4.1 Chain Choice: Solana

Fast finality and low-friction participation for membership and rewards

RH is deployed on Solana to support a smooth, low-friction experience for recurring on-chain actions. The protocol’s core flows—locking RH, evaluating tier eligibility at snapshot checkpoints, and distributing rewards by program rules—benefit from fast confirmations and predictable transaction costs.

Solana is selected based on the following considerations:

• Cost efficiency: Low transaction costs reduce participation friction across frequent membership actions.

• User experience: Fast finality supports responsive locking, claiming, and program interactions.

• Ecosystem adoption: Broad wallet and infrastructure support improves onboarding and accessibility.

• Operational practicality: Mature tooling and monitoring enable disciplined deployments and incident response.

This chain choice is a product and operations decision aimed at minimizing friction for users while maintaining clear, verifiable on-chain records for RH’s membership and rewards programs.
