The Six Cost Components, Defined

Each of the six components below carries its own range, driver, and billing frequency, so a trust officer can pull a single figure into a committee memo without reconstructing the full model. The sections define legal and structuring fees, smart contract development, custody and wallet infrastructure, KYC and AML integration, regulatory and jurisdictional compliance, and ongoing maintenance separately for that reason.

Legal and Structuring Fees

Legal and structuring fees cover the work of building the ownership vehicle that holds the underlying asset and defining how tokens map to legal claims on it. Antier's 2026 analysis puts this layer at $50,000 to $250,000 or more, and three variables move a trust fund's number within that band. The first is jurisdiction. The second is the asset class. The third is the holding structure you choose.
An SPV sits at the low end of the range. You form a single-purpose entity, transfer the asset into it, and issue tokens that represent equity in the SPV. The legal work is contained, and counsel has drafted the same structure hundreds of times. Tokenizing at the trust level costs more because the tokens must reconcile with existing trust deeds, beneficiary rights, and fiduciary duties that predate the issuance. Your counsel reviews and amends governing documents rather than drafting a fresh vehicle from scratch.
Your exemption choice moves the number as much as the structure does. A Reg D 506(c) offering is the lowest-cost path because it requires no SEC qualification, so counsel files a notice and drafts subscription documents for accredited investors. Reg A+ Tier 2 sits at the top of the range. It requires SEC qualification, an offering circular, and ongoing reporting, which adds months of legal time and audited financials before a single token is issued.
For a trust officer building a committee memo, the practical rule is that an SPV wrapped in a Reg D exemption anchors near the $50,000 floor, while a trust-level Reg A+ issuance pushes past $250,000 before any smart contract is written.

Smart Contract Development

Smart contract development covers the code that governs how your token behaves on-chain, from issuance and transfer rules to dividend distribution and investor eligibility checks. The cost splits into three tiers, and the tier you need depends entirely on whether the token represents a regulated security.

A basic tokenization contract, typically an ERC-20 wrapper, runs roughly $10,000 to $30,000 (antier.com). That tier suits a token that carries no transfer restrictions and no investor gating. Almost no trust fund assets qualify, because fund interests, private equity, and real estate held in trust are securities that must restrict who can hold and trade them.

A compliant security token contract costs $30,000 to $150,000 or more. That tier applies to nearly every trust fund issuance because it enforces transfer restrictions and investor eligibility at the contract level. The relevant standards here are ERC-3643, formerly T-REX, and ERC-1400. ERC-3643 embeds identity verification and transfer logic directly into the token, so only whitelisted investors can hold it (liquidmercury.com). ERC-1400 handles partitioned instruments, which matters for tranched debt or fund interests with multiple share classes.

A full custom build runs $100,000 to $500,000 or more, and it fits institutions that need a bespoke compliance engine, automated dividend distribution, and multi-jurisdiction transfer rules in one system. Large trust companies and fund administrators managing several asset classes tend to land here, because packaged standards cannot express their specific eligibility and reporting requirements.

Treat the smart contract audit as a separate line item, not a bundled cost. Both ERC-3643 and ERC-1400 deployments require an independent audit before any capital moves through the contract, and skipping it exposes the issuer to unbounded liability if the code contains a flaw.

Custody and Wallet Infrastructure

Custody covers where and how the private keys controlling your tokenized assets are held, and it splits into two costs that behave differently. The initial setup runs $20,000 to $100,000, covering integration with a qualified custodian, wallet provisioning, and delivery-versus-payment settlement configuration so that tokens and payment change hands atomically. The ongoing charge is a custody fee billed as basis points on assets under management, commonly 10 to 50 bps annually, which scales with the size of the tokenized fund rather than the effort involved (antier.com).

BitGo, Anchorage, and Fireblocks are the institutional providers a trust officer will encounter, and all three build on multi-party computation architecture. MPC splits a private key into separate shares held by different parties, so no single machine or person ever reconstructs the full key. That design removes the single point of failure that a traditional single-key wallet carries, and it is the reason qualified custodians and their insurers treat MPC as the baseline standard for institutional balances (liquidmercury.com).

For a trust holding assets long term, the AUM-based fee matters more than the setup cost over any multi-year horizon. A $50 million tokenized fund at 25 bps pays $125,000 a year in custody alone, which recurs indefinitely, while the setup cost is paid once. Model the custody line as a permanent operating expense, not a launch item, when you take the proposal to the committee.

KYC/AML Compliance Integration

The KYC/AML compliance layer is the on-chain identity and screening infrastructure that verifies every investor before a token transfer clears and monitors activity afterward. Antier estimates the initial build at $15,000 to $80,000, covering the compliance engine, identity attestation integration, and transaction monitoring setup. Providers like Quadrata, Civic, and Synaps issue on-chain identity attestations that a compliance engine references without exposing raw investor data.

The tail costs matter more than the build for a fund that scales. Per-verification fees run $1 to $10 per investor check, and ongoing AML monitoring subscriptions recur monthly. A trust admitting hundreds of qualified investors pays these repeatedly, so the per-check figure compounds faster than the one-time engine cost.

Three regulatory obligations set the floor for what your compliance layer must do. FATF's Travel Rule requires you to transmit originator and beneficiary information with each transfer and avoid anonymous counterparties, which is a technical integration, not a written policy. Under MiCA, a trust company offering custody or transfer services is a CASP and must hold a minimum of its own funds of €125,000 for custody services, scaling to €150,000 for a trading platform.

