Description
A server-authoritative crypto wallet for roleplay servers: one in-game coin whose price random-walks every cycle while players buy and sell from bank funds, with holdings and realized/unrealized profit tracked per player. Servers sell it because a live, volatile price turns a flat economy into a speculative loop players check obsessively.

Known Failure Modes & Corrective Prompt
- Client-sent price, trusting a price from the client lets a cheater arbitrage instantly. Keep price server-side and broadcast read-only.
- Round-trip desync, handlers without AddEventHandler or firing before the wallet sync corrupt holdings. Register both sides and reply after each trade.
- Basis drift, naive partial sells break realized/unrealized P/L. Reduce basis by the average cost times shares sold.
Corrective re-prompt: "Refactor so the client never transmits a price: the server owns price, broadcasts it read-only, and computes cost/proceeds with math.floor. On partial sells, reduce basis by (basis/qty)*soldQty so P/L stays correct."
Framework Integration
ESX: swap to ESX = exports['es_extended']:getSharedObject(), xPlayer.getAccount('bank').money, removeAccountMoney/addAccountMoney, key holdings by identifier.
QBCore: as written, GetPlayer, Functions.GetMoney('bank'), RemoveMoney/AddMoney, key by citizenid.
QBox: use exports.qbx_core:GetPlayer(src) and the shared QBCore money functions; identifiers map 1:1 with QBCore.
Profit Potential
$400-$6000/mo on Tebex (expected ~$1500), priced inside the $50-389 script band against a corpus of comparable Tebex sellers (median ~$11.85K/mo); a hot crypto niche skews to the upper unit count.
Trend Signal
🔥 hot, corpus: Crypto trading is an established Tebex economy listing the scraper surfaces (tebex_topsellers cat:economy); crypto-RP demand surging pre-launch.
Sales Angle
Position as the live, speculative heartbeat of a server economy, the ticking price and P/L panel are the demo that sells it. Recommended Tebex price: $189.
