How Tokenisation Works
From legal wrappers to smart contracts — the complete guide to real-world asset tokenisation
What Is Tokenisation?
Tokenisation is the process of recording ownership rights of a real-world asset — a government bond, a share in a fund, a commercial property, a barrel of oil — as tokens on a blockchain. The token becomes the legally enforceable digital representation of that claim.
The key distinction: the asset itself does not move on-chain. The actual bond, property, or share remains in the real world, typically held by a regulated custodian or within a legal structure such as a special purpose vehicle (SPV). The token is a digital certificate that maps to that real-world holding.
Think of it like a warehouse receipt system: a coffee trader in 17th-century Amsterdam could deposit physical coffee in a warehouse and receive a paper receipt that could be traded without physically moving the coffee. Tokenisation does the same thing with a blockchain ledger instead of paper.
Tokenisation combines the legal certainty of traditional finance with the settlement speed, programmability, and global reach of blockchain rails — enabling 24/7 trading, fractional ownership, and automated compliance in a single system.
The tokenised real-world asset (RWA) market has grown from near-zero in 2020 to over $20 billion in tracked AUM by 2026, with institutions including BlackRock, Franklin Templeton, and HSBC running live issuances. BlackRock's BUIDL fund alone holds over $2 billion in tokenised US Treasury assets.
The Tokenisation Stack
Three layers must work together for tokenisation to function. Think of it as a sandwich: the legal layer on top, the smart contract in the middle, and infrastructure at the base.
- SPV (Special Purpose Vehicle): A standalone legal entity created specifically to hold the asset. Investors receive tokens that represent equity or debt claims on the SPV.
- Fund/Trust structure: For pooled assets like money market funds or ETFs. Each token equals one fund unit.
- Direct registration: For securities, the token can represent a direct entry in the issuer's cap table — more complex, requiring regulatory approval.
- Defines economic rights (dividends, interest, voting), insolvency treatment, and governing jurisdiction.
- Mints tokens when an investor completes KYC and funds arrive in escrow.
- Burns tokens on redemption and releases the underlying cash.
- Enforces transfer restrictions — whitelists, lock-up periods, jurisdictional blocks.
- Distributes yield directly (via stablecoin transfer) or signals yield events to off-chain processors.
- Maintains an on-chain identity registry linking wallet addresses to verified investor identities.
- Custody: Regulated custodians (e.g. BNY Mellon, State Street, BitGo Trust) hold the real-world asset. They provide the proof-of-asset that anchors the token's value.
- Oracles: Price feeds for NAV calculation and mark-to-market valuations — critical for funds and credit instruments.
- Transfer agents: Regulated entities that maintain the official register of ownership; often integrated with the smart contract as the ultimate source of truth.
- Redemption rails: How investors convert tokens back to fiat — typically T+1 to T+2 via bank wire, or instantly if the issuer holds stablecoin reserves.
- Issuance platforms: Middleware providers such as Securitize, Tokeny, Apex, and Superstate that wire these layers together.
A technically perfect smart contract backed by a poorly structured legal wrapper provides no real protection — the token holder may have no enforceable claim in insolvency. Conversely, a robust legal structure with a buggy smart contract creates operational risk. All three layers must be sound.
Asset Categories
Six major asset classes are being tokenised at scale today, each with different risk profiles, liquidity characteristics, and regulatory treatment.
| Category | Examples | Typical Yield | Liquidity |
|---|---|---|---|
| US Treasuries & Govts | BUIDL (BlackRock), OUSG (Ondo), TBILL (Arca) | 4–5% | T+1 redemption |
| Money Market Funds | BENJI (Franklin Templeton), WisdomTree Prime | 4–5% | T+0 to T+1 |
| Equities & ETFs | xStocks, Backed Finance, Dinari | Equity returns | DEX + OTC |
| Private Credit | Maple Finance, Centrifuge, Goldfinch | 8–15% | Lock-up periods |
| Real Estate | RealT, BREV, Elevated Returns | 4–8% + appreciation | Thin secondary market |
| Commodities | PAXG (gold), XAUT (gold), uranium experiments | Spot price exposure | DEX + OTC |
Tokenised treasuries dominate the market today because they combine a well-understood underlying asset (US T-bills) with a straightforward legal structure and strong demand from DeFi protocols seeking yield-bearing, low-risk collateral. The private credit and real estate categories are growing fastest in terms of issuer count, though AUM remains smaller due to lock-up constraints limiting secondary liquidity.
How a Token Is Created
The journey from a real-world asset to a tradeable on-chain token involves nine distinct steps spanning legal, technical, and operational teams.
