Live testnet economy White-label ready

Give your players a real economy.
Stay a game studio.

The financial infrastructure behind a Web3 game — embedded wallets, a real order book, an NFT marketplace, treasury and risk controls. Your players earn, trade and cash out without ever seeing a wallet. You keep the treasury, the analytics and the fees.

20 minutes, no slides — we walk your economy through the running stack.

The problem

Every studio that wants a player economy has three bad options

None of them is "ship a great game". That is the gap this exists to close.

Option one

Build it yourself

A matching engine, custody with key management, a double-entry ledger, settlement, risk controls, compliance. Every one of them a specialty, none of them your game.

18 months and a fintech team you don't have
Option two

Bolt on a wallet SDK

Now your players need seed phrases, gas tokens and a browser extension. Every transaction is a popup, and each popup is a place to quit.

Retention dies at the first signature request
Option three

Ship without one

Players trade your items anyway — on third-party sites you don't control, can't moderate, and earn nothing from.

Your secondary market, someone else's revenue

GameFi Rails is the fourth option

One SDK. Your players get a wallet they never see, a real order book, and cash-out — inside your game, under your brand. You get the treasury, the fee share and the analytics. The financial infrastructure is ours to run and yours to profit from.

How it works

Three layers, one integration

Your game talks to one SDK. Everything below it — matching, custody, settlement, chain — is infrastructure you never have to operate.

What your player experiences

Earn, loot, trade, cash out — no wallet, ever

The entire loop below runs on this page's infrastructure right now. You can play it.

1

Play

Signs in with the account they already have. A wallet is provisioned in under a second.

2

Earn

Gameplay rewards credit your token as a real ledger entry, not a database counter.

3

Loot

Items mint as tradable assets with rarity, owned by the player.

4

Trade

Sells to another player on a real order book, with your royalty enforced at settlement.

5

Cash out

Withdraws to their own wallet — policy-gated, and only if you allow it.

Play the whole loop in Dragon Arena

A real game on the real stack — every drop and trade is a ledger transaction you can audit.

The player surface

An economy that feels like a game, not a bank

Retention mechanics — daily spins, prediction games, staking, leaderboards — shipped as white-label templates on the rails. Every balance, prize pool and payout below is the kind of number the double-entry ledger already settles today.

Concept UI from the engagement-layer roadmap. The rails underneath — balances, prize pools, payouts, rankings — are the live ledger and matching engine you can test on this site today.

White-label

Ship it as your product, not ours

Every surface — the exchange terminal, the studio console, the player wallet — is themed from design tokens. Your brand, your domain, your palette. Nothing here says GameFi Rails unless you want it to.

  • Your logo, colours and typography across every screen
  • Your domain and your support channels
  • Your studio is the counterparty your players see
  • Dedicated infrastructure on the Enterprise tier
Try it — this page rebrands live
GameFi Rails
exchange.gamefi-rails.com

Your choice follows you into the exchange, the console and the game — it is the same token set driving all of them.

Modules

Everything behind a game economy

Adopt the whole stack or just the parts you're missing — each module works standalone.

Hybrid exchange

A real order book in Rust — limit, market, IOC, FOK, post-only — with price-time priority, deterministic replay, and 97-nanosecond order placement. Kill it mid-session and it restarts to a bit-identical book.

Embedded wallets

Wallets created from your existing accounts. Keys under envelope encryption with hot/warm/cold segregation.

NFT marketplace

List, buy and sell game items with creator royalties enforced at settlement, not by convention.

Token infrastructure

Your game token with supply, distribution, holders and velocity tracked from the ledger itself.

Treasury

Studio-owned balances, fee revenue and policy-gated withdrawals with approval thresholds.

Risk engine

Wash trading, velocity abuse and price manipulation detected live on the event stream — and circuit breakers that actually fire. A simulated wash-trading ring halts its pair in seconds, automatically.

Economy analytics

Emissions versus sinks, holder concentration, selling pressure. Health, not just volume.

Game SDKs

TypeScript and Unity today, with the same typed contract and retry semantics on both.

Why you can trust it with money

Four claims, each one verifiable

Not adjectives. These are properties you can test yourself against this deployment.

1

Kill the engine mid-trade, lose nothing

The matching engine restarts to a bit-identical order book from its snapshot and event log. No lost orders, no double fills — matching is a pure function of the log.

verify: pnpm chaos
2

A wrong balance cannot hide

Every movement of value posts double-entry rows summing to zero per asset, and a job asserts it continuously. A shortfall parks in suspense and halts the pair rather than overdrafting a player.

verify: pnpm reconcile
3

Settlement is exactly-once

Trades settle through an inbox keyed to the engine's sequence, in the same transaction as the ledger write. Redelivery is a no-op, never a double-spend.

verify: kill settlement mid-stream, replay
4

The numbers are measured, not claimed

Criterion benchmarks on the real engine, and a load test that drives real orders through the whole pipeline — HTTP, queue, engine, settlement, ledger.

The integration

Four calls to a working economy

Players sign in with the account they already have. The wallet, the exchange and the marketplace are invisible infrastructure behind your game's own UI.

game-server.ts@gamefi-rails/sdk-js
import { GameFiClient } from '@gamefi-rails/sdk-js';

const gamefi = new GameFiClient({ baseUrl, apiKey });

// A player, identified however your game already does it
const player = await gamefi.createPlayer('steam:12345');

// Reward gameplay — a real ledger credit
await gamefi.reward(player.playerId, 'boss-slain');

// Loot becomes a tradable asset
await gamefi.mintNft(player.playerId, 'swords', 'Ember Fang');

// And the player cashes out on a real order book
await gamefi.placeOrder({ playerId, side: 'Sell',
                        price: '2.40', qty: '10' });

Not a mockup and not a video. Slay a dragon, earn tokens, loot an NFT, sell it to another player, and cash out on the live order book — against the same infrastructure a studio would run in production.
