​
Key Derivation

c8ntinuum uses Ethereum-compatible HD key derivation:
PropertyValue
CurveECDSA secp256k1
SDK Default HD Pathm/44'/118'/0'/0/0
Ledger Ethereum HD Pathm/44'/60'/0'/0
SDK Default Coin Type118 (Cosmos)
Ledger Ethereum Coin Type60 (Ethereum)
Key Typeeth_secp256k1
c8ntinuum supports eth_secp256k1 account keys. Ledger coin type 60 uses the Ethereum app and creates an eth_secp256k1 public key; Ledger coin type 118 uses the Cosmos app and creates a Cosmos secp256k1 public key.
