CUSTODY AND WALLET INFRASTRUCTURE

Digital Asset Custody

The safekeeping and administration of digital assets—including private key management, transaction signing, and regulatory reporting—on behalf of institutional clients. It is widely regarded as the foundational control point for institutional participation in on-chain markets.

EXAMPLE

Northern Trust's digital asset custody service for tokenized fund shares handles key management, NAV reporting, and regulatory compliance in a single integrated platform.

Related Terms

Private Key

A secret cryptographic string that authorizes the signing of blockchain transactions and proves ownership of digital assets. Loss or theft of a private key results in permanent, irrecoverable loss of the associated assets.

Example

Institutional custody solutions abstract private key exposure through hardware security modules and multi-party computation, so no single operator can sign unilaterally.

Self-Custody

Direct control of private keys and digital assets by the asset owner, without delegating to a third-party custodian. For institutions, self-custody requires robust key management frameworks to meet regulatory and fiduciary standards.

Example

Anchorage Digital helps institutions implement qualified self-custody arrangements that satisfy OCC guidance without relying on a third-party custodian.

Wallet Infrastructure

The software, hardware, and operational systems through which institutions store cryptographic keys, sign transactions, manage access controls, and monitor digital asset holdings at scale.

Example

Copper.co's wallet infrastructure provides tiered access controls, transaction policy engines, and audit logs that integrate with a bank's existing compliance stack.

On-Chain Compliance

The embedding of regulatory requirements—KYC/AML checks, transfer restrictions, investor eligibility rules, and reporting obligations—directly into token logic or smart contracts, enabling automated enforcement at the point of transaction.

Example

Securitize embeds on-chain compliance into tokenized fund transfers so that accredited investor checks run automatically before any secondary market transaction settles.
