NASBIX TECHNOLOGIES

Smart contracts written for auditors and mainnet

Solidity on EVM—clear invariants, OpenZeppelin patterns, Hardhat or Foundry test suites, upgrade policy, and audit-ready documentation from our Karachi blockchain engineering team.

Smart contract development

On-chain code is expensive to fix—design and test accordingly

Smart contracts fail when roles are unclear, math is unchecked, or upgrades leave a single EOA in control. NASBIX delivers contract engineering as a discipline: written specs, explicit invariants, comprehensive tests, and deploy scripts your team and external auditors can follow without oral tradition.

We scope contract-only work or pair with dApp, DeFi, and NFT squads when you need the full product. Public-chain architecture and indexer needs tie back to blockchain development when the system spans on-chain and off-chain components.

Natspec, architecture diagrams, and role matrices before implementation spikes
Unit, integration, fuzz, and mainnet fork tests on critical paths
Upgradeability chosen deliberately—transparent proxy, UUPS, or immutable by design
Verified deploys, multisig handoff, and post-deploy monitoring hooks

Who we help

Built for teams that will be audited—or should be

Tokens, protocols, and enterprise pilots where bytecode carries financial or compliance weight.

Tokens & NFT contracts

ERC-20, ERC-721, and ERC-1155 with mint caps, roles, and royalty hooks defined in spec.

DeFi & protocol modules

Pools, vaults, staking, and governance contracts with economic assumptions documented.

Audit prep & remediation

Harden existing codebases, close findings, and expand coverage before mainnet or re-audit.

What you get

Smart contract capabilities that matter

Scoped to your chain, upgrade policy, and risk—not copy-pasted boilerplate without review.

Architecture & spec

Threat model, state machine, access control matrix, and explicit invariants auditors expect.

Solidity implementation

Readable modules, OpenZeppelin where appropriate, and custom logic where standards do not fit.

Testing & tooling

Hardhat or Foundry, coverage targets, fuzz campaigns, and fork tests against live protocols.

Upgrades & proxies

Storage layout discipline, initializer guards, and migration plans when versions must evolve.

Deploy & verify

Scripts for testnet/mainnet, explorer verification, and multisig-ready ownership transfer.

Audit package

Design docs, test reports, known issues list, and remediation tracking for third-party firms.

Security-first contracts

Depth that reduces exploit surface before TVL arrives

We treat reentrancy, oracle trust, centralization, and upgrade admin keys as first-class requirements—not audit surprises.

Checks-effects-interactions, pull payments, and reentrancy guards where applicable
Pausability and circuit breakers with documented activation roles
Integer and precision handling reviewed on financial paths
Static analysis (Slither, etc.) in CI with triaged findings
Coordination with external auditors and structured fix verification
Post-deploy monitoring recommendations and incident runbook templates
