Decode Engine

How Prism translates XDR results into human-readable errors.

The Decode Engine is the core of Tier 1 diagnostics.

Process

1. Extraction: It takes a TransactionResult and extracts the specific error variant.
2. Classification: Categorizes the error (e.g., HostError, ContractError).
3. Enrichment: Maps the code to the Error Taxonomy.
4. Resolution: Fetches and parses WASM custom sections to resolve custom contract errors.

Performance

Designed to complete in < 2 seconds for a standard mainnet transaction.
