Onchain vaults encode the same fund operations (deposits, net asset value calculation, fee collection, redemptions) into smart contracts instead of manual processes. The result: settlement in hours instead of days, fees computed automatically instead of quarterly, and a fully auditable record that replaces periodic reports.
## Introduction
A $500 million fund pays $250,000 to $750,000 per year for administration services: net asset value (NAV) calculation, investor communications, fee reconciliation, and regulatory reporting. Most of this cost is driven not by the complexity of the work, but by the manual coordination required between four or five separate counterparties. Launching the fund in the first place takes 4 to 12 weeks of legal setup, admin onboarding, and service agreements before a single dollar is deployed.
Onchain vaults change this. By encoding fund operations into smart contracts, they compress settlement from days to hours, automate fee computation at every cycle, and produce a fully auditable record that replaces quarterly reports. JPMorgan's MONY fund, BlackRock's BUIDL ($2.9 billion across seven blockchains), and State Street's SWEEP on Solana are already running production capital through this infrastructure.
Here is what specifically changes when fund administration moves from manual processes to smart contracts, for institutional managers evaluating the shift.
## How traditional funds actually operate
To understand what onchain vaults change, it helps to map the traditional fund lifecycle clearly. A typical investment fund relies on a chain of intermediaries, each handling a specific piece of the process.
### The intermediary chain
When an investor subscribes to a traditional fund, their capital passes through multiple entities before being deployed:
- **The investor** submits a subscription document, typically via paper or email, along with KYC documentation.
- **A transfer agent** records the allocation, maintaining the fund's shareholder registry.
- **The fund administrator** calculates the net asset value, reconciling positions across databases and pricing sources.
- **A custodian** holds the underlying assets and processes settlement via wire transfer.
- **The portfolio manager** finally deploys the capital into the investment strategy.
A single deposit can touch four or five separate entities before it is reflected in the investor's position. Each handoff introduces latency, cost, and reconciliation risk.
*Figure 1: The traditional fund lifecycle, five entities, multiple handoffs, and 2-3 days to confirm a single deposit.*
### The cost of manual administration
Traditional fund administrators charge 10 to 25 basis points of AUM annually for services that include NAV calculation, investor communications, regulatory reporting, and fee processing. For a $500 million fund, that translates to $500,000 to $1,250,000 per year in administration costs alone.
These costs are not driven by complexity of the calculations; they are driven by the manual nature of the processes: reconciling data across fragmented systems, generating reports from siloed databases, and coordinating between multiple counterparties on different timelines.
## What onchain vaults replace
An onchain vault does not eliminate the need for fund management. Someone still makes investment decisions, someone still provides valuations, and investors still need to be onboarded. What changes is the execution layer. The roles persist, but the manual processes become programmable.
### The smart contract as operations hub
In an onchain vault built on the ERC-7540 standard (the async extension of ERC-4626), the vault smart contract handles:
- **Deposit and redemption processing.** Investors submit requests onchain. Assets are locked until settlement, then shares are minted at the forward price (the NAV calculated at settlement, not at the time of the deposit request).
- **NAV and valuation.** A designated valuation provider submits updated total asset values. The curator accepts valuations and triggers settlement.
- **Fee computation.** Management and performance fees are calculated automatically at every settlement, with high-water mark tracking built into the contract.
- **Governance enforcement.** Role-based permissions (vault administrator, curator, valuation provider, whitelist manager) are enforced onchain, creating separation of powers equivalent to institutional internal controls.
Lagoon's Vault Factory implements this architecture out of the box — managers deploy a production-ready ERC-7540 vault with all four governance roles configured, without writing contract code or negotiating service agreements.

### Mapping TradFi roles to onchain equivalents
| Traditional Role | Onchain Equivalent | What Changes |
|---|---|---|
| **Fund Administrator** | Valuation Provider | NAV submitted via oracle, verified onchain |
| **Transfer Agent** | Vault Smart Contract | Share registry is the ERC-20 token ledger |
| **Custodian** | Multisig / MPC Wallet | Flexible custody: Safe, Fireblocks, Fordefi |
| **Portfolio Manager** | Curator | Executes strategy, accepts valuations, settles |
| **Compliance Officer** | Whitelist Manager | KYC gatekeeping via onchain access control |
Onchain vaults do not remove the roles; they change how the roles are executed. A curator still makes investment decisions. A valuation provider still submits prices. But the coordination between them happens through a smart contract rather than through emails, spreadsheets, and wire transfers.
## What changes in practice
With these roles mapped, the next question is: what changes operationally across the dimensions that matter most to institutional managers? The differences are not cosmetic. They affect the speed, cost, transparency, and operational model of running a fund.
| Dimension | Traditional Fund | Onchain Vault |
|---|---|---|
| **Launch Time** | 4-12 weeks: legal setup, admin onboarding, service agreements, compliance review | Minutes: deploy via Vault Factory, no approvals, no minimum TVL |
| **NAV Calculation** | Daily, by fund administrator using spreadsheets and manual reconciliation | Per settlement cycle, by designated valuation provider with onchain verification |
| **Settlement** | T+1 to T+3: wire transfers, custodian processing, transfer agent recording | Near-instant once valuation is accepted; async flow handles real-world delays |
| **Fee Collection** | Quarterly invoicing, manual calculation, reconciliation between fund and admin | Automated at contract level, computed every settlement with HWM tracking |
| **Reporting** | Monthly or quarterly statements, periodic external audits | Real-time onchain data, publicly verifiable transaction history |
| **Custody** | Third-party custodian (single entity), limited operational flexibility | Multisig, MPC, or smart contract custody: choose based on compliance needs |
| **Audit Trail** | Internal records, annual external audits, trust-based verification | Complete onchain transaction history, independently verifiable by anyone |
### Launch time
Traditional funds require 4 to 12 weeks for legal setup, administrator onboarding, and service agreements. With platforms like Lagoon, deploying a vault takes minutes via a permissionless Vault Factory, with no team approvals, no minimum TVL, and no partnership agreements. This does not eliminate the legal work for regulated products, but it removes the infrastructure bottleneck.
### Settlement
Traditional settlement runs on T+1 to T+3 timelines, involving wire transfers between banks, custodian processing, and transfer agent recording. Onchain vaults using the ERC-7540 async pattern process settlement in hours: requests are submitted, the valuation provider proposes a NAV update, the curator accepts and settles, and investors claim their shares. The async design accommodates real-world delays (off-chain assets, compliance checks) without the manual overhead.
### Transparency and audit
In traditional structures, investors rely on administrator reports that arrive monthly or quarterly. Portfolio breakdowns, fee calculations, and transaction histories are internal, verified only through periodic external audits. In an onchain vault, every transaction, fee, and allocation is recorded on a public ledger. Investors do not need to trust the report; they can verify it independently, in real time.
- **Onchain vaults encode the same fund operations into smart contracts:** deposits, NAV, fees, redemptions, and governance all execute programmatically instead of manually.
- **Settlement compresses from days to hours:** ERC-7540's async pattern handles real-world delays while eliminating manual intermediary handoffs.
- **Transparency is structural, not periodic:** every transaction, fee, and allocation is recorded on a public ledger and independently verifiable.
- **TradFi roles map directly to onchain equivalents:** fund administrators become valuation providers, transfer agents become token registries, and custodians become flexible (multisig, MPC, or smart contract).
- **Major institutions are already in production:** JPMorgan, BlackRock, State Street, and Franklin Templeton all operate live tokenized funds onchain.
