The problem Cove solves
On-chain markets are fragmented by design. Solana has its own wallets, its own gas token and its own DEXes. Base has different ones. So does Ethereum, BNB Chain, HyperEVM, Monad, MegaETH, Ink, Story, Tempo, Plasma, Arbitrum, Robinhood Chain and Stable. A trader who wants to follow opportunity across those networks traditionally needs a funded wallet on each one, a stash of each native gas token, a bridge to move value between them, and the patience to wait for bridges to settle while the trade they wanted moves on without them.
That friction has three parts:
- Manual bridging. Moving value from one chain to another is slow, has its own fees, and is where a lot of funds get lost to wrong networks and wrong addresses.
- Native gas-token management. Every chain wants its own gas token. Running out of ETH on Base while holding plenty on Arbitrum is the on-chain equivalent of having a full tank in the wrong car.
- Fragmented execution. Different DEXes, different aggregators, different interfaces, different failure modes. Each chain is a new workflow to learn.
Cove replaces all three with one idea: a unified USDC balance that funds trades on every supported chain, with Cove handling routing, bridging and gas behind the scenes. You trade intent — "buy this token" — not logistics.
What the unified balance is
Your unified balance is USDC held in your Cove account. It's one number. When you open a token panel on any supported chain, that number is what you're spending from. When you sell, proceeds settle back into it. There's no "your Solana USDC" and "your Base USDC" — from your perspective, there's just USDC.
Behind the scenes, Cove maintains the liquidity where trades happen and moves it as needed through auto-bridge consolidation: infrastructure operations that carry no user fee, need no confirmation and have their gas covered by Cove. You never see them and never approve them. You see one balance and one set of trading panels.
Depositing into the balance
You fund the balance by depositing to your Cove account. Two paths:
- Deposit USDC directly from any supported network. Cove credits your unified balance.
- Deposit another token for conversion. Cove converts it to USDC and credits the balance, so you can bring whatever you hold.
If a deposit arrives through an EVM network and must be bridged into the unified balance, a pass-through bridge fee of roughly $0.19 is deducted to cover the provider's bridging and destination account-creation cost. A $100 EVM deposit credits about $99.81. Cove doesn't sponsor inbound bridging because doing so would let automated accounts trigger the underlying cost repeatedly at Cove's expense — passing through a small fee keeps deposits reliable for everyone.
That bridge fee is the only inbound cost. Cove charges no platform fee on deposits.
Gasless: what it means and what it doesn't
Cove sponsors gas up to $5 per action — buys, sells, transfers and withdrawals. You never need to hold ETH, SOL, BNB or any other native token to transact. For the vast majority of trades on most chains, that's the whole story: gas is handled, you never think about it.
"Gasless" doesn't mean gas is infinite. When a transaction needs more than $5 of gas — Ethereum during congestion, a complex multi-hop route, a sell on a chain where gas is expensive relative to the trade — Cove asks you to approve a gas surplus before submitting. You see the extra cost as a Pay $X prompt. Approve and the trade goes through with the surplus taken from your USDC balance; decline and the trade is rejected before it touches the chain, at no cost.
Your Gas Surplus Budget in guardrails controls whether Cove asks. Set to Off, it always asks. Set to a dollar amount, surpluses under that amount are approved automatically so resting orders and fast trades don't stall waiting for a tap.
How sponsorship stays sustainable
On buys, the platform fee usually covers the sponsored gas — a 1% fee on a $200 buy is $2, and gas on most chains is well under that. On sells, transfers and withdrawals the fee is smaller or zero, so gas can exceed what the action generates. That's when the surplus mechanism and, in the rewards program, negative cashback adjustments come in. The design goal is that no single action loses money for either side, while the everyday experience stays free of gas management.
Routing: how a trade actually executes
When you tap Buy on a token panel, Cove builds a route from your USDC to the target token on the target chain. Typically:
- USDC enters the DEX and is swapped for the chain's native wrapped token — WETH on Ethereum and its L2s, SOL on Solana, and so on.
- The native token swaps into your target through a liquidity pool.
- Sells reverse the route — token → native → USDC.
Each leg pays the venue's pool fee, typically 0.01% to 1%, which is baked into your output and paid to liquidity providers, not to Cove. Cove routes across Uniswap V2/V3/V4, Jupiter, DFlow and other venues to find the best path. When a route takes more than one hop, the receipt marks it as multi-hop with a Learn more link.
The trading panel and the receipt both show you the route, so "Cove handles routing" never means "Cove hides routing." You see where the trade went.
Supported networks
Cove currently supports fourteen networks from the same unified balance and the same trading panel:
Availability of a specific token, order type, deposit route or withdrawal route can depend on current configuration, and new networks are added over time. The docs' Supported Chains page is the source of truth.
The important point is not the count but the sameness. A trader who learned Cove on Solana can trade Ink tomorrow with zero new setup — no new wallet, no new gas token, no bridge. Paste the address; the panel opens.
