Proposal: Canton Validator Traffic & Fee Operations Toolkit

Abstract

The Canton Validator Traffic & Fee Operations Toolkit is an open-source (Apache-2.0) suite of libraries, a daemon, a CLI, and a reference dashboard that gives every Canton validator and Super Validator (SV) operator the missing economic operations layer: real-bytes traffic accounting via JSON Ledger API v2 costEstimation, per-action traffic averaging, round-aware fee calculation using live AmuletRules.extraTrafficPrice, automated traffic top-up via the traffic-purchase choice, traffic state monitoring, and round/SV-scan health diagnostics. Generalized from internal tooling already operating Askardex's Canton-mainnet Wallet and Bridge services (6+ months in production), this proposal lowers the operational TCO for every validator on Canton and provides a canonical reference for traffic estimation against the new JSON Ledger API v2.
