Multi-Market Adapters

Varla's adapter architecture — how the protocol connects to different prediction market platforms through a standardized interface.

The Adapter Pattern

Each prediction market platform has its own token format, oracle source, and resolution mechanics. Varla uses adapter contracts that translate platform-specific details into a standardized interface VarlaCore understands.

Adapter architecture
Prediction Market Platform
        │
   Platform Adapter ← Translates:
   ├── Token format → Standard ERC-1155 interface
   ├── Price source → VarlaOracle-compatible feed
   ├── Resolution → Standard resolved/unresolved status
   └── Market metadata → Risk tier classification
        │
     VarlaCore ← Works with any adapter

Adding a New Platform

To integrate a new prediction market, a new adapter contract must implement the IVarlaAdapter interface. This includes methods for token validation, price fetching, and resolution status checks. The adapter is then registered with VarlaCore via governance.
