What stack do you build dApps on?

Typically Next.js or React with wagmi and viem for chain interaction, WalletConnect for wallets, and The Graph for indexing. For permissioned deployments we adapt the stack to the relevant SDK. We choose based on your team's existing skills where possible.

How do you handle a poor user experience around gas and pending transactions?

We surface gas estimates before signing, show clear pending and confirmation states, handle reverts gracefully, and can add ERC-4337 account abstraction so users transact without holding native gas tokens where it suits the product.

Can the dApp work with our existing back end?

Yes. Most production dApps are hybrid: on-chain for trust-critical state, off-chain for everything else. We integrate with your APIs, databases and auth so the blockchain layer is one part of a coherent system.

dApp engineering

Full decentralised applications: contracts, indexing and a wallet-connected front end that users trust.

We build complete decentralised applications, from the smart contract layer to a responsive front end wired up with wagmi, viem and WalletConnect. We handle event indexing with subgraphs or custom indexers, transaction state and error handling, and gas estimation so the user experience holds up under real network conditions. The result is a dApp that behaves predictably when transactions are pending, reverted or reorganised.

How we engage

A clear path from problem to outcome

Discovery and protocol selection

We map your use case, trust model and stakeholders, then choose the right chain and consensus: public EVM (Ethereum, Polygon, Base, Arbitrum), a permissioned ledger (Hyperledger Fabric, Quorum), or a Layer 2. We confirm whether a blockchain is actually warranted before any code is written.

Architecture and threat modelling

We design the on-chain and off-chain split, data and key-management model, gas and fee strategy, and upgrade path. Every contract is threat-modelled against known attack classes (reentrancy, access control, oracle manipulation) so security is built in, not bolted on.

Build, test and audit

We develop in Solidity, Vyper or chaincode with full unit, fork and invariant test coverage using Foundry or Hardhat. Contracts go through static analysis (Slither), fuzzing and an internal security review before any deployment to a public or production network.

Deploy, verify and operate

We deploy with reproducible scripts, verify source on the explorer, and hand over runbooks, monitoring and indexing (subgraphs, event listeners). Optional managed operations cover key rotation, upgrades and incident response after go-live.
