Description

A multi-currency exchange bureau: players swap cash into crypto or a foreign currency at a mid-rate that drifts on a server timer, paying a spread fee on every conversion. It goes beyond the usual crypto buy/sell button by modelling a live rate and a bureau cut, which gives crypto-RP economies a real FX surface and a steady money sink. The spread is the recurring drain servers pay for.

Known Failure Modes & Corrective Prompt

  • Client-side rate, exposing the rate or math lets a player swap at their chosen price. Keep both server-side.
  • Anim no-op, TaskPlayAnim before the dict loads silently fails. Wait on HasAnimDictLoaded.
  • Overdraft swap, charging without re-checking cash mints the target currency. Re-check GetMoney("cash") server-side.

Corrective re-prompt: Keep the rate table and all conversion math on the server with math.floor, re-check the held cash balance before charging, and guard the teller animation with RequestAnimDict + a while not HasAnimDictLoaded(dict) do Wait(0) end loop before TaskPlayAnim.

Framework Integration

  • ESX: port to ESX.GetPlayerFromId, getMoney/removeMoney, and addInventoryItem(to, net) for the crypto/FX item.
  • QBCore: native, Player.Functions.GetMoney/RemoveMoney("cash", ...) and AddItem(to, net) as shown.
  • QBox: drop-in via exports.qbx_core; route AddItem through ox_inventory and persist rates if you want them shared across restarts.

Profit Potential

$150-$2,000/mo on Tebex (expected ~$520), priced in the $50-389 script band against a corpus of comparable Tebex sellers (median ~$11.85K/mo); a stable, uncommon FX niche.

Trend Signal

→ stable, inferred: Beyond simple crypto buy/sell, a multi-currency spread/FX bureau is uncommon; reasoned demand pairing with crypto-RP economies.

Sales Angle

Position it above the basic crypto button, a real FX bureau with a live spread and drifting rates. Mid-to-upper band, ~$129-179 on Tebex, sold alongside a crypto economy.
