I guess this issue was limited to btcd and is not present on bitcoind? |

It affects any client using btcd/wire, so it affects dex users with bitcoind. |

This updates the btcd require to v0.23.2, which includes a critical fix to the wire package's block parsing code that resolves a failure to deserialize a block with a script witness item larger than 11000. There are now blocks on mainnet and testnet that cannot be deserialized with v0.23.1, meaning this is a critical fix for takers who need to find the maker's redeem transaction and pull the block containing the spending transaction. For SPV, only the matching block is pulled. For a full node RPC wallet, the blocks are pulled in sequence and each transaction is checked directly. As such, the issue affects both types of wallet clients. See mainnet block 0000000000000000000400a35a007e223a7fb8a622dc7b5aa5eaace6824291fb containing and enormous 998-of-999 tapscript multisig in txn 7393096d97bfee8660f4100ffd61874d62f9a65de9fb6acf740c4c386990ef73. See also testnet block 0000000000000032fcf519b61aad2b966348e3f2d27687b26277933cc9881965 containing taproot transaction 44692bc2da73192cd0b89bc7a43c0ce43578f6b3567bc945e46e6952e8ec5ca5. This also updates the btcwallet require from 0.15.1 to 0.16.1. This also adds a new test with the above mainnet block and transaction as test vectors.

There are now blocks on mainnet and testnet that cannot be deserialized with v0.23.1, meaning this is a critical fix for takers who need to find the maker's redeem transaction
with compact block filters, and then pull the matching block to extract the spending transaction.either full node or SPV.See mainnet block 0000000000000000000400a35a007e223a7fb8a622dc7b5aa5eaace6824291fb containing and enormous 998-of-999 tapscript multisig in txn 7393096d97bfee8660f4100ffd61874d62f9a65de9fb6acf740c4c386990ef73.

The simnet-trade-tests are broken on master for some time now, so we'll have to rely on the test results for the backport branch (#1897).
