Crate arch_token_metadata_sdk 

Arch Token Metadata – Rust SDK (client-side helpers)

This crate provides:

• PDA helpers for core metadata and attributes accounts
• Instruction builders with correct account ordering and client-side validation
• Transaction builders for common flows (compose Vec)

The builders mirror the on-chain program invariants documented in docs/SECURITY.md. Signers, recent blockhashes, and submission are left to the caller.
