Contracts forged for mainnet reality
Zupitrix designs, writes, and hardens Solidity and Move contracts for DeFi, NFTs, DAOs, and enterprise chains — with gas budgets, upgrade paths, and audit-ready test suites owned from the first commit through mainnet delivery.

Capabilities
What Zupitrix forges on-chain
Continuous rails — not card grids — covering the full path from protocol design to mainnet ops.
Protocol engineering
Tokens, vaults, AMMs, staking, vesting, and governance modules built by Zupitrix from battle-tested patterns — not copy-paste templates.
Security & audits
Threat models, access control matrices, reentrancy guards, and CI static analysis so findings land before the auditor does.
Gas optimization
Storage packing, calldata discipline, and Foundry snapshots that keep user fees predictable under load.
Upgradeability
UUPS/transparent proxies, storage gaps, and timelocked admin flows when products must evolve without redeploying state.
Multi-chain deploys
Deterministic scripts, explorer verification, and shared ABIs across Ethereum L2s and compatible EVM networks.
Oracle & AA wiring
Chainlink feeds, VRF, and account-abstraction hooks integrated with clear failure modes and circuit breakers.
Audit posture
Bytecode that expects scrutiny
Zupitrix treats every public function as an attack surface. Invariants, fuzz campaigns, and peer review run in the same pipeline as deploys — so auditors inherit a living test suite instead of a black box.
- Invariant + fuzz suites in Foundry
- Slither gates on every pull request
- Remediation tracking through mainnet
Process
Five steps from threat model to mainnet
A vertical forge line that keeps architecture, tests, and ops in the same sequence — no handoff black holes.
Threat model & architecture
Zupitrix maps assets, roles, upgrade needs, and failure modes. Choose immutable vs proxy, oracle trust assumptions, and pause strategy before a line of Solidity lands.
Implementation & interfaces
Write modular contracts with NatSpec, OpenZeppelin primitives where they fit, and clean external ABIs for your dApp and indexers.
Tests, fuzz & gas reports
Unit, integration, and invariant tests; gas snapshots on hot paths; static analysis wired into CI so regressions never quietly ship.
Testnet & audit window
Deploy to public testnets, verify sources, run scenarios with your product team, and feed auditor findings into a tracked remediation backlog.
Mainnet forge & ops
Deterministic deploy scripts, explorer verification, ownership handoff, and runbooks for pauses, upgrades, and incident response.
Use cases
Protocols Zupitrix ships for
From DeFi vaults to enterprise RWA rails — same engineering discipline, different trust assumptions.
DeFi vaults & lending
Interest-bearing vaults, collateralized loans, and liquidation paths with oracle safeguards and liquidator incentives that hold under volatile markets — engineered end-to-end by Zupitrix.
NFT collections & marketplaces
ERC-721/1155 mints, royalties, allowlists, and marketplace settlement contracts with clear royalty enforcement and batch operations.
DAO & governance systems
Token-weighted voting, timelocks, treasury modules, and proposal execution that keep on-chain power checks readable to members.
Enterprise & RWA rails
Permissioned roles, compliance hooks, and upgradeable registries for real-world asset tokenization without sacrificing auditability.
Forge partnership
Protocol leads and Zupitrix in the same forge
We embed with your product and security stakeholders — shared repos, shared gas reports, and shared remediation trackers — so mainnet day is an ops event, not a surprise.
Stack & tooling
Tooling that compiles to confidence
Hardhat and Foundry for tests, OpenZeppelin for primitives, Chainlink for external truth — wired into CI by Zupitrix, not slideware.
Zupitrix writes production Solidity with NatSpec, modular inheritance, and explicit access control — never template dumps.
Mainnet-first design with L1 gas budgets, finality assumptions, and explorer verification baked into every deploy plan.
Price feeds, VRF, and Automation wired with stale-data guards and circuit breakers Zupitrix models up front.
Battle-tested primitives for tokens, access, and upgrades — composed carefully so storage layouts stay upgrade-safe.
Local networks, typed fixtures, and deploy scripts that mirror mainnet paths before any bytecode leaves the forge.
Foundry fuzz/invariant harnesses and Move-adjacent tooling when Aptos or Sui enter the architecture.
CLI helpers, chain tooling, and operational scripts that keep deploys and verifications reproducible.
Pinned toolchain images so CI, auditors, and your team compile the same artifacts every time.
PR gates for Slither, coverage, and gas diffs — Zupitrix treats the pipeline as part of the security surface.
L2 deploy configs, fee markets, and bridge-aware assumptions when your users live on cheaper rails.
Typed deploy, verify, and ops scripts that your frontend and indexers can trust as a single source of truth.
Content-addressed metadata and artifact pinning when NFT or RWA payloads must stay durable off-chain.
Zupitrix role
Your engineering partner for mainnet-grade contracts
Zupitrix is not a Solidity freelancing desk. We are the engineering partner that designs threat models, writes and peer-audits contracts, owns test suites and gas budgets, authors upgrade playbooks, and delivers verified mainnet deploys — from first architecture workshop to post-launch ops runbooks.
- Own threat models, role matrices, and upgrade vs immutable decisions before code
- Write, review, and harden contracts with Foundry/Hardhat suites Zupitrix maintains
- Set gas budgets, snapshot hot paths, and document every safety trade-off
- Ship upgrade playbooks, pause controls, and mainnet verification with handoff runbooks
