Base Token Batch Screen

□ No challenge detected

Base token BATCH sell check: up to 10 token addresses in one call and one payment. For each token it simulates a small buy and an immediate sell inside eth_call (no trade is sent) and returns buy tax, sell tax, round-trip loss, flags and a plain summary; a token it cannot simulate is returned as not_simulated with the reason. Built for bots that screen many new tokens: $0.03 for up to 10 (single check: $0.005). Facts, not advice.
