Crypto M&A due diligence: licenses, treasuries, keys and tokens
Buying a crypto business adds problems that ordinary diligence never meets. Regulators may need to approve the new owner before closing, assets exist only as long as someone controls the keys, smart contracts may let a single person change the rules, and token holders can have interests that differ from shareholders'. This deep dive explains those issues, how to verify them and how they shape the closing.

Terms that shape a crypto acquisition
- Crypto-asset service provider (CASP)
- In the EU, a firm authorized under the Markets in Crypto-Assets Regulation (MiCA) to provide services such as custody, exchange or transfer of crypto-assets.
- Qualifying holding
- A stake large enough that MiCA requires the acquirer to notify the regulator and obtain its assessment before acquiring it.
- Proof of control
- Evidence that the seller controls a wallet, usually a message chosen by the buyer and signed with the wallet's private key.
- Multisig or threshold signing
- A wallet that needs several of a defined set of keys to approve a transaction, so no single person can move funds.
- Key ceremony
- A scripted, witnessed procedure for generating, distributing or rotating keys, with a written record of each step.
- Admin key
- A privileged key that can upgrade, pause or reconfigure a smart contract. Whoever holds it can change the rules for every user.
- Vesting release
- The scheduled release of previously restricted tokens to insiders or investors, which can add selling pressure when it lands.
Four deal shapes and where the diligence weight falls
The legal form decides what actually transfers. Identify it first, because each shape puts the risk in a different place.
| Deal type | What changes hands | Heaviest diligence | Closing mechanics |
|---|---|---|---|
| Equity acquisition of a licensed crypto service | Shares in the company holding the licenses and customer relationships | License status, change-of-control approvals, custody of client assets, compliance history | Regulatory approval as a condition; client-asset reconciliation at closing |
| Acquisition of a protocol development company | The team, code copyrights, trademarks and any treasury the company owns | Who controls the deployed contracts, the foundation's role, token holder rights | Admin-key and signer changes; assignment of repositories and domains |
| Token-for-token or token-and-equity merger | Tokens of one project exchanged for another's, sometimes with equity | Tokenomics of both sides, governance votes required, holder treatment | Governance approvals, token migration contracts and exchange coordination |
| Treasury or asset purchase | Specific tokens, wallets or positions | Ownership proofs, encumbrances, lock-ups and provenance of funds | On-chain transfer to buyer-controlled wallets, verified on receipt |
License approvals can set the closing date
Under MiCA, anyone who intends to acquire a holding in a CASP that reaches or exceeds 20%, 30% or 50% of voting rights or capital, or that would make the CASP its subsidiary, must notify the competent authority first1. The authority acknowledges receipt within two working days and has 60 working days to assess, and the clock can stop for up to 20 working days while it waits for information, or up to 30 if the acquirer is outside the Union1.
The assessment looks at the acquirer's reputation and financial soundness, the experience of the people who will run the business, whether the CASP can keep complying with MiCA, and any reasonable grounds to suspect money laundering or terrorist financing1. Prepare that file during diligence, not after signing. In the US, state money transmission laws generally require approval or notice before a licensee changes hands, so a target licensed in many states can face many parallel approvals with different timelines.
Verifying the treasury before signing and again at closing
Balances shown in a dashboard or a spreadsheet are claims. Verify them on-chain, then again on the closing date.
Handing over keys at closing
Share transfer does not move control of a wallet. The signer set has to change, in a sequence both sides rehearse beforehand.
- Buyer key holders
Generate new keys in their own ceremony and share only public keys.
- Closing coordinator
Runs the agreed script and records evidence for the closing file.
- Seller signers
Approve the signer change and then retire their keys.
- Multisig treasury
The on-chain wallet whose signer set changes.
Smart-contract risks an acquirer inherits
One person can upgrade or pause the contracts
Early signalAdmin keys held in a single wallet, with no timelock or multisig.
MitigationRequire a move to multisig control with a timelock before closing, and transfer admin rights as a closing step.
Code changed since the last audit
Early signalThe audit report names an older commit than the one deployed.
MitigationCompare deployed bytecode with the audited version and commission a review of the differences.
Dependence on external price oracles or bridges
Early signalContracts rely on a single price feed or a bridge with its own admin keys.
MitigationAssess the oracle and bridge as third-party dependencies, with their own failure scenarios.
Unresolved past incidents
Early signalExploits, frozen funds or user compensation promises that never completed.
MitigationQuantify outstanding liabilities and cover them with a specific indemnity or holdback.
Financial-crime exposure you can check on-chain
Public ledgers let a buyer trace where funds came from. On-chain analytics can show exposure to sanctioned addresses, mixers or addresses linked to known exploits. OFAC can add digital currency addresses to its sanctions list, and US persons holding blocked virtual currency must deny all parties access to it3. In the EU, the transfer-of-funds rules in Regulation (EU) 2023/1113 extend information requirements to crypto-asset transfers4, so check whether the target collects and passes on the required originator and beneficiary data.

Questions and answers
How long does MiCA approval of a new CASP owner take?
The authority has 60 working days from acknowledging a complete notification, and can stop the clock while it waits for more information, for up to 20 working days or up to 30 for acquirers outside the Union1. Build that into the long-stop date, and prepare the file early so the notification is complete when it is submitted.
How do you prove a seller actually controls its crypto treasury?
Ask the seller to sign a message chosen by the buyer with each wallet's private key, then verify the signatures independently against the published addresses. Combine this with on-chain balance checks at a recorded block height and custodian confirmations for assets held by third parties. Repeat the checks at closing, since balances can move after signing.
Does buying the company that built a protocol mean buying the protocol?
Not necessarily. Deployed contracts may be controlled by a foundation, a multisig of independent signers or nobody at all, and governance may sit with token holders. The buyer acquires what the company owns, such as staff, code copyrights, trademarks and its own treasury. Establish who holds admin keys and governance power before valuing the deal.
