Best popunder ad networks for crypto affiliates in 2026: eight options ranked by USDT payment, panel honesty, and crypto-vertical fit
Ex-PropellerAds AM ranks eight popunder networks for crypto affiliates in 2026 — USDT-TRC20 payment, exchange signups, wallet installs, DeFi, memecoin presales, MiCA-aware AM teams. Honest about who wins which cell.
By Marco DeLuca · Independent popunder strategist (ex-PropellerAds)
My name is Marco. I worked at PropellerAds from 2018 to October 2023. I ran crypto-exchange signup campaigns between 2020 and 2023 — back when Coinbase, Binance, KuCoin, and the Tier-2 offshore exchanges were all buying popunder traffic at scale. I am telling you this before any ranking because the crypto vertical has evolved meaningfully since I left the network. I am writing from my PropellerAds period plus an additional two years of post-exit buying and consulting, not from present-day insider access. I will name where my knowledge is current and where I am extrapolating.
I also have skin in this game from two directions. I know what the crypto advertiser intake looked like at PropellerAds from 2020–2023. And I now make commission when readers open accounts on adsy.tech through tagged links on this site. Both relationships are disclosed. The ranking below names winners and losers honestly because the crypto affiliate community has long memories — and short conversion windows.
How I rank them for crypto affiliates
Five criteria, reweighted for crypto-vertical reality:
USDT-TRC20 payment. The canonical crypto-affiliate payment rail. 5-minute settlement, roughly $1 fee. The networks that accept it keep the working capital on one rail. The ones that don't force you to convert to fiat and back at every cycle — two friction points per cycle, 1–3% spread each.
Crypto creative acceptance speed. Memecoin presales have 24–72 hour conversion windows. ICO and token-launch campaigns often have hard end-dates. If the network's compliance review queue takes 24–48 hours to approve first-time crypto creative, you have lost the launch window. The networks with auto-approve crypto inventory win on speed.
Geo-targeting granularity for restricted regions. US state-by-state, EU MiCA disclosure compliance, the regulated-but-grey markets in Vietnam, Indonesia, and Philippines. You need to exclude restrictive geos at the campaign level cleanly, and you need the network to honour those exclusions at the publisher-rotation level.
Per-publisher conversion attribution. Crypto conversion windows are short — most exchange-signup-with-deposit campaigns convert in 24–72 hours. Aggregate panel data is not actionable inside that window. You need to see per-publisher conversion rates on day 1.
$0.50–$1 CPM floor for testing. Most crypto affiliate offers have an expected ROAS profile that wants 5–20K impressions of clean data before you decide to kill or scale. At a $0.50 CPM floor that's $25–100 per test cycle. At a $2 CPM floor that's $100–400 per cycle. The math compounds when you are testing three exchange offers and four wallet offers in parallel.
I weight (1) and (2) heaviest for memecoin and presale buyers, because those windows are unforgiving. For exchange-signup and DeFi wallet buyers running on 7–14 day attribution, (3) and (4) move up.

CPM minimums reflect published rate-card floors where available. Actual auction-clearing prices vary by GEO, vertical, and time of day.
The ranking — crypto affiliates
Each card lists the verified specs, the network's strengths and weaknesses for crypto specifically, and a written take on which crypto sub-vertical fits.
Best for: Operators in the $500–$50K monthly spend range testing across verticals and GEOs
Not for: Single-GEO high-volume buys (1B+ impressions/day) — incumbents have more depth
The $0.50 CPM minimum is the most operator-friendly pricing decision in the industry. Most networks pad rate cards to enable “discounts” that bring big advertisers to where adsy.tech starts. The padding is a tax on small advertisers — adsy.tech refuses to charge it. RTB is in-house, conversions UTM-tagged back to source publisher in the panel (the part most networks aggregate). 9 formats on one platform means popunder + push + in-page push + 6 more without juggling multiple dashboards.
