## The second param of listsinceblock

From [issue 8752](https://github.com/bitcoin/bitcoin/issues/8752#issuecomment-247988691)

> The second parameter (target confirmation) is quite strange and should probably be better > documented in the RPC help of listsinceblock (check original comment: #199 (comment))

From the actual docs here is it is:

> target-confirmations:    (numeric, optional) The confirmations required, must be 1 or more

However, that's misleading at best. I've seen at least one project thinking that `target-confirmations` means "filter to only show transactions of n target-confirmations". It's a weird param but I'd document it as

> target-confirmations: (numeric, optional) Return the hash of the block that has target-confirmations of confirmations, for use in a further call to listsinceblock
## Transactions confirmations

Says:

> "confirmations": n,       (numeric) The number of confirmations for the transaction. Available for 'send' and 'receive' category of transactions.

It should also say when it's < 0, it means the transaction conflicted that many blocks ago
## bip125-replaceable

There's an undocumented field of transactions "bip125-replaceable" which I believe has three possibilities "yes" "no" and "unknown"  (under what circumstances it says unknown, should also be documented)

overrideEstimatedFeerate = true;
        }
      }
    }
    
    CMutableTransaction tx;
    if (!DecodeHexTx(tx, request.params[0].get_str(), true))
        throw JSONRPCError(RPC_DESERIALIZATION_ERROR, "TX decode failed");
    if (tx.vout.size() == 0)
        throw JSONRPCError(RPC_INVALID_PARAMETER, "TX must have at least one output");
    if (changePosition != -1 && (changePosition < 0 || (unsigned int)changePosition > tx.vout.size()))
        throw JSONRPCError(RPC_INVALID_PARAMETER, "changePosition out of bounds");
    CAmount nFeeOut;
    string strFailReason;
    if(!pwalletMain->FundTransaction(tx, nFeeOut, overrideEstimatedFeerate, feeRate, changePosition, strFailReason, includeWatching, lockUnspents, changeAddress))
        throw JSONRPCError(RPC_INTERNAL_ERROR, strFailReason);
    UniValue result(UniValue::VOBJ);
    result.push_back(Pair("hex", EncodeHexTx(tx)));
    result.push_back(Pair("changepos", changePosition));
    result.push_back(Pair("fee", ValueFromAmount(nFeeOut)));
    return result;
