Blockchain Where It Actually Helps
We build smart contracts, token systems, and on-chain integrations for teams that need a real ledger — not a buzzword. Audited Solidity, gas-aware design, and the honesty to tell you when a Postgres table would do the job for one-thousandth of the cost. If your problem is multi-party trust, settlement, or provenance, we'll ship it. If it isn't, we'll say so.
You don't need a token.
You need a system that settles correctly.
Most blockchain projects fail twice. Once when they pick the wrong tool for the wrong problem, and again when an unaudited contract gets drained on launch day. We've cleaned up enough of those to be allergic to hype. We design for the boring outcomes: deterministic settlement, gas costs you can forecast, upgrade paths that don't require migrating users, and audits that catch the bug before the attacker does.
A contract you can't upgrade and can't fix
Deployed without a proxy pattern, no pause switch, no admin role, and now there's a bug. Your only option is to redeploy and ask 12,000 holders to migrate. They won't.
Gas costs nobody modeled
Every mint is $40. Every transfer is $12. The economics that worked on testnet collapse the moment you hit mainnet, and the product is dead before week two.
An audit that found the obvious and missed the real bug
Reentrancy guards everywhere, but the price oracle can be flash-loaned in one block. The auditor checked a list. Nobody thought like an attacker.
What You Actually Get
No vague deliverables. Here's exactly what lands in your hands.
Audited contracts on mainnet
Solidity or Rust, deployed to the chain that fits your problem. Verified source on the explorer, NatSpec docs, deployment scripts in your repo. Not a black box.
A full test suite + invariant fuzzing
Foundry or Hardhat, unit + integration + fork tests against real mainnet state. Echidna or Foundry invariants for the math you can't afford to get wrong.
A real audit, not a checkbox
We pair internal review with an external firm (Spearbit, Trail of Bits, OpenZeppelin, Cyfrin). You get the report, the fix PRs, and a re-audit before mainnet.
Keys, multisig, and ops in your name
Gnosis Safe under your control. Deployer keys handed over. Monitoring, alerting, and an incident runbook so you can pause, upgrade, or rotate without calling us at 3AM.
A Real On-Chain Engineering Team
Shipping a contract to mainnet without losing money takes more than one Solidity dev with a tutorial. Six roles you get on every Pillai Infotech blockchain build.
Senior Smart Contract Engineer
Solidity, Foundry, OpenZeppelin patterns, proxy upgradeability, EIP-2535 diamonds when justified. Has shipped to mainnet and watched the mempool the next morning.
Rust / Move Engineer
For Solana, Aptos, Sui, NEAR, CosmWasm. Knows when an alt-L1 actually fits the use case and when you should just use an EVM L2.
Security Reviewer
Reads code like an attacker. Reentrancy, oracle manipulation, MEV, signature replay, rounding bugs, access control. Runs Slither, Mythril, Echidna and reads the diffs by hand.
Tokenomics & Mechanism Designer
Models supply, emissions, incentives, vesting, governance — in a spreadsheet, against adversarial users. Catches the death spiral before it ships.
Off-Chain & Oracle Engineer
Indexers (The Graph, Ponder), keepers, Chainlink and Pyth integration, signed message flows, account abstraction. The bridge between web2 and the chain.
Ops & Incident Lead
Multisig flows, Tenderly alerts, Forta monitors, pause runbooks. The person who actually knows what to do when an exploit transaction lands in the mempool.
You See Everything. In Real Time.
Every Pillai Infotech project comes with a dedicated client dashboard. Kanban boards, live logs, test results, meeting notes — it's all visible the moment it happens. No status-report theatre, no "we'll get back to you", no surprises at the demo. You work with us like you work with your own team.
Kanban Board, Live
Every epic, every story, every task — visible on your dashboard. Drag, comment, reprioritize. It's the same board our team works from.
Documented Everything
Every decision, spec, API contract, and architecture diagram lives in the dashboard. Searchable, versioned, linked to the tasks they shaped.
Live Logs & Test Results
Build logs, deployment logs, test suite results — streamed to your dashboard the moment they run. You never have to ask "did the build pass?"
Meetings → Tasks, Automatically
Every meeting is recorded, transcribed, and every action point is auto-converted into a tracked task assigned to the right person. Nothing gets lost between calls.
Sprint Burndown & Velocity
See exactly how much work is done, how much remains, and our velocity over time. If a sprint is slipping, you see it the same moment we do.
Comment, Approve, Decide — In-Place
Comment on any task, approve designs, sign off on specs, and raise blockers directly in the dashboard. Everything tied to the work, not buried in email threads.
Blockchain Systems We Know How to Ship
We pick the chain and the architecture to match the problem, not a roadmap announcement.
🪙 Token launches done responsibly
ERC-20 / ERC-721 / ERC-1155, vesting contracts, merkle airdrops, sale mechanics. Audited, gas-optimized, with a kill switch and a cap table that matches the contract.
💱 DeFi primitives
Vaults, AMMs, lending, perps, restaking. Built with invariant testing, oracle hardening, and circuit breakers. We say no to designs that need a bull market to be solvent.
🏷️ NFT and digital ownership
Mints that don't melt under load, royalty enforcement where chains support it, on-chain or IPFS metadata, reveal flows, and a secondary-market story.
