MEXC 600% APR Explained: Earn Carnival Rules, Principal Caps and What You Actually Earn
Overview
The MEXC Earn Carnival runs from 10:00 UTC on October 26, 2026 to 09:59 UTC on November 15, 2026, a window of just under twenty days. It covers three separate offers: capped high-APR subscriptions for new users, USDT APR boosters awarded at net deposit milestones, and raised rates on selected stablecoin Earn products. The 600% figure belongs to the first of those, and applies within a principal cap of 200 USDT or 0.005 BTC.
An annualized rate and the interest you actually receive are two different quantities. A 600% APR works out to 1.6438% per day, which on the 200 USDT cap comes to 3.2877 USDT of interest daily. Understanding that conversion is more useful than remembering the headline number, because it is what tells you which of the three offers fits the amount you hold.
Key Takeaways
Item | Detail |
Campaign period | 10:00 UTC October 26, 2026 to 09:59 UTC November 15, 2026 |
Highest new user APR | 600% on USDT and BTC, 200% on ETH |
New user eligibility | Accounts that had never completed a first deposit on MEXC before the event |
New user principal caps | 200 USDT, 0.005 BTC, 0.1 ETH |
Net deposit boosters | 15%, 20% and 30%, applying to $2,500, $5,000 and $10,000 of principal respectively |
Booster qualifying condition | Reach the milestone and maintain the qualifying amount for 3 days |
Stablecoin products | USD1 up to 11%, USDT Earn Plus up to 10%, USDC up to 6%, USDGO and spot-held USDD or USDE up to 5%, all with no subscription cap |
Basis of interest | Annualized rates, with actual interest depending on the subscription amount and each product's actual accrual period |
The Campaign Period and Who Each Offer Covers
The three offers address different users and different amounts of capital, rather than restating one set of conditions three ways. The new user allocation opens only to accounts with no prior first deposit, carrying the highest APR against the lowest principal caps. The net deposit boosters scale with newly added funds, with caps rising by tier. The stablecoin rates are open to any user who meets the product eligibility requirements, at promotional levels within a conventional range, and with no subscription cap at all.
Offer | Who it covers | APR range | Principal cap |
New user exclusive | Accounts with no first deposit before the event | 200% to 600% | 200 USDT, 0.005 BTC, 0.1 ETH |
Net deposit boosters | Users reaching a net deposit milestone | 15% to 30% on the boosted portion | $2,500 to $10,000 |
Stablecoin Earn | Users meeting product eligibility requirements | 5% to 11% | None |
The three do not exclude one another. A new user who fills the 200 USDT allocation can continue depositing to reach a net deposit milestone and receive the corresponding booster, while any remaining balance can go into the uncapped stablecoin products.
New User Exclusive: The Caps Behind 600% APR
Caps and daily interest by asset
The announcement publishes two numbers for each asset, an annualized rate and an interest-bearing principal cap. Converting the pair to a daily basis gives the interest each cap produces. The table below uses a 365-day year, and the dollar equivalents for the BTC and ETH caps use CoinGecko prices as of 06:35 UTC on October 30, purely to indicate scale.
Asset | Campaign APR | Interest-bearing cap | Cap in dollar terms | Daily interest | Over 7 days |
USDT | 600% | 200 USDT | $200 | 3.2877 USDT | 23.01 USDT |
BTC | 600% | 0.005 BTC | About $392.59 | 0.00008219 BTC | 0.00057534 BTC |
ETH | 200% | 0.1 ETH | About $224.55 | 0.00054795 ETH | 0.00383562 ETH |
Principal above the cap does not earn the campaign rate. Under MEXC's published booster rules, only principal up to the interest-bearing cap receives the raised APR, and amounts added after the cap is reached do not.
Why 600% APR does not mean six times your principal
An annualized rate describes what a sum would produce if held continuously for a full year, and this campaign runs for just under twenty days. Held from the opening to the close of the campaign, the 200 USDT cap at 600% APR produces 65.75 USDT of interest. That figure is easier to place from another angle: over the same twenty days, $65.75 of interest is what roughly $10,900 of principal generates at 11% APR. A high rate inside a small cap raises the yield on a small balance rather than enlarging the absolute amount.
