What actually happens to my swap if the stablecoin I am receiving breaks its dollar peg halfway through
You get the broken stablecoin at the prevailing market rate, not at $1. The exchanger does not pause or reverse the swap because a peg breaks. Once your transaction is submitted and confirmed, the exchange rate is locked at that moment - whatever the stablecoin is worth then is what you receive.

You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. merrychristmassol.xyz never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.
Why the swap completes regardless
Stablecoins are not guaranteed by the exchanger. They are third-party tokens that aim to maintain a $1 value through various mechanisms: reserves of cash and equivalents (USDT, USDC), overcollateralised crypto positions (DAI), or algorithmic supply adjustments (historically, UST). When any of these mechanisms fail, the token trades below $1 on the open market.
The exchanger works with live market data. It does not hold an inventory of stablecoins at a fixed $1 value. Instead, it sources liquidity from decentralised exchanges and aggregated order books. When you initiate a swap, the system fetches a real-time quote. That quote reflects the current trading price of the stablecoin you are receiving. If the peg has slipped to $0.97, the quote will show you receiving proportionally less value.
Your swap is a series of atomic transactions on blockchains. Once the first transaction confirms (for example, sending your Bitcoin or ETH into the swap contract), the output is determined. There is no “wait and see if the peg recovers” feature. The blockchain does not know or care what a stablecoin is supposed to be worth - it executes the smart contract logic as written.
What this means in practice
Imagine you swap 1 ETH for USDC when ETH is at $3,000 and USDC is trading at $1.00. The quote promises you 3,000 USDC. But between the moment you click “swap” and the moment the transaction lands on-chain, USDC loses its peg and trades at $0.90. You receive 3,000 USDC tokens, but their immediate market value is $2,700. You cannot undo the swap.
The same logic applies in reverse. If you are swapping a stablecoin into a volatile asset and the stablecoin breaks its peg, you lose value on the input side. The system calculates how many units of the volatile asset your broken stablecoin buys at current market rates.
How the exchanger handles extreme volatility
The exchanger uses slippage tolerance settings. When you initiate a swap, you can set a maximum acceptable deviation from the quoted rate. If the rate moves beyond that threshold during execution, the swap fails and your funds are returned (minus network fees). This protects you against sudden peg breaks during the few seconds the transaction takes to confirm. It does not protect you if the peg was already broken when you accepted the quote.
The broader context
Stablecoins are not interchangeable with dollars. They are financial instruments with counterparty risk, smart contract risk, and market risk. The hub page “Swapping into and out of stablecoins” explains the mechanics of moving between volatile assets and these pegged tokens. That page details why you always receive slightly less than the nominal value, a phenomenon that becomes dramatically more important if a stablecoin breaks its peg.
If you are swapping between stablecoins on different chains - say USDT on Ethereum to USDC on Polygon - the same rule holds. Each step of the bridge or swap uses live prices. A broken peg on either side reduces the final amount you control after bridging.
The only safe assumption
Assume any stablecoin can break its peg at any time. The longer your funds sit in a stablecoin, the more exposure you have to that risk. Swaps complete instantly. They do not wait, they do not adjust, and they do not indemnify you against the stablecoin issuer’s failure. The exchanger delivers what the market says the token is worth at the moment of execution - nothing more.
