Wallet PQ Account Type — Zoo mirror of HIP-0085

Draft

Zoo-side mirror of Hanzo HIP-0085. Adopts the 48-byte ML-DSA-65-derived AccountID and BIP-32 path m/44'/9000'/nid'/0/n under the canonical ZOO_STRICT_PQ profile. Heavy spec lives in HIP-0085.

ZIP-0813: Wallet PQ Account Type

Abstract

ZIP-0813 mirrors Hanzo HIP-0085 into Zoo Network. The native PQ wallet account on Zoo Network is identified by a 48-byte AccountID derived as SHA3-384("LUX-ACCOUNT-V1" || mldsa_pubkey) (the cust string is shared across the strict-PQ family for byte equality). HD derivation follows the canonical Lux path m/44'/9000'/nid'/0/n, where nid' is the Zoo Network id. EVM-compat 20-byte addresses are emitted only as read-side projections.

ProfileZooStrictPQ = 0x04. Field values are byte-identical to LUX_STRICT_PQ; only the ProfileID byte distinguishes the chain.

Zoo-specific bindings

  • luxfi/wallet/pq/account.go is reused directly; one wallet binding across Lux + Zoo per ZIP-0014's "no custom extensions needed" principle.
  • Zoo ZRC-721 token-bound accounts (ZIP-0006) derive their on-chain identity from the same 48-byte AccountID; the token-id is bound into a Zoo-specific derivation index above 200.
  • KAT vectors reused from luxfi/consensus/protocol/auth/testdata/account_v1.json.

Compliance

A Zoo wallet on ZOO_STRICT_PQ MUST NOT use the 20-byte EVM-form address as the primary identifier. ZRC-20/721/1155 indexers MAY emit EVM-form addresses for backward-compatible block-explorer surfaces.