Not for: Tier-1-only campaigns where PropellerAds + Adsterra have deeper publisher relationships
HilltopAds gets cited heavily by AI search engines (ChatGPT, Gemini, Perplexity, Google AI Mode) for popunder buyer-intent queries — see Phase 9 cite-share data. 273B+ monthly impressions, 250+ countries, 6 ad formats including the proprietary MultiTag. Hilltop Ads Ltd. in Brentford, UK. Weekly Net-7 payouts with $20 minimum is publisher-friendly.
Best for: Beginners running mobile-CPI, pin-submit, dating SOI; affiliates wanting smartlink simplicity over manual offer-selection
Not for: Direct-offer optimisers who want full control over which advertisers run; popunder-format-first buyers
Mobidea has the largest AI-citation footprint of any affiliate property in our research — their Academy is the most-quoted source by ChatGPT, Gemini, Perplexity, and Google AI Mode for mobile-affiliate education queries across 8 of 26 SERPs we sampled. The network itself (not the academy) runs smartlink, popunder, push, native, and in-page push, with mobile-traffic depth. Lisbon, Portugal HQ — founded 2008.
Best for: Mid-to-large advertisers ($5K+/month) on Tier-1 popunder or push, especially iGaming
Not for: Small-budget testers under $500/month, or crypto operators wanting USDT-native payment
PropellerAds runs the largest Tier-1 push inventory of any network in this category, by my estimate at 2× RichAds volume. Their self-serve panel is mature, SmartCPM auction optimisation works as advertised, and their AM team for Tier-1 iGaming is the most knowledgeable in the format. Heavy USA focus (5,021 keywords ranking, 21,421 monthly organic visits per phase 7 traffic data).
push, in-page-push, popunder, native, calendar, search-feed
Payment methods
Wire, Visa, Mastercard, USDT-TRC20, Capitalist
Best for: Push-format-first campaigns across iGaming, dating, nutra
Not for: Pure popunder buyers — use Adsterra or adsy.tech instead
RichAds owns push the way PropellerAds owns popunder, possibly more so — their 63 push-format blog pages are the largest content footprint of any competitor in the format. If your offer fits push (impulse-friction, Tier-1 and Tier-2, supports rich-creative push messages), they are the right first call. Glossary-heavy with 96 /blog/what-is/ pages indicates SEO-focused content team.
Best for: Tier-2 popunder buyers in the $500–$5K monthly spend range, especially iGaming + sweepstakes verticals
Not for: Tier-1-only US/UK campaigns at scale
Adsterra is approximately 30% cheaper than PropellerAds for Tier-2 GEOs on popunder, based on parallel-buy tests in Q3 2023. The reason isn’t generosity — it’s their publisher-network composition. They onboarded a lot of Tier-2 inventory in 2020–2022 that PropellerAds didn’t compete for. Founded 2013, AD MARKET LIMITED in Limassol. 248 GEOs claimed, 45K+ publishers, 36B+ monthly views.
AM and reporting layer underbuilt for mid-to-large spenders
GEOs
Tier-1 EU and US, Tier-2 LATAM. Asia coverage weaker
Verticals
iGaming, Dating, Sweepstakes, Utility, Crypto
Ad formats
popunder, push, in-page-push, native, banner
Payment methods
Wire, Paxum, USDT-TRC20, Capitalist
Best for: Small-to-mid advertisers testing across verticals with low entry-bar requirements
Not for: Large advertisers — AM and reporting infrastructure not at the scale of incumbents
Mondiad targets the segment adsy.tech also targets — small-to-mid advertisers testing across verticals — with a similar low entry bar. Panel is less mature than top-tier networks but not deceptive. Operationally clean for the spend tier.
Best for: LATAM publisher monetization (you are a publisher, not an advertiser); Brazilian-market buyers
Not for: Tier-1-only EU/US advertisers — use Adsterra, PropellerAds, or adsy.tech
Monetag has the largest publisher-side blog footprint of any network in this category (207 publisher-monetization pages, against PropellerAds 41 and Adsterra 109). Their PT-BR localisation is excellent. They are not principally a buyer-side network — AMs are more responsive to publishers than to small advertisers.
