Quotes and slippage
How Flea handles a moving pool between review and execution.
What a quote means
A quote uses the pool’s current price, reserves or active liquidity and your chosen range. It calculates the assets required for the requested deposit and includes an expiry.
It is not an execution guarantee. Other transactions, token behaviour and network delays can change the result before your transaction is included.
Deposit protection
V2 and V3 deposit calls include minimum asset amounts. V4 uses an explicit liquidity amount and maximum asset amounts, rather than an unconstrained deposit-from-balances action.
After approvals, Flea refreshes the quote and checks it against the amounts and range you reviewed. A larger change requires a fresh review. Unused native currency is swept back to the receiving wallet in the supported V4 settlement flow.
Simulation
Before the final deposit, the backend simulates the exact call using your wallet address and current balances/allowances. A failed simulation prevents the interface from offering that final transaction.
Simulation reduces avoidable failures, but a successful simulation is not a guarantee against later state changes, malicious token upgrades, ordering effects or bugs in external contracts.
