Bisq Fees and Security Deposit Explained

If you have ever opened Bisq for the first time, the popup asking you to lock up 15% of the trade amount as a refundable security deposit can feel jarring. New users coming from centralized exchanges expect a flat 0.1% taker fee and nothing else, so the idea of putting down a deposit that vanishes if you misbehave reads more like an escrow contract than a trading screen. That feeling is correct, and it is exactly the point. Bisq is not really an exchange in the Binance or Kraken sense. It is a peer-to-peer marketplace where two strangers agree to swap fiat for cryptocurrency without any intermediary holding either side of the trade, and the security deposit is the mathematical glue that keeps both parties honest.

This guide breaks down every cost a Bisq trader actually pays in 2026, line by line. We cover the maker and taker fees in both BTC and BSQ, the mining fee scaling that doubled in late 2024, the 15% security deposit logic, the differences between the legacy Bisq 1 protocol and the newer Bisq 2 Easy Trade flow, and where Bisq makes sense versus where a swap aggregator like MoneroSwapper is the better tool. If you are about to make your first trade or you want to optimize an existing workflow, this is the math you need.

Why Bisq Charges Both Fees and Deposits

Centralized exchanges only need one revenue line because they control the matching engine, the custody, and the dispute process. Bisq has none of these. The order book is a distributed mesh of nodes communicating over Tor, custody lives in a 2-of-2 multisignature address that neither party controls alone, and disputes are resolved by a rotating panel of human arbitrators and mediators who are paid in BSQ, the network's native colored coin. Funding all of that without a corporate balance sheet requires two distinct economic mechanisms working in parallel.

• Trading fees pay the Bisq DAO contributors, the Tor seed node operators, the bug bounty program, and the mediator stipends. These fees are denominated in either BTC or BSQ, with BSQ offering a meaningful discount because paying in BSQ also burns the coin and reduces supply.
• Mining fees pay the Bitcoin miners who confirm the deposit, payout, and (when applicable) refund transactions. Bisq pre-funds these at the time the offer is placed so neither party can hold the other hostage during a fee spike.
• Security deposits are not revenue at all. They are escrowed collateral locked into the multisig alongside the trade amount, refunded when the trade settles peacefully, and forfeited to the DAO only if a trader refuses to confirm a legitimate fiat payment.

Understanding this split matters because the security deposit is, in almost every honest scenario, a temporary capital lockup rather than a cost. It is the deposit that lets two anonymous parties swap thousands of dollars without ever needing to trust each other, and without ever asking a third party to take custody. Once you internalize that distinction, the Bisq fee schedule stops looking expensive and starts looking like an insurance premium on a self-custodial trade.

The Full 2026 Fee Schedule

Bisq 1 still handles most BTC-to-fiat and altcoin-to-BTC trades because the Bisq 2 rollout has prioritized Lightning and stablecoin flows first. The fees below apply to the classic Bisq 1 protocol, which is what you encounter when you swap BTC for EUR via SEPA or buy XMR with BTC over Tor.

Action	Fee in BTC	Fee in BSQ	Notes
Maker fee (creating an offer)	0.10% of trade amount, min 0.00005 BTC	0.05% of trade amount, min 1.5 BSQ	BSQ path roughly halves the cost
Taker fee (taking an existing offer)	0.70% of trade amount, min 0.00035 BTC	0.35% of trade amount, min 10.5 BSQ	Taker pays more because they trigger settlement
Mining fee (deposit + payout)	~0.00004 to 0.00012 BTC depending on mempool	n/a	Auto-adjusted from a fee estimation service
Security deposit (buyer and seller)	15% of trade amount, min 0.0006 BTC	n/a	Refundable, not a fee
Arbitration (only if dispute escalates)	Forfeit deposit, partial or full	n/a	Funds the DAO and the arbitrator

Two practical observations follow from this table. First, the BSQ discount is genuinely large. Burning BSQ instead of paying BTC cuts your trading fee in half and contributes to the deflationary pressure on the governance token, which has historically rewarded long-term contributors. The catch is that BSQ has its own thin order book, so accumulating a stash for fee payments takes some planning. Second, the security deposit dominates the capital requirement. A 1 BTC trade requires you to lock up 1.15 BTC of your own funds on the buyer side, and the seller has to lock 0.15 BTC plus the 1 BTC they are selling. Both refunds arrive together when the buyer clicks "Confirm payment received" on the fiat leg.

