Proving Wallet Ownership with PrimeVault

can primevault prove wallet ownership? a common question our clients hear from their banking partners and liquidity providers, customers and regulators is “can you prove that you have the legal title of funds in the wallet?” behind that question is a reasonable concern when you send funds from a wallet created and managed in the primevault platform, your bank or counterparty might need to verify who actually controls that wallet they need to correctly establish legal ownership of funds, to make sure they originate from wallets controlled by you and not an exchange or other vasps that maintain commingled treasuries with a substantially different risk profile the short answer is yes , primevault can help you prove ownership of funds to your regulators and counterparties we help you do this using a combination of cryptographic proofs and a formal attestation letter this post explains what "owning" a wallet means in the blockchain context, how we structure your wallets, and the specific evidence we provide to satisfy your compliance requirements 1\ what does it mean to "own" a wallet? unlike with banks, blockchain accounts don’t natively come with attested pdf account statements or paper deeds to prove ownership instead, ownership on chain is defined by who controls the private key linked to a blockchain account (aka wallet address) every wallet address has a unique private key whoever controls that key can move the funds you can prove that you control a wallet by signing a message or transaction that only that key could have created when a regulator asks if a wallet belongs to your company, they are really asking “can you show evidence that you control the keys and approvals for this address in a way we can understand and keep on file?” 2\ how wallets on primevault are structured to understand the proof, it helps to understand the infrastructure primevault provides the infrastructure to manage keys to your wallets; we are not an exchange, and we do not pool your funds with anyone else’s dedicated vaults you create vaults that belong strictly to your legal entity that’s visible on chain (you can see exactly which addresses are being used and for what flows) your policies your specific policies and approvers decide when funds move, who can initiate, who must approve, and what limits exist enforced rules primevault’s secure infrastructure enforces those rules and signs on your behalf, but we cannot move your funds on our own a good mental model think of primevault as the company that builds the safe and installs the alarm system you buy a set of safes and decide which safe to use, you hold the keys, and you decide which rules must be respected before the doors open 3\ the solution two kinds of proof when a counterparty asks for proof, we can provide a bundle of evidence that satisfies both technical teams and non technical auditors a cryptographic proof this is the strongest objective proof possible for any address you operate on primevault, you and your counterparty can agree on an arbitrary message to sign either you or your counterparty requesting to verify ownership can provide the exact message they want signed the signed message from your wallet or a message can be something like “this message confirms that wallet 0xabc… is operated by \[your legal entity] as of \[date] ” you approve this message through your usual governance, and the vault signs it the counterparty’s technical team can then verify the signature off chain they don’t need to broadcast anything to the blockchain they take the message + signature + address and confirm mathematically that the signature could only have been produced by the private key controlling that address we recommend that the verifier (your counterparty) choose the message to be signed and that they include “timely” information, such as the current date, to prevent repurposing of a previously signed message this gives them strong, objective evidence of control at a specific point in time, without ever exposing the private key b the "wallet ownership & control" letter to accompany the digital signature, primevault can issue a formal wallet ownership & control attestation this is a letter designed for lawyers and regulators it typically states your legal entity name and environment the list of wallet addresses configured in your primevault workspace confirmation that these wallets sit inside your dedicated vaults, are governed by your policies, and cannot be moved by primevault staff outside those policies put together the signed message proves "we control this wallet," and the attestation explains "this is how that control is structured " 4\ how this helps with compliance most compliance questions come down to three things can you tie this wallet to a specific regulated entity or customer ? can you show that the funds are not coming from an anonymous omnibus pool ? can you provide a clear audit trail if a regulator asks later? our infrastructure helps you with all this it addresses the regulatory requirements as wallet–entity mapping every vault and address in primevault is attached to your internal identifiers (your legal entity) no commingled pools we can prove that your operational wallets are separate vaults under your control, not a shared pool held by primevault auditability every movement, approval, and policy change is logged you can export history to show exactly what happened, when, and under whose authority need this package for a specific counterparty?