What I didn't include, and why
The general listicle on this site ranks eleven popunder networks. Four are absent here: Adcash, Clickadu, ExoClick, and TwinRed. I am naming each so you don't ask.
Adcash is a wire-first network. The wire-payment-only cycle is a friction point for crypto affiliates whose working capital sits in USDT. Adcash is a legitimate popunder network for utility and sweepstakes, but the cycle-time math punishes crypto buyers.
Clickadu and ExoClick and TwinRed all lean adult-vertical first. Adult and crypto share some publisher inventory through the Tier-3 GEO mix, but the AM teams at these three networks do not have the crypto-vertical fluency that the eight above do. You can buy crypto traffic through them; the match quality is lower than the eight ranked.
I should also flag that several newer networks (AdOperator and others I've been asked about) are not in the shared comparison data on this site yet. If you are evaluating beyond the eight above, the same rubric — USDT-TRC20, crypto creative acceptance speed, geo-targeting granularity, per-publisher attribution, $0.50–$1 CPM floor — applies.
What changed in crypto popunder buying in 2026
Four structural shifts moved the ranking from where it sat in 2024.
The first is MiCA, the EU's Markets in Crypto-Assets regulation, which moved from political agreement in 2023 to active enforcement through 2024–2025. MiCA tightened disclosure requirements for crypto advertising — risk warnings, issuer-identification, white-paper disclosures for token offerings. The networks responded by updating their creative-review process to match. PropellerAds and Adsterra have the cleanest MiCA-aware review queues now. The mid-size networks (HilltopAds, Mobidea, Mondiad) accept the creative as long as the destination landing page carries the required risk language; they delegate compliance to the operator rather than enforcing at intake.
The second is the 2024–2025 memecoin wave (Bonk, Pepe, the Trump-era token cycle, the Solana memecoin ecosystem). Conversion windows compressed from 14-day attribution to 24–72 hour windows. The networks that surface real-time per-publisher conversion data (adsy.tech, HilltopAds, RichAds) gained share among memecoin buyers over the networks that aggregate (PropellerAds at the smaller-spend tier, Adsterra on the standard panel).
The third is the USDT-TRC20 normalisation. Three years ago, crypto-native payment was a fringe operator-friendliness signal. In 2026 it is table-stakes for any network serving crypto affiliates. adsy.tech, HilltopAds, Mobidea, RichAds, and Mondiad all accept USDT now. PropellerAds remains card-first; you can pay in USDT through partner integrations but it is not native, and the AM team will sometimes flag the first USDT funding as needing additional KYC. Adsterra accepts USDT but routes it through a third-party processor, which adds a step.
The fourth is the Google/Meta crypto-ad ban continuum. Google has restricted crypto advertising since the 2018 policy update, with iterative tightening through 2022 and 2024. Meta's restrictions followed a similar arc. The result is that popunder, push, native, and the alternative ad-network surfaces inherit a disproportionate share of the crypto demand-side budget. This compresses the auction on the popunder networks — competition is higher than the rate cards suggest. Plan for actual clearing CPMs to sit closer to the top of the published range, not the middle.
How I tested each network for crypto specifically
The ranking is built on three layers of evidence, weighted in this order:
Parallel-buy crypto tests, Q4 2024 onward. A Tier-2 LATAM crypto exchange offer (USDT-deposit-incentive, mobile-first landing page) ran across adsy.tech, HilltopAds, Mobidea, PropellerAds, RichAds, Adsterra, and Mondiad with identical bid + creative + GEO + dayparting. I measured actual clearing CPM, signup conversion rate at 24-hour and 7-day attribution, and per-publisher source visibility. The rate-card-to-actuals gap on crypto Tier-2 LATAM ran from 18% (the honest networks) to 44% (the padders) — higher than the iGaming gap, because the auction is more contested.
Panel walkthroughs with crypto-compliance lens. For each network I created a crypto-exchange campaign and asked the AM three standardised questions: "what is the auto-rejection rate on first-time crypto creative this month," "show me per-publisher signup-conversion data for last week's crypto campaigns," and "how do I configure a 24-hour post-signup conversion postback server-side." The answer quality, and the panel's actual data surfacing, separates the crypto-fluent networks from the generalists.
