Implementation guides for Solana traders and bot builders. Copy-paste code, real benchmarks, and architecture patterns that work in production.
Why sendTransaction Needs Its Own Quota Bucket on Solana (And What Happens When It Doesn't)
During a market spike your scanner's read path and your submit path share the same credit pool. The scanner wins, the submit path returns 429, and you watch the opportunity pass. Here's why Subglow isolates sendTransaction in its own daily bucket and what that buys you.
Why Archival JSON-RPC Methods Are Dedicated-Only on Subglow (And the Full Allowlist)
Not every JSON-RPC method is equal. A single unfiltered getProgramAccounts scan can silently degrade every other customer's p50. Here's the full Subglow method allowlist, which methods are gated, and the concrete reasoning behind the policy.
Migrating From Helius to Subglow JSON-RPC: A One-URL-Change Walkthrough
If you're already running against a Helius JSON-RPC endpoint on Solana, switching to Subglow is a URL change. Here's the concrete migration: headers, auth, method compatibility, what's on parity, and what to test before you flip traffic.
Flat JSON-RPC Pricing vs Credit Metering: The Hidden Cost of "Compute Units" on Solana
Every major Solana RPC provider prices through credit or compute-unit metering, where methods have different weights and your bill scales with market volatility. Here's the math on why flat daily caps are predictable — and where credit metering quietly overcharges.
Pump.fun Graduation Detection: Catching the Raydium Migration in Real Time
Every profitable Pump.fun token eventually graduates to Raydium. This guide explains how the migration fires on-chain, how to detect it via gRPC, and how to handle the 30-second window when liquidity moves.
Why Subglow Bundles JSON-RPC With gRPC (And Why sendTransaction Lives In Its Own Bucket)
Subglow used to be a gRPC specialist. After the first wave of customer feedback, we added a flat-priced JSON-RPC endpoint on the same API key and a dedicated sendTransaction bucket. Here's the product reasoning — and what it means for your bill.
A Latency Budget for a Profitable Solana Copy-Trading Bot (Slot → Bundle in 400ms)
Where milliseconds actually go in a Solana copy-trade bot, stage by stage. A concrete latency budget with measured p50/p99 numbers for gRPC ingest, strategy eval, signing, and Jito submission.
How We Run a Solana gRPC Business at $99/mo Flat (With Real Numbers)
Why Subglow prices flat instead of credit-metered, and what it actually costs us per customer. A transparent post on the unit economics of filtered Yellowstone gRPC at $99–$249/mo.
How Subglow's Copy Trader Works: Non-Custodial Mirror Trading on Solana (2026)
A deep dive into the architecture of Subglow's non-custodial Solana copy trader — how we detect KOL trades on gRPC, stay non-custodial with on-browser private keys, and hit sub-400ms slot-to-signed-bundle latency.
