How Skrumble scores platforms

Our principles

1. Receipts over vibes. Every claim ties to a tested transaction, a dated screenshot, or a primary-source citation.
2. Dated transparency. Every review carries a "last tested" date. Anything older than 6 months is flagged.
3. Affiliate-blind scoring. Commission rates have zero weight in our scoring. The order in which exchanges appear is determined by score, not by what they pay us.
4. Independent. No platform pre-approves what we publish. No paid placements. Read how we make money.

What we test

For every platform we publish a verdict on, we run a hands-on test. That includes:

• Account creation, KYC, and time-to-first-trade.
• A real deposit (typically the platform's minimum), priced and timed.
• A spot buy at a stated USD amount — actual cost vs market mid recorded.
• A withdrawal of the asset (when fees and timing permit) — actual fee and arrival time recorded.
• Customer support: at least one real ticket, time-to-first-response and time-to-resolution captured.

Scoring rubrics by platform type

Different platforms get different weights. We publish each rubric publicly:

• → How we score crypto exchanges

  5 pillars: Security & Trust (30%), Fees (25%), Asset Variety (20%), Ease of Use & Features (15%), Customer Support (10%).

• → How we score crypto bridges

  5 pillars: Security & Audits (35%), Transaction Speed (20%), Fees (20%), Chains & Tokens Coverage (15%), Reliability (10%).

When scores change

Scores are re-evaluated quarterly, or sooner when a platform publishes a material change (security incident, fee restructure, country restriction, regulatory action). Every score change is recorded with a date and a note of what triggered it.

What you can hold us to

Spotted a score that looks wrong, a number that doesn't match the platform's docs, or a fee we haven't updated? Tell us. Corrections get logged at the bottom of the affected review with a date.
