Maren fees depend on the product and asset pair. A valid referral gives you 20% off eligible Maren fees, while your inviter earns 30% of eligible revenue Maren receives from your activity for 12 months. Review the Maren fee, external costs and minimum received before authorizing an operation.
This page describes the versioned fee policy. Collection is route-specific: a tariff does not mean collection is enabled on every route. The reviewed quote must disclose whether a fee is collected. Rates below are Maren fees; network, venue, liquidity-provider and other third-party charges remain separate.
Platform fee schedule#
| Product | Standard | Referred |
|---|---|---|
| Ordinary spot swaps | 0.30% | 0.24% |
| Curated major-pair swaps | 0.05% | 0.04% |
| Hyperliquid perpetuals | 0.005% | 0.004% |
| Pure cross-chain bridges | 0.10%, capped at USD 15 | 0.08%, capped at USD 12 |
| Same-chain approved stable-to-stable swaps | 0% | 0% |
| Same-chain transfers and supported wrapping | 0% | 0% |
| Hyperliquid spot, NFTs and mints, yield operations, and predictions | 0% additional Maren fee | 0% additional Maren fee |
Curated major pricing requires both assets to match a supported pair on the relevant networks. A trade does not qualify simply because one side is ETH, SOL or a stablecoin. A swap within a yield operation follows its own pair tariff even though the yield action has no additional Maren fee.
Copy, limit, stop, DCA and chat-initiated trades use the underlying product's fee. Order placement, cancellation, quote requests and execution retries do not create additional Maren trading fees. A filled close pays its normal trading fee.
Cross-chain fees and caps#
A pure bridge moves the same verified asset across networks. Cross-chain movements between approved pegged stable assets also use the bridge tariff. Its fee is based on the source amount's reviewed USD value, with a cap for the complete operation:
- Standard: 0.10%, capped at USD 15.
- Referred: 0.08%, capped at USD 12. This is 20% off the capped standard fee.
Other cross-chain conversions use the ordinary spot rate of 0.30% / 0.24%, or the curated major-pair rate of 0.05% / 0.04% when both assets qualify. Maren charges that conversion fee once, without adding a Maren bridge fee. Internal swaps, wrapping and routing hops do not create duplicate charges.
The same-chain stable-swap exemption does not apply to a cross-chain stable transfer. Bridge-provider charges and network gas remain payable in addition to the Maren fee. The cap limits Maren's fee, not the total cost of bridging.
A failed or refunded cross-chain operation must not retain a Maren fee; any collected Maren fee must be refunded. Network and provider costs may still apply. Source-chain confirmation alone does not establish delivery on the destination network.
How fees are calculated#
Rates apply to the actual executed amount under the disclosed route's fee basis. For input-side exact-input collection, the Maren fee comes from the authorized input budget and the remaining amount is routed. Other supported routes can collect from the output; the confirmation must show the fee asset, amount and minimum received. Gas is a separate cost and is not always deducted from the swap input.
Amounts use the asset's supported precision. Rounding follows the selected route and must stay within the fee maximum you authorize. Slippage tolerance is a price-movement limit, not a separate fee.
Ordinary spot example#
Illustrative only: an eligible ordinary spot trade spending 1,000 USDC on a supported network, with input-side collection and no mandatory provider revenue share:
- Standard fee:
1,000 USDC × 0.003 = 3.00 USDC. - Referred fee:
1,000 USDC × 0.0024 = 2.40 USDC. - Friend's immediate saving:
0.60 USDC. - Input remaining for the referred swap:
997.60 USDC, before separately disclosed external costs. - Inviter's earnings:
2.40 USDC × 0.30 = 0.72 USDCafter settlement and review.
An ETH/USDC trade that qualifies as a curated major pair uses the lower pair tariff instead. For example, a referred 10,000 USDC trade at 0.04% has a 4.00 USDC Maren fee.
Bridge-cap example#
Illustrative only: for a USD 1,000 source value, the pure-bridge Maren fee is USD 1.00 standard or USD 0.80 referred. At USD 100,000, it is capped at USD 15 standard or USD 12 referred. The fee is collected in the supported asset and the quoted cap is fixed before authorization; external costs remain separate.
Perpetuals example#
Illustrative only: a USD 20,000 filled position at the standard 0.005% rate incurs a USD 1.00 Maren fee on that fill. At the referred 0.004% rate, it incurs USD 0.80. Opening and closing fills are charged separately on position notional, not on collateral deposited. Hyperliquid trading and funding charges remain separate.
Referral discount and earnings#
Give friends 20% off eligible Maren fees and earn 30% of the eligible fees Maren receives from their activity for 12 months, paid in withdrawable crypto. The friend saves immediately; the inviter receives earnings that can be claimed rather than trading-fee credits.
- Every eligible account can share its own link, including an account that joined through another user's link. Becoming an inviter preserves your own discount.
- Confirm one inviter within seven days of account creation and before your first accepted fee-bearing execution. A quote alone does not close that window. Once confirmed, the inviter cannot be replaced by a later link.
- The 12-month commission window starts when Maren first recognizes a positive settled eligible fee from the invited account, not when the account signs up. The friend's discount has no scheduled expiry under this policy.
- The 30% commission is calculated after mandatory provider revenue shares. Maren does not deduct arbitrary operating overhead from that basis.
- Eligible collected bridge fees count. Gas, liquidity-provider and protocol fees, royalties, perpetual funding, subscriptions, refunded fees and zero-fee actions do not.
- Only direct referrals earn commission. Self-referrals, controlled-account farming and manipulated activity are excluded. Shared IP alone does not establish abuse.
Attribution belongs to the Maren account across its owned wallets and networks. Creating another speed wallet or changing addresses does not duplicate benefits or restart the commission window. There is no extra discount for each signup, no additional discount for sharing a link, and no Pro discount stacking.
When sharing a link, disclose the incentive: “I earn a share of Maren's fees if you join and use eligible products.” Fee-policy changes apply prospectively; they do not increase a fee already authorized or erase earned rewards.
Claiming referral rewards#
Solana is the currently qualified payout rail, with a USD 1 equivalent minimum. The applicable asset, network and minimum must be shown before you confirm a claim. The minimum applies to available earnings in that payout asset and location; balances on different networks are not automatically combined.
Earnings first appear as pending. They become available after final settlement, receipt or allocated backing of the funds, and a 24-hour review period. Network finality or an explained review hold can take longer. A pending amount is not yet withdrawable, and a displayed USD value is an estimate of the actual token balance.
Maren sponsors claim gas from a finite treasury budget, with no additional user claim fee under this policy. If the budget is exhausted, payment is delayed while earnings remain owed. Rewards are paid in a supported earned asset; conversion and bridging into USDC or another asset are not automatic. There is no promise of instant settlement or a USD 1 claim on every network.
If a claim is pending, check its existing status and transaction reference before submitting another request. A broadcast delay is not proof that the transfer failed.
External costs, gas and limits#
Liquidity pools, venues, marketplaces, bridge providers and networks can charge separately. Provider fees or retained trade surplus can affect final output even when Maren's fee is low. Compare the final amount received, minimum received and complete cost breakdown rather than the headline percentage alone.
Gas sponsorship applies only where explicitly offered. Review who pays network costs before approving; a smart account or passkey does not itself mean gas is free. Direct speed-wallet execution needs sufficient funds for its disclosed network costs.
Review the limits and permissions attached to the executing wallet or session. A spending cap, expired permission or unsupported route can prevent execution. Fees do not expand those permissions, and an execution failure does not authorize a second trade automatically.
