Yellowstone gRPC on Devnet

The Problem

Currently, developers must use standard WebSocket for devnet development, then switch to Yellowstone gRPC for mainnet. This creates a complex development workflow with inconsistent performance testing.

Why This Matters

• Unified Development: Same code from devnet to mainnet

• Better Testing: Test trading bots and real-time apps with realistic performance

• Cost Savings: Avoid expensive mainnet testing

• Faster Development: No more switching between technologies

What We Need

Enable Yellowstone gRPC Geyser plugin support on devnet for seamless development experience.

Current: WebSocket (devnet) → Yellowstone gRPC (mainnet)
Proposed: Yellowstone gRPC (devnet) → Yellowstone gRPC (mainnet)

This would make developing high-performance Solana applications much simpler and more cost-effective.