How the Security Deposit Actually Works

The security deposit is the architectural feature that makes Bisq function without custody, and it is the single most misunderstood part of the platform. When two users agree to trade, the Bisq client constructs a deposit transaction that pulls funds from both wallets into a 2-of-2 multisig address. Neither party can move those funds alone. Three private keys exist for this address: one held by the buyer, one held by the seller, and one held by an arbitrator who only signs in the event of an escalated dispute. The mediator, by contrast, has no key at all and can only suggest a payout split that both parties must accept voluntarily.

This structure produces some clean incentive properties. If the fiat buyer sends a SEPA transfer and the seller confirms receipt, both parties co-sign a payout transaction that returns the deposit to each side and transfers the trade amount to the buyer. The whole sequence takes one Bitcoin block confirmation plus the time the bank takes to clear the transfer. If the seller refuses to acknowledge a payment that actually arrived, the buyer opens a mediation case, attaches a bank statement screenshot showing the wire, and the mediator proposes a payout that punishes the seller by reducing their deposit refund. Only if the seller still refuses to sign does the case escalate to arbitration, where the arbitrator uses their key to sign a payout that the dishonest party cannot block.

The security deposit is not a fee you pay to Bisq. It is collateral you post to yourself, refunded automatically when the trade completes, and forfeited only if you actively try to defraud a counterparty whose evidence is verifiable on the public banking rails.

The 15% default is calibrated to make scams unprofitable. To steal a 1 BTC trade you would need to forfeit 0.15 BTC plus accept a permanent reputation hit on a network where accounts are tied to long-lived signing keys. For larger trades, makers can raise the deposit to 50% from the offer creation dialog, which is common practice for trades above 0.5 BTC and almost mandatory for trades above 1 BTC. Some payment methods that carry chargeback risk, like Revolut or Zelle, automatically push the deposit up because the seller is exposed to reversal for up to 120 days after the trade closes.

What Counts as Misbehavior

Forfeiting a deposit is rare and always tied to verifiable wrongdoing. The arbitrator has access to chat logs from inside the trade window, the deposit transaction itself, the original offer terms, and any evidence the parties upload. The most common forfeit scenarios are sellers who claim a payment never arrived when bank records show otherwise, buyers who initiate chargebacks on PayPal or revoke SEPA transfers after receiving the BTC, and either party going completely silent past the trading window with no response to mediator contact attempts. Honest mistakes, like accidentally sending fiat from the wrong-named account or missing a payment by a day because of a bank holiday, almost always result in a full refund once explained.

Bisq 1 Versus Bisq 2 Easy Trade

The Bisq community spent most of 2024 and 2025 migrating users to Bisq 2, a redesigned client that introduces multiple trade protocols under one roof. The original 2-of-2 multisig flow described above lives on as the "MuSig" protocol within Bisq 2, but the headline feature is "Bisq Easy", a Lightning-based protocol that uses no on-chain deposit at all. Instead, Easy trades rely on a reputation score earned by the seller through prior burns of BSQ, signed account ages, and successful trade history. The buyer sends fiat first, the seller releases the satoshis over Lightning, and the seller's reputation collateral is what is at stake instead of an on-chain multisig.

This drastically changes the cost structure for small trades. A 50 EUR Bisq Easy trade in 2026 costs the buyer roughly zero in deposit lockup and the seller a Lightning routing fee of a few satoshis. There is no Bitcoin mining fee because nothing settles on chain, and the trading fee is built into the rate quoted by the seller rather than paid separately. For trades under about 500 EUR, this is overwhelmingly the better choice and explains why most new Bisq users in 2026 never interact with the classic deposit system.

