- BIP-44 standard: `m/44'/60'/0'/0/x` where x is the account index.

BIP-44 standard: m/44'/60'/0'/0/x where x is the account index.

44 = BIP-44 purpose, 60 = Ethereum coin type (Bitcoin=0), 0 = default account group, x = address index.

Ensures Bitcoin and Ethereum keys never overlap even from the same seed.

"Add Account" in Metamask simply increments x (0→1→2→...) — regenerates deterministically, no new randomness.
