About signin

signin launched in 2021 with a single goal: build a secure crypto exchange that charges fair fees and actually explains what it's doing — no fine print burying the real costs.

Our Mission

Crypto exchanges have a trust problem. Fees hide in obscure tier tables, security incidents get buried in PR statements, and beginners get zero guidance. signin was built to fix all three.

Every policy, fee schedule, and security audit result is published publicly. If you can't find something in under 30 seconds, we consider that a failure on our part.

What We Built

A regulated spot exchange covering 300+ trading pairs, with a matching engine clocking sub-50ms execution times. The infrastructure runs across three geographically separate data centers.

98% of user funds stay in air-gapped cold storage at all times. The remaining 2% in hot wallets are covered by a $50 million insurance policy, renewed annually.

Our Team

The team behind signin includes former engineers from major financial institutions and security researchers with backgrounds in cryptographic protocol design. 60+ full-time staff across engineering, compliance, and support.

Regulation & Compliance

signin operates under financial services licenses in the EU and multiple jurisdictions. SOC 2 Type II certification was completed in Q1 2026 following an independent third-party audit.

KYC and AML processes meet FATF standards. All user data handling complies with applicable data protection regulations, including GDPR for European users.

Fees & Transparency

The base trading fee is 0.1% — flat, with no hidden spreads added on top. Volume-based discounts are calculated automatically and applied in real time. The full fee schedule is always visible before you place an order.

Security Track Record

Since launch in 2021, signin has processed over 28 million trades without a single security incident affecting user funds. Annual penetration tests are conducted by external security firms.

Bug bounty reports are reviewed within 48 hours. Critical vulnerabilities receive a reward of up to $50,000. The full bounty program terms are published on the platform.

Growth & Milestones

2.4 million trades are executed monthly on signin as of 2026. The platform has grown from 12,000 registered users at launch to over 800,000 verified accounts — without a single aggressive growth campaign.
