Fomo App Referral Code JOIN100 – Main Code Guide to the 10% Trading Fee Discount
What is the FOMO app referral code JOIN100? Use the main code at signup to get 10% off trading fees, cutting the 0.50% Fomo fee to 0.45% on every swap. Steps, savings tables and fixes included.
The Fomo app referral code is JOIN100. Enter the main code JOIN100 in the referral field when you create your Fomo account and you get 10% off trading fees on every swap. The fee drops from 0.50% to 0.45%, so a swap with 1,000 USDC in volume costs 4.50 instead of 5.00. Get the code applied in one click here: https://fomo.family/r/JOIN100.
This guide shows the exact signup steps, the savings at real trade sizes, and what to do if the code does not stick. Every fee example uses the standard 0.50% Fomo fee and the 0.45% fee you pay with JOIN100. For the deeper background on how the code works, start with the main Fomo app referral code guide and then come back here for the numbers.
What is the Fomo app referral code?
The Fomo app referral code is a short code you type into the referral field during signup. The current main code is JOIN100. When it is applied correctly, Fomo takes 10% off its trading fee for your account, so the 0.50% fee becomes 0.45% on every swap you make. The code does not cost you anything, it does not change the features you get, and it does not expire.
| Question | Quick answer | |
|---|---|---|
| What is the code? | JOIN100 | |
| Where do I enter it? | The referral code field during Fomo signup | |
| What do I get? | 10% off trading fees | |
| Fee with the code | 0.45% instead of 0.50% | |
| Does it expire? | No, the discount stays on your account | |
| Does it work on mobile? | Yes, the signup flow is the same in the app and browser | |
| Official link | https://fomo.family/r/JOIN100 |
The discount is applied at the account level. That means you do not enter the code again for each trade, and you do not need a coupon at checkout. Once JOIN100 is on your account, every swap is billed at the reduced rate.
How to enter the main code JOIN100
The signup takes about two minutes. Follow these steps in order and the discount is active before your first trade:
- Open https://fomo.family/r/JOIN100 in your browser or on your phone. This link pre-fills the main code for you.
- Create your account with your email or wallet sign-in method.
- On the signup screen, find the field labeled referral code. If you used the link, JOIN100 is already filled in. If not, type JOIN100 exactly, with no spaces.
- Finish the signup and confirm your email if the app asks for it.
- Before your first swap, open your account or profile page and check that the referral or discount section shows JOIN100 as active.
- Place a small first swap and compare the fee line with the table below to confirm the 0.45% rate.
If the referral field is missing, sign out, clear the page, and start again from the official link above. The field only appears during signup, so an account created without the code needs the fixes described later in this article.
What the 10% discount actually saves
The saving looks small per trade but adds up quickly, because copy traders swap often. Here is the fee on a single swap at different sizes:
| Trade size | Fee without code (0.50%) | Fee with JOIN100 (0.45%) | You save | |
|---|---|---|---|---|
| 100 USDC | 0.50 | 0.45 | 0.05 | |
| 500 USDC | 2.50 | 2.25 | 0.25 | |
| 1,000 USDC | 5.00 | 4.50 | 0.50 | |
| 5,000 USDC | 25.00 | 22.50 | 2.50 | |
| 10,000 USDC | 50.00 | 45.00 | 5.00 |
The pattern is simple: you save 10% of the fee on every swap. If you run copy trading bots or follow several traders, your monthly volume climbs fast, and the saving climbs with it.
Savings per year by trader type
To make the yearly effect concrete, here is what a trader saves with JOIN100 at three volume levels. The volume numbers include every swap you make while copying lead traders, not just your deposits.
| Trader type | Monthly volume | Yearly fee without code | Yearly fee with JOIN100 | Yearly saving | |
|---|---|---|---|---|---|
| Occasional copier | 2,000 USDC | 120 | 108 | 12 | |
| Active copier | 10,000 USDC | 600 | 540 | 60 | |
| Heavy copier | 50,000 USDC | 3,000 | 2,700 | 300 |
A heavy copier saves enough in a year to fund a full new position. You can run your own numbers with trade sizes and frequencies on the copy trading fee calculator, which compares 0.50% and 0.45% side by side.
Who benefits most from JOIN100
The main code helps every Fomo user, but three groups gain the most:
- Frequent copy traders. If you follow several lead traders and copy every signal, your swap count is high, so the 10% discount compounds across many trades.
- Large position traders. Bigger swaps mean bigger fee lines. On a 10,000 USDC swap you keep 5.00 in your pocket instead of paying it in fees.
- Long-term users. The discount does not expire, so the saving repeats every month you keep trading. Two years of active trading roughly doubles the totals in the table above.
If you only place one small swap per month, the saving is modest, but it is still free money. There is no reason to sign up without the main code.
How copy trading works on Fomo
Fomo is a mobile-first app for on-chain copy trading. You pick lead traders whose wallets you want to mirror, set your copy rules, and the app follows their swaps automatically. You keep full control of position sizes, stop rules, and which traders you follow.
| Feature | How it works on Fomo | |
|---|---|---|
| Lead trader discovery | Browse ranked traders by performance and style | |
| Copy rules | Set per-trade size, limits, and stop conditions | |
| Execution | Swaps mirror automatically when the lead trader moves | |
| Fees | 0.50% per swap, or 0.45% with code JOIN100 | |
| Chains | Solana, BSC and other major networks |
Because every mirrored position generates a swap, fee-aware traders win over time. Paying 0.45% instead of 0.50% on each mirrored trade leaves more of the lead trader edge in your account. Our Fomo app review covers the full feature set, and the Fomo copy trading guide explains the strategy side.
