Bitcoin Institutional Custody Integration API

Secure, programmatic APIs for enterprises to integrate with institutional-grade Bitcoin custody solutions. We deliver multi-signature, HSM-backed transaction signing and treasury management systems.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts for tokens, DeFi protocols, and NFT ecosystems. Our development process includes formal verification and comprehensive unit testing to ensure security and reliability before mainnet deployment.

Deliver a battle-tested, gas-optimized contract suite in as little as 2-4 weeks.

Our expertise spans the full spectrum of standards and frameworks:

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • DeFi Primitives: Automated Market Makers (AMMs), liquidity pools, staking, and vesting contracts.
  • Security First: Built with Solidity 0.8+ and audited OpenZeppelin libraries, following best practices to mitigate reentrancy and overflow risks.

Business Outcomes for Your Treasury Operations

Our Bitcoin Institutional Custody API delivers measurable improvements to your treasury's security, efficiency, and compliance posture. Move beyond basic wallet management to a fully integrated, institutional-grade financial system.

01

Enhanced Security & Risk Mitigation

Multi-signature MPC wallets with geographically distributed key shards eliminate single points of failure. All operations are protected by hardware security modules (HSMs) and SOC 2 Type II compliant infrastructure.

Client Value: Eliminate counterparty risk and protect assets from internal/external threats with bank-grade security controls.

PREDICTABLE, TRANSPARENT, AND LOW-RISK

Our 4-Phase Delivery Methodology

We de-risk institutional Bitcoin custody integration with a structured, milestone-driven process. Each phase delivers tangible value and clear go/no-go decision points, ensuring alignment and predictable outcomes for your team.

01

Phase 1: Architecture & Security Review

We conduct a deep-dive analysis of your current tech stack and compliance requirements. Deliverables include a detailed threat model, a multi-signature key management architecture, and a formal security audit plan. This phase establishes the technical and regulatory foundation for a secure integration.

Frequently Asked Questions

Common questions from CTOs and compliance officers evaluating institutional-grade custody solutions.

Typical integration for a standard multi-signature vault is 2-3 weeks from contract signing to production deployment. This includes environment setup, key ceremony, policy configuration, and end-to-end testing. Complex setups with custom transaction policies or regulatory reporting may extend to 4-5 weeks.
