hazehire a dapp developer
the whole product, not just the contract: a fast next.js frontend, wallet connect that works on phones, contract calls that never confuse users, and a ui people enjoy.
what i build
- next.js + react apps with walletconnect / reown, wagmi and viem
- mint pages, staking dashboards, claim portals, token gating
- admin panels for your team: roles, pausing, treasury moves through a safe
- transaction flows with clear previews, gas estimates and failure messages
- indexers and apis behind the ui (ponder, postgres) so pages load instantly
- seo, analytics and share cards so the launch actually gets seen
why hire me
- one person for contract + frontend: no handoff gaps between two freelancers
- mobile wallets tested for real (the classic “connecting…” spinner fixed at the source)
- the free dev tools on hxxe.dev/tools are built on the same stack
- fixed scope and price, handed over with docs and deploy scripts
see the work: the free dev tools on this site are built and run by me.
how it works
- 01 · messagea few lines about what you’re building, your chain and your timeline.
- 02 · scopea short written scope with a fixed price and dates. no hourly surprises.
- 03 · shiptested code in your repo, deployed and verified, with docs. you own all of it.
pricing
a fixed price for a written scope, agreed before any work starts. small jobs are welcome, and if your budget is tight, i’ll tell you honestly what fits and what can wait for later.
questions
do you also do the design?
yes, a clean, modern ui is part of the build. if you have a designer or figma files, i implement them pixel-close.
will it work with mobile wallets?
yes: walletconnect with the right domain setup, deep links for wallet browsers, and tested on real phones.
where is it hosted?
usually vercel or cloudflare, on your account. you own the code, the domain and the deploys.
how much does it cost?
a fixed price, agreed before any work starts, based on a short written scope. small jobs are welcome: a single contract, a fix, a review of one file. tell me your budget and i’ll say honestly what fits in it.
how fast can you start?
usually within a few days. small scopes (a token, a fix, a review) often ship within a week; bigger builds get a timeline in the scope.
what do i get at the end?
the code in your repo, tests that pass in ci, deploy scripts, verified contracts and plain-english docs. you own everything and can run it without me.
how do we start?
send a few lines about what you’re building through the contact form or a dm on x (@0xHxxe). i reply with questions, then a scope with a fixed price and timeline.
