Crate winterwallet_common 

Shared constants, discriminators, domain tags, and account state layout for the WinterWallet program. Used by both the on-chain program and off-chain clients to eliminate constant drift.

Modules

discriminator

Instruction discriminator bytes matching the on-chain match arms.

Constants

ID

The const program ID.

MAX_CPI_INSTRUCTION_ACCOUNTS

Upper bound on account metas per inner CPI’d instruction inside Advance.

MAX_PASSTHROUGH_ACCOUNTS

Upper bound on trailing accounts an Advance instruction can commit to. Sizes the stack-allocated signature-preimage buffer used during recovery.

SIGNATURE_LEN

Signature byte length: (N + 2) * 32.

TOTAL_SCALARS

Total scalars including the two checksum scalars.

WALLET_ACCOUNT_LEN

On-chain WinterWallet account data length: id(32) + root(32) + bump(1).

WALLET_BUMP_OFFSET

Byte offset of the bump field in the WinterWallet account.

WALLET_ID_OFFSET

Byte offset of the id field in the WinterWallet account.

WALLET_ROOT_OFFSET

Byte offset of the root field in the WinterWallet account.

WINTERNITZ_SCALARS

Number of Winternitz message scalars (N). Total scalars = N + 2.

WINTERWALLET_ADVANCE

Domain tag for the Advance preimage.

WINTERWALLET_INITIALIZE

Domain tag for the Initialize preimage.

WINTERWALLET_SEED

PDA seed prefix.

Functions

check_id

Returns true if given address is the ID.

id

Returns the ID.
