Service · Web3 Wallet & Transaction UX

Web3 frontends users can trust with real money.

In Web3 the frontend is the custody interface: a misleading transaction state or a stale balance doesn’t create a support ticket, it loses someone’s assets. I’ve shipped production Web3 frontends across four products — a multichain wallet extension (CTRL, formerly XDEFI), a cross-chain DEX aggregator (Unizen), a wallet with marketplace features (OneArt), and Uniswap v4 analytics (HookRank) — and I build them the way that class of risk demands.

Sound familiar?

The situations this service exists for.

  • Your dApp works on the happy path but users get lost the moment a transaction is pending, dropped, or replaced
  • Wallet connectivity and multi-chain support keep breaking as chains and providers evolve
  • On-chain data in your UI is stale, inconsistent, or hammering RPC endpoints
  • You’re building a wallet or extension and need someone who has handled the security boundaries before

Scope

What the work covers.

  • Wallet browser extensions: architecture, signing flows, provider/page trust boundaries
  • Transaction UX as explicit state machines: pending, confirming, failed, replaced
  • Multi-chain wallet connectivity and swap flows across EVM chains
  • On-chain data layers: providers, subgraphs (The Graph), staleness handling
  • NFT product flows: minting, marketplaces, metadata
  • ethers.js / web3.js integration patterns that survive protocol churn

Outcomes

What you end up with.

  • Transaction flows where users always know what happened to their money
  • Wallet and extension surfaces built around the trust boundary, not around convenience
  • An on-chain data layer your UI can rely on without lying to users

Engagement formats

How to buy this.

Technical Strategy Session

60–90 minutes

A paid working session on one defined problem: an architecture choice, an AI feature plan, a performance question, a build-vs-buy call. You bring the context; I bring pattern recognition from 13+ years of shipping in situations like yours.

Product & Architecture Diagnostic

3–5 days

A focused investigation of one high-impact problem. I read the code, profile the system, interview the people closest to the pain, and separate symptoms from causes.

Start here →

Implementation or Rescue Sprint

2–4 weeks, fixed scope

I take hands-on ownership of the most critical part of the work — writing production code, making the blocking decisions, and coordinating with your product, design, and backend people until it ships.
