  notes: >-
    Ostium is a self-custodial DeFi protocol; there is no server-side API key or
    OAuth. Authentication and authorization happen at the wallet / smart-contract
    layer. The public Builder API read endpoints (prices, OHLC, subgraph, price
    stream) require no credentials.
schemes:
- name: trader-wallet-signature
  type: wallet-signature
  description: >-
    Trader-owned positions signed directly by the trader's EOA (self + self / self +
    gasless modes). The connected trader address authorizes on-chain actions via
    wallet signatures; Safe-based gasless modes submit sponsored user operations.
  modes: [self-and-self, self-and-gasless]
- name: delegate-key
  type: delegated-key
  description: >-
    Backend-controlled delegated execution. A delegate address/EOA registered via
    setDelegate signs and (optionally) pays gas on behalf of a trader. The delegate
    private key is generated/exported from the Ostium app.
  modes: [delegated-and-self, delegated-and-gasless]
  setup_operations: [setDelegate, removeDelegate, setupGaslessDelegation]
- name: public-read
  type: none
  description: >-
    Read-only market and account data (createReadOnly mode) and the public Builder
    API endpoints require no authentication.
  modes: [read-only]
