Exact Input and Exact Output
Learn which swap types ERC4626WrapperHook supports and why exact-output swaps revert.
- Exact input is supported in both directions.
- Exact output is not supported (
_supportsExactOutputreturnsfalse). An exact-output swap would require minting an exact number of shares, whichvault.depositcannot guarantee. Exact-output swaps revert withÂExactOutputNotSupported.
Integrations should always construct wrapper hops as exact-input.
