04 / Web3

On-chain products built for the real world.

We build smart contracts, DApps, and blockchain-integrated products that are secure, gas-efficient, and ready for mainnet — not just a demo.

What's included

Smart contract development (Solidity / Rust)

Contract audit preparation + test coverage >95%

EVM-compatible chains: Ethereum, Polygon, Base, Arbitrum, Optimism

Solana programs (Rust + Anchor framework)

Web3 frontend: wagmi, viem, ethers.js

Wallet integration: MetaMask, WalletConnect, Coinbase Wallet

IPFS / Arweave for decentralised storage

Subgraph indexing (The Graph)

How it works

On-chain vs off-chain decisions, contract design, chain selection

TDD approach — tests written before implementation

DApp UI with full wallet flow and transaction feedback

Full end-to-end testing on public testnet, gas optimization pass

Staged rollout, monitoring, emergency pause mechanisms