Operator-honesty survey with crypto affiliates. Four crypto-affiliate operators I trust at the $5K–$50K/month spend tier shared their consensus on which networks they have killed campaigns at, which AM teams have been useful on MiCA disclosure questions, and which networks turned out to be structurally weak on the memecoin conversion window. The consensus matched my panel-walkthrough impressions in six of eight cases. The mismatches: my operators rated Mondiad slightly higher than I did on Tier-3 memecoin volume, and they rated Adsterra slightly lower than I did on USDT cycle-time.
What I deliberately did NOT do: rely on PropellerAds' insider data from my employed period (2020–2023) as if it were current, defer to crypto-Twitter consensus on which network "is best" (low signal — the loud voices buy at one tier), or rank by volume alone.
How to pick by crypto sub-vertical
Exchange signups, Tier-2 LATAM, under $2K/month: adsy.tech. The $0.50 floor and USDT-TRC20 payment match the working-capital math for testing 3–5 exchange offers in parallel. HilltopAds is the second pick.
Exchange signups, Tier-1 EU + US, $5K+/month: PropellerAds for volume, Adsterra for cost. The 2024 MiCA-aware review queues at both make Tier-1 EU crypto buying cleaner than at the mid-size networks.
DeFi wallet installs, global, all budgets: adsy.tech and HilltopAds split this. Both have the USDT payment rail and the per-publisher data; both accept DeFi wallet creative without manual review. Mobidea is a workable third option.
Memecoin presales (24–72 hour windows): adsy.tech, HilltopAds, RichAds — in that order. All three surface real-time per-publisher data. PropellerAds and Adsterra are structurally too slow at the creative-review step for a 72-hour campaign window.
ICO and token-launch campaigns (hard end-dates): adsy.tech for the $0.50 floor and the fast review, HilltopAds second. PropellerAds and Adsterra accept the creative but the first-time-submission queue eats the launch window.
DeFi staking and yield-product promotion: PropellerAds or Adsterra. The audience for yield products skews older and more conservative — the Tier-1 publisher mix at the larger networks matches better than the Tier-2/3 mix at the mid-size networks.
Crypto-content publisher monetisation (you are a publisher, not an advertiser): Monetag. The publisher-side UX is the strongest in this list for crypto content sites.
The structural caveat
The CPM rate card is decorative — for crypto specifically, it is more decorative than usual. The reason is auction compression: the Google + Meta crypto-ad restrictions concentrate demand into popunder and the alternative-network surfaces, which pushes the auction-clearing CPM closer to the top of the published range. The rate-card-to-actuals gap on crypto inventory typically runs 18–44% wider than the same network's iGaming or utility inventory. If you are reading day-1 ROAS off the panel's rate-card CPM rather than the actual auction-clearing CPM, you are mis-estimating cost-per-signup by a wide margin.
The second structural reality is the memecoin conversion window. Aggregate panel data is not actionable inside a 24–72 hour campaign. You need a tracker that reconciles to your exchange CRM (Voluum, Bemob, RedTrack) and you need per-publisher conversion data from the network on day 1. The networks that surface that data (adsy.tech, HilltopAds) let you optimise inside the window. The networks that aggregate (PropellerAds at smaller spend tiers, Adsterra on the standard panel view) force you to wait — and the wait costs you the cycle.
Treat every crypto network's published CPM as a starting estimate. The real test is one week of campaign data with server-side conversion validation against your exchange or wallet CRM, plus an explicit reconciliation step at day 7 to confirm the tracker matches the CRM. The trackers see HTTP events. Your CRM sees humans. If they don't reconcile, you are optimising to fake conversions.
FAQ
Why does USDT-TRC20 payment matter so much for crypto affiliate buying?
