Cold storage with qualified institutional custodians
Digital assets
Custody built for balances you cannot afford to lose
Custody is the part of crypto banking that nobody sees until it fails. Ours is deliberately boring: the majority of client assets stay offline, movements require multiple approvals, and the on-chain balances behind your statement are published so you can check them yourself.
Deposit addresses across Bitcoin and major EVM networks
Withdrawal whitelisting and address screening
Cold storage as the default, not the exception
Client digital assets are held predominantly in cold storage with qualified institutional custodians, using hardware-based key protection and multi-party computation so no single person or device can move funds alone.
A small operational float remains warm to settle same-day withdrawals. That float is monitored, capped and swept back to cold storage automatically once thresholds are reached.
Deposits across Bitcoin and the major EVM networks
Each client receives dedicated deposit addresses for Bitcoin and for Ethereum-compatible networks including Base, Arbitrum and Polygon, covering roughly 150 supported assets.
Deposits are tracked live through three stages — received, credited and swept — so you always know whether an incoming transfer has been confirmed on-chain, applied to your balance, or moved into deep storage.
Controls you can turn on yourself
Withdrawal address whitelisting, per-address cooling-off periods and step-up authentication are configurable from the client panel. Outgoing addresses are screened against sanctions and illicit-finance datasets before a transfer is released.
Holdings are reconciled against on-chain wallet balances continuously, and drift beyond a tight threshold raises an internal alert before it can reach a statement.
Getting started
How it works
- 01
Deposit
Send assets to your dedicated address on Bitcoin or a supported EVM network.
- 02
Confirm
Watch the deposit move from received to credited as the network confirms it.
- 03
Protect
Whitelist withdrawal addresses and set the approval rules for your account.
Questions
Crypto custody: common questions
- Who holds the private keys?
- Keys are held by qualified institutional custodians under hardware protection and multi-party computation, not by any individual at The Vision Bank. Transfers require multiple independent approvals and are checked against your account's withdrawal policy.
- How much is kept in cold storage?
- The large majority of client digital assets are held offline. Only a capped operational float is kept warm to service same-day withdrawals, and it is swept back to cold storage automatically when it exceeds its threshold.
- Can I verify the assets exist?
- Yes. Digital asset holdings are reconciled against on-chain wallet balances and covered by periodic proof-of-reserves attestations, which are published on the proof of reserves page.
- Which networks can I deposit on?
- Bitcoin plus the major EVM networks — Ethereum, Base, Arbitrum, Polygon and others — covering around 150 supported assets. Sending an asset on an unsupported network risks permanent loss, so the deposit screen names the exact network for each address.
