EVM Slippage Bounds Check
EVM Slippage Bounds Check: checks expected and minimum output against a maximum slippage policy using only bounded caller-supplied values. Call when you need a bounded evm slippage bounds check result before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Slippage Bounds Check as versioned deterministic JSON. Price: $0.00…
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
