Agents are the easiest MEV prey
Agents are the easiest MEV prey: predictable, public-mempool, a measured ~$50M/quarter tax. A sandwich only pays when a trade moves the pool enough to front-run (size vs pool depth). This returns an exposure read (low/elevated/high) and a protected-execution plan: a tight min-out, private/off-mempool inclusion (a Cobalt validity tx via validity-build), and splitting a large order into unattackable chunks. Pass tokenOut + amountUsd. Not financial advice.
