Ledger device: Missing critical parameter (0x6800) about app-xrp

[patriksletmo]

The XRP app currently requires the flag tfFullyCanonicalSig to be set when signing transactions (https://xrpl.org/transaction-common-fields.html#global-flags). It appears that your Flags field does not contain it, which would explain why the transaction fails with the error you're seeing.

This flag has been deprecated since its introduction in this app, so it probably makes sense to remove the requirement. Please let me know what you think @RareData @natenichols.

You can find the relevant code here

app-xrp/src/xrp/xrp_parse.c

Lines 423 to 432 in 066af6b

	// Reject transaction if tfFullyCanonicalSig is not set
	if (field->id == XRP_UINT32_FLAGS) {
	uint32_t value = field->data.u32;
	if ((value & TF_FULLY_CANONICAL_SIG) == 0) {
	err.err = 0x6800;
	return err;
	}
	}
	break;

I agree, enforcing tfFullyCanonicalSig is no longer necessary. Until there is a new firmware version @natenichols, increase your Flags value by the https://xrpl.org/transaction-common-fields.html#global-flags decimal value 2147483648. For example, if you intend to sign a transaction with Flags: 65536, use Flags: 2147549184 instead.

Thank you guys, I really appreciate the quick feedback.

This worked to solve the issue in the OP.
