paraswap-dex-lib's Issues

Subgraph endpoint update required

Hey team,

We've noticed that you're referencing a subgraph deployed on The Graph's hosted service in this repository. Just a heads-up: after June 12th, hosted service subgraph endpoints will no longer be available as the offering is being deprecated.

If you are the subgraph owner or maintainer, it's time to upgrade your subgraph to the network. This ensures everything keeps running smoothly and you get access to all the latest features and improvements. Here is a quick guide with all the upgrade steps.

If you're not the subgraph owner or maintainer, check Graph Explorer to see if the subgraph development team has already upgraded to the network. If you don’t find an upgraded subgraph, a friendly nudge to the subgraph development team would be greatly appreciated—it's a quick process that benefits everyone. Here's the upgrade guide with all the necessary steps for the subgraph development team.

Once the subgraph is upgraded to the network, you can create an API key and updated query URL in Subgraph Studio then update this repository to query from the new endpoint, https://api.studio.thegraph.com/query/<ID>/<SUBGRAPH_NAME>/<VERSION>

Need more support or have more questions? Feel free to reach out to [email protected]. We're here to help!

Cheers,

Paka

Would it be possible to include an implementation for `IBlockManager`?

The only example provided currently is DummyBlockManager, but it lacks documentation on what is the logic to back logs and how to get the header block. Any documentation or better example would be highly appreciated, thanks!

Connect v9

Hello,

I am writing you from Trezor company with a message that there is a newer version of Connect, v9. More info here: https://www.npmjs.com/package/@trezor/connect.

If you have any questions or want to report a problem, feel free to reach us.

(Not sure if this is the right repo, if not, then I am sorry.)

e2e Tests not working(resolved)

Please add support for Avalanche Fuji Testnet

Our app is deployed on Fuji - what would it take to test our paraswap dex integration on Fuji before launching on Avalanche Mainnet?

That is how Parawap looks here in Firefox 105.0

Noticed it yesterday, it's completely unusable.

Notice the second 36% part suggests:

USDT to WETH (Dfyn, 0x4c28f4) on Dfyn
WMATIC (0xeee) to USDC.e on Quickswap V3

I suspect there is some confusion in how Dfyn is treating 0xeee as its own WETH in

paraswap-dex-lib/src/dex/uniswap-v2/dfyn.ts

Lines 53 to 87 in 2293ffa

Is `generic-rfq` folder the official template to use for RFQ projects integration?

In README there's an instruction for initialize the integration.

yarn init-integration <your-dex-name>

Does it apply to RFQ system as well? Notice there's another folder named generic-rfq. Is it an official template to use for a RFQ exchange to integrate with Paraswap? Thanks!

Please make the documentation more clear

Hi Paraswap Team,

can you improve the documention. Things that i stumpled accross and would make the devs live easier:

high level archicture how the lib is basically working and what functions from a dex integration are called
Better code documentation. There some basic comments on the test files, but for example there could be more documentation in the template files where devs need to complete the code
Please make it clear what environment variables should be set. It looks like that the Tenderly variables are not enough. For example you also need the HTTP Provider set for each chain (e.g for Fantom HTTP_PROVIDER_250)

Thanks in advance,

wagmi / viem

Hi there 👋

Our code uses wagmi and viem. It would make integration a little easier if we could use these.

Would there be any interest in allowing us to add wagmi and / or viem as dependencies to the repo?

PS: I did search and didn't see this issue raised before but my search skills are notoriously bad. Apologies if this has been discussed already.

How to know which Adapter and index to use in the config?

For example: https://github.com/paraswap/paraswap-dex-lib/blob/master/src/dex/swaap-v2/config.ts#L14-L23

How are these adapter and index determined?

Issues With BalancerV2 Liquidity Bootstrapping Pool Amounts

I wanted to report an issue we’ve been having with routes including a specific token 0x5c1892bb9e42b4bf89e5b0b21542e2f8622a0bb8. It looks like its using liquidity from the Balancer V2 “Liquidity Bootstrapping Pool” id 0xe9f7be5f534057b7ed5be82553e4da3c7aaac8b40002000000000000000001f9.

I noticed that the price route that is computed usually expects a much higher USDC return over what it is actually receiving. Just speculating, but could it be related to the fact that this pool has a dynamic fee or that the pool has gradual weight updates?

AFAICT, all price routes involving the above LBP are having issues.

When simulating with Tenderly (with a fork where I set required allowances), I see that the actual swapped amount is:

Despite the route reporting that:

{
  "exchange": "BalancerV2",
  "srcAmount": "5000000000000000000000",
  "destAmount": "47226070",
  "percent": 100,
  "poolAddresses": [
    "0xe9f7be5f534057b7ed5be82553e4da3c7aaac8b4"
  ],
  "data": {
    "swaps": [
      {
        "poolId": "0xe9f7be5f534057b7ed5be82553e4da3c7aaac8b40002000000000000000001f9",
        "amount": "5000000000000000000000"
      }
    ],
    "gasUSD": "4.876344"
  }
}

Which is a 5% difference.

Paraswap won't let you swap Eth for WSTETH unless you have a huge overhead for fees.

Paraswap's gas fee calculation claims if you're swapping 10.05 Eth to WSTETH, and you have 10.059 that you do not have enough Eth for the fees. But, that's definitely more than enough Eth for covering the swap fees. You have to pull your Eth order all the way down to 10 Eth, and that's 0.059 Eth more than the amount traded. That's definitely way more than enough to cover fees.

Does kyberdmm rapresent Elastic or Classic version?

Appreciate the help, thanks!

Uniswap V3: how to update local state?

Hi! I need to fetch current state on chain and perform swaps locally (mutable and immutable ones). As I understood, I can perform immutable ones using uniswapV3Math.queryOutputs, but how can I perform mutable ones? uniswapV3Math contains _modifyPosition method, but how can I calculate ModifyPositionParams params for it if I know only params for uniswapV3Math.queryOutputs? Thank you in advance.

Integrate Clipper DEX on Optimism and Mainnet

Requesting the team consider integrating Clipper on Optimism and Eth Mainnet.

1inch and OpenOcean currently route to Clipper amongst other aggregators.

Information on interacting with the clipper exchange contracts is here - https://docs.clipper.exchange/disclaimers-and-technical/integrating-with-clipper-rfq/guides/interacting-with-the-clipper-exchange-contracts

Testnet Ropsten is going to be shutdown soon. Please add support of testnet Sepolia and Goerli.

yarn test-integration not working

Hi paraswap team,

working on swapline integration for paraswap. I tryed to run the first tests but (at least on windows) it seams that test script calls the wrong jest file

The script "script/dex-integration" calls require('../node_modules/jest-cli/build/cli').run(...) but on my node-modules their is no "cli" file within the jest-cli folder.

Can you check if the path is still valid?
