Composable Infrastructure

Fully own the integration your customers build on

Flexible Primitives

Design your wallet integration with low-level components, free from provider roadmap constraints.

White-Labeled Integration

Build your own SDKs, APIs, and UI on top of Turnkey and swap infrastructure without disrupting customer integrations.

Delegated Access

Support custom automated signing flows from consumer apps to trading bots, with a single integration.

Security Controls

Built-in security guarantees every customer can trust

Tenant Isolation

Create dedicated end user environments for wallets, activities, and policies for fully separated integrations.

Co-Signing Authority

Require co-approvals on every fund-moving transaction, enforcing risk controls at the infrastructure layer.

Non-Custodial by Design

Enable end users to retain full control of their keys, allowing them to access funds or export wallets independently of your platform.

Case Studies

Halliday solves appchain fragmentation with Turnkey

Challenge

Halliday, an Intent Orchestration Protocol, needed wallet infrastructure that could handle the complexity of a multichain ecosystem at scale — so developers could abstract away fragmented onramps, wallets, and bridging from their end users.

Solution

Turnkey powers authentication and signing through an underlying multichain EOA signer. Together, Halliday and Turnkey give developers a seamless multichain stack without managing wallet infrastructure themselves. Learn more

Results

One-click transactions across multiple chains

Unified balance aggregation

Abstracted appchain complexity