🔗 Supply-chain & provenance
Track-and-trace where multiple parties don't trust each other. On-chain anchors, off-chain detail, signed attestations. Real use case, not a press release.
🏦 Tokenized real-world assets
KYC-gated transfers, jurisdictional rules, custodian integration, redemption flows. Built with the regulator in the room from week one.
🗳️ On-chain governance & DAOs
Snapshot to on-chain execution, timelocks, multisig fallbacks, delegation, quorum design. Governance that survives a contested vote.
The On-Chain Stack We Use
EVM by default, alt-L1 when there's a real reason. We pick the boring tool when it's the right one.
Smart Contracts
Alt-L1
Security & Testing
Off-Chain & Infra
A Six-Stage Blockchain Delivery Process
Built around the reality that on mainnet, the bug ships before the fix.
Reality Check & Chain Selection
We start by asking whether you need a chain at all. If yes — which one, why, and what the trade-offs are. In writing, in week one, with a real cost model.
Spec & Threat Model
Every function, every role, every invariant written down. Threat model built before the first line of code: who attacks, how, what they gain, what stops them.
Build with Tests First
Foundry or Anchor tests written alongside the code. Fork tests against real mainnet state. Invariant fuzzing on the math. Coverage is a floor, not a ceiling.
Internal Review + External Audit
Internal security pass, then a top-tier external auditor. Findings fixed, re-audited, and published. We don't deploy until the report is clean.
Testnet → Mainnet Rollout
Testnet with real users, then mainnet behind caps and a pause switch. Multisig in your name. Monitoring live before the first transaction.
Post-Launch Watch
Forta alerts, Tenderly monitors, on-call rotation for the first 30 days. Incident runbook rehearsed. Hotfix or pause within minutes, not hours.
Three Ways to Engage
Blockchain projects don't fit one shape. Pick the one that matches your stage.
Reality Check Sprint
Two-week engagement to decide whether blockchain is the right tool, which chain fits, and what it actually costs. You leave with a written verdict and a plan B.
- Chain + architecture decision
- Tokenomics or mechanism review
- Honest yes/no in writing
Fixed-Scope Contract Build
End-to-end smart contract delivery, audited and deployed to mainnet, with off-chain integration and ops runbook.
- Fixed scope, fixed price
- Includes external audit
- 30-day post-launch warranty
Embedded Chain Squad
A dedicated contract + security + ops squad working alongside your team on a continuous protocol roadmap.
- Contract + sec + ops + PM
- Monthly retainer, scale up/down
- Best for: live protocols
Honest Answers to Blockchain Reality Questions
The questions every smart buyer asks before signing. Here's what we tell them.
Do we actually need a blockchain?
Probably not. The honest test: does your problem involve multiple parties who don't trust each other and need a shared, tamper-evident record? If yes, a chain helps. If you're using it for "transparency" or "decentralization" as a marketing line, a Postgres table with an audit log will be cheaper, faster, and easier to explain to your auditors. We'll tell you which one applies before we take your money.
Which chain should we use?
Default answer: an EVM L2 (Base, Arbitrum, Optimism) for most apps — cheap gas, mature tooling, real users. Solana when you need sub-second finality and high throughput. Aptos / Sui when the parallel-execution model genuinely fits. Bitcoin L2s only when the brand or settlement guarantee matters. We benchmark for your specific use case before recommending.
How much does an audit cost?
Real ones: $30k–$250k depending on scope and contract complexity. The $5k "audits" you see on Fiverr are checklists, not audits, and they will not save you. We bundle audit cost into fixed-scope projects so there's no nasty surprise at the end.
Should we make the contract upgradable?
Almost always yes, with a multisig + timelock. A non-upgradable contract sounds principled until the day you find a bug. We default to OpenZeppelin's transparent or UUPS proxy with a 48-hour timelock and clear admin roles, so you can fix things without nuking your users.
What about gas costs?
Modeled in week one, before code. We profile the hot paths in Foundry, set a per-transaction gas budget, and design the storage layout around it. If your design needs $40 mints to break even on L1, we move to an L2 or rethink the mechanism — not ship and pray.
Can you handle KYC and compliance for tokenized assets?
Yes. KYC-gated transfers (ERC-3643 / Polymath patterns), allowlists, jurisdictional rules, custodian integration. We work with your legal team and the regulator from week one — not after launch when it's too late.
What happens if the contract gets exploited?
On day one we set up: a pause switch, a multisig that can call it, Forta + Tenderly alerts on suspicious activity, and a rehearsed incident runbook. Across our last 40 deployments we've had zero exploits, but we plan for the day we do — because everyone eventually does.
Who holds the deployer keys and admin multisig?
You do. Gnosis Safe in your company's name, signers from your team, hardware wallets where the role matters. We'll be a co-signer during build if you want a second pair of eyes, but we step off the multisig at handover. No exceptions.
Can you integrate with our existing web2 backend?
Yes — most projects need this. Indexers feed your database, signed messages prove user intent, account abstraction hides the wallet UX from non-crypto users. We design the on-chain / off-chain boundary explicitly, so you know exactly what lives where and why.
Can you sign an NDA before we share details?
Always. NDA before the first call. Source, threat models, and audit reports stay under your control. We're happy to work inside your security tooling if compliance requires it.
