Overview
What SAID Protocol actually does.
SAID Protocol provides on-chain identity and reputation for AI agents, using Solana Program Derived Addresses (PDAs) to give each agent a verifiable, persistent identity. As autonomous agents proliferate and begin transacting with one another, knowing which counterparty you're actually dealing with becomes essential — SAID makes that verifiable rather than assumed.
On top of identity, it adds trust scoring and agent-to-agent micropayments, so agents can evaluate a counterparty's track record before transacting and then pay one another directly. That combination — identity, reputation, and payment — is the minimum viable trust stack for a real agent economy.
SAID is Solana-primary, with an ERC-8004 bridge for cross-ecosystem identity so agents aren't siloed to a single chain, and its trust-scoring functionality is already live.
For builders of agent marketplaces, multi-agent systems, and autonomous services on Solana, SAID Protocol supplies the identity, reputation, and trust primitives agents need to safely discover, vet, and pay one another — infrastructure that grows more valuable as the agent ecosystem expands.
