@zhangzhongnan928 , please try new contract version

Hi, @zhangzhongnan928 @SmartLayer , I can see the issue.
Uniswap requests approve(0x000000000022d473030f116ddee9f6b43ac78ba3, 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff), and ST404 tries to parse 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff as tokenId.
let me fix and deploy updated contract.

@zhangzhongnan928 , this is updated contract with fixed issue https://sepolia.etherscan.io/address/0xe565EE6a0F777b8DA85f5e1aF82aDF6af403c000#code

This token cannot be added as 20 token in metamask

[oleggrib]

yes, its same as my issue
#9
I have added supportsInterface(ERC721), but it conflicts with Metamask
this is fixed contract

adding liquidity to uniswap doesn't work
https://app.uniswap.org/add/ETH/0x2b0Aaa48b5669c7979a3BCa9cCB36D7f9669D28c/10000?minPrice=0.00000000000000000000000000000000000000000000000029602&maxPrice=33782000000000000000000000000

After click add, metamask is no response

[oleggrib]

Hi, @zhangzhongnan928 , could you show me error from brower console?

[oleggrib]

most of all its problem with gas limit.
uniswap request Metamast to estimate gas and metamask reverts transaction.
1k tokens liquidity works good
to add more tokens we have to whitelist uniswap liquidity contract, because when it transfer ERC20 then lot of events emitted.

other issues with Approve fixed @zhangzhongnan928

Can Oleg check first? I'll get back to you.

I am sorry, but I dont have access to the wallet 0x8349Fc69c48aF23e030A655736375d8942De5347, which is admin of our testnet contracts
uniswap creates separate contract for each pool, so contract to whitelist will be different for each uniswap pool

for example
https://sepolia.etherscan.io/tx/0x845e21e8bf08def3320f33106cee66999750eddcb1b504f5e4ab7eb3c358ff0d#eventlog

so we have to find out desired pool and whitelist it @SmartLayer

[SmartLayer]

I think we need to redeploy it on Sepolia and attempt to create liquidity pool using uniswap api interface, the last deployment was a few days ago. we need to whitelist it and write down the process in case victor wants to see the result. I'll deploy a new version once you merged in the latest change.

Hi, @SmartLayer , all contract updates pushed, you can use script to deploy and set Admin, which is better for you
please, use command
await erc404st.connect(owner).setWhitelist(some.address, true)
to set whitelisted address, or verify contract and use Etherscan UI
