LastRateLimitedBlock
Storage Map v273 → v411 Changed in v411Block of last rate-limited operation by key type.
Explore chainQueried by: developers
The Big Picture
Many operations are rate-limited. This storage tracks the last block for each rate-limited operation type, enabling the chain to enforce cooldowns.
Use Cases
- Check rate limit status
- Debug rate limit errors
- Build rate-aware tooling
From Chain Metadata
============================ ==== Rate Limiting ===== ============================ MAP ( RateLimitKey ) --> Block number in which the last rate limited operation occured
Purpose & Usage
Purpose
General rate limiting tracking for various operations.
Common Query Patterns
- Query by rate limit key
Query Keys

Code Examples
// ----------------------------------------------------------------------
// HEADS UP: 1 arg below has a complex type with no usable default.
// Look for `undefined as any` and replace it with real value
// before running — the snippet compiles, but will fail at runtime as-is.