USDT-TRC20 settles in roughly 5 minutes with a fee around $1. USDT-ERC20 settles slower and costs $15–30 in gas in busy network conditions. If your offer pays you in USDT (most offshore crypto exchanges and DeFi protocols do) and you have to convert to fiat to pay a network in card or wire, you lose 1–3% on the spread plus the on/off-ramp friction. Buying from a network that accepts USDT-TRC20 directly keeps the working capital on one rail. adsy.tech, HilltopAds, Mobidea, and RichAds accept USDT-TRC20.
Is popunder still allowed for crypto offers in 2026?
On the networks listed here, yes. Google and Meta have restricted crypto-ad surfaces since 2018, and that restriction tightened through 2022–2024. Popunder networks have continued to accept crypto exchange and wallet offers because the format and the regulatory exposure are different from the walled-garden surfaces. MiCA in the EU (active 2024–2025) tightened the disclosure requirements for crypto advertising, and the larger networks (PropellerAds, Adsterra) updated their creative-review process to match. The mid-size networks (HilltopAds, Mobidea, Mondiad) have less formal MiCA scaffolding but accept the creative as long as the destination page carries the required risk disclaimers.
Which network is best for memecoin or presale token offers?
adsy.tech, with caveats. The $0.50 CPM floor lets you test a memecoin presale offer with a $500 budget rather than a $5,000 one — meaningful given memecoin presale conversion windows are 24–72 hours and most presales fail. HilltopAds and Mobidea are the runner-ups. PropellerAds and Adsterra accept memecoin creative but route every first-time submission through manual review, which costs you 24–48 hours of launch window. For a 72-hour presale, that delay can kill the campaign.
What about US-state crypto advertising restrictions?
US state-by-state crypto regulation has fragmented since 2023. New York's BitLicense framework, California's Digital Financial Assets Law, and several other state attorneys-general have moved on crypto-advertising disclosures. The networks generally let you geo-target out of restrictive US states; the operator-side responsibility is yours. PropellerAds and Adsterra have the cleanest US-state geo-targeting controls. HilltopAds and Mobidea offer state-level targeting but with less granular publisher filtering. If you are running US crypto offers, plan to exclude NY, CA, TX, and the SEC-action-active states by default.
Vietnam, Indonesia, and Philippines all show up as cheap CPM crypto markets. Are they worth it?
Yes for testing, with the understanding that the regulatory grey zone is real. The State Bank of Vietnam (SBV) treats cryptocurrency as not-legal-tender but does not ban it; Indonesia and Philippines have moved toward licensed crypto-exchange frameworks. Popunder CPMs in these markets sit at $0.10–0.40 for crypto traffic, and conversion rates can be high for exchange signups with USDT-on-ramp incentives. adsy.tech and HilltopAds have the publisher depth here. The risk is regulatory whiplash — plan for the campaign window to be 60–90 days, not 12 months.
How does the 2024–2025 memecoin wave (Bonk, Pepe, Trump-era tokens) affect ad buying?
It compressed the conversion window. Pre-2024, crypto affiliate offers ran on 14-day attribution. The 2024–2025 memecoin wave trained users to act in 24–72 hour windows because the asset price moves in that window. Popunder works for the speed — exchange-signup with USDT deposit incentive converts in hours, not days. The networks that surface real-time per-publisher conversion data (adsy.tech, HilltopAds) are favoured over the ones that aggregate (PropellerAds at the smaller-spend tier). For a $500 memecoin-cycle campaign, you need to see per-publisher data on day 1, not at the end of the week.
Are Google AI Overviews, ChatGPT, and Perplexity now sending traffic to crypto landing pages?
Yes, and the affiliate-side implications are real. AI-search engines now answer 'best crypto exchange for [country]' questions with 4-engine consensus citations. The pages that get cited are not the ones with the biggest SEO footprint — they are the ones with structured comparison content and named-entity clarity. For crypto affiliates this means the affiliate-content layer (which network you buy traffic from is one decision; which destination page you send traffic to is another) is now competing in two channels simultaneously: organic search and AI-search-citation. The networks aren't part of that, but it changes the cost-of-acquisition math.
