Platform overview

Paribu Custody is an institutional-grade custody infrastructure that ensures the secure, transparent, and compliant storage and management of digital assets. Developed by Turkiye’s leading digital asset platform Paribu, this infrastructure offers a secure digital asset custody experience for financial institutions, technology startups, and cryptocurrency actors.

This documentation is prepared for developers and institutional clients. It includes comprehensive information about the technical details of Paribu Custody APIs, integration steps, security policies, and usage scenarios. The goal is to enable institutions to integrate the Paribu Custody infrastructure into their systems quickly and securely.

What is Paribu Custody?

Paribu Custody is a flexible and scalable platform offering custody solutions for both current digital assets (cryptocurrencies, tokens) and real-world assets to be tokenized in the future (real estate, securities, artworks, etc.).

Key Features:

Advanced Asset Support: Compatibility with multiple blockchains and tokens (Ethereum, Bitcoin, Polygon, etc.)
Segmented Wallet Structure: Cold, warm, and hot wallet infrastructures providing operational flexibility
Institutional Authorization: Multi-signature structures and custom transaction policies
Regulatory Compliance: Full compliance with AML/KYC/Travel Rule standards

Security Architecture: ColdShield®

The security layer of Paribu Custody is built with a proprietary architecture called ColdShield®. ColdShield® brings together modern cryptography and physical security technologies to maximize the security of digital assets.

Core Components:

MPC (Multi-Party Computation): Keys are stored in multiple parts. Eliminates single key exposure.
HSM (Hardware Security Module): Hardware-based key storage and signing operations.
Intel SGX: Execution within a Trusted Execution Environment (TEE).
Admin Quorum: Transaction flows that require multi-authority approval (e.g., voting among managers for high-value transfers).
Policy: Enables institutions to define their own operational security policies (e.g., daily withdrawal limits, time-based restrictions, transaction type constraints). Every transaction is automatically evaluated according to defined rules and enters the approval process if necessary.
IP and Address Whitelisting: Asset transfers allowed only to pre-defined addresses.

This system architecture is designed and tested to include no single point of failure (SPOF).

API Usage and Integration

Paribu Custody APIs are designed based on RESTful principles. Integration is simplified using a JSON-based data format. The API endpoints cover the following operations that institutions may need:

Wallet Management: Creating new wallets, listing wallet addresses, tagging
Transaction Management: Deposits/withdrawals, transfers that require approval
Permission and Role Management: API key management, role-based access control
Asset Monitoring: Wallet balances, transaction history, blockchain activity
Staking and Delegation: Staking integration on supported networks (optional)

All API accesses are authorized using custom certificate signatures and access tokens. The developer documentation provides detailed sample requests, error codes, and information about the testing environment.