What the model changes in practice
You chase the market, not the plumbing
A call lands for a token on a chain you've never touched. With a conventional setup, you're bridging, buying gas, and configuring a wallet while the entry moves. With Cove, you paste the address and trade from the balance you already have. The time between "I want this" and "I have this" collapses to seconds.
Capital isn't stranded
Without a unified balance, value gets stuck: $400 of USDC on Arbitrum when the opportunity is on Base, or a pile of a native gas token you bought for one trade and never used again. With Cove, all your dry powder is one pool, deployable anywhere.
Failure modes disappear
Sending USDC to the wrong network. Running out of gas mid-sell. Bridging to a wallet you don't control. Each of these has cost traders real money and each is structurally impossible when Cove handles the movement between chains and you only ever interact with one balance.
Fees are legible
One platform fee per trade, shown before you commit, on a public schedule. Pool fees to liquidity providers, visible in the route. Pass-through costs at cost. Gas sponsored, with any surplus asked for explicitly. Compare that to the alternative — bridge fees, gas on two chains, aggregator fees and a bot fee, none of them in one place.
Manual multi-chain flow versus Cove flow
Non-custodial, still
None of this requires Cove to hold your funds. Wallets are secured through Privy in isolated enclaves separate from the trading layer. Cove has signing access you granted and can revoke. The unified balance is your USDC in your wallet; Cove orchestrates where it goes on your instruction. Read the Accounts page for the full model.
Withdrawing from the balance
When you want value out, withdraw USDC from the unified balance to any external wallet on a supported chain. Gas is sponsored up to $5. Pick the destination chain carefully — USDC on one network is not USDC on another — and expect a one-time Solana rent deposit (about $0.36, recouped in the withdrawal fee) if the destination has never held the token.
Frequently asked
Is my USDC actually on one chain? From your perspective it's one balance. Cove maintains and consolidates liquidity across chains as infrastructure; you don't manage it.
Can I deposit ETH or SOL instead of USDC? Yes — Cove converts supported tokens to USDC on deposit.
What if gas is more than $5? Cove shows the surplus and asks. Decline and nothing happens. Set a Gas Surplus Budget to approve small surpluses automatically.
Do I pay Cove to move my own money? No. Deposits, transfers and withdrawals carry no Cove platform fee. Only network-level pass-through costs apply where they exist.
What's the catch? The platform fee on trades — 1% on most chains, tiered on Ethereum and HyperEVM — is what funds sponsorship and routing. It's on the Fees page in full.
Cove's bet is that traders don't want to be bridge operators. They want to see a token, decide, and act. The unified balance and gasless execution are what make that possible across fourteen chains from one chat.
A day of trading on one balance
Morning: 1,000 USDC in your unified balance. A Solana call lands; you buy $150. Midday, a Base launch — $200, gas sponsored, no ETH held. Afternoon, a HyperEVM token; $300, tiered fee, a $1.40 gas surplus auto-approved under your $3 budget. Evening, the Solana position hits TP1 and $210 settles back into the balance. You end the day with positions on three chains, 560 USDC of dry powder, and you never opened a bridge, bought a gas token or switched wallets.
Compare the manual version: three wallets, three gas tokens, at least one bridge, and the Base launch probably missed while you were setting up.
What "supported route" means
Availability of a specific token, order type, deposit route or withdrawal route can depend on current configuration. In practice that means: most tokens with live liquidity on a supported chain trade normally; some order types may be limited on some networks at some times; and deposit and withdrawal networks are listed in the flow when you use it. The docs' Supported Chains page is updated as coverage changes — Robinhood Chain and Ink were the most recent additions.
Frequently asked
Does the unified balance earn anything while idle? No. It's USDC held for trading. The Rewards program pays cashback on trades, not on balances.
Can I hold tokens other than USDC in the balance? Positions hold the tokens you buy. The *balance* is USDC. Deposited tokens are converted to USDC on arrival.
What if a chain goes down? Trades on that chain pause; your balance and positions on other chains are unaffected. Auto-bridge consolidation resumes when the network does.
Why does an EVM deposit credit slightly less than I sent? The ~$0.19 pass-through bridge fee. It's the only inbound cost and it isn't a Cove fee.
Is there a minimum deposit? Deposit what you like; trade minimums are $1 for buys and $0.50 for sells ($2.50 on Solana).
Can I see where my USDC physically is? The Accounts view shows your wallet addresses. Cove manages chain distribution as infrastructure; you manage one number.
Where the model comes from
Cove's fee schedule is built around the economics of a unified balance. On buys, the platform fee — 1% on most chains, tiered on Ethereum and HyperEVM — funds the sponsored gas and the routing infrastructure. On sells, transfers and withdrawals, where fees are lower or zero, the surplus mechanism and the Rewards program's negative cashback adjustments prevent Cove from subsidising transactions that cost more to execute than they generate. Auto-bridge consolidation is treated as infrastructure with its own abuse protection — a 30-second cooldown per account, chain and token — so the system can't be gamed into moving liquidity around at Cove's expense. The result is a model where everyday trading feels free of plumbing while the underlying costs are covered honestly, and where the schedule is public enough that any trader can work out exactly what a given trade will cost before tapping.
