Crypto mining hosting contracts in 2026: what you're actually signing

Almost nobody publishes what a mining hosting contract actually says. Providers show you a per-kWh rate and a photo of a container in the snow. The clauses that decide whether you keep your machine when something goes wrong sit behind a "request a quote" form.

One real agreement is public, though. In September 2024, Stronghold Digital Mining filed its hosting agreement with Bitfarms as an exhibit to an SEC 8-K — 10,000 Antminer T21s, roughly 50 MW at Panther Creek, Pennsylvania. It is a negotiated contract between two listed companies, so the terms are better than anything a retail buyer will be offered. That makes it the right benchmark: if a counterparty with lawyers accepted these clauses, the ones in your click-through agreement are unlikely to be softer.

This guide walks through what that contract says, what the Compass and Core Scientific cases taught the market, and what to demand before you ship hardware to anyone. If you are still deciding whether to host at all, start with hosting versus mining at home; if you want rates, the 2026 hosting cost breakdown covers pricing.

The deposit is bigger than you think — and it should earn interest

Stronghold required a deposit of US$7,800,000. The contract doesn't state a round number; it states a formula: $70 per MW × 50 MW × 93 days × 24 hours. That is roughly three months of power, paid before a single machine is racked.

Two details matter more than the size:

• It is refundable within one business day of the term ending. Not "within 30 days of reconciliation" — one business day.
• It earns interest at SOFR + 1.00%, paid in kind. Your money is not sitting in the host's operating account for free.

Retail deposits are typically two to three months of power as well, which is proportionate. What retail buyers rarely get is the interest or the one-day refund deadline. Ask for both. A host that refuses to state a refund deadline in days is telling you something.

One more clause worth copying: the contract charges 24% annual default interest on the deposit. That cuts both ways, but it establishes the principle that late money costs money in both directions.

Who carries power-price risk — read this before the rate

The headline "$0.06/kWh" figure is the least important number in a hosting contract. What matters is who absorbs it when power costs more than that.

Stronghold's agreement is not a $/kWh deal at all. It is cost-plus with a profit share:

• "Agreement Cost of Power" = the host's actual fuel, O&M, G&A and financing costs × 110%, divided by MWh.
• The customer's share of profit is 50% of (mining revenue + power revenue − total cost).
• A fixed $210,000 per month upfront payment, trued up monthly.

Read that structure carefully. The customer carries 100% of power-price risk and guarantees the host a 10% margin on top of whatever power costs. If gas spikes, the customer pays. The host's margin is contractually protected; the customer's is not.

The three models you will encounter:

For a retail buyer with one to ten machines, all-in $/kWh is almost always the right structure. It is the only one where you can calculate your break-even in advance and hold the host to it. Competitive all-in retail rates sat around $0.065–$0.08/kWh in 2026; our own facility rates start at $0.014/kWh, which is what makes the maths on the profitability ranking work.

Curtailment: they can switch you off, and you may still pay

Stronghold may curtail for force majeure, maintenance, hazardous conditions — or simply "if [host] determines it is… more economical… to sell power to the grid." Written notice only. No consent required, no cap on hours.

That clause is standard and, in fairness, rational: during ERCOT's peak windows a Texas site can earn far more selling power back than mining with it. One Texas mining operation was paid over $31.7 million to curtail.

What is unusual about the Stronghold contract is that it compensates: "Power Revenue" from the curtailment sale is shared 50/50. But there is a sting in the definition — "Utilized MWh" includes curtailment electricity. The customer is charged cost-of-power on megawatt-hours it never consumed, then credited its half of the grid sale. Model the net, never the headline.

Retail contracts rarely share curtailment revenue at all. The question to put to any provider, in writing: "During curtailment, do I still pay the hosting fee, and do I receive any share of demand-response revenue?" We have not found a retail host that publishes an answer, which is itself informative.

What the contract disclaims — even after negotiation

This is the section that surprises people. In a negotiated agreement between two public companies:

• Services and facility are "AS IS" — no mechanical cooling, no backup power, non-redundant internet, no uptime warranty.
• No liability for lost revenue or profits during outages, curtailment or equipment failures — explicitly including pool operator failures.
• Total liability capped at $1,000,000 in direct damages, with no consequential or lost-profit damages at all, except for gross negligence or wilful misconduct.

Against a 50 MW deployment, a $1M cap is a token. And the host is not an insurer: the customer must carry insurance to full replacement cost, primary and non-contributory, naming the host as additional insured with waiver of subrogation.

The practical takeaway for a retail buyer: insure your own hardware. Do not assume the facility's policy covers your machine, because in every contract we have read, it does not.

If the host goes bankrupt, is the miner still yours?

This is the question that actually matters, and the answer depends on paperwork you control.

