Everything you need to deploy, configure, and extend SKEP3 — the local-first Web3 security protocol.

Introduction to SKEP3

SKEP3 is a local-first, AI-powered blockchain security protocol designed to protect crypto wallets from drainers, honeypots, rug pulls, and novel exploit vectors before a single transaction hits the chain.

What is SKEP3?

Unlike cloud-based security solutions (Blowfish, Pocket Universe), SKEP3 runs entirely on your infrastructure. It intercepts outgoing transactions, forks the EVM state locally, simulates the full execution, and produces an AI-generated plain-English risk report — all within milliseconds and all within your network boundary.

How it works

  1. 01
    Intercept: SKEP3 proxy sits between your wallet and the RPC endpoint.
  2. 02
    Fork: A local Anvil fork of the mainnet is created at the current block.
  3. 03
    Simulate: The pending tx is replayed against the fork to compute exact token deltas.
  4. 04
    Analyse: On-device LLM scores the simulation output for risk using threat signatures.
  5. 05
    Respond: SKEP3 returns allow/block/warn + human-readable explanation to the UI.

Architecture overview

SKEP3 is composed of three core modules that work in concert:

Proxy Engine
Intercepts JSON-RPC calls from your wallet
EVM Simulator
Forks mainnet and replays txs locally via Foundry
AI Core
On-device LLM threat classification
