Blockchain development at Pharos Production: smart contracts, DeFi protocols, L1/L2 chains, dApps.
Blockchain development at Pharos Production: smart contracts, DeFi protocols, L1/L2 chains, dApps. Audit-first delivery with Foundry, Slither, OpenZeppelin and external auditors. 30+ projects shipped since 2018, zero critical vulnerabilities deployed.
Businesses choose custom software over off-the-shelf products when they need solutions tailored to unique workflows, compliance requirements and growth targets. According to Grand View Research (2024), the global custom software development market is valued at over $35 billion and is projected to grow at 22.3% CAGR through 2030. Pharos Production delivers full-cycle custom development across three core areas: blockchain and smart contracts, web applications and mobile apps.
We design and build custom blockchain networks and platforms with robust architecture, consensus mechanisms, and scalability. Our solutions support private, public, and hybrid models with full regulatory compliance for enterprise and startup needs.

Explore Cryptocurrency Wallet DevelopmentComprehensive cryptocurrency exchange platforms — CEX, DEX, or hybrid — with matching engines, liquidity aggregation, fiat rails, KYC/AML, advanced trading tools, and real-time monitoring.
Explore Cryptocurrency Exchange DevelopmentCustom blockchain development gives you full control over contract logic, gas optimization and security guarantees, while no-code chain platforms offer template contracts with limited customization. According to the 2024 a16z State of Crypto report, 78% of production DeFi protocols use custom-audited contracts because template contracts cannot be tuned for the specific economic attack surface.
| Factor | Custom blockchain build | No-code chain platform |
|---|---|---|
| Security | Threat-modeled, fuzz tested, externally audited; tailored to your attack surface | Generic security; shared template means shared vulnerabilities |
| Gas efficiency | Storage layout and calldata optimized; 30-70% gas savings vs templates | Generic storage; gas costs compound at scale |
| Multi-chain | Abstraction layer for 7+ EVM chains plus Solana; new chain in 1-2 weeks | Locked to vendor-supported chains |
| Upgradability | Proxy patterns + safe migration paths; tested rollback procedures | Limited to vendor upgrade roadmap |
| Token economics | Custom mint/burn/yield curves with formal verification of invariants | Pre-set economic models; cannot be tuned |
| Compliance | KYC/AML hooks, jurisdictional gating, audit trails baked in | Compliance is the customer's problem |
| Cost (year 1) | $25,000-$80,000 for smart contract suite + audit | $0-$5,000/month subscription + per-tx fees |
| Time to launch | 6-14 weeks for production-grade contract suite + audit | Days for a basic deployment; weeks to harden it |
Our blockchain practice ships production protocols, not testnets. PhD-led research on tokenomics and consensus design, a dedicated Solidity and Rust engineering team, Foundry-first test pipelines and 30+ on-chain projects delivered since 2018 across DeFi protocols, FinTech treasury and crypto rails, gaming, NFT marketplaces and supply-chain. We work the full stack: chain selection (L1 vs L2 vs app-chain, EVM vs non-EVM), token standards (ERC-20, ERC-721, ERC-1155, ERC-4626), upgradeability patterns (transparent proxy, UUPS, beacon), security architecture (multisig, timelock, pause-circuit-breaker) and post-mainnet monitoring (Tenderly, Forta, OpenZeppelin Defender). We do not deploy un-audited code to mainnet under any condition. Every project ships with Foundry test coverage, Slither and Mythril static analysis and external audit by Trail of Bits, OpenZeppelin or ConsenSys Diligence before mainnet cutover. We routinely advise clients to NOT use blockchain when a centralised database wins on cost, latency or compliance, and we say so before quoting. Below are selected blockchain projects from Web3 and crypto, FinTech and enterprise tokenisation clients.
Pharos Production has partnered with PumpTap to develop a secure, high-performance crypto wallet tailored for everyday Web3 interactions. PumpTap lets users store, send and manage digital assets across multiple blockchains through a simple, intuitive interface. Built on a scalable, event-driven architecture, the wallet delivers real-time transaction updates, robust security and seamless integration with decentralized applications.
Pharos Production partnered with Ludo to build a global cross-chain reputation system that makes trust transparent and portable across the Web3 ecosystem. Using AWS, Kubernetes, Istio, Kafka, Flink, Cassandra, Pinot and Solr, the platform processes blockchain data in real time to generate soulbound NFT-based reputation scores. With web, browser and Telegram interfaces, Ludo empowers users, curators and builders to identify trustworthy projects, integrate reputation APIs and strengthen community engagement. The result is a scalable, real-time trust layer that has been driving adoption in Web3 since 2021.

