Class MaxDustHTLCExposure.FixedLimitMsat

  • Enclosing class:
    MaxDustHTLCExposure

    public static final class MaxDustHTLCExposure.FixedLimitMsat
    extends MaxDustHTLCExposure
    This sets a fixed limit on the total dust exposure in millisatoshis. Setting this too low may prevent the sending or receipt of low-value HTLCs on high-traffic nodes, however this limit is very important to prevent stealing of large amounts of dust HTLCs by miners through [fee griefing attacks](https://lists.linuxfoundation.org/pipermail/lightning-dev/2020-May/002714.html). Note that if the feerate increases significantly, without a manual increase to this maximum the channel may be unable to send/receive HTLCs between the maximum dust exposure and the new minimum value for HTLCs to be economically viable to claim.
