Real Projects for Real Clients
Fixed-scope pilots and production systems we've shipped for Krish Ventures, Aru Pharma, and NriHearts.com.
Finance OS — an Agentic Finance Department
An agentic system for Krish Ventures that automates end-to-end finance department operations — accounts payable and receivable, reconciliation, and reporting — with human-in-the-loop approvals.
Fully Local, On-Prem RAG System
A retrieval-augmented generation system for Aru Pharma that runs entirely on local machines — zero OpenAI or Anthropic API calls, and data never leaves the client's infrastructure.
HR Payroll System, Live in 1 Week
A payroll management system scoped, built, and shipped to production in one week — a fixed-scope AI MVP that went from idea to live product in days, not months.

Smart contract development at Essen Software is writing gas-optimized, auditable Solidity (or Rust for Solana) for tokens, protocols, and DeFi—on EVM chains (Ethereum, Arbitrum, Polygon) and beyond, with formal verification and audit coordination.
We support all EVM chains (Ethereum, Arbitrum, Polygon) and Rust-based chains like Solana. We choose the chain that fits your tokenomics, throughput, and cost requirements.
We use assembly-level optimizations and off-chain scaling to keep gas low. We partner with top auditors and ensure 100% bug remediation before mainnet launch.
Focused contracts (token, vesting, staking) run $5k–$15k fixed scope; protocol-level systems $15k–$50k+. Audit costs are quoted separately — we write contracts to pass audits the first time, which is usually the cheapest decision in the whole project.
Yes — our token contracts back a live 1:1 gold-backed platform (custody-verified supply) and a fractionalized real-estate platform, both with transfer restrictions and KYC gating. If your contracts need to represent real-world assets, see our RWA tokenization work.
