"execution reverted: Insufficient WETH9" on Polygon #346DescriptionDescribe the bug
I want to transfer AMP to MATIC(not WMATIC)，but I got a error

To Reproduce
this is my code
w3 = Web3(Web3.HTTPProvider('https://rpc-mainnet.maticvigil.com',
request_kwargs={"proxies": proxies}))
w3.middleware_onion.inject(geth_poa_middleware, layer=0)
uniswap = Uniswap(address=address, private_key=private_key, version=3, web3=w3)
qty = 5 * 10 ** 18
amp = w3.to_checksum_address("0x0621d647cecbFb64b79E44302c1933cB4f27054d")
matic = w3.to_checksum_address("0x0000000000000000000000000000000000001010")
data = uniswap.make_trade(amp, matic, qty=qty, slippage=0.1, fee=3000)
print(data)
Additional context
I set in the constants.py ETH_ADDRESS = "0x0000000000000000000000000000000000001010" Activityliquid-8 commented on Sep 7, 2023 Hi! Does it work as intended if you swap the token for a wrapped matic? I haven't touched alt networks for aeons, but I remember some weird issues regarding swaps from/to native tokens. Lv5Electro commented on Sep 7, 2023
Hi! Does it work as intended if you swap the token for a wrapped matic? I haven't touched alt networks for aeons, but I remember some weird issues regarding swaps from/to native tokens.
I tried, but it transferred to WMATIC instead of MATIC liquid-8 commented on Sep 7, 2023 I would just swap token<->wmatic then unwrapping manually when needed. Basically, uni v2/v3 router calls don't swap for native tokens directly, but for wrapped first and then unwrap, so it's pretty the same. IIRC, there is a call for wrapping/unwrapping native tokens in router's contract, check ABI out. liquid-8 commented on Sep 7, 2023 zaneran9 commented on Aug 6, 2024 I tried to execute my transaction using multicall(exactInputSingle, unwrapWETH9), and it returned "execution reverted: Insufficient WETH9". Obviously, the first step was successful, and the problem was with unwrapWETH9;
I tested using the WETH9 contract to execute the withdraw method, and it was able to be withdrawn, but I used the Router contract unwrapWETH9 method to execute it, and then it returned the above error (here is my transaction record https://sepolia.etherscan.io/tx/0xfd28c046a6e41a4ac0cbf1be7219a9bcf3c2c125ae9af2ac5129c9f8f36100b1), any suggestions? Thanks!
