How we verify RPC provider pricing: sources, dates and a 45-day freshness rule
A vendor comparing itself with competitors has every reason to be wrong in its own favor. These are the rules that make our comparison tables checkable — and the rules that keep them from quietly going out of date.
Priority fees on Solana vs Ethereum, Base and Polygon: same word, different auctions
A "priority fee" is a bid in every system that uses the word, but what it bids for, who receives it and how you should estimate it differ per chain — and on one chain it buys nothing at all.
Sizing an RPC plan from your workload: sustained RPS, burst and heavy-method buckets
A request-per-second plan is sized differently from a credit plan. How to measure a workload, how a token bucket with 2× burst actually behaves, and a worked Solana indexer that lands on a specific tier.
What a Solana DAS API workload really costs: per-call credits vs flat plans
DAS calls are the most expensive reads on credit-metered Solana plans. One workload priced three ways, with every unit price sourced and dated, and the break-even point where the cheapest model changes.
SSE vs WebSocket vs gRPC: choosing a transport for blockchain data
Three ways to receive a push from a blockchain node, compared on what they actually guarantee — direction, framing, auth, resume and filtering — with one real chain for each.
TRON USDT transfer history via JSON-RPC: logs, block windows and address formats
How to rebuild an address's USDT-TRC20 history from raw event logs without a third-party indexer: which filter to send, why every request covers at most 100 blocks, how to convert TRON addresses into topics, and what a year of history costs in requests.
Watching incoming payments on Solana, Ethereum, Stellar and TON: one task, four designs
Detecting a deposit looks like the same feature on every chain. It is four different designs: an account subscription, a log subscription with a blind spot, a stream that only says when to look, and a poll.
Yellowstone gRPC filters in practice, and the same filter set over a WebSocket bridge
A Yellowstone subscription is one request describing everything you want. How its fields combine, what happens when you change it, and how to split a workload across a fixed number of streams.
