Photon Indexer
ZK Compression · Abyss
Light Protocol's off-chain indexer that reconstructs compressed account state by parsing Solana transaction logs, since compressed data is emitted in logs rather than stored in on-chain accounts. Photon provides a gRPC and REST API for querying compressed account balances, ownership, and Merkle proofs needed to build state-transition transactions. Without Photon or an equivalent indexer, clients cannot determine current compressed state, making it essential infrastructure for any ZK Compression application.
