Project Harmonia opened its Request for Proposals on September 16.

The initiative is being developed by Allfunds Blockchain and the Solana Foundation to connect two distribution environments that largely operate separately today: Allfunds' institutional network and Solana's onchain markets.

Allfunds says its platform connects more than 3,300 asset managers and financial institutions.

Assets under administration were approximately €1.9 trillion as of June 30, 2026.

That €1.9 trillion is not becoming Solana assets

The number describes the size of Allfunds' existing business, not capital already committed to Harmonia.

No €1.9 trillion migration to a blockchain has been announced.

The project instead creates a distribution route through which selected tokenized funds can become accessible across the two environments.

A fund already operating on Solana can apply for access to Allfunds distribution.

In the opposite direction, an asset manager using Allfunds can seek distribution of a tokenized share class into Solana's Web3 channels and liquidity venues.

Issuing the token is no longer the only difficult part

Representing a fund on a blockchain is now a relatively mature technical problem.

An issuer can build smart contracts, create tokenized shares, connect them to the appropriate records and impose transfer rules.

None of that automatically produces buyers.

A technically sophisticated fund can remain commercially irrelevant if it never appears in the systems used by banks, wealth platforms, funds of funds and institutional distributors.

Harmonia's own framing is blunt: tokenization without distribution is digitization.

Allfunds contributes something a new blockchain project cannot quickly reproduce

The most valuable part of Allfunds is not a smart contract.

It is the network of asset managers, distributors and financial platforms already connected to its infrastructure.

Traditional fund distribution includes product information, subscriptions, settlement, regulatory controls and operational relationships built over many years.

Harmonia is trying to expose part of that machinery to tokenized products rather than forcing every issuer to construct institutional distribution from scratch.

The bridge is designed to work in both directions

The project is not simply about bringing existing Allfunds products onto Solana.

A Solana-native tokenized fund can seek access to Allfunds.

An asset manager coming through Allfunds can also tokenize a share class and distribute it into Solana's onchain ecosystem.

The legal and technical environments remain distinct, but a shared integration layer reduces the need for one-off commercial connections for every product.

Track A is for products that are already live

The first RFP route is intended for tokenized funds already operational on Solana.

They must be functioning products at submission and be seeking institutional distribution.

Harmonia's published requirements call for regulated collective-investment structures such as UCITS, AIFs or other recognized schemes in jurisdictions supported by Allfunds.

Potential strategies include money market, fixed income, equities, private equity, private debt and real assets.

Track B creates a pipeline for products still being built

The second route accepts tokenized funds in development or waiting for regulatory approval.

Those issuers can enter a longer pipeline instead of waiting until every element is complete.

The Solana Foundation describes rolling consideration over roughly six to twelve months for this category.

That allows distribution, technical integration and regulatory preparation to develop alongside the fund itself.

Applications close October 24

The RFP opened September 16 and closes October 24, 2026.

Project Harmonia then lists due diligence during October and admission decisions in November.

The detailed RFP portal targets Q1 2027 for the first selected funds to go live through the Allfunds network via Solana.

Solana's announcement uses a broader Q4 2026 to Q1 2027 window for the first cohort.

Q1 2027 is therefore the most specific public go-live milestone currently published by the program itself.

Admission requires considerably more than minting a token

The evaluation criteria look familiar to traditional fund distribution.

They include domicile, regulatory authorization, eligible investor classes, disclosure, reporting, liquidity, settlement arrangements, investor protections and operational service providers.

Blockchain adds another set of requirements.

For Track A, the product must already be operational on Solana.

Upgrade-authority arrangements have to be documented.

Where custom onchain infrastructure is used, Harmonia requires at least one independent security audit from a recognized firm, with the audit published and the infrastructure open sourced.

Particula provides an independent risk layer

Tokenized funds seeking admission require a Particula rating under the firm's Digital Asset Risk Framework.

The framework examines economic, legal, operational and technical dimensions and produces both a risk assessment and data-confidence score.

Applicants without an existing rating can be evaluated during the RFP process.

That assessment then becomes a primary analytical input into the admission decision.

ioBuilders supplies the integration layer

Technical implementation is supported by ioBuilders through its Asseto platform.

Allfunds describes Asseto as the layer connecting Allfunds Blockchain with onchain environments.

It supports token issuance and lifecycle management while retaining the operational and compliance controls expected by financial institutions.

That abstraction matters because a distributor does not want to rebuild its operating systems for every smart contract used by every issuer.

Institutional tokenization still keeps many traditional restrictions

Putting a fund on a public blockchain does not necessarily mean any wallet can buy it.

A UCITS, AIF or another regulated investment product still has rules around jurisdiction, investor eligibility, subscriptions and transfers.

Smart contracts can encode or automate parts of those controls, but they do not erase them.

Harmonia explicitly evaluates target jurisdictions and investor eligibility before admission.

DeFi access remains constrained by the legal structure of the fund

Allfunds and Solana describe a commercial bridge between traditional finance and decentralized finance.

That does not mean every admitted fund will instantly become permissionlessly tradable across every DeFi application.

Secondary-market use, collateralization or liquidity integration will depend on the fund's legal restrictions, token controls and the services willing and permitted to support it.

Onchain distribution can become more composable without becoming legally unrestricted.

Solana says it already hosts more than $4 billion in institutional RWAs

The Solana Foundation points to an existing base of institutional real-world assets as one reason for the network's selection.

Its Project Harmonia materials cite more than $4 billion in institutional RWAs onchain.

They also cite more than $17 billion in stablecoin float and approximately 2.2 million monthly active wallets.

Those are ecosystem figures published by Project Harmonia and Solana rather than independently audited figures in this announcement.

Their relevance is that Allfunds is connecting to an environment where financial products and settlement assets already exist rather than an empty experimental network.

Blockchain may change settlement without eliminating the businesses around a fund

A tokenized security can record ownership and transfers on infrastructure that operates continuously.

The fund still has a manager, transfer agency processes, valuation, compliance, custody and reporting requirements.

Harmonia is not attempting to replace all of those functions with Solana.

Its architecture is intended to connect existing institutional operations to an additional distribution and settlement layer.

That is why Allfunds emphasizes that institutions do not need to re-platform

A bank or wealth platform has little incentive to throw away its existing technology stack merely to experiment with tokenized funds.

Harmonia instead promises parallel distribution.

Distributors can expose tokenized products through existing operating environments.

Asset managers can keep familiar institutional workflows while adding an onchain channel.

Blockchain becomes an extension of the distribution system rather than an immediate replacement for it.

Distribution may be harder to solve than issuance

The first wave of institutional tokenization concentrated heavily on proving that funds, bonds and other assets could technically exist on blockchains.

That produced a large number of pilots.

The more difficult second step is demand: eligible investors, platforms willing to display the product, liquidity and operational systems capable of processing it.

Harmonia's thesis is that connecting tokenized assets to a mature distribution network may be more useful than creating another bespoke marketplace for each issuance.

That is where the €1.9 trillion figure becomes meaningful again

It is not the amount promised to Solana.

It measures the scale of the distribution machine Solana is attempting to connect to.

If only a handful of products use Harmonia, the immediate effect will remain modest.

The structural experiment is whether tokenized funds can stop rebuilding distribution from zero every time a new product launches.

The first useful evidence will therefore arrive after the November admission decisions: which funds are selected, where they can actually be distributed, and what volume reaches the system when the first cohort goes live in 2027.
