Bug: LND only recommends one routing hint to receive payments (+ has issues receiving on ACINQ channel)

Understanding the Issue with LND Routing Hints

When it comes to receiving payments on the Lightning Network, having multiple routing hints can be beneficial in ensuring that funds are delivered efficiently. However, a bug in the LND implementation only recommends one routing hint, which can lead to issues in receiving payments, especially when using an ACINQ channel with plenty of incoming liquidity.

The Importance of Multiple Routing Hints

In the context of the Lightning Network, routing hints are used to determine the best path for a payment to be sent. By specifying multiple routing hints, users can increase the chances of successful payment delivery, even in cases where there are network congestion or other issues. This is particularly important for users who rely on the Lightning Network for their business or personal transactions.

The Current Limitation in LND

Unfortunately, the current implementation of LND only recommends one routing hint, which can lead to issues in receiving payments. This limitation is not unique to LND, as other implementations, such as LDK, can specify up to three unique counterparties. However, the LND team has confirmed that users can manually specify multiple routing hints, which can serve as a partial workaround for this issue.

The Issue with ACINQ Channels

One of the most puzzling aspects of this issue is the difficulty in receiving payments on ACINQ channels, even when there is plenty of incoming liquidity. ACINQ channels are designed to provide a high level of liquidity and efficiency, making them an attractive option for users who need to send and receive large amounts of funds. However, the current limitation in LND can lead to issues in receiving payments on these channels, which can be frustrating for users who rely on them.

Contacting the LND Team

In an effort to resolve this issue, I contacted the LND team to report the problem and seek their assistance. However, so far, there has been no mention of a bug or any plans to address this issue. While the LND team has confirmed that users can manually specify multiple routing hints, this is not a long-term solution and does not address the underlying issue.

A Partial Workaround

While the LND team has not acknowledged a bug, adding multiple routing hints can serve as a partial workaround for this issue. By specifying multiple routing hints, users can increase the chances of successful payment delivery, even in cases where there are network congestion or other issues. However, this is not a substitute for a proper fix, and users should continue to report this issue to the LND team.

The Need for a Proper Fix

The current limitation in LND only recommending one routing hint is a significant issue that needs to be addressed. By specifying multiple routing hints, users can increase the chances of successful payment delivery, even in cases where there are network congestion or other issues. A proper fix would involve updating the LND implementation to recommend multiple routing hints, which would provide a more efficient and reliable payment experience for users.

Conclusion

In conclusion, the bug in LND only recommending one routing hint is a significant issue that needs to be addressed. While adding multiple routing hints can serve as a partial workaround, a proper fix is necessary to provide a more efficient and reliable payment experience for users. By working together, the Lightning Network community can ensure that users have access to the best possible payment experience, even in cases where there are network congestion or other issues.
