 If the settlement does not expose any MEV (e.g. it executes all trades without AMMs) it's safe and most efficient to directly submit to the public mempool.
 However, if a settlement exposes MEV the driver would submit to an MEV-protected RPC like [MEVBlocker](https://mevblocker.io).
 
-Solvers that need parallel settlement submission can use [Solver7702Delegate](../../solvers/solver-7702-delegate.md). It keeps the existing solver EOA as the settlement caller while auxiliary EOAs provide additional nonce lanes if the main solver EOA has pending transactions.
