SizeProp Review

A Multi-Asset Crypto Prop Firm Backed by Igloo Inc. - The company behind Pudgy Penguins

Important Context: SizeProp Is Not an Onchain Prop Firm

We're upfront about this because it's the first thing a serious trader should know: SizeProp trades on simulated capital, not live onchain positions, and its evaluation rules aren't enforced by smart contracts. That's why it sits in our Crypto Prop Firms section rather than alongside the Hyperliquid-native firms in the main Onchain Prop Firms table. If what you want is verifiable, contract-enforced execution, look at the onchain-native firms in the main directory instead.

What SizeProp does offer is a crypto-denominated payout — funded profits are paid out in stablecoins — and multi-asset market access that most onchain-only firms can't match, since they're generally limited to whatever a single DEX lists.

Three Evaluation Types, One Simple Idea: Pick Your Risk Profile

SizeProp runs three evaluation structures, and the differences are entirely about how much room you get versus how fast you can pass.

Degen is the cheapest and fastest path, but the tightest: an 8% target against a 3% max drawdown gives roughly a 0.4x cushion — thin margin for error, built for traders confident in a tight setup. 1-Step widens that room to a 5% max drawdown against a 10% target, a more balanced ratio for traders who want a single evaluation without Degen's razor-thin risk allowance. 2-Step is the most forgiving on a per-phase basis — a 5% Phase 1 target is easy to clear — but resets you back to the starting balance for a second 10% push, trading speed for a larger overall cushion (6% max drawdown).

All three share the same baseline: no minimum trading days, no time limit to complete the evaluation, and no consistency rule. The daily loss limit recalculates every day at 8:00 PM UTC based on that day's balance; the max drawdown is static and fixed from your starting balance for the life of the evaluation. The one activity requirement across the board: place at least one trade every 90 days, or the account goes inactive.

Rule Breaches Are Automatic and Final

If your equity touches either the daily loss limit or the max drawdown, SizeProp terminates the account immediately — positions close, access is revoked, and there's no refund. There's no appeals process beyond flagging a suspected technical error; automated breach determinations stand. This is standard across the prop firm industry, but worth stating plainly: the drawdown numbers above aren't guidelines, they're hard stops enforced in real time on equity, not just closed balance.

What You Can and Can't Do

SizeProp's rulebook is closer to a traditional multi-asset prop firm than a DeFi-native one, which shows up most in what it explicitly permits: scalping, day trading, swing trading, and news trading are all fine. So is holding positions overnight or over the weekend, using stop losses and take profits, and layering or dollar-cost-averaging into a position. Hedging is allowed, but only within a single account — you cannot hedge across multiple accounts you control.

The prohibited list is aimed squarely at pass-farming behavior: high-frequency trading and tick scalping, exploiting platform errors or execution latency, arbitrage between accounts, copy trading or trade replication, account sharing or third-party trading, off-the-shelf bots or scripts marketed specifically to pass evaluations, spoofing, and coordinating multiple simultaneous evaluations to hedge risk. SizeProp also caps you to one paid account active at a time — you can't run a second evaluation while another evaluation or funded account is live, which rules out the multi-account farming strategies some traders lean on elsewhere.

Passing the Evaluation: What Changes

Once you hit the profit target with all positions closed and no rule violations, you're eligible for a funded account after completing KYC. One detail worth flagging clearly: the funded account starts from your original starting balance, not your ending evaluation balance. If you cleared your 1-Step evaluation with $112,000 on a $100,000 account, your funded account still starts at $100,000 — the overshoot doesn't carry over as extra buffer.

Funded Account Rules and Profit Split

Funded accounts carry no consistency requirements — no minimum trading days, no cap on how much profit comes from a single day, no requirement to distribute profits evenly across sessions. That's a meaningfully looser funded-stage ruleset than firms that impose a "no single day above X% of total profit" rule.

You choose your profit split — 80% (default), 90%, or 95% — at the time you purchase the evaluation, and it's locked in from that point forward; there's no upgrading the split after the fact. The max drawdown on a funded account stays fixed to your starting balance and doesn't move. The daily loss limit, however, is reduced by the amount of any payout you take, recalculating at the next 8:00 PM UTC reset — a mechanic worth understanding before you request a large payout mid-week, since it tightens your daily room afterward.

Payouts

Payouts are paid exclusively in stablecoins on Ethereum mainnet to a wallet address you provide — no bank transfers. The minimum payout is $50. SizeProp's marketing states payouts land within 24 hours of approval; its help documentation adds that requests go through a review step first, and the transfer is processed immediately once that review clears (occasionally with additional verification). Treat "within 24h" as the target, not a contractual SLA, until a public payout track record builds up.

Payouts are settled in stablecoins, but SizeProp doesn't publicly disclose payout data in order to protect trader privacy — that's why we mark Payouts Verified: No in our comparison table and don't track payout data for this firm.

Pricing

Evaluation pricing scales with account size and evaluation type. As two data points from the site: a Degen $100,000 evaluation runs $522 with the IGLOO discount code applied (10% off), and a 1-Step evaluation was listed at $899, down from a $999 list price (account size not specified for that listing). Pricing is subject to change and varies by account size — check current pricing on-site before purchasing, and apply the IGLOO code at checkout if it's still live.

What Gives Us Pause

Two things. First, "not onchain" means you're trusting SizeProp's internal systems the same way you'd trust any traditional prop firm — there's no smart-contract-enforced evaluation logic or onchain-verifiable payout trail the way there is for firms like Hypernova or Carrot Funding. Second, the platform is young enough that community payout history is still thin; the Igloo Inc backing is a real credibility signal, but it's not yet the same as a long public track record of on-time payouts at scale.

The Verdict

SizeProp's pitch is genuinely different from the rest of this directory: one account, 150+ instruments across crypto, equities, forex, and commodities, three evaluation structures to match your risk appetite, and a split that goes as high as 95% if you pay for it upfront. The Igloo Inc backing — a company that has actually shipped a consumer brand at retail scale — is a more substantive credibility signal than most "backed by" claims in this space.

Our recommendation: if multi-asset exposure matters more to you than onchain-verifiable execution, SizeProp is one of the more credible newer entrants to try. If onchain enforcement and verifiable payouts are non-negotiable for you, stick with the firms in our main Onchain Prop Firms table and revisit SizeProp once its payout track record matures.
