Network Mapping

Overview

Network mapping translates between internal codes and external blockchain identifiers. A payment platform may map a user-facing network name to chain ID, RPC cluster, explorer, native fee asset, token contract, confirmation policy, and supported bridge route. Mappings are operational data, not cosmetic labels. Incorrect or stale entries can validate the wrong address, monitor an unrelated contract, or credit an unsupported token. Aliases and renamed networks make uncontrolled string matching especially risky.

Teams should maintain one versioned source of truth with ownership, review dates, and deployment environments. Changes need automated tests against known genesis data and contracts. Historical records should preserve the mapping version used at transaction time so audits remain reproducible after configurations evolve. Unknown versions, ambiguous aliases, unsupported fields, duplicate records, and stale configurations should fail into review rather than being silently mapped to a convenient default. Inputs to Network Mapping need explicit validation and deterministic failure behavior.

Changes to Network Mapping should pass automated tests against known network identifiers, contracts, encodings, and expected outputs. Rollout needs environment separation, change approval, rollback, and historical traceability so past transactions can be interpreted using the configuration active at that time.

This evidence helps distinguish incorrect configuration from an upstream node, protocol, or business-logic failure. Operational logs for Network Mapping should record the version, caller, resolved value, and downstream action without exposing secrets. Network Mapping should be maintained through one versioned source of truth that defines identifiers, schemas, allowed values, ownership, and deployment scope. Human-readable labels are not sufficient when different chains, environments, or providers reuse similar names.