Which offer to use therefore depends on the size of the balance. At a few hundred dollars, the new user allocation delivers a materially higher yield than the alternatives. At several thousand to tens of thousands of dollars, the uncapped stablecoin products and the net deposit boosters produce more interest in absolute terms.
Net Deposit Milestones and the USDT APR Booster
The three tiers
Net deposit means deposits less withdrawals over the campaign period. After reaching a tier, the qualifying amount must be maintained for 3 days to receive the corresponding USDT APR booster.
Net deposit | Booster APR | Principal it applies to | Daily interest on the boosted portion |
$2,500 to $4,999 | 15% | $2,500 | $1.03 |
$5,000 to $9,999 | 20% | $5,000 | $2.74 |
$10,000 and above | 30% | $10,000 | $8.22 |
Those daily figures cover the boosted portion alone and exclude the base APR of whichever product the booster is applied to. Base rates move with market conditions, and current levels appear on the MEXC Earn page.
When a booster takes effect and when it stops
Under MEXC's published booster rules, a booster raises the APR only on interest accrued inside its validity window, and interest outside that window accrues at the base rate. Each booster carries a minimum usage amount, and the subscribed principal must continuously meet it: the boost stops if the balance falls below the minimum, and can be reactivated if the balance is restored, though newly added principal has its own accrual start time and receives no boost if that start falls after the window closes. On a partial redemption that leaves the balance at or above the minimum, the boost continues. Boosters apply to Flexible Savings and Futures Earn, cannot be transferred to another account, and the boosted interest is paid to the spot account on the linked product's settlement schedule.
When several boosters are held at once, their boost periods queue in the order they were redeemed and begin automatically as the previous one ends, rather than stacking.
Stablecoin Earn: The Uncapped Portion
The stablecoin rates raised for the campaign carry no subscription cap and are open to users who meet the product eligibility requirements.
Product | Highest campaign APR | Subscription cap |
USD1 | 11% | None |
USDT Earn Plus | 10% | None |
USDC | 6% | None |
USDGO | 5% | None |
USDD or USDE held in the spot account | 5% | None |
On $10,000 held for 30 days, 11% produces $90.41, 10% produces $82.19, 6% produces $49.32 and 5% produces $41.10. These are the highest levels available during the campaign, and the rate that actually applies moves with each product's tiering rules and with market conditions.
USDT Earn Plus works differently from a fixed-rate product. Per the MEXC Earn Service Agreement, a user deposits USDT or another supported stablecoin and receives daily distributions, with MEXC allocating the deposits into products such as USDGO and USDC at a variable rather than fixed APR. Each distribution is added to the principal, so later payouts are calculated on the updated balance, producing a compounding effect. Holding USDD or USDE in the spot account is a hold-to-earn arrangement that requires no separate subscription.
How to Take Part, and the Accrual Details
Participation
Taking part requires a registered and verified account, and confirmation that the relevant Earn products are available in your region. The new user allocation depends on having had no prior first deposit, which makes the deposit itself part of the eligibility test. After depositing, select the product on the Earn page and subscribe up to the cap. A net deposit booster is issued once the qualifying amount has been held for 3 days, and then has to be applied to an eligible Earn order within its validity window to take effect. Subscription entry points and remaining allocation for each tier are shown on the campaign page.
Three timing rules that govern flexible-term accrual
Returns on flexible-term products do not begin accruing at the moment of subscription. Per the MEXC Earn Service Agreement, returns begin accruing from the day after the subscription and are paid daily to the spot account, a position must be held for a full 24 hours to earn that day's return, and redeeming before 02:00 UTC forfeits that day's return. Together these three rules mean the number of accruing days is usually fewer than the number of calendar days held, and they are the main source of the gap between an annualized rate and the interest actually received. Fixed-term products instead pay principal and return together at expiry and cannot be redeemed before then.
This month's market news is covered separately, and the timeline and figures for the October 29 Binance security incident are set out in that report. The product range and fee structure of the MEXC platform itself are documented separately as well.
Exclusive View from James Mitchell
The part of a high-APR campaign most often misread is not the rate but the pairing of rate and cap. A 600% APR against a 200 USDT cap and an 11% APR with no cap point mathematically at completely different amounts of capital. The first lifts the yield on a small balance to a very high level, producing 65.75 USDT over twenty days. The second produces $90.41 on $10,000 over thirty days. Neither is better; they fit different balances. What a campaign page should actually resolve is which tier a reader belongs to, answerable in about thirty seconds, rather than which percentage is largest.
