A stablecoin pool pays off only when your share of trading fees beats price-divergence losses, network costs, and token risk.
What does break-even mean?
Break-even means your pool position ends up worth at least as much as simply holding the same tokens. Fees can make up for losses when the tokens drift apart in price, but they do not remove the risk.
In a standard 50/50 pool, arbitrage traders push the pool price toward the wider market price. If USDC slips below USDT, they buy cheaper USDC from the pool, leaving it with more USDC and less USDT. The Uniswap v2 whitepaper describes this price correction through trades against the pool’s token reserves.
Here is an illustrative estimate for a standard pool. You deposit $1,000 of each token, and USDC later trades at $0.90 while USDT stays at $1. Your pool share would be worth about $1,897, compared with $1,900 if you had held both tokens. The roughly $2.63 gap is the loss from their price divergence, before fees and network costs.
How much fee income covers that gap?
Compare your actual share of fees with the gap, then subtract your costs to add and remove liquidity. In this example, $3 in fees would leave you about 37 cents ahead of holding, before network costs. Those fees are an example, not a forecast: they depend on trading, the pool’s fee rules, and your share of its liquidity.
On Blackhole swap, the pool type affects how price changes shape that trade-off. For the full comparison, see how Blackhole swap pool types compare. A concentrated pool can earn more per dollar while trades stay inside its chosen price range, but a depeg can push it outside that range and stop fee earning until prices return or its range changes.
What should you check before choosing?
Estimate the loss at price changes you think are plausible, then compare it with realistic fee income over your planned time in the pool. Include network costs on Avalanche C-Chain, and remember that fees arrive unevenly: a quiet pool may earn little, while a burst of arbitrage trades does not guarantee future income.
Also check that both tokens are the versions you intend to hold. Circle’s USDC documentation distinguishes supported chain deployments, and a token with the same ticker can be a bridged version with different risks. A stable price target is not a promise that either token will always trade at one dollar.
For a small expected fee edge, I would favor the option with less exposure to price movement and fewer costs. On Blackhole swap, liquidity makes most sense when your fee estimate still holds after a plausible depeg and your share of network costs.
