How post-quantum bundlers interact with Maximal Extractable Value (MEV) searchers, block builders, and private relays.
Because UserOperations represent high-value user intents (DEX swaps, NFT purchases, collateral liquidations), they attract the attention of MEV searchers looking to execute arbitrage, liquidations, or front-running sandwich attacks.
PQCAA bundlers bypass the public P2P mempool when processing sensitive user transactions, routing bundles directly to verified block builders via private RPC endpoints. This architectural routing eliminates front-running and returns MEV searcher rebates directly to the wallet user.
Implementing cryptographic fair sequencing protocols: using verifiable delay encryption so that transactions cannot be inspected or reordered by block builders until block execution begins.
