If blockchain can fractionalize tokens, why not fractionalize the asset itself? Most real-world assets exist within contracts, registries, and regulated systems. A bond has a legal issuer. A loan has defined counterparties. A receivable is governed by enforceable agreements. These structures cannot be rewritten every time ownership changes. Funds and SPVs solve this by providing an offchain vehicle to abstract and fractionalize ownership. Instead of modifying the underlying asset, the legal entity owns it. Investors own shares in the entity. Those shares can then be represented as tokens. This preserves: Legal enforceability Risk isolation Defined valuation (NAV) Standardized subscription and redemption Blockchain modernizes transfer. The legal structure preserves ownership. Structure Shapes Risk Before evaluating different RWAs, whether private credit, treasuries, payment financing, commodities, or equities, it’s important to understand how the asset is wrapped. The underlying asset determines what you earn. The structure determines how, when, and whether you can access it. The token you hold onchain is only as sound as the legal structure behind it. Two assets with identical yields can behave very differently depending on how they are wrapped. One might offer daily liquidity; another could lock capital for 12 months. One may sit inside a bankruptcy-remote SPV; another may rely on a corporate balance sheet. Structure determines liquidity, redemption rules, pricing updates, and where legal enforceability sits. Without understanding the wrapper, it is easy to misinterpret how an asset will behave onchain. RWAs depend on this bridge between traditional legal ownership and blockchain infrastructure. Once that bridge is understood, evaluating different asset classes becomes far simpler.

Tokenized assets involve risk and may not be suitable for all participants. Returns, performance and characteristics of traditional financial instruments may not translate identically to their tokenized counterparts. Always conduct your own research and consult qualified professionals before making decisions involving real-world assets or blockchain-based systems.
