** Ethereum: Layer2 returned the notebook
Hi stack overflow of a community,
I work over the tokens in the base line Layer2, Uniswap V3 and Ethers.js. I firmly united the transaction using the Aduppue feature, but they don’t apply with the spoon that hits my swap.
The problem occurs when the Rexeinputsingle call with a curious parameter, especially when the ‘Excch.Swapexacttokensfortharate’ call is called. These Conquret variants were released by evaluating Vozurati in Uniswap V3.
background
Uniswap V3 imposes several features of the toke’s toke on the network of 2. Two Naibles Proponated Initials – SwapexacttkensForeth and Banck.SwapexactsForethwith. At this time how to allow the function to allow you to correctly adjust the replacement, they have different sets of parameters and templates for use.
Problem: Top small businesses with Uniswap V3
At that timeRectinputsingle ‘he accepts the object with the defined parameters included:
Utumin(the sadness of the tokena)
Summout(Token’s amounts per output)
to(buying)
Paindid(identification parts for application for company)
However, when using Rextinputsingle 'we need to transfer conventional parameters to escape that potential problems will escape. One of these parameters is "Gasprice", which shows the shade of the gas for the others.
In the Uniswap V3, callExcch.SwaPexaccTokensnesses ‘with the same entrance parameters that I am Empulinputsingle’ will reach the dust echoing as follows.
- The shadow of the Gazae, referred to in
Excch.SwapexacttokensForethherate, without being consumed with shady gas, sent ‘Excch.SwapexCTOKTOKESTOKESSSFOREWITHRATHRA. This is the neatler of the implementation to the non -deserted result, which will be attached to the viewer.
- We are still voiced by the neighboring accent, calling the function with the parameters once everything, it is possible to release the problems from their different models.
Solving
To resolve this problem, you must use Excch.Swapexacttokensfhetthherate here’s a fragment of a conjugated code:
`Javascript
Import * How Uniswap from '@uniswap/v3-core';
{Euters} import;
// Install the dusk gas shade
CONST GASPRICE = New Euters.providers.GaspriceProvider (
Process.env.alliance_gas_price,
New Ether.providers.Kilohoppprovider ()
);
// Create the UNISWAP copy with a replacement of the shadow on the gas
const uniswap = new uniswap ({
Postener: New Euters.providers.flexteway (
New Euters.providers.ethereumProvider (process.env.ethereum_address, process.env.alliance_url),
Gasprice,
{
Teple: process.env.chain_id,
}
),
});
// Call the swap feature
Uniswap.Swapexakttokensforate (
Token,
Tokensout,
That,
[Gasprice],
{Summin: tokensin, sutrout: tokensout, to: ethto}
);
USPOLZA Excch.SwaPexacttokensforthethrate with the correct shade depositors to the gas and the transition of the narrow parameters you can crack the dust mucosa.
Conclusion
Such an image, during the tokens right in Uniswap V3 with ETS.js, mandatory use Excch.Swapexackensfortharate. This lingerie guarantees that your sweatshirt dust will be properly without Voracle. If you still have a table of problems, influence the more information information on oblivion or the specific fragment of the code.
