- [Methodology](https://www.probitylabs.ai/methodology) — How the Probity Score works: how an Ethereum wallet becomes a single signed score from −100 to +100. The engine reads dozens of on-chain signals, separating evidence that lowers reputation from evidence that raises it. The on-chain standing scale has nine fixed bands where negative scores indicate risk or illicit exposure while positive scores indicate recognised or reputable standing.
