ETH and WETH
Why a pool may require wrapped Ether.
Native and wrapped assets
ETH pays network gas and is the native asset of Robinhood Chain. WETH is the tokenised form used by pools that expect ERC-20 assets. Wrapping converts between the two through the WETH contract.
A V4 pool can use native ETH directly, represented by the zero address in its pool key. A WETH pair is a different currency configuration and must not be silently substituted.
Preparing a deposit
If a supported pool requires WETH and your wallet has an ETH balance instead, Flea can prepare a separate wrap transaction for the required shortfall. Review its amount in your wallet.
Keep enough native ETH for subsequent gas costs. Receiving WETH does not pay for the network fee of the next approval or deposit.
After withdrawal
The supported withdrawal flow returns the pool’s actual assets. A WETH pool can therefore return WETH rather than native ETH.
Check the asset address and symbol in the receipt. Unwrapping is a separate action unless a specific verified settlement path explicitly includes it.
