Trench.io Referral Code FAQ: JACEK and the 10% Fee Discount
By the Trench Trading Guide editorial team · Last reviewed August 26, 2026 · Editorial policy
The referral value is “jacek” and it is carried automatically by the referral link, so you normally do not type it anywhere. The referral programme states a 10% discount on fees. If the benefit is not visible in your account, do not deposit — ask Trench.io support to confirm it first.
What is the Trench.io referral code?+
The referral value used by this guide is "jacek". It is carried automatically by the link trench.io?ref=jacek, so you normally do not have to type it anywhere.
What does the JACEK referral link provide?+
The affiliate dashboard behind this link states that referrals receive 10% off fees. Trench.io's current terms decide how and when that reduction is applied, so confirm it inside your account before funding.
How do I get 10% off Trench.io fees?+
Open trench.io?ref=jacek, create your account with Google, Apple or email, then check that the referral or 10% fee benefit is attached to the account before you deposit or trade.
Do I need to enter JACEK manually?+
The link carries the referral value "jacek". Open Trench.io through the link and confirm that the benefit is shown. If Trench.io displays a code field, enter "jacek". If the discount is not confirmed, contact Trench.io before depositing.
What should I do if the discount does not appear?+
Do not deposit yet. Re-open the referral link in the same browser, check your account or fee settings again, and contact Trench.io support for written confirmation before you fund the account.
Does the referral link guarantee a profit?+
No. The referral only relates to fees. It does not make a trade more likely to succeed, and it does not protect you from losses.
Why is my Trench.io referral code not working?+
The most common causes are opening Trench.io in a different browser or app than the one where you clicked the link, an existing account created before the referral, or an ad blocker stripping the query string. Re-open the referral link directly and contact support if the benefit still is not shown.
Can I add the referral to an account I already created?+
That is not publicly documented. Referral attribution usually applies at signup, so ask Trench.io support directly instead of assuming it can be added later.
Does the 10% apply to every fee type?+
We cannot verify which fee types are covered. The referral is stated as 10% off fees; the exact scope is defined by Trench.io's current terms, which you should read before funding.
How long does the fee discount last?+
The duration is not publicly documented. Ask Trench.io support for written confirmation of the scope and duration before you deposit.
Can I share the JACEK link with friends?+
You can share it, but be clear that it is an affiliate link, that the stated benefit is 10% off fees, and that trading involves substantial risk.
Do I need to deposit to activate the referral?+
We have no verified information that a deposit is required for attribution. Do not deposit to 'unlock' a discount that is not already confirmed in your account.
Will you know who I am if I use the link?+
No. We receive only aggregate referral statistics from the affiliate programme. This website does not collect your name, email address or wallet details.
What if the offer changes after your last check?+
Our last manual check was August 26, 2026. Trench.io can change the offer at any time. If you see something different, email us and we will re-verify and correct the page.
Is the fee discount the same as a bonus or free money?+
No. It reduces fees you would otherwise pay. It does not add funds to your account and it does not offset trading losses.
