The moment a US asset manager mints a tokenized money market fund share on Ethereum, a chain of carefully sequenced events fires. A custodian confirms the underlying Treasury holding. A transfer agent updates the share register. A smart contract executes a mint function. A regulated broker delivers the token to a verified investor wallet. The mint completes in seconds. The legal record matches the on-chain record. Tokenization of assets is the operating procedure that holds those two records in alignment.
This guide walks through the mechanics that turn a US dollar Treasury bill, a private credit position, or a money market share into a token on a public or permissioned blockchain. The mechanics matter because the legal status of the token mirrors the underlying asset, and any operational mismatch surfaces as an audit finding, a regulatory matter, or a customer complaint.
The issuance workflow
Tokenized asset issuance follows a six-step workflow. The issuer selects the underlying asset, typically a US Treasury, money market fund share, private credit interest, or real estate position. A regulated custodian or trustee takes custody of the underlying. A legal structure, often a Delaware statutory trust, special purpose vehicle, or 1940 Act fund, holds the asset. A smart contract on the chosen chain represents fractional ownership. A transfer agent maintains the legal share register. A regulated broker-dealer distributes the tokens to investors after KYC checks.
Each step is supervised. The Office of the Comptroller of the Currency has issued interpretive letters confirming that national banks may act as custodians for tokenized assets. The Securities and Exchange Commission supervises broker-dealers distributing tokenized securities and fund administrators handling fund accounting. The Internal Revenue Service treats tokenized fund interests as the underlying for tax purposes.
The chain selection question
US issuers in 2026 choose chains based on settlement properties, regulatory comfort, and investor reach. Ethereum holds the largest share of tokenized US Treasury AUM because of its institutional integrations, custody coverage, and developer base. Solana and Avalanche see growing institutional use for specific products. Permissioned chains like Onyx, Provenance, and Canton Network attract banks that want stricter control over participants.
BlackRock’s BUIDL fund was originally Ethereum-only and has since expanded to several chains to reach more investors. Franklin Templeton’s BENJI launched on Stellar and added Polygon and other chains. Ondo Finance issues across multiple chains in parallel. The trend is multichain issuance with consistent legal structure underneath. The token symbol is the same. The chain hosts are different.
The custody and reconciliation stack
Custody is the operational backbone. The custodian holds the underlying asset, signs attestations for the on-chain supply, and operates the mint and burn functions through controlled access. Reconciliation between the custody record and the on-chain supply runs continuously and is reviewed by external auditors. Big Four accounting firms including PwC, Ernst & Young, KPMG, and Deloitte have all built tokenization audit practices.
| Stage | Typical US provider | Regulatory frame |
|---|---|---|
| Asset custody | BNY Mellon, State Street | OCC, FDIC supervised |
| Token custody | Anchorage, BitGo, Fireblocks | OCC, state regulators |
| Transfer agency | SS&C, internal agents | SEC registered |
| Distribution | Securitize, Ondo, Apex | Broker-dealer license |
| Audit | PwC, EY, KPMG, Deloitte | PCAOB oversight |

The trading and redemption mechanics
Once distributed, tokens can trade on whitelisted secondary markets or be transferred peer-to-peer between approved holders. The smart contract enforces transfer restrictions, which for US securities typically means the recipient must already be on the issuer’s approved list. Redemption happens through the issuer or distributor, with the token burned on-chain and proceeds settled in stablecoin or fiat depending on the product.
For 24-hour redeemability, some tokenized funds maintain stablecoin liquidity buffers managed by the fund’s adviser. Other funds require T plus settlement at the next business cutoff. The choice depends on the fund’s investment mandate and the operational capability of the administrator.
What changes if you are evaluating tokenization in 2026
An institutional investor evaluating tokenized assets in 2026 should ask the same diligence questions as for any registered fund plus a handful of tokenization-specific ones. What chain hosts the token, and what are its finality properties. Who controls the mint and burn functions, and under what governance. How is the underlying asset reconciled against the on-chain supply, and how often. What is the redemption path, including timing and currency. What is the auditor’s opinion on the most recent reconciliation.
For US issuers building tokenization programs, the operational stack is largely off the shelf in 2026. Custody, transfer agency, smart contract development, audit, and distribution can all be sourced from a handful of US-licensed providers. The build versus buy question increasingly tilts toward buy for everything except the legal structure and the investor relationship, which remain core to the issuer’s franchise.
The step that newcomers underestimate is the legal wrapper. On a US deal, the token almost never is the asset by itself. A special purpose vehicle or a fund holds the underlying asset, and the token represents a share or a claim against that entity. Getting this structure right is what makes the token enforceable in a US court, and it is why tokenization projects involve as many lawyers as engineers. The technical ledger is the easy part. The legal plumbing that ties an on-chain record to an off-chain right is the hard part, a point the Bank for International Settlements stresses in its work on tokenized markets at the BIS.
Reconciliation is the other quiet challenge. For now, most tokenized assets exist in two places at once: the blockchain record and a traditional register held by a transfer agent or custodian. Those two have to agree at all times, which means the operating model is not purely on-chain yet. The firms that run this well treat the chain as the system of record and the off-chain books as a mirror, with automated checks that flag any drift between them before it becomes a dispute.
Redemption closes the loop and is where a design is truly tested. A token is only as good as the holder’s ability to convert it back into the underlying asset or its cash value on demand. A clean process makes the token trustworthy. A slow or uncertain one undermines every efficiency gained earlier in the workflow, which is why the most credible US issuers publish exactly how redemption works before they sell a single token.
Control over who can hold a token is built in at issuance rather than added later. Most US tokenized securities are permissioned, meaning only wallets that have cleared identity and eligibility checks can receive them, so the transfer rules of the traditional security carry over to the chain. Price and event data often come from oracles, outside feeds that tell the contract what is happening in the real world. Each of these pieces, the whitelist, the oracle, the custody arrangement, has to be sound, because a tokenized asset is only as trustworthy as the weakest link in the workflow that issues and governs it.
Reporting closes the workflow in a way auditors care about. Because a tokenized asset has to satisfy the same record-keeping standards as its traditional version, issuers build pipelines that turn on-chain activity into the statements an accountant or examiner expects. The chains that win institutional work are the ones that make this straightforward, with clear transaction histories and predictable costs, rather than the ones that are merely fast. In US finance, auditability is not a feature that can be added later; it is a condition of going live at all.
Costs and chain choice interact in ways that decide whether a project is viable. A high-throughput network keeps per-transaction fees predictable, which matters when an asset pays income to thousands of holders and every distribution is a transaction. Issuers model these operating costs before they pick a chain, because a design that is elegant but expensive to run will not survive contact with a US back office that measures everything. The winning setups are the ones that are boring to operate and cheap to reconcile.
Token standards such as those documented at ethereum.org define how these on-chain claims behave. The mechanics described here are stable. The market growth, projected by Citi, BCG, and Standard Chartered toward multi-trillion dollar 2030 totals, is built on workflows that already function inside US financial institutions today.
