The Platform
Build product experience, not core custody infrastructure
Sends Hub is designed for teams that want to embed digital asset functionality into their applications without building the full operational backend themselves.
Developers can integrate wallets, transfers, and structured controls while maintaining ownership of the user experience.
What you can do
What technical teams care about
Four integration priorities that drive the design of every Sends Hub API endpoint and SDK method.
01
Fast integration paths
Ship wallet and transaction workflows without rebuilding infrastructure primitives.
02
Operational logic via API
Control wallets, permissions, and asset movement programmatically.
03
Security without friction
Support sensitive actions with stronger authentication and approval-based workflows.
04
Scalable architecture
Extend integration as product needs evolve from MVP to enterprise-grade operations.
API Capabilities
What you can build with Sends Hub
A unified set of endpoints covering the full operational stack of digital asset workflows.
Integration
Built for flexible implementation
Sends Hub fits into modern product stacks through a unified API model. Teams can integrate specific components based on their roadmap — whether they need wallet operations only, treasury logic, or broader governance-enabled transaction management.
REST API with JSON — framework agnostic
Webhook events for async workflows
SDKs available in JavaScript and Python
Sandbox environment — free to test
Who It's For
Designed for operational reliability
The platform is structured for business environments where wallet activity, permissions, and transaction controls must be reliable, auditable, and aligned with internal policies.
That makes it suitable for teams building products with real operational and financial consequences.
