Block50

Block50 lets you analyze and compare wallet performance over a 50-block window. Check your own landing rates, compute usage, and block inclusion — or compare your wallet against another to see how you stack up.

What You Can See

Landing rate — how many of your transactions made it into a block
Block inclusion — which blocks your transactions landed in
Compute units — your CU usage vs another wallet’s
Transaction count — how many txs each wallet had in the window
Head-to-head comparison — run your wallet against any other address over the same 50-block period

Quick Start

Fee Estimation

Returns a recommended priority fee based on current network conditions:

Level	Landing Probability	Use Case
`low`	~60%	Non-urgent, cost-sensitive
`medium`	~80%	Standard transactions
`high`	~95%	Time-sensitive operations
`very_high`	~99%	Critical (arbitrage, liquidations)

Historical Data

GET /v1/block50/history?from=284500000&to=284501000

Returns an array of Block50 snapshots for the given slot range. Useful for backtesting fee strategies and analyzing historical congestion patterns.
