@newton-xyz/policy-pack-blockaid

Gates vault deposits at transaction-submission time using Blockaid's EVM transaction scan (validation + simulation) to catch malicious calldata, frontend-redirect attacks, and value-skim simulations

Typed TypeScript bindings for the Newton blockaid policy pack. Generated from the AVS-side artifacts at /blockaid/ in this repo.

Install

pnpm add @newton-xyz/policy-pack-blockaid

Regeneration

The generated src/* files (everything except pack.ts and prepare-query.ts) are emitted from the upstream JSON schemas. Edit the schemas under /blockaid/ and run pnpm gen:bindings from the repo root to regenerate.

The hand-written files, package.json, tsconfig.json, tsup.config.ts, and this README survive regen — you can hand-tune them.
