Mettle: launch your own white-label prop firm

Mettle is a complete, white-label proprietary-trading firm in one codebase. It gives you everything needed to run a funded-trader evaluation business: a deterministic, replayable evaluation engine, a double-entry money ledger, a Filament operator admin, a server-rendered trader web portal, and a native Flutter app for iOS and Android. Traders buy an evaluation, trade against disclosed rules in a simulated environment, pass, get funded, and withdraw real profit at their split. You bring the brand. The hard part is built.

Important: Mettle is a simulated, educational, skill-assessment trading platform. It is not a betting, gambling, or wagering product. Evaluations run in a paper environment marked to a live price feed. No order is placed in a real market.

Why run a prop firm currently

The funded-trader model has grown into one of the most recognized revenue stacks in retail finance. The mechanics are simple and proven: a trader pays a fee to take an evaluation, the firm assesses skill against a clear rule set, and successful traders trade a funded account while the firm keeps a share of profits. Demand from retail traders who want capital, but lack it, keeps growing across every region.

• Recurring, scalable revenue. Evaluation fees come in on every challenge, resets and add-ons recur per account, scaling plans grow account sizes and fees, and affiliates drive volume. One install, multiple revenue lines.
• Low capital risk, high margins. Because evaluations are simulated, you are selling a skill-assessment product, not exposing house capital on every account. Costs scale with software and providers, not with trader losses.
• Global, growing demand. Retail traders worldwide want funding and are willing to pay for a fair shot at it. A branded firm with clear rules and verifiable payouts stands out.
• White-label speed. Instead of a six-to-twelve month build on the one thing that must be correct, the breach and ledger logic, you launch a branded firm fast on a tested core.

This is software you operate. It does not promise income, returns, or guaranteed results, and it contains no betting, odds, or wagering mechanics. Your earnings depend on your market, your pricing, and your operations.

Who this is for

• Aspiring prop-firm founders launching a clean, defensible brand without rebuilding the engine and the books from scratch.
• Existing firms that want to own their stack outright instead of paying a per-seat platform tax as they scale.
• Fintech operators and trading educators monetizing a community with a funded program that looks and behaves like an institution.
• Agencies and resellers offering white-label firm setups to clients, each instance fully branded.

Everything included

• Deterministic evaluation engine. A framework-free PHP core with profit targets, daily, overall and trailing drawdown, phases (one-step and two-step), minimum trading days, and instant funding. It re-derives every account from immutable trades and equity snapshots, so any result reproduces exactly.
• Double-entry ledger. Fees, profit splits, payouts and commissions recorded as balanced, append-only, idempotent entries. Corrections are compensating entries, never edits. The books always tie out.
• Filament operator admin. A full back office for programs, accounts, the payouts queue, KYC review, referrals, broadcasts, branding and settings. Programs are data, so you add as many as you like without touching code.
• Server-rendered trader portal. A polished Blade web dashboard with live account meters, a buy flow, payouts, KYC and referrals. Runs on any PHP shared host.
• Flutter mobile app. A native iOS and Android companion with biometric unlock, live account meters, payouts, and push notifications.
• Payments built in. Stripe, Paystack and USDT behind a provider-agnostic gateway. Demo in sandbox or manual mode without keys, go live by pasting your own.
• Three-tier KYC. Identity, address and income verification with document upload, plus manual review or Prembly, Dojah and Sumsub providers. KYC gates funding and payouts.
• Referrals and affiliates. Ledger-backed commissions with clawback and KYC-gated settlement, a growth engine out of the box.
• Push and broadcasts. Firebase push plus an admin broadcast tool that reaches traders by push, email and in-app banners. Target everyone or a segment.
• Legal pages CMS. Edit Terms, Privacy, Refund and Risk-disclosure content from the admin. Links render only when set, so nothing points at the author’s domain.
• Admin-editable integration keys. Paste payment, KYC, email and chat keys in the admin Integrations panel, stored encrypted, instead of editing files.
• Full white-label branding. Set brand name, accent color and theme from the admin. They apply across the web, the admin and the app, while the premium base design stays consistent on every instance.

Built to prove it

Trust is the product in this category, and Mettle is engineered so the firm can always show its work.

• Deterministic replay. Re-run any account from raw trades and snapshots and reproduce its exact lifecycle. On a breach, a trader sees the precise rule, its limit, the observed value that crossed it, and the triggering trade. A disagreement ends with a replay, not an argument.
• Double-entry books. Every movement of money is balanced and reconciled. There is no single wallet column to fudge, so your numbers tie out for you, your traders and your accountant.
• Append-only audit log. Operator actions, payout approvals and KYC verdicts are recorded and exportable, the compliance posture a serious firm needs in front of a processor or an auditor.

Tech stack

• Laravel 13 with Sanctum token auth, serving both the web and the mobile clients.
• Filament 5 for the operator admin panel.
• Framework-free PHP engine, the tested domain core that powers replay and reconcile.
• Flutter 3 for the mobile app, using Riverpod, Dio, GoRouter and fl_chart.
• MySQL for storage, with a server-rendered Blade portal that runs on any PHP 8.3 host.

What you can configure

• Branding: name, accent color, logo, favicon and theme, applied everywhere.
• Programs and pricing: account sizes, profit targets, drawdown rules, minimum days, fees, splits and phases, all stored in the database and edited from the admin.
• Payment and KYC providers: choose your gateways and identity provider, then paste keys in the admin Integrations panel.
• Legal pages: Terms, Privacy, Refund and Risk-disclosure content, managed in the admin CMS.
• Payout thresholds and tiered KYC gates: set when verification is required and what each tier unlocks.

Third-party services and costs

Mettle is the software only. It connects to third-party services that you sign up for under your own accounts. All usage fees, subscription costs and per-transaction charges for these providers are billed directly by them and are not included in the item price:

• Stripe and Paystack for payments.
• Firebase for mobile push notifications.
• KYC providers: Prembly, Dojah or Sumsub for identity verification.
• Email transport for transactional messages.
• Any optional broker or trade-source feed you connect.

You bring your own service accounts and pay those providers separately. You can run a full demo in sandbox or manual mode with no third-party keys at all.

Documentation and installation

The package ships with standalone, offline HTML documentation covering requirements, a step-by-step installation, configuration, the admin guide, the mobile build and the third-party cost disclaimer. A guided web installer walks non-technical buyers through requirements, database and configuration to a finished setup, so you do not need to edit files by hand. Vendor libraries and compiled assets are intentionally not shipped: you run Composer and the asset build during install, as the documentation describes.

Support and updates

Your purchase includes the support term and free updates stated on this item page. For support, use the item comments and the support channel listed here. When reporting an issue, include your PHP, Composer, MySQL and Flutter versions, the command you ran, and the relevant log output.
