How to use native currency on custom network (Arbitrum 42161, Sepolia 11155111, Arbitrum Sepolia 421614)

Failed to trade ETH on custom network. Does anybody know where might be a problem ?

Tried to add _ETH to Sepolia WETH contract (0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14_ETH), but it didn't help.

This is Sepolia network config:

{ chainId: 11155111, layerZeroChainId: 10161, network: 'sepolia', currency: 'ETH', networkName: 'Sepolia Testnet', networkNameForAllEnv: NetworksEnum.Sepolia, explorerUrl: 'https://sepolia.etherscan.io', apiEndpoint: 'https://api-dev.dev-landx.be/api', infuraApiKey: 'aaabaa1e74ac4192859455ead7ca6cdd', providerUrl: 'https://sepolia.infura.io/v3/aaabaa1e74ac4192859455ead7ca6cdd', contracts: sepoliaDev, rpcUrl: 'https://ethereum-sepolia-rpc.publicnode.com', isDefault: true, isTradeShown: true, lndxSwapTokensList: [TOKENS.ETH, TOKENS.USDC, TOKENS.USDT], customChain: { cloneUniswapContractDetails: { v3Override: { routerAddress: '0x9990933B23c0D4e23dA4cb8096A478D42e687CE8', factoryAddress: '0x0227628f3F023bb0B980b67D528571c95c6DaC1c', quoterAddress: '0x6Aab9B15DA9Df02b22C8E79a0a5527E520E7D009', }, }, customNetwork: { nameNetwork: 'Sepolia', multicallContractAddress: '0xcA11bde05977b3631167028862bE2a173976CA11', nativeCurrency: { name: 'ETH Token', symbol: 'ETH', }, nativeWrappedTokenInfo: { chainId: 11155111, contractAddress: '0xfFf9976782d46CC05630D1f6eBAb18b2324d6B14', decimals: 18, symbol: 'WETH', name: 'Wrapped ETH', }, }, }, },

===========

This is Trade method:

public tradeInfo( chainId: number, amount: number, fromTokenContractAddress: string, toTokenContractAddress: string, ethereumAddress: string, network: NetworkInterface, tradeDirection: TradeDirection = TradeDirection.input, ): Observable { return new Observable((subscriber: Subscriber) => { (async () => { try { let uniswapPair: UniswapPair;

      if (network?.customChain) {
        uniswapPair = new UniswapPair({
          fromTokenContractAddress,
          toTokenContractAddress,
          ethereumAddress,
          ethereumProvider: this.walletConnectService.walletProvider,
          settings: new UniswapPairSettings({
            slippage: 0.005,
            deadlineMinutes: 20,
            disableMultihops: false,
            uniswapVersions: [UniswapVersion.v3],
            cloneUniswapContractDetails: network.customChain.cloneUniswapContractDetails,
            customNetwork: network.customChain.customNetwork,
          }),
        });
      } else {
        uniswapPair = new UniswapPair({
          fromTokenContractAddress,
          toTokenContractAddress,
          ethereumAddress,
          chainId,
          settings: new UniswapPairSettings({
            slippage: 0.005,
            deadlineMinutes: 20,
            disableMultihops: false,
            uniswapVersions: [UniswapVersion.v2, UniswapVersion.v3],
          }),
        });
      }

      uniswapPair.createFactory()
        .then((factory) => factory.trade(amount.toString(), tradeDirection).catch((error) => {
          console.log(error);
          subscriber.error(error);
          return undefined;
        })).catch((error) => {
          console.log(error);
          subscriber.error(error);
          return undefined;
        })
        .then((trade) => {
          subscriber.next(trade);
          if (trade) {
            trade.destroy();
          }
        })
        .catch((error) => {
          console.log(error);
          subscriber.error(error);
        });
    } catch (error) {
      console.log(error);
      subscriber.error(new Error('errors.contract_error'));
    }
  })();
});
