Smart contract audits

Blockchain development and smart contract audits you can take to mainnet

We design, build and audit smart contracts, dApps and tokenization on public and permissioned chains. Certified engineers review every line before deployment, so what goes on-chain holds up to real money and real attackers.

What we do

Blockchain Services, delivered end to end

The capabilities we bring to the table, named correctly and delivered by the people who do the work.

Smart contract development

Solidity contracts for Ethereum and EVM-compatible chains: tokens, vesting, staking, escrow and governance. Written for clarity, tested with Foundry or Hardhat, and gas-optimised.

Learn more

Smart contract security audits

Manual line-by-line review backed by static analysis (Slither) and fuzzing. We find reentrancy, access-control and solvency bugs before deployment and hand you a fix-verified report.

Learn more

dApp engineering

Full decentralized applications: on-chain contracts, an indexed backend and a Web3 front end with wallet connection (MetaMask, WalletConnect) that real users can actually operate.

Learn more

Tokenization and digital assets

ERC-20 tokens, ERC-721 and ERC-1155 NFTs, and real-world asset tokenization with supply, vesting and distribution logic that stays solvent under load.

Learn more

Permissioned enterprise chains

Private, permissioned ledgers on Hyperledger Fabric for consortiums that need shared records without a public chain: channels, chaincode and role-based access.

Learn more

Web3 integration with your stack

Connect on-chain logic to the systems you already run: payment rails, ERPs and databases, with off-chain services and oracles bridging the gap cleanly.

Learn more

Supply chain traceability

Tamper-evident provenance and tracking on-chain so partners share one verifiable record. Useful where audit trails and counterfeit resistance matter.

Learn more

Blockchain strategy and feasibility

An honest read on whether blockchain fits your problem, which chain model suits it, and what it costs to run. If a database is the right answer, we say so.

How we work

A method that turns scope into outcomes

A disciplined cycle, so you always know what is happening and what changes.

  • Certified practitioners
  • Outcomes backed by evidence
  • We build it, then support it
01

Feasibility and chain selection

We pressure-test the use case, decide public versus permissioned, and pick the chain and token model. You get a clear scope and an honest call on whether blockchain earns its place.

02

Design and contract architecture

We model the on-chain and off-chain split, design contract interfaces and data flow, and define the threat model up front so security is built in, not retrofitted.

03

Build, test and audit

We develop in Solidity or Fabric chaincode, write full test suites, then run a security audit with manual review, Slither and fuzzing. Fixes are verified before sign-off.

04

Deploy and support

We deploy to testnet, then mainnet, with monitoring and wallet integration in place. After launch we stay on for upgrades, re-audits and on-chain support.

Why NUEXUS

A partner that does the work and proves it

What sets our delivery apart in this domain.

We audit our own code

Security is not a bolt-on. Every contract goes through manual review plus Slither and fuzzing before mainnet, the same process we use on our own production token economics.

Public and permissioned, both

We work across Ethereum and EVM chains and permissioned Hyperledger Fabric, so we recommend the model that fits your case instead of forcing one stack.

Practitioners, not hype

We have shipped and audited contracts that hold real value. We tell you when blockchain is the wrong tool, before you spend on it.

Integrated, not isolated

On-chain logic is wired into the payments, data and systems you already run, with off-chain services and oracles so the blockchain part does not live on an island.
