Managed blockchain infrastructure
HM Web3 builds and runs the on-chain infrastructure your product needs: smart contracts, wallet integrations, monitoring, custom-built for how you work, managed by us, deployed under your own keys.
~80%
of exploited protocols in past years had no ongoing monitoring in place; the bug existed for months before anyone noticed.

unaudited deploy is often all it takes. Most incidents trace back to a single unreviewed contract change.
£0
is what a frozen contract shows up as in your books until users notice. That's the problem: the risk is invisible until it isn't.
We build, audit, and monitor your smart contracts, wallet integrations and on-chain infrastructure, then keep them running for you.
Custom contracts written and tested for your use case: tokens, vesting, marketplaces, DAOs. Not a forked template with your logo on it.
Every contract is reviewed line by line before it touches mainnet. Findings are triaged and fixed, not just listed in a PDF nobody reads.
Connect your product to the chains and wallets your users actually have, with clear error states when a signature fails or a chain is congested.
Contract events, balances, and anomalies are watched around the clock, with alerts routed to you before a small issue becomes an exploit.
A plain-English weekly summary: transactions processed, gas spent, anything flagged. No block explorer required.
Tap one block from each row - what’s live, what’s worrying you, and what you want done about it. Thirty seconds, no wrong answers, and the 15-minute call starts with a risk map instead of a blank page.

That’s plenty for one call - send them over.
That’s the shape. Send it over and we’ll arrive with a plan for exactly this.
That’s fine - most people aren’t.
Mapping where the risk actually sits is exactly what the free call is for. But even a rough sketch doubles what we can cover in fifteen minutes: pick whichever blocks feel closest and we’ll refine them together on the call. There’s no wrong answer.
A 15-minute call, then we map your existing contracts and infrastructure and where the risk actually sits. You get the findings whether or not you hire us.
We design and build around your existing stack, no rip-and-replace, on infrastructure that belongs to your business, audited before it ships.
We monitor, maintain, and improve it continuously. When something on-chain moves at 7am on a Saturday, we usually know before you do.
Most shops ship a contract, invoice, and vanish. Six months later an upstream dependency breaks silently and nobody notices until funds are stuck. We run what we build: monitoring, upgrades, and fixes are the service, not an extra.
Your contracts and infrastructure are deployed under your control, not a shared deployer key we could hold hostage. If we ever part ways, the system and its keys stay yours.
No forked templates squeezed onto your workflow. We build around how your product actually works: your chains, your tokens, your process.
Every project is different. We scope it before we price it.
We learn what you are building, the chain and integrations involved, and the level of ongoing support it needs. Then we send a written proposal with the deliverables, costs, and next steps clear before you decide. No hourly billing or surprise extras.
Book a 15-minute callNo. We build around the chains and tools you already use. If you have gaps, we'll recommend simple options, but replacing your stack is never a requirement.
We monitor your contracts and infrastructure around the clock, apply upgrades, fix anything that breaks, and make ongoing improvements. You never file a ticket with a faceless vendor; you message us.
Most audits complete within 2 to 3 weeks of kickoff, depending on contract complexity.
Your contracts and infrastructure were deployed under your own keys, so they stay with you. We hand over documentation and access, no hostage-taking.
Yes. EVM chains by default, with support for others by arrangement. We'll tell you upfront if a chain is outside what we can responsibly support.
The smaller the team, the more a single exploit or bad deploy costs, because there's no slack to catch it manually. Our entry engagements are scoped for small product teams.
