description: >-
  Entity-relationship graph derived from the Solana JSON-RPC method surface and its response
  schemas. Solana is not a REST resource API, so entities are the on-chain domain objects the
  RPC methods read/write (accounts, transactions, blocks, tokens, cluster state) and the
  relationships are the reference fields that link them (pubkeys, signatures, slots, mints).
entities:
  - name: Account
    key: pubkey (base-58, 32 bytes)
    read_via: [getAccountInfo, getMultipleAccounts, getBalance, getProgramAccounts, getLargestAccounts]
    fields: [lamports, owner, data, executable, rentEpoch]
    relationships:
      - belongs_to: Program
        via: owner
      - has_many: Transaction
        via: signatures for address (getSignaturesForAddress)
