Module token 

TEMPORARY: backend facade for SPL Token CPI builders.

This module keeps Hopper-owned instruction semantics while execution still flows through the active backend substrate. It will be replaced by Hopper-native instruction builders once the substrate-facing builders are finalized.

Semantic CPI facades: the API is Hopper-owned (builder pattern over AccountView / Signer), while execution is delegated through Hopper’s checked CPI semantics.

Provides checked-by-default TransferChecked, MintToChecked, BurnChecked, ApproveChecked, CloseAccount, Revoke, and InitializeAccount builders. Deprecated plain Transfer/MintTo/Burn/Approve builders are compiled only when legacy-token-instructions is explicitly enabled.

Functions

require_mint_authority

Verify an SPL Mint account’s mint_authority COption field matches expected_authority.

require_mint_decimals

Verify an SPL Mint account’s decimals byte matches expected.

require_mint_freeze_authority

Verify an SPL Mint account’s freeze_authority COption field matches expected_freeze.

require_token_authority

Verify an SPL Token account’s owner field matches authority.key().

require_token_mint

Verify an SPL Token account’s mint field matches expected_mint.

require_token_owner_eq

Verify an SPL Token account’s owner field matches a pubkey supplied directly (i.e. not wrapped in an AccountView).
