Cove handles cross-chain execution behind the scenes so you can focus on trading. Every chain has different gas costs, so Cove uses a transparent fee model designed to keep small trades possible, protect against failed transactions, and make cross-chain trading feel seamless.
This page reflects the current fee structure. Cove is working on a simpler experience with tiers and cashback for active users.

​
At a glance

Platform Fee

1% on most chains
1–2% on Ethereum (tiered by order size)

Gas Sponsorship

Up to 5 USD in gas sponsored per trade — no need to hold native gas tokens

Minimum Trade

From 1 USD for buys
From 0.50 USD for sells
From 2.50 USD for Solana sells

​
Buy fees

Cove charges a percentage fee above the threshold and a flat minimum below it.
Applies to Solana, Base, BNB, Tempo, MegaETH, and most other supported networks.

​
DEX & aggregator fees

Cove’s platform fee is separate from the fees charged by the underlying decentralized exchanges and aggregators that execute your swap. Most trades are routed through multiple legs:
1

Your stablecoin enters the DEX

USDC is swapped for the chain’s native wrapped token (e.g. WETH on Ethereum, SOL on Solana) via a liquidity pool.
2

Native token swaps into your target

The native token is then swapped for the target token you’re buying — again through a pool.
3

Sells work in reverse

When you sell, the route flips: token → native (WETH/SOL) → USDC.
Each leg of the swap pays a small AMM pool fee (typically 0.01%–1%) charged by the venue — Uniswap V2/V3/V4, DFlow, Jupiter, and others. These fees are baked into the output amount you receive and are paid directly to liquidity providers, not to Cove.
TL;DR — Cove’s percentage fee (shown on this page) is the only fee Cove collects. Any additional price impact you see comes from the DEX pools themselves and goes to liquidity providers who make your trade possible.

​
Minimum order sizes

Minimums prevent spam, failed transactions, and trades that would cost more to execute than the trade itself.
Trade typeMinimum size
Buys$1
Sells$0.50
Solana sells$2.50
Solana sells have a higher minimum because the tiered fee floor is designed to keep fees at roughly $0.25.

​
Gas sponsorship

Cove sponsors gas so you never need to manually manage native gas tokens on each chain.

Buys

Up to 5 USD sponsored per trade

Sells

Up to 5 USD sponsored per trade

Withdrawals

Up to 5 USD sponsored per action

Transfers

Up to 5 USD sponsored per action
For buys, the platform fee helps offset the sponsored gas cost. For sells, withdrawals, and transfers, gas can be harder to offset. If the estimated gas exceeds the $5 cap, Cove asks you to approve a gas surplus before the transaction is submitted.

​
Solana rent deposit

When you send a token to a wallet that doesn’t already hold that token, Solana requires a one-time rent deposit (~$0.36 in SOL) to open the recipient’s token account on-chain.

When it applies

Only if the recipient’s token account is new — existing accounts cost nothing extra

Which actions

Withdrawals and transfers out of Cove

Deposits

When you send tokens in to Cove, you pay the rent deposit yourself through your own wallet
Cove fronts the rent deposit on-chain and recoups it as part of the withdrawal or transfer fee.
Solana’s rent mechanism reserves a small SOL balance to keep a token account alive. Without recouping this cost, an attacker could repeatedly open and close token accounts to drain sponsored funds — effectively harvesting the rent deposit each time.By passing the cost through to the user, Cove keeps gas sponsorship sustainable and prevents abuse.
This is a one-time cost per token per recipient. Once the account exists, future transfers of the same token to the same wallet won’t incur a rent deposit.

​
Gas surplus

A gas surplus is an extra amount you approve when network costs exceed Cove’s sponsorship limit.
1

Cove estimates gas

Before submitting your transaction, Cove checks the current network gas price.
2

Surplus required?

If gas exceeds the $5 sponsorship cap, Cove shows the extra cost — for example, a Telegram inline prompt like “Pay $X”.
3

You approve or skip

If you approve, the trade is submitted. If you decline, the trade is rejected before it hits the chain — you pay nothing.
If you have already set a gasSurplusBudgetUsd, trades within that budget are approved automatically without an extra prompt.
You can configure this in Settings → Gas Surplus Budget. Choose a preset or set a custom per-trade limit.
Gas Surplus Budget settings in Cove
ItemAmount
Trade size$1,000
Cove fee (1.5% — mid tier)$15
Estimated gas$12
Net remaining after gas$3
In this case, Cove can still support the trade because the fee offsets most of the gas cost.If gas were higher than the fee, Cove would ask you to cover the surplus. In extreme cases, the platform fee may be waived entirely so the transaction stays economical.

​
Bridging & consolidation

Cove may perform bridge or consolidation actions behind the scenes to keep cross-chain trading seamless. These are treated as infrastructure operations, not user trades.

Auto-bridge moves keep your balances and routing infrastructure efficient without requiring you to manually bridge funds.

​
Why this model?

On-chain execution has real costs — gas can spike, small trades can be abused, and some transactions cost more to process than the fee they generate.
The minimum fee structure means you can trade amounts as low as $1 without being locked out by percentage-based fees.
Minimum order sizes and tiered fees filter out transactions that would be unprofitable to execute or could be used to exploit the system.
The gas surplus system ensures no trade is submitted that would lose money for either side. You always see the cost before confirming.
Platform fees help offset the gas Cove sponsors on your behalf, keeping the free-gas experience viable long-term.
