The Solana Winternitz Vault is a quantum-resistant lamports vault that leverages Winternitz One-Time Signatures (WOTS) for security. The vault implements a truncated Keccak256 hash, offering 224-bits of preimage resistance, which remains robust against quantum threats, including Grover's algorithm.


Security Considerations:
While PDAs themselves should be quantum resistant, if the update authority of a program deploying this contract is a keypair, your funds are still at risk.
What if a transactions One-Time Signature could be reversed and redirected within the 400-millisecond block time.(Using a quantum-computer)
