Overview
Most Web3 products fail on usability, not on cryptography. Users bounce at wallet connection, gas prompts and confusing transaction states. We build Web3 applications that feel like good software: embedded or smart-account wallets where appropriate, sponsored gas, clear transaction status, fast reads from an indexer instead of slow RPC calls, and a conventional backend for the things that should not live on-chain. Under that sits audit-ready contract code and the monitoring needed to run it.
Common use cases
- dApp for an existing protocolA fast, well-designed interface over contracts that already exist.
- Consumer Web3 productCollectibles, loyalty, gaming or community products with simple onboarding.
- On-chain finance appStaking, vaults, lending or payments with clear risk disclosure.
- Web2 to Web3 extensionAdding wallets, tokens or on-chain settlement to an existing product.
Quick answers
Web3 Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is Web3 development?
- Web3 application development — dApps, wallet onboarding, smart contracts and the off-chain backend that makes them fast and usable.
- Who is it for?
- Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
- What does Shivacha provide?
- dApp frontend
- Wallet onboarding
- Smart contracts
- Indexer & API
- Off-chain backend
- Launch & monitoring
- Which technologies are used?
- Next.js, Wagmi, Viem, Solidity, The Graph, Ethereum — chosen to fit your stack and constraints.
- How does the process work?
- Specify → Design → Implement → Test adversarially → Prepare for audit.
- What affects the cost?
- Contract complexity and number of chains
- Custody and wallet model
- Independent audit scope
- Indexing, analytics and back-office tooling
- Compliance integrations (KYC, AML, Travel Rule)
- Upgradeability and governance requirements
- How long does it take?
- A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.

Capabilities
What we deliver
dApp frontend
Next.js, wagmi and viem with robust transaction and error states.
Wallet onboarding
Browser wallets, embedded wallets, passkeys and account abstraction.
Smart contracts
Specified, tested and documented for independent audit.
Indexer & API
Subgraphs or custom indexers for fast, queryable on-chain data.
Off-chain backend
Auth, notifications, admin tools and integrations.
Launch & monitoring
Deployment scripts, contract monitoring and alerting.
Architecture
Engineered right from day one
The layers we typically design for smart contract engineering, adapted to your stack and partners.
- Audit-ready, not self-auditedInternal review supports but never replaces independent audits.
- Admin key designMultisig, timelocks and role separation for privileged functions.
- Upgradeability trade-offsProxies add flexibility and risk; used only when justified.
- Gas efficiencyOptimised where it matters, never at the expense of clarity or safety.
Delivery
How an engagement runs
- 1
Specify
Written specification with invariants, roles and failure modes.
- 2
Design
Contract architecture, storage layout, upgrade and admin model.
- 3
Implement
Minimal, readable code using well-reviewed libraries.
- 4
Test adversarially
Fuzzing, invariant tests, fork tests against real protocols and static analysis.
- 5
Prepare for audit
Documentation, coverage reports and a known-issues list for independent auditors.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Specification first
Roles, invariants and threat model documented before code.
Adversarial testing
Fuzz, invariant and fork tests plus static analysis on every change.
Key management
Admin keys in multisig or MPC with timelocks on sensitive actions.
Independent audit
Code prepared for — and we recommend — an external audit before mainnet value.

Frequently asked questions
What does Web3 development include?
Contracts, the dApp interface, wallet onboarding, an indexer or API for on-chain data, and the off-chain backend and admin tools. We scope only the layers your product needs.
Can users sign in without a crypto wallet?
Yes. Embedded wallets, passkeys and smart accounts let users start with an email or device login and move to self-custody later if they want to.
Which chains do you support?
Ethereum and EVM networks such as Polygon, Arbitrum, Optimism and Base, plus Solana.
What does audit-ready mean?
It means the contracts arrive at an independent audit with a clear specification, comprehensive tests including fuzz and invariant tests, static analysis resolved, documented trust assumptions and deployment plans — so auditors spend their time on deep issues.
Which languages do you use?
Solidity for EVM networks, with Vyper where appropriate, and Rust for Solana and other Rust-based environments.
