Web3 Development Company

Web3 Services: reliable products built with trust and transparency.

In an industry often clouded by bad actors, we focus on integrity: secure code, clear scopes, and real-time progress visibility. We deliver across EVM and Solana — including audits (Rust + EVM) and custom bots — so you can launch faster with confidence.

What we build

End-to-end delivery for teams that need a dependable engineering partner.

Smart contracts

New builds, migrations, upgrades, and reviews. Clear invariants, tests, and deployment runbooks.

  • EVM: Solidity, Foundry/Hardhat
  • Upgradeable patterns + defenses
  • Gas profiling + monitoring

Audits (Rust + EVM)

Security reviews for production protocols — from quick assessments to full reports with fixes.

  • EVM audits: Solidity/Foundry, ERC20/721/1155, DeFi
  • Rust audits: Solana programs + off-chain services
  • Threat modeling, fuzzing, and remediation PRs

Bots & automation

Any type of bot: trading, alerts, moderation, support, and operations automation.

  • Telegram/Discord bots + dashboards
  • On-chain monitors, snipers, keepers
  • Backends: Node/Python + queues + hosting

Solana programs

High-performance programs and client tooling with a strong focus on correctness.

  • Anchor + native Rust
  • IDL-driven TypeScript clients
  • Compute/unit optimization

Web apps & SDKs

Frontends and SDKs your users trust—responsive, accessible, and production-ready.

  • Next.js/Vite, wagmi, viem
  • Solana wallet adapters
  • Typed APIs + docs

Security & reliability

Pragmatic security in every sprint: code review, test strategy, and incident playbooks.

  • Threat modeling
  • Fuzz/property testing
  • Observability + alerts

FAQ

Answers to the questions we get most often.

Do you do Solana audits?
We do engineering reviews, threat modeling, and test hardening for Solana programs; for formal audits we can partner with an auditing firm and support remediation.
Can you build both EVM and Solana in one project?
Yes—common patterns include bridging, shared off-chain indexing, unified frontends, and separate contract/program deployments with a single release process.
What do you deliver each milestone?
A PR, test results, a short demo, updated docs/runbooks, and a deployment plan. For Solana, we also include an IDL and client examples.