The trade-off is risk concentration. Without on-chain collateral, a fraudulent seller can only be punished by destroying their reputation, which works fine at low values but breaks down for larger trades. Bisq Easy enforces a soft cap that scales with the seller's reputation tier, so a brand-new seller may be capped at 250 EUR per trade while a long-established one can quote up to 25,000 EUR. For trades above the Easy cap, or for sellers who do not want to maintain a reputation profile, the classic MuSig protocol with the 15% deposit remains the default and is unlikely to be deprecated.

A Worked Example: Buying 0.5 BTC Worth of Monero on Bisq

To make the fee math concrete, consider a realistic Bisq trade in 2026: you have 0.5 BTC and you want to convert it to Monero through a Bisq XMR-BTC offer. You scroll through the offer book, find a maker offering XMR at a 1.2% premium over CoinGecko spot, and you decide to take it. Here is exactly what leaves your wallet and when.

1. Open the offer dialog. The client shows the trade amount (0.5 BTC), the price, your security deposit (0.075 BTC at the default 15%), the taker fee (0.0035 BTC if paid in BTC, or about 110 BSQ if you have it), and the estimated mining fee for the deposit transaction (around 0.00008 BTC at typical mempool levels).
2. Confirm and broadcast the deposit transaction. Your wallet signs a transaction sending 0.5785 BTC to the multisig address (0.5 trade amount, 0.075 deposit, 0.0035 fee, 0.00008 mining). The maker simultaneously broadcasts their side, locking their 0.075 BTC security deposit. One block confirmation later the trade enters its active state.
3. Send the XMR from your side. Because this is an altcoin trade where you are the BTC seller, you transmit XMR to the maker's stealth address. You attach the transaction ID in the Bisq chat as evidence. The maker waits for ten Monero confirmations, which is the protocol default for trades of this size.
4. Maker confirms receipt. The maker clicks "Payment received" in their client, which prompts both wallets to co-sign the payout transaction. The 0.5 BTC trade amount routes to the maker, your 0.075 BTC deposit returns to you, and the maker's 0.075 BTC deposit returns to them. A second Bitcoin block confirms the payout.
5. Total cost realized. You spent 0.5 BTC plus 0.0035 BTC in taker fees plus 0.00016 BTC in mining fees (deposit plus payout). Your 0.075 BTC deposit came back. Net cost: about 0.71% on top of spot, plus the 1.2% premium the maker quoted. Total all-in: roughly 1.9% over CoinGecko.

That all-in number is the honest comparison point. A no-KYC swap through an aggregator like MoneroSwapper typically lands between 1.5% and 3% above spot depending on liquidity and source coin, and skips the deposit lockup entirely because the swap completes in minutes rather than hours. Bisq wins on philosophy and on protecting the seller's KYC-free banking history; MoneroSwapper wins on speed, simplicity, and not needing to keep a 15% capital buffer parked in multisig. Most users in 2026 use both, picking whichever fits the trade.

When Bisq's Model Is Worth the Friction

The fee plus deposit structure is not for everyone. Three user profiles consistently get the most value from accepting the lockup.

• Sellers of Bitcoin who want sustained fiat off-ramps without account closures. Banks close accounts that show repeated swap-exchange withdrawals. Selling BTC peer-to-peer through Bisq looks like ordinary person-to-person SEPA traffic on bank statements and triggers far fewer compliance flags than wires from a centralized exchange.
• Buyers who already hold BTC and want privacy coins. An on-chain XMR-BTC swap on Bisq leaves no exchange trail, never touches an order book hosted on cloud infrastructure, and produces no KYC record. The 15% deposit is a small cost compared to the privacy guarantee.
• Long-term contributors who hold BSQ. The BSQ fee discount, combined with the dividend-like compensation requests that BSQ holders can submit to the DAO, turns the security deposit into a productive piece of working capital rather than dead money. Active contributors often see net positive returns on the BSQ they hold.

For everyone else, especially first-time XMR buyers who want to convert a smaller amount of BTC, USDT, or even fiat directly into Monero in a single session, an aggregator like MoneroSwapper is the lower-friction path. It quotes a single rate, requires no deposit, completes in under thirty minutes for most pairs, and surfaces multiple no-KYC liquidity providers behind one interface so you do not have to compare prices across five different services manually.

