Key benefits
- Wallet onboarding that converts — WalletConnect plus embedded wallets with simulation previews.
- Reads, writes and events on separate, tested paths — no RPC polling in the render loop.
- Indexer-backed screens with sub-second loads and explicit loading, empty and failure states.
- Transaction-state machine covering simulation, signing, broadcast, confirmation and revert.
How we build dApps
A dApp fails where chains meet humans: signing, waiting and reverts. We start from the transaction lifecycle — what the user signs, what can fail, what they see while waiting — then work backwards into contracts and indexers. Frontend reads go through Wagmi and Viem with caching; history comes from subgraphs; live state arrives over websockets with reorg handling. Gas estimates are shown before signing, and every revert maps to human copy, not a hex dump.
For multi-chain products we add a deployment registry so one codebase addresses six networks, with chain-specific QA for finality windows and L2 sequencing delays.
What is included
- UX flows for connect, transact, track and recover paths
- React frontend with Wagmi, Viem and RainbowKit

Proof: multi-chain DeFi analytics
One portfolio across three chains — 1.8s loads, 41% fewer tickets.
Unified subgraphs with oracle pricing bands and reorg-safe sync.
Ethereum, Polygon, Base, Arbitrum, Optimism and Solana, with a deployment registry so one codebase covers all six.
WalletConnect for crypto-native users plus Privy embedded wallets for newcomers, with SIWE sessions and simulation previews.
Full dApps start from $24,000 / ₹19,90,000 for an 8–12 week build. Fixed scope follows a one-to-two-week architecture mapping.
