Self-Custody & Client-Controlled Wallets
Client-controlled wallets, advisory oversight.
How client-controlled wallet structures can support active digital asset management, and who holds which keys.
In some situations, a client-controlled wallet may be the right structure for digital assets that require on-chain interaction. In those cases, the client controls the wallet and the recovery path. Protocol Wealth’s role is limited by documented permissions, strategy parameters, and human fiduciary oversight.
In a Fordefi wallet there is no single private key. Signing authority is divided into cryptographic shards: Fordefi holds one shard and Protocol Wealth holds one shard. The client holds the ultimate backup, and Protocol Wealth cannot recover the wallet on its own. Assets can be sent only to addresses the client has approved. In a Fordefi wallet, policy changes that expand or alter permissions require the required client and firm approvals.
This structure is designed to separate advisory authority from unilateral control. It remains subject to client agreements, system configuration, compliance review, and legal analysis.
What this page is. A description of how client-controlled wallet workflows can work, and the controls designed to keep the firm in an advisory role. Fordefi and Turnkey are described here as wallet infrastructure — the technology that applies policy and signing rules to a wallet. They are not qualified custodians, and they are not the same thing as the independent qualified custody options described on thequalified custody page.
What this page is not. A personalized recommendation, an offer of any specific wallet or protocol, or a representation that any arrangement is automatically non-custodial, free of risk, or guaranteed for every fact pattern. Whether a client-controlled wallet is appropriate, and how it is configured, depends on the client and is determined under a signed advisory agreement and applicable compliance review.
Section 1
How the controls work
A client-controlled wallet can still be actively managed, because the wallet enforces rules about what is allowed. The design goal is a deny-first posture: activity is blocked unless a specific permission has been approved.
- The default posture is to block activity unless a specific permission is approved.
- Approved permissions can be limited to specific wallets, contracts, strategies, and destinations.
- In a Fordefi wallet, policy changes that expand or alter permissions require the required client approval and firm review.
- Protocol Wealth does not have unilateral authority to withdraw client assets to a Protocol Wealth–controlled wallet.
- The client keeps an independent backup or recovery path so that access does not depend on the firm.
Section 2
Fordefi — MPC wallet infrastructure
Fordefi may be used as institutional MPC (multi-party computation) wallet technology to apply policy rules to a client-controlled wallet — a whitelist-bounded managed sleeve. The client administers the wallet's Rules Policy and holds final approval. The default posture is deny-first: activity is blocked unless a specific permission is approved. The approved allowlist can include third-party and DeFi contracts — for example vaults surfaced through vaults.fyi (such as Morpho, Midas, Lagoon, or Upshift vaults), a DEX like Uniswap, a lending market like Aave or Morpho, or the Across bridge. Within the strategies a client has approved, Protocol Wealth may act on a discretionary basis; where it is simply enabling the client's own wallet to interact with a vault at the client's direction, that step is non-discretionary. Protocol Wealth cannot add destinations or move assets outside the client-approved whitelist, and policy changes that expand or alter permissions require the required client and firm approvals.
Fordefi is wallet and policy infrastructure. It is not a qualified custodian, and using it does not, on its own, make an arrangement non-custodial. Wallet policy engines also have limits — for example, they may not fully inspect nested transaction data in every on-chain interaction — so the firm pairs policy rules with destination allowlists, amount and allowance limits, multi-approver rules for material transactions, and transaction review where needed.
Note on a recent vendor development. Paxos has announced an acquisition of Fordefi. We track this as a vendor and diligence item on ourindustry watch page. It does not, on its own, change the role Fordefi plays in any Protocol Wealth client workflow, and it does not make Fordefi a qualified custodian for client assets. Any change to that characterization would be subject to current agreements, account structure, and compliance and legal review.
Section 3
Turnkey — the self-custodial wallet in the client portal
The portal wallet is built on Turnkey. It is being offered first to selected clients, who turn it on in the client portal. The client is the sole owner of the wallet, which is secured by a passkey on the client’s device. Only the client can move funds or sign. Protocol Wealth never holds the client’s private key and can never sign on the client’s behalf.
Each wallet sits in its own Turnkey sub-organization. The client is its only user and its sole (1-of-1) root. Protocol Wealth has no user, no key and no policy in it, and every email and SMS recovery or sign-in path is turned off. Turnkey is given no client information: the wallet and its user are named with random labels, and no name, email address or client identifier is sent.
An advisor can remove a wallet from the client portal. That sends nothing to Turnkey: the wallet stays under the client’s passkey.
Section 4
Backup and recovery
The portal wallet (Turnkey). Protocol Wealth does not recover wallets. The client’s passkeys are the only way in: if the client loses every passkey for the wallet, the client may lose access to anything held in it. That is why the portal asks the client to use a passkey their device keeps in sync (such as iCloud Keychain or Google Password Manager) and, once the wallet is set up, to add a backup passkey on another device — a security key, or a phone that isn’t signed in to the same passkey manager. A backup kept in the same account as the main passkey is lost along with it.
Fordefi wallets. Where the client engages Coincover, Coincover keeps an encrypted backup of the Fordefi key material. The client completes Coincover’s own process, the decryption key can be delivered only to the client, and Protocol Wealth cannot receive it.
Section 5
Curated information is not a recommendation
Protocol Wealth may surface curated information about vaults, protocols, or opportunities for client review — including information drawn from public sources and surfaced through tools such as vaults.fyi. Surfacing information is not the same as a recommendation to enter any vault or protocol.
A client’s decision to deposit or withdraw through a self-custody workflow remains subject to the client’s own approval and the applicable advisory documentation. Self-custody does not eliminate risk: smart-contract, protocol, bridge, stablecoin, oracle, liquidity, governance, and operational risks all remain, and a client-controlled wallet places real responsibility on the client for the controls they hold.

Versions
The portal wallet is now offered, first to selected clients. What Protocol Wealth holds and does is unchanged: no user, key or policy in the client’s wallet, and no role in recovery.
The Turnkey section describes the portal wallet, which is not yet offered to clients. Protocol Wealth has no user, key or policy in a client’s wallet, and holds no role in a lost-key recovery: the client’s passkeys, including a backup passkey, are the only way in, and Protocol Wealth does not recover wallets. Turnkey is given no client information. Backup and recovery separates the portal wallet from Fordefi wallets, where a client that engages Coincover has an encrypted backup whose decryption key only the client can receive.

This page is general information about how client-controlled wallet workflows can be structured. It is not a personalized recommendation, an offer, or a representation that any arrangement is automatically non-custodial or appropriate for any specific client, and it is not tax or legal advice. Wallet configurations and the firm’s role depend on the client, the assets, and the account, and are subject to compliance, legal, and tax review.
All investments involve risk, including the potential loss of principal. Digital assets are highly speculative and volatile and carry additional risks, including smart-contract, protocol, bridge, stablecoin, oracle, liquidity, governance, cybersecurity, and wallet-policy risk. Past performance does not guarantee future results.
