executeQuote on testnets

[phdargen]

Summary

This is feedback from my experience integrating the Across SDK into CDP AgentKit, see coinbase/agentkit#566.

Overall good docs and the sdk.ts example script is very useful.
I encountered some edge-cases where the executeQuote method got stuck indefinitely as described below.
I think these issues should only appear for testnet transfers, but might still be useful to be aware of this.

Environment Details

• Across Integrator SDK version: 0.2.0
• Node.js version: 20.9.0
• Package manager and version: npm 10.1.0

Integration Details

• Functionality Affected:

  • Getting a quote
  • Executing a quote
  • Tracking bridge progress & step affected (approval, deposit, fill)
  • Lower-level utilities
  • Other (please specify):

Steps to Reproduce

1. Native ETH transfer from sepolia -> base-sepolia

• call executeQuote with no destinationClient or with viem default http()
  -> eth_getFilterChanges not supported, falls back to using getFillByDepositTx but this also fails because api does not support testnets (see error messages at the end below)
  -> does not throw error (even though throwOnError: true), process stuck indefinitely
• call executeQuote with destinationClient using alchemy rpc -> works as expected

2. Native ETH transfer from base-sepolia -> sepolia

• call executeQuote with no destinationClient or with viem default http()
  -> deposit successfull, no errors/warnings but Tx never gets filled -> process stuck indefinitely
  -> seems this route never gets filled, probably shouldn't return a quote in this case
• example TX: depositTxId 1001057, depositTxHash 0xff194d0d9474a1dbf320ba4aba2e871eb3e8036cbdb26a71dac391d7f3c25b1f

Is This a Regression?

• Yes
• No
• Not Sure

Code Snippets (optional)

      const progress = await acrossClient.executeQuote({
        walletClient: walletClient,
        destinationClient: destinationClient,
        deposit: quote.deposit,
        onProgress: (progress) => {
          if (progress.step === "approve" && progress.status === "txSuccess") {
            const { txReceipt } = progress;
            approvalTxHash= txReceipt.transactionHash;
            console.log("approvalTxHash", approvalTxHash);
          }
          if (progress.step === "deposit" && progress.status === "txSuccess") {
            const { depositId, txReceipt } = progress;
            depositTxId = depositId;
            depositTxHash = txReceipt.transactionHash;
            console.log("depositTxId", depositTxId);
            console.log("depositTxHash", depositTxHash);
          }
          if (progress.step === "fill" && progress.status === "txSuccess") {
            const { fillTxTimestamp, txReceipt, actionSuccess } = progress;
            fillTxHash = txReceipt.transactionHash;
            success = actionSuccess;
            console.log("fillTxHash", fillTxHash);
          }
        },
        infiniteApproval: false,
        throwOnError: true,
      });