FAQ

Is the Bisq security deposit ever lost in normal trading?

No. In a completed trade where both parties act honestly, the deposit returns in full to each side as part of the payout transaction. The only situations in which a deposit is partially or fully forfeited are escalated disputes where the arbitrator finds verifiable evidence of bad faith, such as a seller denying a fiat transfer that bank records show was received, or a buyer initiating a chargeback after the BTC was released. These cases are rare and well documented in the Bisq DAO's public arbitration history.

Can I pay all Bisq fees in BSQ to get the discount?

You can pay the maker and taker trading fees in BSQ for roughly a 50% discount, but you cannot pay the security deposit or the Bitcoin mining fees in BSQ. The deposit must be in BTC because it is locked in a Bitcoin multisig, and the mining fee must be in BTC because it is paid directly to Bitcoin miners. To accumulate BSQ, you can either buy it on the Bisq DEX itself or earn it by contributing to the project and submitting a compensation request to the DAO.

What happens to my deposit if Bisq itself disappears?

The deposit lives in a Bitcoin multisig address whose keys are stored on your local machine and your counterparty's local machine, with the arbitrator's key as a third option. Bisq the organization does not hold any of these keys and cannot move the funds. If the Bisq client became unmaintained, you could still cooperate with your counterparty using any Bitcoin-compatible multisig signing tool to release the funds. The arbitrator key adds further redundancy in case the counterparty also disappears.

Why is the taker fee seven times the maker fee?

The asymmetry is intentional. Makers post offers that sit in the order book, providing the liquidity that makes the network useful. Takers consume that liquidity and are the ones who actually trigger settlement, locking up the maker's capital in the process. Charging takers more incentivizes users to post offers rather than only consume them, which is the same logic used by traditional exchanges, just with a steeper differential because Bisq's order book is thinner and benefits more from active makers.

How does the Bisq mining fee compare to network averages?

Bisq pre-funds its deposit and payout transactions at the time the offer is created, using an estimate from a fee estimation service that targets confirmation within the next three blocks. In low-congestion periods this often runs slightly higher than what a manual fee setter would pick, because Bisq prioritizes reliable confirmation over fee optimization. In high-congestion periods, the pre-funded fee can be too low and the trade may take longer to confirm, but the protocol allows replace-by-fee bumps and the mediator can authorize fee top-ups for stuck transactions.

Is there a way to buy Monero without any deposit lockup at all?

Yes. Bisq Easy on Bisq 2 uses a reputation-based protocol with no on-chain deposit for small trades, and external no-KYC swap services like MoneroSwapper complete swaps in minutes without requiring any collateral from the user. The trade-off is that you trust either the seller's reputation (Bisq Easy) or the swap provider's escrow process (aggregators), instead of trustless multisig. For small recurring buys of Monero, the no-deposit options are usually faster and cheaper; for large trades or high-privacy requirements, the classic Bisq deposit model still has unique advantages.

Conclusion

The Bisq fee schedule and security deposit are not the obstacles they first appear to be. The trading fees fund a fully decentralized exchange that has run continuously since 2014 without ever holding a user's keys, and the security deposit is a clever piece of cryptoeconomic engineering that lets two strangers swap fiat for Bitcoin without trusting each other or any intermediary. Once you understand that the 15% lockup is collateral rather than a cost, and that the BSQ payment path can halve your fees while contributing to a deflationary token, the model starts to look like the most honest exchange design anyone has shipped.

Bisq is the right tool when sovereignty matters more than speed, when you are selling Bitcoin into fiat without wanting an exchange wire on your bank statement, or when you want to swap BTC for Monero on chain without a hosted order book in the loop. For everything else, especially fast no-KYC purchases of Monero from a wider liquidity pool, MoneroSwapper aggregates multiple swap providers behind one interface and skips the deposit step entirely. Choose the model that fits the trade, and remember that on Bisq the deposit comes back the moment both parties click "Confirm". Compare your no-KYC options for buying Monero today and pick the route that matches your privacy and speed requirements.