The Pharos Audit-First Pipeline is our four-step delivery cycle for production blockchain software: Chain-Fit, Threat Model, Audit-Gated Build and Mainnet Hardening. Chain-Fit (1-2 weeks) decides whether the problem actually needs a blockchain at all and which chain wins on cost, latency and tooling - L1 vs L2 vs app-chain, EVM vs non-EVM, Ethereum vs Polygon vs Arbitrum vs Solana - and the answer is sometimes "use a database" - artifacts: chain-fit memo, decline-or-proceed gate, target-chain selection. Threat Model (1-2 weeks) writes the spec and enumerates attack surfaces against the standard taxonomy: reentrancy, oracle manipulation, MEV, flash-loan, governance capture, upgrade-pattern abuse, signature replay, cross-chain bridge risk - artifacts: spec doc, threat model, invariant list. Audit-Gated Build (4-10 weeks) ships the contract suite under Foundry with invariant fuzz on every release branch, Slither and Mythril static analysis on every pull request and a 48-hour manual review pass before external audit submission - artifacts: test coverage report, static analysis report, gas profile. Mainnet Hardening (2-4 weeks) coordinates external audit by Trail of Bits, OpenZeppelin or ConsenSys Diligence, installs multisig, timelock and pause-circuit-breaker by default and ships a documented incident-response runbook - artifacts: external audit report, multisig + pause runbook, post-mainnet monitoring dashboard. The pipeline is named because mainnet deployment is irreversible - we re-enter Threat Model and Hardening on every upgrade, oracle change or new chain integration across the engagement lifetime.
Pharos Verified Delivery applied to 70+ production applications since 2013
Anonymized before/after snapshots from production projects. Metrics measured against client-reported pre-engagement baselines.
External audit queue time of 4-6 weeks. Each audit cost $25,000-$60,000. Critical vulnerabilities found in 3 of last 5 contracts during external review.
Automated pre-audit pipeline (Slither, Mythril, Foundry fuzzing) catches issues internally. 100% of Pharos contracts pass external audit on first pass. Zero critical vulnerabilities deployed since 2018.
We run <a href="https://github.com/crytic/slither" target="_blank" rel="noopener nofollow">Slither</a> and Mythril on every pull request, <a href="https://github.com/foundry-rs/foundry" target="_blank" rel="noopener nofollow">Foundry</a> invariant fuzz on every release branch and a manual review pass 48 hours before external audit submission. The last 5 external audits all returned zero-critical on first round.
Lending protocol cost $45-$120 per transaction in gas on Ethereum mainnet. Users abandoned the platform during peak gas periods.
Storage layout optimization, calldata compression and selective L2 deployment. Gas costs reduced 67%. Average transaction $15-$40. Daily active users grew 4x in 60 days.
Slot packing cut storage writes in half, calldata compression halved function selector overhead and the high-frequency borrow path moved to an L2 rollup with settlement back to mainnet. The rewrite shipped behind a feature flag with a 2-week migration window.
Single-chain wallet supporting only Ethereum. Custom bridge integrations took 8-12 weeks each. Users left for multi-chain alternatives.
Unified backend supporting 7+ EVM chains plus Solana. New chain integration in 1-2 weeks via abstraction layer. Wallet retention up 38%.
We built a chain abstraction layer that normalizes RPC calls, fee estimation, nonce handling and transaction signing across EVM chains and Solana. New chain support is now a config file plus a chain-specific adapter, not a rewrite.
Client names anonymized under NDA. Full case studies at /cases/.
We decline roughly 30% of RFPs we receive. Forcing a bad fit costs both sides 3-6 months and damages outcomes. Here is how we think about scope:
Not every problem benefits from decentralization. We start every blockchain engagement by asking "would a regular database solve this?" If yes, we say so. We have declined token launch projects where the product clearly did not need blockchain - because forcing it costs the client months and us our reputation.

External audits typically cost $25,000-$60,000 per contract suite from reputable firms (Trail of Bits, ConsenSys Diligence, OpenZeppelin). At Pharos we run an internal pre-audit pipeline (Slither, Mythril, Foundry fuzzing, manual review) so 100% of our contracts pass external audit on first pass, which avoids the typical 2-3 audit cycles and $50K+ in extra fees.
Production deployments on Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche, Solana and TON. We use a chain abstraction layer so multi-chain projects can ship a new chain integration in 1-2 weeks instead of 8-12.
We do not chain-shop; we recommend the chain that fits your gas budget, tooling needs and target users.
A production DeFi protocol typically takes 4-6 months: 2-4 weeks discovery + threat model, 8-12 weeks build with continuous fuzzing, 4-6 weeks external audit coordination and remediation, 2-4 weeks mainnet deployment with monitoring and runbooks. Pharos has shipped 100+ smart contracts since 2018 with zero critical vulnerabilities reported.
We build the smart contracts, deployment tooling and frontend for token launches. We do NOT provide securities-law advice; clients must engage qualified legal counsel on token classification (Howey test, MiCA, state-level rules) before mainnet launch.
We integrate KYC/AML providers (Sumsub, Onfido, Chainalysis) when the launch requires it.
Layered approach: storage layout optimization (slot packing, immutable for unchanging values), calldata compression, view-only state mirroring, batch operations where applicable, and selective L2 deployment for high-frequency paths. Real example: a lending protocol on Ethereum mainnet went from $45-$120 per transaction to $15-$40 after optimization, with daily active users growing 4x.
Yes. We offer Pharos security review covering Slither/Mythril static analysis, Foundry fuzz testing, manual review against the OWASP smart contract top-10 and a written report with severity ratings and remediation guidance.
This is not a substitute for an external audit by Trail of Bits, ConsenSys Diligence or OpenZeppelin, but it catches 80%+ of issues at 1/5 the cost.
We decline when: a centralized database would solve the problem faster and cheaper; the consumer product cannot tolerate wallet UX friction; the token launch lacks legal counsel on securities classification; or smart contracts handle regulated activities without a compliance plan. We have walked away from 30%+ of incoming blockchain RFPs for these reasons.
Solidity (with Vyper for security-critical contracts), Foundry as primary test/fuzz framework, Hardhat for tooling, OpenZeppelin contracts for standardized primitives, Slither and Mythril for static analysis, Echidna for property-based testing, Tenderly for monitoring. For Solana we use Anchor + Rust.
For non-EVM L2s we use chain-native toolchains.
