Thanks for that. I think I'll use the site recommended on Ethereum dot org's WETH page. It's been up there 11 months, added by a regular contributor, so it seems safe.

Don't send WETH to the contract directly. In my understanding, if you send ETH to the WETH contract you get WETH back, but the other way around does not work. If you send WETH directly to the contract, your WETH is simply lost. Don't do that. If you want to interact with the contract directly, use it through etherscan or something like it. Otherwise, most dexes should handle WETH wrapping and unwrapping for you without any additional fees.

> One issue: swapping WETH to ETH through MetaMask was missing the low fee option. Is there someplace better to unwrap WETH?
I gather the correct way is just to send it to the WETH contract to wrap/unwrap.

Saving 97% on gas costs when using MetaMask:
MetaMask's default gas prices are > 10x as high as necessary. You should lower them before you execute transactions:
Click the pencil by Network fee, then click Low.
Unfortunately, you have to do this every time: there's no low-fee setting. For a swap, you may have to do it for both the approval and the swap. You can customize your gas usage too, but the low fee option is simpler and seems to work well: it's closer to the gas prices I see on GasNow.
A few examples of recent savings on swap transactions: ¢3 vs ¢83, ¢2 vs ¢66, and ¢3 vs ¢85. That averages about 3.4% of the default fees.
Do other wallets use ridiculously high default fees, e.g. Rabby?
One issue: swapping WETH to ETH through MetaMask was missing the low fee option. Is there someplace better to do that if I need to do it again?

Minimum engagement example: Aerodrome vaults by Mellow finance. Fully automated. In WETH/USDC it moves the +/-3% range every 20$ making positions with ratio 98-2 or 99-1 to minimise the impermanent loss.
Rebalance free of charge.
Up more USDC, down more WETH.
All weather, set and forget.
You are welcome

> Does anybody else park their crypto on AAVE
Yes, there are almost $13 billion worth of assets parked on AAVE at the moment, it is the 2nd biggest DeFi application all of crypto.
https://defillama.com/protocol/aave
I have assets still in AAVE from the first DeFi summer that I sometimes borrow against but have never moved.
Don't really know about the AAVE governance token though, I use the platform for ETH/WETH and stablecoins.
