Custom Smart Contract Development Services
Security-first smart contracts for value-moving products, built for mainnet and auditsPixelPlex is a smart contract development company with 50+ contracts delivered and 1M+ successful on-chain executions across public and private chains. We write, test and audit the contract itself — Solidity, Plutus, Daml, Cadence — for DeFi logic, NFT mechanics, payments and KYC flows, then keep it upgradeable without breaking storage. Projects start at $20,000.
Challenges we solve
Worried a smart contract bug could get expensive?
We develop and test smart contracts around the potential risk points, combining solid test coverage with automated scanning and manual review to catch issues before deployment.
Tired of rebuilding the same NFT contracts?
Instead of starting from scratch every time, you get standards-based token and NFT contracts where minting and royalties are set up once, then tailored safely for each new launch.
Nervous proxies could break production?
Upgradeability is planned from the start, so storage layout and initialization rules don’t get missed. Then it’s validated through testing and an audit-style review to keep future changes controlled.
Price-feed dependency risks your DeFi logic?
Reliable oracle sources are selected early. From there, we code safeguards for delayed or unusual updates and test those cases before deployment, keeping the protocol steady when the market gets messy.
Getting crushed by slow execution on EVM chains?
We find the expensive parts first, then optimize storage and execution paths based on real usage. The updated contracts are re-tested so they run cheaper while the behavior stays consistent.
Multi-chain plans getting too messy?
From EVM networks to chains with different programming models, we help you make the right technical calls and adapt the implementation so the product stays consistent as chain details change.

Key benefits of smart contract development for your business
1.
Custom rules that run automatically
Turn repeatable processes into on-chain logic that executes once conditions are met. This reduces back-office effort and keeps the workflow consistent as volume grows.
2.
Lower friction in multi-party deals
Run agreements through a smart contract that enforces the rules once conditions are met. This reduces disputes because everyone can verify the same on-chain outcome, so partnerships move faster.
3.
New revenue models built into the product
Launch token and NFT mechanics that control access, distribution, or ownership directly on-chain. The rules live in the contract, so the business model stays enforceable as you scale.
4.
More predictable costs on-chain
Reduce cost spikes by optimizing storage and the most-used execution paths. This keeps everyday user actions affordable when usage climbs or network fees fluctuate.
5.
Safer launches with fewer expensive fixes
Validate contract behavior before release through strong testing and audit-style review. Catching issues early avoids rushed hotfixes and helps protect user trust after launch.

FAQ
How do you estimate cost and timeline?
Smart contract projects at PixelPlex start at $20,000, and the estimate is driven by four things: how complex the rules are, how much value the contract will control, what it has to integrate with, and how much testing, gas tuning and audit preparation the release needs. A small MVP is scoped in days. A contract that holds funds is scoped more slowly and in more detail, and you get a written scope before development starts.
When should a smart contract audit happen?
Schedule the full audit once the code is stable enough to review, which for most projects means close to mainnet, after core features are finished and only fixes are still landing. Lighter checks earlier in the build are still worth the time, because a design mistake found late is expensive to unwind. If the contract will hold funds or control valuable actions, treat the audit as a step in the release plan rather than a final formality.
How do you prevent exploits like reentrancy?
By relying on proven patterns for permissions and external calls, reviewing code against known failure modes, and writing tests that try to break assumptions instead of only confirming the happy path. Most exploits come from simple mistakes that surface only under real pressure, so the defense is deliberately boring. Across 450+ projects, PixelPlex has had 0 exploits since day 1.
Can upgradeable contracts still be safe?
Yes, provided upgrade powers are defined before launch, kept as narrow as possible and made transparent through clear rules. Upgradeability always adds one specific risk: someone is allowed to change the logic after deployment. That risk is managed by treating every upgrade as a real release, with the same testing and review the first deployment received, before anything touches mainnet.
How do you keep gas fees reasonable?
Gas cost is decided at design time rather than at the end, because some contract actions are expensive by nature and no amount of later optimization fixes an expensive architecture. During development, costly patterns are avoided, real transactions are simulated in testing to see what users would actually pay, and the most frequent actions are tuned first, since those dominate everyday cost.
Which blockchains do you build smart contracts for?
Ethereum and EVM chains, Solana, Polkadot, Cardano, Tron, BNB Smart Chain, Hyperledger Fabric, and Canton Network with Daml for confidential institutional workflows. The chain is chosen from what the contract has to do — throughput, fee profile, privacy requirements and settlement guarantees — rather than picked before the requirements are clear.
