Cold Storage Archival API

overview

CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production at scale.

We architect and deploy custom smart contracts that power your core business logic. Our development process is built for security and maintainability from day one:

Full lifecycle development: From initial design and Solidity 0.8+ coding to deployment on EVM or Solana.
Security-first approach: All code follows OpenZeppelin standards and undergoes internal review before external audit.
Production-ready: Contracts include upgradeability patterns, gas optimization, and comprehensive testing suites.

Deliver a secure, audited MVP in as little as 2-4 weeks, not months.

We specialize in high-value contract types:

DeFi: DEX AMMs, lending/borrowing protocols, yield aggregators.
NFTs & Tokens: Custom ERC-20, ERC-721, and ERC-1155 implementations with advanced minting logic.
Utility: Multi-signature wallets, vesting schedules, DAO governance modules.

ENTERPRISE-GRADE DATA INFRASTRUCTURE

Core Capabilities of Our Archival API

Our Cold Storage Archival API delivers immutable, verifiable access to historical blockchain data, enabling secure analytics, compliance, and on-chain forensics without the operational overhead of running your own nodes.

Immutable Data Integrity

Access a cryptographically verifiable, tamper-proof ledger of historical blockchain states. Every data point is anchored to the canonical chain, ensuring audit trails for compliance and dispute resolution.

100%

Data Verifiability

Historical Reorgs

Multi-Chain Historical Indexing

Query full historical data—transactions, logs, internal calls, and state diffs—across EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Unified API schema simplifies cross-chain analysis.

PROVEN PROCESS

Our Delivery Methodology

We deliver enterprise-grade archival infrastructure through a structured, transparent process designed for security, reliability, and rapid integration.

Architecture & Security Review

We begin with a deep technical assessment of your data requirements and threat model. Our team designs a multi-layered security architecture using hardware security modules (HSMs) and air-gapped systems, ensuring your historical blockchain data is protected from genesis.

SOC 2 Type II

Compliance

Zero Trust

Architecture

Custom Indexing & Pipeline Build

We configure dedicated archival nodes for your target chains (Ethereum, Solana, Polygon, etc.) and build custom ETL pipelines. This ensures complete historical data capture, from genesis block to the latest state, with integrity verification at each step.

Frequently Asked Questions

Get clear answers about our secure, enterprise-grade archival solution for historical blockchain data.

Standard integration takes 1-2 weeks from contract signing to production deployment. This includes environment setup, custom index configuration, data backfill for your specified historical range, and final security review. Complex requirements, such as indexing custom smart contracts or multi-chain support, may extend this timeline.