- 1Asset selection & legal structuring
The issuer identifies the asset and works with lawyers to select the right legal wrapper — SPV, trust, fund — depending on the asset type, target investors, and jurisdiction. This stage typically takes weeks to months and is the longest in the process.
- 2Regulatory filing & approval
Depending on the jurisdiction and investor type, the issuer may need to file an offering document with the SEC (Reg D, Reg S, Regulation A+), FCA, MAS, or another regulator. Many issuances today target accredited/professional investors under exemptions to avoid full registration.
- 3Issuance platform selection
The issuer selects a tokenisation platform (Securitize, Tokeny, Apex, Superstate) that provides smart contract templates, KYC/AML infrastructure, investor portals, and ongoing compliance tooling.
- 4Smart contract deployment
The token contract is deployed on the target blockchain (Ethereum, Polygon, Solana, or a private chain) with compliance rules embedded — whitelist checks, transfer restrictions, jurisdiction blocks. The contract is often audited before deployment.
- 5KYC/AML & investor onboarding
Investors complete identity verification through the issuance platform. Their wallet addresses are added to the on-chain whitelist only after passing all compliance checks. This is the primary ongoing operational overhead for tokenised securities.
- 6Primary issuance (investment → minting)
An approved investor wires fiat (or sends stablecoins) to the issuer's account. Once funds are confirmed, the smart contract mints the corresponding number of tokens directly to the investor's whitelisted wallet address.
- 7Custody confirmation
The underlying asset is purchased and lodged with the custodian. The custodian provides attestation — on-chain or off-chain — that the assets backing the tokens are held in safekeeping. This attestation is the anchor of the token's value.
- 8Secondary market trading
Investors can trade tokens peer-to-peer, on whitelisted DEXs, or through OTC desks — subject to both parties being whitelisted. Liquidity varies enormously by asset class; most tokenised securities have thin secondary markets and investors primarily exit via issuer redemption.
- 9Redemption (token burn → fiat out)
An investor submits a redemption request through the issuer portal. The issuer sells the underlying asset (or draws from reserves), the investor's tokens are burned on-chain, and fiat is wired to the investor's bank account — typically within T+1 to T+2.
Transfer Restrictions & Compliance
Unlike standard ERC-20 tokens, tokenised securities are regulated instruments. The smart contract must enforce securities law in code — something traditional ERC-20 was never designed for.
Compliance is enforced through an on-chain identity registry — a mapping from wallet addresses to verified investor profiles. Before any transfer is executed, the contract checks both sender and receiver against this registry. If either party fails the check, the transaction reverts.
The registry typically encodes:
| Restriction Type | How It Works | Example |
|---|---|---|
| KYC whitelist | Only verified wallet addresses can hold or receive the token | New investor must complete ID verification before receiving tokens |
| Accredited investor status | US investors must prove net worth >$1M or income >$200k | Securitize verifies status; wallet flagged as 'US Accredited' |
| Jurisdiction block | Certain countries or regions are blocked entirely | OFAC-sanctioned countries, retail investors in restricted jurisdictions |
| Lock-up period | Tokens cannot be transferred for N days after issuance | SEC Rule 144 requires 6-month holding period for restricted securities |
| Maximum holder count | Some exemptions cap the number of holders (e.g. Reg D: 2,000) | Contract tracks holder count and reverts transfers that would exceed it |
| Transfer agent approval | Some tokens require human sign-off on each transfer | Used for highly regulated instruments; adds latency but maximum control |
The compliance layer also handles forced transfers — the ability of the issuer or regulator to move tokens between addresses (e.g. in a court-ordered recovery or death/estate situation). This is a legal requirement for tokenised securities that distinguishes them from censorship-resistant cryptocurrencies.
Attempting to issue tokenised securities without proper transfer restrictions exposes the issuer to securities law violations in multiple jurisdictions simultaneously. The permissionless nature of public blockchains makes cross-border enforcement actions particularly complex — regulators in the US, EU, and UK have each brought actions against issuers who failed to implement adequate controls.
Settlement & Custody
Settlement is where tokenisation delivers some of its most tangible efficiency gains — but also where the gap between on-chain ideals and real-world constraints is most visible.
Traditional securities settlement operates on a T+2 cycle: if you buy a stock on Monday, you legally own it on Wednesday. This delay exists because clearing houses need time to reconcile trades, manage counterparty risk, and move cash and securities between custodians.
Tokenised securities can achieve near-instant settlement — once both parties are whitelisted and the transfer conditions are met, the blockchain confirms the transaction in seconds. In practice, most tokenised RWAs don't yet achieve instant settlement because the cash leg of the trade still relies on traditional bank rails.
