Ludo

Ludo builds a cross chain reputation layer: an address receives a score modelled on page ranking, fed by interaction history, asset composition, the quality of projects it supports and social signals, and emitted as a value contracts can read. A user can mint reputation as a soulbound NFT, and projects filter for genuine users by score, keeping bots and wash addresses off a list.

It targets sybil addresses flooding growth campaigns, replacing one time verification with continuous behavioural scoring, where the score moves with activity and wash trading dilutes it. Coverage of more than 18 blockchains, the REST and GraphQL endpoints offered, and the contract and holder assessment run daily on tens of thousands of new projects are all checkable. The score is not a black box: each dimension is broken out on a detail page so a user sees what moved it, and the scoring endpoint is billed by call volume.
