02 · Evoke Lens
One read-only view of every structure.
Lens connects to on-chain wallets and multisigs, to custodians and exchanges, and to bank accounts on a read-only basis. It maps each holding to its structure and prepares a record the fiduciary can sign.
01
Connect, read-only
Add on-chain wallets and multisigs, custodian and exchange accounts, and bank accounts on a read-only basis. Lens can view balances only. It cannot move funds.
Works with your existing custody
02
Map to structures
Assign each holding to the structure it is held for, and record who can move it: the keys, signatories and approvers on each asset line.

03
Report and sign off
Lens prepares a Corporate Asset Schedule from live data, covering digital assets and fiat. The fiduciary reviews it and signs it as their own attestation.
Every sign-off timestamped
Data sources
Wallets, multisigs, custodians, exchanges and banks in one place. Keep the providers you already use; nothing needs to move. Every connection is read-only.

Structures and who can move them
Model structures as they exist legally, including companies, trusts and sub-funds. A trust is not owned by a company. For every asset line, the key-holder register shows who can move it.
Halyard Holdings (BVI) Ltd
BVI company · £790,000
Aldgate Reserved Powers Trust
Jersey trust · £12,904,118

Audit trail
Balances and sign-offs are timestamped and kept, with historic snapshots of the key-holder register.
Board reporting
Produce consistent board packs across all your structures, without rebuilding a spreadsheet each quarter.
Key-holder register
Who can move each line.
Lens keeps a key-holder register: the name, role and lines of each key holder, signatory and approver. It also keeps historic snapshots of that register.
It does not monitor key changes, check that people are still in place, or send alerts.

Client access
Give your clients a view of what is held for them.
Lens is for the fiduciary. If you choose, your clients can have their own view of the same records, provided through you.
Evoke Vault
For individuals and families
A view for high-net-worth clients of the holdings you hold for them, including the co-custody multisig where one is used.
Evoke Portal
For corporate structures
A read-only view for directors and stakeholders of what a company holds, and who can move it.
Vault and Portal are available only through a fiduciary using Lens.
03 · The Corporate Asset Schedule
What each structure holds, and who can move each holding.
For each structure, Lens prepares a Corporate Asset Schedule from live data. It covers digital assets and fiat. The fiduciary reviews it and signs it as their own attestation.
1
Point in time
The exact date, time and block height, so every figure can be reproduced later.
2
Holdings by asset line
Each asset, where it is held, its identifier, quantity, price source and value.
3
Control of every line
Who can move each asset, and under what rule, as recorded on the key-holder register.
4
Movements and exceptions
What changed in the recorded balances since the last schedule, and anything that did not reconcile.
5
Fiduciary attestation
The fiduciary reviews the schedule and signs it as their own attestation.
Lens keeps historic snapshots of the key-holder register. It does not monitor key changes or send alerts.

04 · Co-custody
Optional
Optional: Evoke as your recovery key.
Lens works with whatever custody you already use. Co-custody is a separate service for structures that want it: Evoke holds the recovery key in a Bitcoin multisig, while you and your client stay in control day to day.
Structure’s Bitcoin multisig
2-of-3
Key 1
You
The fiduciary. Signs day to day.
Key 2
Your client
Or their appointed representative. Signs day to day.
Key 3
Evoke
Recovery only. Never signs alone.
Any 2 of 3 to sign. Evoke can’t act alone.
When the recovery key is used
Day to day, you and your client sign. Evoke is not involved. Our key is used only to recover access, for example:
A key is lost, damaged or compromised.
A key holder is unavailable or can no longer act.
A director or representative changes and a key needs replacing.
Open standard, no lock-in
It is a standard, open Bitcoin multisig. You and your client hold two of the three keys, so funds stay spendable with or without Evoke, using any compatible wallet.
Connected to Lens
If you use it, that multisig appears in Lens alongside your other holdings, mapped to its structure. You never need co-custody to use Lens.
05 · Who it’s for
Built for people who are personally accountable.
For a regulated party responsible for digital assets it does not control, signing off on what it cannot easily see. The design-partner pilot since June 2026 is in Cayman, BVI, Jersey and Guernsey.
Independent directors
You sit on many boards and are accountable on each, often relying on someone else’s spreadsheet for what a structure holds.
Trust and corporate service providers
Structures with their own wallets, custodians and banks, and no single place to see them.
Fund administrators
Valuations and investor reporting that depend on reconciling on-chain, custodian and bank data by hand.
06 · Trust and security
Read-only by default
Lens connections can view balances only. They cannot move funds.
Your custody, your choice
Lens works with the custodians, exchanges, wallets, multisigs and banks a structure already uses.