Pre-signup checklist
Run through this checklist before you create the account, so the code is applied on the first try:
| Check | Why it matters | |
|---|---|---|
| Start from the official JOIN100 link | The code pre-fills and cannot be mistyped | |
| Sign up, do not log in first | The referral field only appears during account creation | |
| Type JOIN100 with no spaces if entering by hand | Extra spaces make the code invalid | |
| Use an email you check | Email confirmation is part of activation | |
| Check the discount shows as active before funding | Fixes are easier before your first swap | |
| Start with a small first swap | Confirms the 0.45% rate on a real trade |

Common mistakes and fixes
Most referral problems come from the same handful of causes. Here is how to fix each one:
| Problem | Likely cause | Fix | |
|---|---|---|---|
| Code shows invalid | Extra space or typo | Delete the field and type JOIN100 again | |
| No referral field visible | You are logged in, not signing up | Sign out and start from the official link | |
| Discount not showing after signup | Code was skipped in the flow | Contact Fomo support with your signup email and the code JOIN100 | |
| Fee still reads 0.50% | Code saved but not active yet | Re-check the profile page, then restart the app | |
| Entered code after first trade | Referral applies at signup only | Ask support to attach the code to your account |
The safest path is the first one in the list: always start from https://fomo.family/r/JOIN100, because the link does the typing for you.
Your first week with JOIN100
A simple plan for the week after signup keeps you safe while the discount works for you:
| Day | Action | |
|---|---|---|
| Day 1 | Confirm the discount, then place one small test swap | |
| Day 2 | Compare the fee line against the 0.45% table above | |
| Day 3 | Browse lead traders and shortlist three that match your style | |
| Day 4 | Turn on copy trading for one trader with a small per-trade size | |
| Day 5 | Review the mirrored positions and adjust limits | |
| Day 6 | Add a second trader or increase size only if day 5 looked good | |
| Day 7 | Sum up fees paid and confirm the saving against the 0.50% rate |

Mobile vs desktop signup
The JOIN100 code works the same everywhere, but the flows differ slightly:
- Mobile app. Download Fomo, open the signup screen, and the referral field sits below the email field. The official link can open the app directly with the code filled in.
- Mobile browser. Same as the app, and the code field is on the same signup page.
- Desktop browser. The signup form shows the referral field next to your email. Paste JOIN100 and continue.
Whichever route you take, confirm the discount on your profile before you fund the account. That check takes ten seconds and prevents every fee headache later.
Frequently asked questions
What is the Fomo app referral code?
The Fomo app referral code is JOIN100. You enter the main code in the referral field during signup, and Fomo applies 10% off trading fees on your account. The fee drops from 0.50% to 0.45% on every swap, and the discount does not expire.
How much does the code save me?
You save 10% of the fee on every swap. On 1,000 USDC of monthly volume that is 0.50 per month or 6.00 per year. On 10,000 USDC of monthly volume the saving is 5.00 per month or 60.00 per year.
Is the Fomo app free to use?
Yes. Downloading Fomo and browsing lead traders is free. The app charges a trading fee only when a swap executes, and with JOIN100 that fee is 0.45% instead of 0.50%.
Does JOIN100 work on iPhone and Android?
Yes. The referral code works in the Fomo app on both iPhone and Android, and in any mobile or desktop browser. The discount is tied to your account, not to the device.
Can I add the code to an existing account?
The referral field appears during signup, so the cleanest path is to apply JOIN100 when you create the account. If you already signed up without it, contact Fomo support with your signup email and ask them to attach the main code JOIN100.
Why does my fee still show 0.50%?
First check that JOIN100 shows as active on your profile page. If it does, close and reopen the app, because the fee display can cache the old rate. If the rate is still wrong after a restart, contact support with a screenshot of your profile.
Do I need the code again for each trade?
No. The code is applied once at the account level. After signup, every swap is billed at the discounted 0.45% rate with no extra steps.
Does the discount expire?
No. Once JOIN100 is active on your account, the 10% discount stays for as long as you keep the account. There is no renewal and no coupon to re-enter.
Can I combine JOIN100 with other offers?
The referral discount applies to trading fees. If Fomo runs separate promotions, they apply to other parts of the product. Check the promotions page in the app for anything that stacks.
What happens if I sign up without a code?
Your account works the same, but you pay the full 0.50% fee. That is 10% more on every swap for the life of the account, so it pays to create the account through the official JOIN100 link.
Is Fomo good for beginners?
Yes. The app is built for mobile-first copy trading, so you can follow experienced lead traders without running your own strategy. Start with small per-trade sizes, use stop rules, and read our Fomo copy trading guide for the setup details.
Which chains does Fomo support?
Fomo supports Solana, BSC and other major networks, with BSC copy trading being a strong use case. Check the app for the current chain list, because new networks are added regularly.
Is my money safe when copy trading?
Copy trading mirrors real market risk: lead traders can have losing streaks, and memecoins are volatile. Use small per-trade sizes, diversify across lead traders, and never copy a wallet with money you cannot afford to lose. The discount lowers your costs, not your risk.
Where do I enter the code again?
During signup, in the referral code field, right below your email. If you start from https://fomo.family/r/JOIN100, the code fills in automatically and you only confirm it.
Wrap up
The Fomo app referral code is JOIN100, and it is the only step you need for 10% off trading fees. Enter the main code during signup, confirm it shows active, and every swap costs 0.45% instead of 0.50% from that day on. Over a year of active copy trading that saving runs from tens to hundreds of dollars depending on your volume.