The ideal model is Delivery versus Payment (DvP) — an atomic swap where the token and the cash transfer simultaneously with neither party bearing counterparty risk. This requires the cash to also be on-chain:
| Cash Rails | DvP Possible? | Settlement Speed | Status |
|---|---|---|---|
| Stablecoins (USDC, USDT) | Yes — atomic on-chain DvP | ~seconds | Live today |
| Tokenised bank deposits | Yes — if on same ledger | ~seconds | Pilot phase (JPM Coin, etc.) |
| Wholesale CBDC | Yes — designed for this use case | ~seconds | Pilot phase (Project Guardian, etc.) |
| Bank wire (SWIFT/SEPA) | No — off-chain cash leg | T+1 to T+2 | Current standard |
Custody in the tokenised RWA context operates at two distinct levels:
First, the underlying asset custody: a regulated, qualified custodian holds the real-world asset — the actual T-bills, the mortgage deeds, the gold bars. Institutional custodians active in this space include BNY Mellon, State Street, Anchorage Digital, and BitGo Trust. They provide regular attestations that the assets exist and are unencumbered.
Second, token custody: the investor holds the tokens in a blockchain wallet — a self-custody hardware wallet, an institutional custody solution (Fireblocks, Copper, Anchorage), or a custodian-managed wallet. The issuer maintains the authoritative mapping between the on-chain token register and the custodian's records.
- • Capital locked for 2 business days
- • Counterparty risk during clearing window
- • Settlement fails cost billions annually
- • Only available during market hours
- • Token + cash swap atomically
- • Zero counterparty risk if on-chain cash
- • Capital available immediately
- • 24/7/365 settlement
Yield Distribution
How a tokenised fund or bond pays its investors is a surprisingly nuanced design decision with significant implications for DeFi composability, tax treatment, and operational complexity.
There are three primary models:
- The cleanest model for money market funds and treasury vehicles.
- Each token's value increases over time to reflect accrued yield — similar to how a fund's NAV per share rises.
- No distributions are made; investors realise gains by redeeming at a higher price than they paid.
- Used by: BlackRock BUIDL, Franklin Templeton BENJI, Ondo OUSG.
- DeFi composability challenge: protocols using these tokens as collateral must query the current price per token rather than relying on a stable 1:1 peg.
- Token holder's wallet balance automatically increases to reflect yield — similar to stETH's model.
- Price stays nominally at $1 (or other peg) making it easy to display and account for.
- More complex to implement; some DeFi protocols struggle with rebasing tokens.
- Tax treatment varies by jurisdiction — each rebase event may be a taxable income event.
- Less common in the RWA space; more common in DeFi yield derivatives.
- Issuer calculates yield owed to each holder based on their token balance at a snapshot date.
- Stablecoins (USDC, USDT) are distributed directly to all whitelisted wallet addresses.
- Most intuitive model but operationally complex — requires processing potentially thousands of wallet addresses.
- Can be automated via smart contract (trustless) or executed manually by the issuer (trust required).
- Creates clear, taxable income events — straightforward for accounting.
- Used by: many real estate and private credit tokens.
Risks & Limitations
Tokenisation introduces new efficiency gains but also layers new risks on top of the traditional risks that already exist in the underlying asset class. Investors and builders need to understand both.
| Risk | Description | Mitigation |
|---|---|---|
| Issuer / counterparty | The token is only as good as the entity backing it. Issuer insolvency can leave token holders with an uncertain legal claim depending on the structure. | Understand the legal wrapper — bankruptcy-remote SPV structures provide stronger protection than direct issuer obligations. |
| Smart contract | Bugs in the token contract can freeze funds, enable theft, or prevent redemptions. Unlike traditional systems, there is no system administrator who can reverse erroneous transactions. | Require audits from reputable firms (Trail of Bits, OpenZeppelin, Quantstamp). Prefer contracts that have operated at scale for extended periods. |
| Regulatory | Sudden reclassification of token standards, jurisdiction-specific enforcement, or changes to exemptions can disrupt operations. | Stay current with regulatory developments; prefer issuers with counsel in all jurisdictions where the token is offered. |
| Liquidity | Secondary markets for tokenised RWAs are thin. Most investors exit via issuer redemption, which may have T+1 to T+5 delays and minimum redemption amounts. | Treat tokenised RWA investments as illiquid unless primary redemption is immediate. Don't rely on secondary market liquidity. |
| Oracle / valuation | For assets without a live price feed (private credit, real estate), token NAV depends on periodic appraisals that may be stale or manipulable. | Understand the valuation methodology; prefer tokens with third-party attestations and frequent NAV updates. |
| Custodian | Failure or fraud at the custodian holding the real-world asset is the existential risk for the token holder. | Prefer tokens backed by regulated, systemically important custodians (BNY Mellon, State Street) with segregated account structures. |
| Legal enforceability | In most jurisdictions, courts have not ruled on the enforceability of on-chain ownership claims in insolvency proceedings. | This risk reduces as case law develops. Prefer structures backed by opinions from top-tier legal counsel in the relevant jurisdiction. |
Every tokenised RWA carries at minimum two distinct risk layers: the underlying asset risk (interest rate risk for T-bills, credit risk for private loans, market risk for equities) plus the tokenisation wrapper risk (legal, smart contract, custodian, issuer operational). Before investing, evaluate both layers independently.
