@elias-orijtech, this is a good replacement of

cosmos-sdk/crypto/ledger/ledger_secp256k1.go

Line 228 in 44fbb0d

if sModNScalar.IsOverHalfOrder() {

right?

[elias-orijtech]

Functionally, yes. ecdsa.IsSNormalized calls big.Int.Cmp which is not constant time. secp256k1.ModNScalar.IsOverHalfOrder is designed to be constant time.
