What We Build

Nine Areas of
Blockchain Expertise

DeFi
💱

DeFi Protocols

AMMs, lending platforms, yield aggregators, staking contracts, and liquidity pool architectures. We audit our own code before it touches a mainnet and design for economic attack surface, not just functional correctness.

NFT
🖼️

NFT & Digital Assets

ERC-721 / ERC-1155 collections, on-chain metadata, royalty enforcement (EIP-2981), marketplace contracts with bidding logic, and off-chain IPFS pinning pipelines that survive market cycles.

Infra
⛓️

Custom L1 / L2 Chains

Purpose-built blockchain networks using Cosmos SDK, Substrate, or OP Stack rollups. Validator set management, governance modules, tokenomics, and bridge infrastructure included.

Enterprise
🏢

Private / Permissioned Ledgers

Hyperledger Fabric and Besu solutions for supply chain provenance, trade finance, and regulated document workflows. We handle consortium governance, channel design, and integration with legacy ERP systems.

Contracts
📜

Smart Contract Systems

Proxy patterns (UUPS / Transparent), multi-sig governance, timelock controllers, upgradeable contract suites. Formal verification with Certora or Echidna for high-stakes deployments.

DAO
🗳️

DAO Infrastructure

Governor Bravo / OZ Governor with custom proposal types, quorum curves, delegation mechanics, treasury management via Safe, and off-chain signaling with Snapshot integration.

Identity
🪪

Decentralised Identity

W3C DID-compliant identity systems, verifiable credentials, EAS attestations, and ZK-based selective disclosure. Users own their data; you own the product experience.

Oracles
🔮

Oracle & Data Infrastructure

Chainlink custom feeds, push / pull oracle designs, MEV-resistant price aggregation, and cross-chain data bridges. On-chain computation stays trustless when the data source is verified off-chain.

Audit
🔍

Smart Contract Auditing

Manual line-by-line review, automated fuzzing with Echidna/Foundry, static analysis with Slither, economic attack modelling, and a written report with severity classification before every deployment.

Network Architecture

Designed for
Decentralisation

We architect networks with decentralisation as a constraint — not a goal. That means realistic validator economics, honest censorship-resistance trade-offs, and nodes that participants actually want to run.

Consensus Design
PoS, DPoS, PBFT, or Tendermint — chosen for your threat model

Smart Contracts

Code You Can
Stake Real Money On

Every contract we write starts from a battle-tested base — OpenZeppelin or ERC-standard foundation — then adds your business logic on top. Nothing custom where proven code exists. Everything audited before mainnet.

Multi-Sig Deployment
No contract goes to mainnet without 3-of-5 Gnosis Safe signatures from named keyholders. No single point of failure.
⏱️
Timelocked Upgrades
All upgradeable contracts require 48-hour timelock. Community can review and exit before any change takes effect.
🚨
Real-Time Alerting
Tenderly + custom webhook alerts on any unusual transaction pattern, abnormal TVL movement, or failed access control check.

Bug Bounty Ready
We help you launch a bug bounty on Immunefi post-audit — scope definition, payout structure, and triage workflow included.
Our Process

12 Weeks.
From Idea to Mainnet.

Week 1–2

Protocol Architecture

We map your tokenomics, governance model, and trust assumptions before writing a single line. You get a Technical Design Document with chain selection rationale and attack surface analysis.

📐
Week 3–4

Smart Contract Development

Core contract suite written in Solidity or Rust, using proxy patterns where upgradeability is needed. Every function has a matching unit test. Branch coverage target: 100%.

📜
Week 5–6

Testing & Fuzzing

Property-based fuzz testing with Echidna, invariant tests in Foundry, static analysis with Slither, and manual review of all privileged functions. We break it before anyone else can.

🧪
Week 7–8

Frontend & SDK Integration

Wallet connection (WalletConnect / Privy / Safe), transaction simulation, gas estimation UI, and event-driven state updates. The DApp feels responsive even on L1.

🖥️
Week 9–10

Testnet & Audit

Testnet deployment with load testing, economic attack simulation, and third-party audit by a named firm. We respond to all findings before mainnet consideration.

🔍
Week 11–12

Mainnet Launch & Monitoring

Multi-sig controlled deployment, on-chain governance parameter initialisation, Tenderly alerting, and a 30-day emergency response SLA for any post-launch incident.

🚀
Case Studies

Real Chains.
Real Industries.

Blockchain solves specific problems for specific industries. Here's how we've solved them across five verticals — each with different trust models, regulatory constraints, and performance requirements.

###
DeFi
Automated market maker protocol

A DeFi team needed a concentrated liquidity AMM — similar to Uniswap V3 — with custom fee tiers and a DAO-controlled fee switch. We built the core pool contracts, LP NFT positions, and a Foundry test suite with 100% branch coverage. Launched on Arbitrum with $40M TVL in week one.

Why Blenvo

What Sets Our
Blockchain Team Apart

🎯

Protocol-First Thinking

We design the incentive layer before writing code. Tokenomics, governance, and attack surface are documented in week one — not retrofitted after launch.

🔬

In-House Audit Capability

We run our own internal audit before any third-party review. Our engineers know how to break contracts — because they've built the ones that get broken.

⚡

Gas-Obsessed Engineers

Every function we write is profiled against gas costs. We know the EVM opcode pricing table and use assembly where the savings justify the complexity.

🌐

Cross-Chain by Default

We build bridges and messaging layers as standard features, not afterthoughts. Your protocol reaches users wherever they hold assets — without forking your codebase.
