A non-custodial wallet API lets businesses hold and manage crypto assets directly — without a third party holding funds on their behalf. Finrock provides a business-grade non-custodial wallet solution with team access controls, audit trails, compliance tooling, and payment workflow support.

Why businesses look for non-custodial wallet APIs

For many businesses, the appeal of non-custodial wallets comes down to two things: direct control and reduced counterparty risk. A non-custodial solution means the business holds the keys — not a third-party exchange or custody provider.

At the same time, self-custody has historically been difficult for teams to manage. Consumer wallets are not built for business operations — they lack multi-user support, access controls, audit logs, and integration with the kind of operational workflows a finance team or developer team needs.

What to look for in a non-custodial wallet API

A business-grade API should include:

  • Multi-user access with configurable permissions
  • Transaction approval workflows
  • AML screening on outbound and inbound activity
  • Audit logs and transaction history
  • Support for multiple wallets and asset types
  • Programmatic access via REST API
  • Integration with payment acceptance workflows

Finrock business use cases

  • Treasury teams holding and moving digital assets
  • Platforms issuing wallets or sub-wallets programmatically
  • Finance teams managing payout operations in crypto
  • Dev teams building payment or wallet flows on top of the API
  • Businesses wanting to combine wallet control with payment acceptance

Why this matters

The combination of self-custody with business controls is precisely what many teams need — especially those concerned about counterparty risk from custodians but also unable to use raw wallets for their operational needs. Finrock is designed to close that gap.
