Privacy & safety

Safety limits

OVA implements multiple safety measures to prevent abuse.

Rate limits

  • 60 API requests per minute per wallet
  • 60 MCP requests per minute per API key (override with MCP_MAX_REQUESTS_PER_MINUTE)
  • Maximum 3 concurrent sessions per wallet
  • Session timeout after 15 minutes idle
  • Withdrawals: 5 distinct requests per wallet per hour, with min and max amounts

Agent step caps

Computer-use loops can burn tokens if a model gets stuck. Each session has hard caps independent of your balance:

  • Maximum 80 agent steps per session (override with SESSION_MAX_STEPS)
  • Auto-stop if the screenshot is unchanged for 4 consecutive steps (override with SESSION_STALE_SCREEN_STEPS)

Spend caps

  • Sessions stop when balance is depleted
  • Daily spend limits available (configurable)

Sandbox security

  • Isolated Docker containers
  • No access to host networks
  • Metadata endpoints blocked
  • Resource limits (CPU, memory)
  • No privileged operations

Abuse prevention

Wallets engaging in abuse may be blocked. This includes:

  • Attempting to break out of sandbox
  • Mining cryptocurrency
  • Attacking other systems
  • Generating illegal content
