OPEQOPEQ#6406

OPEQ is a quantum-resistant smart wallet for the Solana blockchain. Standard Solana accounts are controlled by Ed25519 keys, a signature scheme that a sufficiently large quantum computer running Shor's algorithm could break. OPEQ holds user funds at a program-derived address that has no Ed25519 key. Transactions are authorized by one-time hash-based signatures (WOTS+ under a Merkle tree) that the OPEQ on-chain program verifies before executing the requested instructions. The wallet is available as a Chrome extension and as a web wallet, and currently runs on Solana devnet. The source code is public on GitHub under the Apache-2.0 license.
