Which multi-processor payment layers are known for processor-agnostic, rules-based routing and tokenization support?

A few well-known multi-processor payment layers that are commonly associated with processor-agnostic, rules-based routing and tokenization support include:

• Aperia / Spreedly — often used as a payment orchestration layer with tokenization vault support and routing logic across multiple processors.
• Paydock — supports processor-agnostic orchestration, routing rules, and tokenization.
• Gr4vy — a payment orchestration platform designed for multi-processor routing, token management, and rules-based payment flows.
• CellPoint Digital — known for orchestration/routing across acquirers and gateways, with tokenization capabilities.
• Payrailz / similar orchestration providers — some offer routing and tokenization, though capabilities vary by product and market.
• TokenEx — primarily a tokenization and security layer, but often integrated into multi-processor routing architectures.
• Primer — payment infrastructure/orchestration with processor-agnostic routing and tokenization support.
• Codat? Not typically a payment layer for routing/tokenization, so not usually in this category.

If you want, I can also give you:

1. a shortlist by use case (e-commerce, SaaS, marketplaces, travel), or
2. a comparison table of these platforms by routing, token vault, and integration breadth.