Token Standards
The Ethereum community has developed several token standards specifically designed for tokenised securities, each with different tradeoffs between flexibility, compliance expressiveness, and DeFi composability.
| Standard | Description | Used By | Status |
|---|---|---|---|
| ERC-20 | The base fungible token standard. No built-in compliance features — restrictions must be bolted on via custom logic. | Most tokenised assets use ERC-20 as the base with custom transfer hooks | Universal base layer |
| ERC-3643 / T-REX | "Transfer-Restrict-ERC-20" — the most widely adopted compliance standard. Separates the token contract, identity registry, and compliance module into distinct contracts. Transfer hooks query the compliance module on every transaction. | Tokeny's platform, BUIDL, many institutional issuances | De facto industry standard |
| ERC-1400 | Security token standard with partitions (enabling different share classes within one contract), forced transfers, and issuance/redemption hooks. More expressive than ERC-3643 but more complex. | Earlier institutional issuances, some equity tokens | Declining adoption in favour of ERC-3643 |
| ERC-1404 | Simpler than ERC-1400 — adds a detectTransferRestriction function that returns a status code. Lightweight and easy to implement but limited expressiveness. | Some smaller issuers, Arca TBILL | Active but niche |
| ERC-4626 | Tokenised vault standard — standardises deposit, withdrawal, and yield accounting for yield-bearing tokens. Not compliance-focused but enables composability with DeFi protocols. | Yield-bearing wrappers, DeFi integrations of tokenised treasuries | Growing rapidly for DeFi-facing tokens |
The industry has converged on a two-layer approach: ERC-3643 for compliance enforcement, with an ERC-4626-compatible wrapper for DeFi integrations. This lets the same underlying tokenised T-bill serve both institutional investors (who need compliance controls) and DeFi protocols (which need standardised yield-bearing vault interfaces).
Why It Matters
Tokenisation is not a solution in search of a problem. It addresses concrete inefficiencies in the $500+ trillion global financial system — and creates genuinely new capabilities that did not exist before.
| Benefit | Traditional Finance | Tokenised Finance |
|---|---|---|
| Settlement speed | T+2 (equities), T+1 (US Treasuries) | Near-instant (seconds to minutes) |
| Operating hours | Business hours, weekdays only | 24/7/365 |
| Minimum investment | $100,000+ for institutional funds | $100–$1,000 with fractionalisation |
| Geographic access | Limited by jurisdiction, correspondent banks | Global, subject to compliance |
| Compliance cost | Manual KYC/AML, transfer agent records | Automated, on-chain enforcement |
| Yield distribution | Manual processing, T+1 to T+3 | Automated, near-instant |
| DeFi composability | Not possible — assets are siloed | Tokenised T-bills usable as DeFi collateral |
| Auditability | Periodic reporting, reconciliation required | Real-time on-chain transparency |
The most transformative near-term use case is DeFi composability: a tokenised US Treasury fund like BlackRock's BUIDL can be used as collateral in a DeFi lending protocol, earning T-bill yield while simultaneously backing stablecoin borrowing. This "yield-bearing collateral" model was impossible before tokenisation because real-world assets could not interact with permissionless smart contracts.
Longer term, proponents argue that a fully tokenised financial system — where stocks, bonds, property, and commodities all exist as programmable tokens on interoperable ledgers — would eliminate the vast majority of the operational overhead in financial services: reconciliation between counterparties' records, settlement fails, corporate action processing, and proxy voting complexity.
The realistic near-term picture is more incremental: tokenised treasuries and money market funds will mature and grow as DeFi demand for yield-bearing collateral increases. Private credit and real estate tokenisation will grow as secondary market infrastructure develops. Full tokenisation of public equities at scale remains a long-term project, dependent on regulatory reform in major markets.
