1. What is SoulLedger?
SoulLedger is the trust layer for AI agents on Base L2. It is an open protocol that issues cryptographic SX# passports, computes 5-factor trust scores from behavioral history, and indexes 130,000+ ERC-8004 agents. It acts as the x402 trust provider, enabling agentic commerce between autonomous AI agents. Each passport is soulbound (ERC-721 non-transferable) and anchored via EAS attestations.
