The OECD’s Crypto-Asset Reporting Framework (CARF) is the biggest shift in crypto regulation since FATF guidance first landed. Unlike local rules or piecemeal national policies, CARF is a global standard - a blueprint that over 50 countries have agreed to implement, covering tax transparency, cross-border reporting, and the treatment of digital assets.

But while headlines focus on exchanges and custodians, the deeper question is this:

Where does self-custody fit in a reporting world designed around regulated intermediaries?

Accredifi’s view is simple:
CARF doesn’t eliminate self-custody - it makes verifiable ownership more important than ever.

What CARF Actually Is

CARF is the OECD’s global framework for crypto-asset reporting. Its purpose is to stop tax evasion by requiring financial institutions and crypto platforms to automatically share information with relevant tax authorities.

It covers:

exchanges
brokers
platforms offering crypto-to-crypto swaps
custodial wallets
intermediaries facilitating digital asset transfers

CARF requires these entities to report:

user identity
wallet addresses
transaction amounts
acquisition and disposal values
exchange activity
cross-border transfers

In other words: a crypto version of the Common Reporting Standard (CRS).

What CARF Does Not Cover Directly

CARF focuses on intermediaries, not individuals.

It does not directly regulate:

your hardware wallet
your seed phrase
your self-hosted MetaMask
your cold storage
your P2P transfers

Self-custody remains outside the scope of automatic reporting - because there’s no regulated entity to compel.

But that doesn’t mean immigration offices, lenders, accountants, exchanges, or even tax authorities will ignore self-custodied wealth.

CARF changes the expectations around transparency, even if it doesn’t directly regulate the wallet.

The New Problem CARF Creates for Self-Custody

Here’s the hidden consequence:

When exchanges start reporting everything automatically, the only "unverified" wealth left will be self-custodied wealth.

And institutions, from tax offices to private banks, will increasingly ask:

"How do we know you actually own that wallet?"
"How do we know the balance was real at the time of declaration?"
"How do we link this address to you?"

This is where screenshots fall apart.
This is where PDFs fall apart.
This is where "just trust me" collapses completely.

CARF indirectly pushes the world toward a need for cryptographically verifiable self-custody proofs.

CARF + Self-Custody = The Proof Layer Becomes Essential

As CARF reporting becomes standard globally:

Institutions will trust custodial balances (because they’re reported automatically)
Self-custody balances will require active, user-provided proof

In practice, this means:

1. You’ll need a way to prove ownership of your wallet

A signed message is the only durable, trustless method.

2. You’ll need a timestamped, verifiable record of balances

So institutions can match it to tax periods, loan applications, residency requirements, or asset disclosures.

3. You’ll need a method that doesn’t reveal your private keys

Because CARF does not request custody - and offering custody to satisfy verification defeats the point of self-custody entirely.

This is exactly the gap Accredifi fills: proof without surrender.

Why CARF Doesn’t Threaten Sovereignty

CARF isn’t a ban on self-custody.
It’s not a move to criminalise private wallets.
It doesn’t give governments access to your hardware wallet or your keys.

CARF regulates intermediaries, not individuals.

The sovereignty threat isn’t CARF itself, it’s the broken proof process institutions will fallback on if users can’t verify self-custodied wealth properly.

Left unchecked, that leads to:

forced custodial deposits
mandatory intermediary validation
proof derived from exchanges, not users
loss of privacy due to manual documentation
reduced autonomy in global financial interactions

Self-custody verification prevents that outcome.

CARF Makes Accredifi More Necessary, Not Less

As global reporting tightens around custodial activity, the world is dividing into two categories of wealth:

Custodial assets reported automatically
Self-custodied assets that require user-driven verification

This makes verifiable proofs - signed, timestamped, cryptographic - the defining standard for:

immigration and residency applications
tax filings (where self-custody is disclosed)
mortgages using crypto collateral
private equity & venture capital commitments
cross-border declarations
wealth audits for relocation
compliance checks by institutions

Accredifi becomes the bridge: turning sovereign crypto holdings into institution-ready evidence without compromising control.

The Future: A Verifiable but Sovereign Parallel System

CARF formalises the world’s custodial reporting, but self-custody remains the global parallel system, a space where users hold their own keys, control their own wealth, and decide for themselves what to disclose. In this environment, verification becomes the mechanism that allows sovereignty and compliance to coexist.

Crypto wealth is still invisible by default, and CARF doesn’t change that fact. What it does change is the value of being able to prove that wealth in a way institutions can trust without requiring users to surrender control. As more jurisdictions adopt automatic reporting for custodial platforms, self-custodied assets will rely increasingly on user-driven, cryptographically verified proofs.

Self-custody stays sovereign; verification becomes the common language institutions rely on. Accredifi sits at that intersection, providing the infrastructure that makes both sovereignty and institutional recognition possible.