Weak KYC is the most expensive line item you can skip. Binance paid a $4.3 billion penalty in 2023 for AML and sanctions failures, and OKX drew a $500 million-plus fine in late 2025 for weak KYC and AML controls. Set against an $80,000 build ceiling, those benchmarks make the compliance layer the cheapest insurance in the entire cost model.

Regulatory and Jurisdictional Compliance Costs

Your committee controls this cost before you engage counsel, because the jurisdiction you choose sets the capital floor, the authorization timeline, and the ongoing reporting burden. Pick the wrong one, and you pay for a regime built for a business you don't run.
In the EU, a trust company offering custody, portfolio management, or transfer of tokenized assets falls under MiCA as a crypto-asset service provider and must hold a minimum of its own funds tied to the service. Advisory or order execution requires €50,000, custody or exchange requires €125,000, and running a trading platform requires €150,000, plus your own funds equal to at least a quarter of your fixed overheads (Sumsub). If you issue asset-referenced tokens, the floor rises to €350,000 with full reserve backing. The grandfathering deadline closed July 1, 2026, so new entrants apply directly to a national competent authority.
The UK sits in a transition. FCA registration under the Money Laundering Regulations has been applied since 2020, but the demanding new regime opens its authorization gateway on September 30, 2026, and the full framework starts in October 2027 (Grant Thornton). A trust company launching before 2027 faces regulatory uncertainty rather than a fixed capital number.
In the US, most crypto trust firms register as Money Services Businesses under FinCEN and carry Bank Secrecy Act obligations, while the SEC and CFTC still debate whether tokenized assets are securities under the CLARITY Act. The OCC granted conditional trust charters to five crypto firms in December 2025, so a full national trust bank charter remains rare.
Switzerland's DLT Act offers lower friction. Its ledger-based securities framework recognizes tokenized rights directly under law, which spares you from bending a crypto-asset service regime around a securities issuance.

Ongoing Maintenance and Operations

Your costs do not stop at launch. Once tokens are issued, you carry a recurring stack that continues for the life of the instrument, and it belongs in any cost model you take to committee.

Smart contract maintenance runs $2,000 to $20,000 per month, per Antier's 2026 analysis, driven by upgrade frequency and how much custom logic sits inside the contract. A basic ERC-20 wrapper costs little to maintain. A compliance engine with dividend distribution and transfer restrictions demands ongoing developer attention and periodic re-audits.

AML monitoring adds $1,000 to $10,000 per month for continuous investor eligibility checks and transaction screening. Custody fees are charged as basis points on assets under management, commonly 10 to 50 bps annually, so this line scales directly with the value you tokenize rather than staying fixed.

Gas and transaction fees vary by the chain you settle on, and the choice moves your operating cost more than any other maintenance variable. Ethereum mainnet gas can make frequent transfers expensive. Layer-2 chains such as Polygon, Avalanche, and Base cut those fees to a fraction of L1 costs, which matters when your instrument sees regular secondary trading or scheduled distributions. Selecting an L2 at the architecture stage is a decision the committee should treat as a recurring-cost lever, not a technical afterthought.

Regulatory reporting and audit close the stack at $10,000 to $50,000 per year, covering periodic filings, investor reporting, and the annual review that qualified custodians and regulators expect. Add these five lines together before you present a payback horizon.

"Best For" Categories by Institution Size and Asset Type

Match your institution's profile to a path before you price anything, because your asset mix and compliance ownership needs decide the cost more than any vendor quote.

Single-asset family office tokenizing real estate.

Take the platform path. A single property or real estate fund fits a Reg D 506(c) offering with standard transfer restrictions, and platforms like Brickken handle the ERC-1400 issuance and third-party KYC without custom development. Your all-in cost sits at the low end, and you avoid carrying the compliance infrastructure you would use once.

Multi-asset family office tokenizing private equity and fund interests.

Choose a custom build or an enterprise platform. Private equity carries staggered capital calls, distribution waterfalls, and eligibility rules that generic templates handle poorly. If you plan to tokenize several fund interests over time, a custom compliance engine amortizes better than repeated per-deal platform fees. A single one-off issuance still favors an enterprise platform like Securitize or Tokeny.

Mid-size trust company needing white-label infrastructure.

Use an enterprise platform with compliance pass-through. When you issue on behalf of clients under your own brand, Tokeny's ERC-3643 stack and ONCHAINID identity layer give you MiFID II-aligned transfer validation without building it yourself. The platform absorbs the smart contract audits and standard AML monitoring, and you inherit a maintained compliance layer rather than owning the code.

Large trust company or fund administrator requiring bespoke compliance.

Build custom under a fractional CTO model. Multi-jurisdiction issuance, proprietary transfer restriction logic, and integration with your existing qualified custodian all exceed what a packaged platform will expose. You pay the highest upfront cost, $100,000 to $500,000 for the contract layer alone, but you own the architecture, the compliance decisions, and the vendor relationships outright rather than renting them.

Methodology and Assumptions

The cost ranges throughout this guide come from three sources: Antier's 2026 tokenization cost analysis, Liquid Mercury's RWA tokenization breakdown, and Libertum's platform comparison. No named platform publishes a public fee schedule. Securitize, Tokeny, and Brickken all require direct engagement, and their enterprise or AUM-based pricing appears only in vendor commentary, not price cards.

Two assumptions bound every figure. First, the ranges assume a single-jurisdiction issuance. Multi-jurisdiction structures raise legal and compliance costs beyond the numbers shown here. Second, the custody figures assume a qualified institutional custodian such as BitGo, Anchorage, or Fireblocks rather than self-custody. Treat the ranges as planning benchmarks for a committee memo, not fixed quotes. Your actual cost depends on asset class, exemption choice, and the complexity of your transfer restriction logic.
