Why Top One

Investing finally caught up to your phone.

Every part of the experience - onboarding, funding, trading, withdrawing - was rebuilt for a screen you hold in one hand.

Real-time markets

Finnhub-powered quotes for US equities and global crypto, with Yahoo Finance candles as a cached fallback when upstream wobbles.

Three-tier verification

Identity (Zauthy selfie + ID), proof of address, and a short financial survey - each tier unlocks higher deposit and withdrawal limits, admin-configurable per action.

Multi-rail funding

Stripe (card, ACH, Apple Pay, Google Pay), Paystack across NGN / GHS / KES / ZAR / EGP, and on-chain crypto deposits - all HMAC-verified on the webhook.

Brokerage-grade auth

Face / Touch ID, 6-digit passcode, and Google Authenticator-compatible TOTP - composable per-action gates on trades, transfers, and withdrawals.

Live news pipeline

A 3-hour cron pulls Finnhub headlines into a local cache and serves them to both the mobile app and the public /news page - no third-party widgets.

Refer & Earn

Lazy-generated referral codes, a 90-day attribution cookie, and admin-tunable reward + minimum-deposit knobs that credit automatically on a qualifying first deposit.

How it works

From Get Started to your first trade.

A warm-up screen, an email + phone signup, a tiered verification flow, and an atomic ledger sitting behind every buy and sell.

01

Sign up

Land on the Get Started warm screen, then create an account with email + phone. Biometrics and a 6-digit passcode are wired in on first launch.

02

Verify identity

Tier 1 (Zauthy selfie + ID) clears in under 90 seconds and lets you trade. Add proof of address and a short income survey to lift deposit and withdrawal caps.

03

Fund and trade

Top up via Stripe, Paystack, or on-chain crypto - every webhook is HMAC-verified. Place fractional buys and sells against an atomic ledger with admin-configurable commission + spread.

Trade pricing is commission + spread per SiteSettings. Funding rails and per-tier limits are admin-tunable in the dashboard.