The accrual rules are the second thing that gets overlooked, and they carry a real cost. Flexible-term products accrue from the following day, require a full 24 hours for a day to count, and forfeit the day's return on redemption before 02:00 UTC. Stacked together, a position held across five calendar days may accrue for only three or four. At a 600% rate, one lost day is 3.2877 USDT, about 5% of the full twenty-day figure. For short-duration high-rate offers, the timing of subscription and redemption affects the outcome more than the choice of product does.
On the net deposit tiers, the 30% booster applies to $10,000 and contributes $8.22 per day, and that is an increment on top of the product's base APR rather than the whole return. Treating the booster as the total APR understates the result; treating its validity window as open-ended overstates it. A booster raises only the interest accrued inside its window, which is stated in the rules and almost always dropped in the retelling.
FAQ
How much principal does MEXC's 600% APR cover?
The 600% rate applies within the new user allocation to 200 USDT or 0.005 BTC. ETH carries a campaign rate of 200% on a cap of 0.1 ETH. Principal above those caps does not earn the campaign rate.
Who counts as a new user?
An account that had never completed a first deposit on MEXC before the event. Accounts with a prior deposit are not eligible for the new user allocation but can still take part in the net deposit tiers and the stablecoin products.
What does 600% APR produce over twenty days?
On the 200 USDT cap and a 365-day year, interest runs at 3.2877 USDT per day, reaching 23.01 USDT over 7 days. The campaign period is just under twenty days, so the full-period figure is 65.75 USDT. The actual amount depends on the subscription amount and the accrual period of the product chosen.
How is a net deposit milestone calculated?
Net deposit means deposits less withdrawals over the campaign period. After reaching the $2,500, $5,000 or $10,000 tier, the qualifying amount must be maintained for 3 days to receive a USDT APR booster of 15%, 20% or 30%, applying to $2,500, $5,000 and $10,000 of principal respectively.
When does a booster stop working?
A booster raises only the interest accrued within its validity window. The subscribed principal must continuously meet the booster's minimum usage amount; the boost stops below that level and can be reactivated once the balance is restored, though newly added principal has its own accrual start time. A partial redemption that leaves the balance at or above the minimum lets the boost continue. Boosters are non-transferable, and several held at once queue in redemption order rather than stacking.
When do flexible-term products start accruing?
Returns begin accruing from the day after the subscription and are paid daily to the spot account, and a position must be held a full 24 hours for that day to count. Redeeming before 02:00 UTC forfeits that day's return. Fixed-term products pay principal and return together at expiry.
Do the stablecoin rates have a subscription cap?
The stablecoin rates raised for this campaign have no subscription cap, with USD1 up to 11%, USDT Earn Plus up to 10%, USDC up to 6%, and USDGO and spot-held USDD or USDE up to 5%. These are the highest levels available during the campaign, and the applicable rate moves with product tiering and market conditions.
How does USDT Earn Plus differ from ordinary flexible savings?
Per the MEXC Earn Service Agreement, Earn Plus pays daily distributions after a user deposits a supported stablecoin, with MEXC allocating the funds into products such as USDGO and USDC at a variable rather than fixed APR. Distributions are added to the principal, so later payouts are calculated on the updated balance, which produces a compounding effect.

Does the Binance Security Incident Put Your Ethereum Wallet at Risk? EIP-7702 and Wallet Delegation Explained
The Binance security incident on October 30, 2026 has pushed a relatively technical Ethereum feature into a much broader security discussion: EIP-7702 wallet delegation.
For ordinary Ethereum users, however, the most important question is not whether EIP-7702 appeared somewhere in the incident timeline. It is whether the same class of authorization risk could affect a personal wallet holding ETH, USDT, USDC or other Ethereum assets
2026/10/30
What Role Did EIP-7702 Authorizations Play in the Binance Hack?
That detail quickly pushed EIP-7702 into the center of the discussion. The Ethereum account-delegation mechanism allows a normal externally owned account, or EOA, to temporarily execute smart contract logic. In the Binance incident, blockchain researchers identified an EIP-7702 delegation shortly before assets were transferred from a Binance-linked hot wallet.
But there is an important distinction
