I'm trying to make swap in mumbai and I'm having this issue:

@DiMiTriFrog could you use the --verbose flag and add the logs to the issue?
Make sure to remove any private data

No... it's 100% necessary?

I want to use private anon RPC

Has any way to use own RPC? I'm executing from source so i can modify it.

You can use any RPC you want but it seems like on their end the transaction is ignored as it's considered "underpriced". Increasing the value of the transaction or switching RPC might do the trick for you.

Please let me know.

[DiMiTriFrog]

You are fully right, thank you very much,

Now the issue i'm having is that in testnet there isn't a pool for the tokens I want to swap. I thought that the uniswap router was the one to do it.

From what I can see at 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD (Uniswap V3 Router on Mumbai), WETH and WMATIC can be swapped together.

@DiMiTriFrog as you're building the project from source, could you try to increasing the gas for the approve transaction?

// Line 117
let approve_tx: TransactionReceipt = token_in_contract
            .approve(router_address, amount_to_approve)
+           .gas(300000000)
            .send()
            .await?
            .await?
            .expect("Approve transaction failed");

Mind it's need to be before the send() call

Sure, sorry.

Now i have this output:_

Amount to approve specified. Approving 4 tokens.
Error: (code: -32000, message: exceeds block gas limit, data: None)

😭😭

[DiMiTriFrog]

Is there anything else I can try?

[azerpas]

@DiMiTriFrog Playing with the gas() function to find the right amount is the only option I can think of atm...

Something that you could try that I haven't tried is use the estimate_gas() func.

        // Approve the router to spend USDT
        let approve_tx = token_in_contract
            .approve(router_address, amount_to_approve);

        let approve_tx_gas = approve_tx.estimate_gas().await?;

        if args.verbose {
            println!("Approve transaction gas estimate: {}", approve_tx_gas);
        }

        let approve_tx: TransactionReceipt = approve_tx
            .gas(approve_tx_gas)
            .send()
            .await?
            .await?
            .expect("Approve transaction failed");

I appreciate too very much your help, these function is so useful for me, but is still not working.

I change my tests to Sepolia and now I have a new error output.

I'm using as input token wETH 0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14
and as output token UNI 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984.

I swapped previously using Uniswap UI and when i tried to do the same using the CLI using this command ->

cargo run -- -u https://ethereum-sepolia.blockpi.network/v1/rpc/public -n 11155111 -a 2000000000000000000 -s 1000000 -i 0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14 -o 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 --verbose

But after executing it, i have this output ->

@DiMiTriFrog from their docs it says Uniswap contracts are deployed on Sepolia but I can't find the Quoter and Router adresses.

FYI I'm using Goerli for my tests which has the contracts deployed at the same addresses.

Error: Contract call reverted with data: 0x

There is some. way to force to push the transaction to check it failure transaction on explorer?, like allow_revert

Thanks!

@DiMiTriFrog please add the whole logs with the params used in the command. I suspect that the contract reverts because of insufficient funds. You should be able to see the error details easily with Alchemy RPC requests logs.

[DiMiTriFrog]

Could you show me an example with command that how to swap ETH to other contract in Goerli?

[DiMiTriFrog]

I clean all packages and now is working, the command for goerli i'm using to swap WETH to UNI:

cargo run -- -u https://eth-goerli.public.blastapi.io -n 5 -a 1000000000000000000 -s 1000000000000000 -o 0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6 -i 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 --verbose

Thank you very much.
