To avoid repeating the values in balance and notes check what we do here

rotki/rotkehlchen/tests/unit/decoders/test_aave_v3.py

Line 39 in 341b2ed

deposit_amount, gas_fees = '99503', '0.007154122119159412'

. Do a similar thing in the tests on this file

Seems this does not do it for non-native, but I would just add the changelog when it is all done. And not 1 changelog per entry.

Suggested change

	* :feature:`7708` rotki now properly decode WETH transactions on all supported EVM chains with native ETH
	* :feature:`7708` rotki now properly decodes all native to/from wrapped token transactions (e.g. ETH<->WETH, Matic<->WMatic) on all supported EVM chains

[LefterisJP]

Left some comments.

Also test_balancer_v1_join that failed was a remote error. We can VCR in another PR. Do not mix here

[LefterisJP]

you already did them but there is no need to tests every case for every chain if they are just repeating the logic across other evm chains.

Just 1 test per chain if other cases are repeating.

not done yet