Three clauses in the Stronghold agreement do the work, and every one of them is worth demanding:

1. Identification. Every unit is labelled so ownership is identifiable. Serial numbers on the invoice and on a schedule to the contract.
2. Lien waiver. The host waives all distraint, levy, statutory liens and security interests in the miners. Without this, a landlord or lender may have a claim over hardware you paid for.
3. Non-fixture language. The miners are personal property and never become fixtures of the building.

The precedent everyone in this industry cites is Core Scientific's Chapter 11 in December 2022. The court permitted Core Scientific to reject Celsius Mining's hosting agreements covering roughly 37,536 machines. The rigs were shut down; the litigation eventually settled for $14 million. Hosted customers discovered that a hosting agreement is a contract the bankruptcy estate can walk away from.

Jurisdiction matters for the remedy:

• United States — file a UCC-1 financing statement. It is cheap and it puts the world on notice that the hardware is yours.
• United Kingdom — a bailee in possession owes a common-law duty of care; recovery runs through bailment and retention of title.
• EU — retention of title is preserved cross-border by Regulation 2015/848, Article 10. In Germany the mechanism is Aussonderung, and it works only if the goods are identifiable and unaltered — which is precisely why the serial-number schedule matters.

Getting your machine back

The Stronghold agreement gives the customer an Access Period of 90 days after default to remove equipment at its own cost — and critically, that period is tolled by any bankruptcy stay and resumes when the stay lifts. Copy that clause verbatim into any contract you sign. It is the difference between a claim and a forklift.

Miss the window and the host may run your miners and keep 100% of the proceeds. A voluntary swap-out needs 30 business days' notice, at the customer's sole cost.

Budget for the logistics. Indicative figures from hosting guides: $50–$200 per unit domestically, $200–$800 internationally, plus $0–$100 per unit for racking. We could not find a retail hosting contract that publishes per-unit de-rack and crating fees, so treat those as estimates and ask for the number in writing before you sign.

The Compass and Dynamics dispute — what it actually taught

The story is widely misremembered, so here it is precisely. In June 2022 Dynamics Mining terminated Compass's hosting deal in Maine over alleged non-payment; Compass denied it. Machines were withheld — The Block described it at the time as "hostage hardware."

The disputed numbers: Dynamics claimed $861,000 unpaid; Compass said it had paid $415,000 plus $250,000 in deposits against $1.2 million of power, plus $1 million in build-out loans. A court partly granted a restraining order, Compass retrieved the machines on 29 July 2022, refunded Maine deposits, issued facility credits, and later won $1.5 million.

Separately — and this is the part that matters for retail buyers — customers sued Compass itself for around $2 million over machines allegedly not returned.

The lesson is not "Compass bad." It is privity. Compass's customers had a contract with Compass. Compass had a contract with the site operator. When those two fell out, the end customers had no direct claim against the party physically holding their hardware. Before signing, ask: who owns the building, who holds the power contract, and am I contracting with them or with a reseller?

(A separate 2022 Compass event — two Georgia sites closing after a roughly 50% power-rate increase — is often merged with the Maine dispute. They are unrelated.)

Red flags in a hosting contract

• No named facility address or named operating entity.
• "Pass-through" pricing with an undefined cost base you cannot audit.
• Curtailment that is uncapped and uncompensated and still charges the rack fee.
• A deposit that is non-interest-bearing, or forfeited on exit.
• Auto-renewal with less than 60 days' notice.
• No serial-number schedule.
• Liability capped below one month's fees.
• No removal right that survives insolvency.
• Charges you cannot dispute after a very short window — Stronghold's is 15 days, and if you miss it you waive the claim.

What a fair 2026 contract looks like

A checklist to hand a provider:

• Named site, named entity, and a schedule of serial numbers.
• Deposit stated as a formula, interest-bearing, with a refund deadline expressed in days.
• All-in $/kWh, or a pass-through with an auditable cost base.
• Curtailment hours capped, with either a fee waiver or a share of demand-response revenue.
• At least 60 days' notice to exit; no evergreen auto-renewal.
• A 90-day removal right that expressly survives a bankruptcy stay.
• Explicit host lien waiver and non-fixture language.
• Retention of title (UK/EU) or a filed UCC-1 (US).
• Confirmation in writing of whether the hosting fee is suspended during downtime.

That last point is the single most valuable clause you can negotiate, and it is more useful than any uptime percentage. The Stronghold agreement contains a version of it: during suspended service the customer "shall not be liable or responsible for any obligations under this Agreement." Ask for the same. We cover why in the guide to hosted miner uptime and SLAs.

How we structure it

For transparency, since this article is on a hosting provider's site: you buy a specific, serial-numbered machine from us and own it outright. Hosting is billed at a transparent per-kWh rate from $0.014/kWh, deducted from mining earnings rather than invoiced up front. Coins are mined to your own pool account and wallet and never pass through us. You can have the machine shipped to you at any time.

We do not offer guaranteed returns, and nothing above should be read as a promise about profitability — see the live profitability ranking for current figures and the calculator to run your own.
