Security deposits in Bisq are BTC funds that buyer and seller lock in a multisig address together with trade funds when an offer is taken in order to help ensure that both peers follow the trading protocol. Security deposits are fully reimbursed automatically to both trading peers when the trade ends without disputes.
Security deposits are the most important tools Bisq offers to protect honest users from dishonest traders. Furthermore, requiring both parties to post a deposit increases chances that both parties will be willing to cooperate and determine amicable outcomes in case a trade doesn't go to plan.
When a trade doesn't go to plan, a portion of the offending peer's deposit can be awarded to the aggrieved trader (exact amounts are determined on a case-by-case basis). For example, it is considered a protocol violation when the buyer doesn't pay the seller as specified in the trade contract (e.g., late payment, mismatching names, wrong payment method, etc). This article lists all Bisq trading rules.
Note for new users
Security deposits create a conundrum for new users: bitcoin is required to buy bitcoin. This can be inconvenient, but it's a core part of the security protocol. The initial amount of BTC required to do a trade can vary depending on the payment method, but the bare minimum BTC required to buy more BTC (as of this writing) is 0.0065 BTC to cover the minimum security deposit and mining fees. Take a look at this article for suggestion on how to get this initial BTC without KYC (a friend, ATM, sell something, work for it, etc).
Why the hard security deposit requirement? Bisq never custodies your funds, and it avoids reputation mechanisms that would weaken your privacy (e.g., reviews: to such reputation data, it must be stored somewhere and tied to an identity). Such mechanisms and would only give a false sense of security anyway due to sybil attacks.
Recommended amounts
Bisq allows offer makers to choose a security deposit percentage: minimum is 15% of trade amount and maximum is 50% of trade amount (absolute minimum is 0.006 BTC). The offer taker must deposit the same amount as the offer maker.
When creating an offer, Bisq recommends a security deposit based on recent volatility of the asset being traded: the higher the volatility, the higher the recommended security deposit. Using the recommended amount helps prevent trades from becoming future trades where the BTC buyer only sends payment to settle the trade if the BTC price has not fallen enough to compensate for losing the security deposit.

Deposits and trade amounts are locked in the multisignature address to secure trades. So a peer selling 1 BTC who chooses to specify a 25% security deposit when making his offer will need to lock 1.25 BTC, which would require the buyer to lock 0.25 BTC when taking the offer. Ultimately, this means 1.5 BTC will be locked in a 2-of-2 multisig address when the deposit transaction is confirmed, and only at that point can the buyer send payment to the seller. |
When taking an offer, the security deposit set by the maker can be viewed on the Deposit BTC (%) column.
