+# Rate Limiter Feature
+
+## Overview
+
+AnchorKit now includes a pluggable rate limiter to prevent accidental overload of anchor APIs. The rate limiter is configurable per-anchor and supports two strategies:
+
+1. **Fixed Window** - Limits requests within a fixed time window
+2. **Token Bucket** - Allows burst traffic with token-based refill
+
+## Features
+
+- ✅ Per-anchor configuration
+- ✅ Two rate limiting strategies (Fixed Window, Token Bucket)
+- ✅ Configurable limits and time windows
+- ✅ Automatic enforcement on anchor requests
+- ✅ Optional (no rate limit by default)
+
+## Usage
+
+### Configure Rate Limit
+
+Only the admin can configure rate limits for anchors:
+
+```rust
+use anchorkit::{RateLimitConfig, RateLimitStrategy};
+
+// Fixed Window: 100 requests per 60 seconds
+let config = RateLimitConfig {
+    strategy: RateLimitStrategy::FixedWindow,
+    max_requests: 100,
+    window_seconds: 60,
+    refill_rate: 0, // Not used for fixed window
+};
+
+client.configure_rate_limit(&anchor, &config);
+```
+
+### Token Bucket Strategy
+
+```rust
+// Token Bucket: 50 tokens, refill 1 token per second
+let config = RateLimitConfig {
+    strategy: RateLimitStrategy::TokenBucket,
+    max_requests: 50,      // Maximum tokens
+    window_seconds: 0,     // Not used for token bucket
+    refill_rate: 1,        // Tokens per second
+};
+
+client.configure_rate_limit(&anchor, &config);
+```
+
+### Query Rate Limit Configuration
+
+```rust
+let config = client.get_rate_limit_config(&anchor);
+if let Some(cfg) = config {
+    println!("Max requests: {}", cfg.max_requests);
+    println!("Strategy: {:?}", cfg.strategy);
+}
+```
+
+## How It Works
+
+### Fixed Window
+
+- Tracks number of requests within a time window
+- Resets counter when window expires
+- Simple and predictable
+- May allow burst at window boundaries
+
+Example: 100 requests per 60 seconds
+- Request 1-100: ✅ Allowed
+- Request 101: ❌ Rate limit exceeded
+- After 60 seconds: Counter resets to 0
+
+### Token Bucket
+
+- Maintains a bucket of tokens
+- Each request consumes 1 token
+- Tokens refill at configured rate
+- Allows controlled bursts
+
+Example: 50 tokens, refill 1/second
+- Start with 50 tokens
+- Request 1-50: ✅ Allowed (consumes all tokens)
+- Request 51: ❌ Rate limit exceeded
+- After 10 seconds: 10 tokens refilled
+- Request 52-61: ✅ Allowed (10 tokens available)
+
+## Automatic Enforcement
+
+Rate limiting is automatically enforced on:
+- `submit_quote()` - Quote submissions from anchors
+
+When rate limit is exceeded, the operation returns `Error::RateLimitExceeded`.
+
+## Configuration Examples
+
+### Conservative Anchor (Low Traffic)
+```rust
+RateLimitConfig {
+    strategy: RateLimitStrategy::FixedWindow,
+    max_requests: 10,
+    window_seconds: 60,
+    refill_rate: 0,
+}
+```
+
+### High-Volume Anchor
+```rust
+RateLimitConfig {
+    strategy: RateLimitStrategy::TokenBucket,
+    max_requests: 1000,
+    window_seconds: 0,
+    refill_rate: 10, // 10 tokens/second = 600/minute
+}
+```
+
+### Burst-Tolerant Configuration
+```rust
+RateLimitConfig {
+    strategy: RateLimitStrategy::TokenBucket,
+    max_requests: 100,  // Allow burst of 100
+    window_seconds: 0,
+    refill_rate: 5,     // Steady rate of 5/second
+}
+```
+
+## Error Handling
+
+```rust
+match client.try_submit_quote(&anchor, ...) {
+    Ok(quote_id) => {
+        println!("Quote submitted: {}", quote_id);
+    }
+    Err(Ok(Error::RateLimitExceeded)) => {
+        println!("Rate limit exceeded, retry later");
+    }
+    Err(e) => {
+        println!("Other error: {:?}", e);
+    }
+}
+```
+
+## Storage
+
+Rate limit state is stored in temporary storage with 1-day TTL:
+- Lightweight and efficient
+- Automatically expires
+- Per-anchor isolation
+
+Configuration is stored in persistent storage (90-day TTL).
+
+## Best Practices
+
+1. **Start Conservative** - Begin with lower limits and increase as needed
+2. **Monitor Usage** - Track rate limit errors to tune configuration
+3. **Per-Anchor Tuning** - Different anchors may need different limits
+4. **Token Bucket for APIs** - Better for real-world API usage patterns
+5. **Fixed Window for Simplicity** - Easier to reason about and predict
+
+## API Reference
+
+### Types
+
+```rust
+pub enum RateLimitStrategy {
+    FixedWindow,
+    TokenBucket,
+}
+
+pub struct RateLimitConfig {
+    pub strategy: RateLimitStrategy,
+    pub max_requests: u32,
+    pub window_seconds: u64,
+    pub refill_rate: u32,
+}
+```
+
+### Contract Methods
+
+```rust
+// Configure rate limit (admin only)
+pub fn configure_rate_limit(
+    env: Env,
+    anchor: Address,
+    config: RateLimitConfig,
+) -> Result<(), Error>
+
+// Get rate limit configuration
+pub fn get_rate_limit_config(
+    env: Env,
+    anchor: Address,
+) -> Option<RateLimitConfig>
+```
+
+### Errors
+
+- `Error::RateLimitExceeded` (48) - Rate limit exceeded for anchor
+- `Error::InvalidConfig` (25) - Invalid rate limit configuration
+- `Error::AttestorNotRegistered` (5) - Anchor not registered
+
+## Implementation Details
+
+- Rate limiter uses temporary storage for state tracking
+- State includes request count, window start, tokens, and last refill time
+- Automatic cleanup via TTL (no manual maintenance needed)
+- Zero overhead when no rate limit is configured
+- Thread-safe (Soroban contract execution model)
+
+## Testing
+
+The rate limiter includes comprehensive tests:
+- Fixed window enforcement
+- Token bucket refill logic
+- Per-anchor isolation
+- No rate limit (unlimited) behavior
+
+Run tests:
+```bash
+cargo test rate_limiter_tests
+```
+
+## Future Enhancements
+
+Potential future improvements:
+- Sliding window algorithm
+- Distributed rate limiting
+- Rate limit metrics and monitoring
+- Dynamic rate adjustment based on load
+- Per-operation rate limits (not just per-anchor)

+## API Methods
+
+```rust
+// Configure rate limit (admin only)
+pub fn configure_rate_limit(
+    env: Env,
+    anchor: Address,
+    config: RateLimitConfig,
+) -> Result<(), Error>
+
+// Get rate limit configuration
+pub fn get_rate_limit_config(
+    env: Env,
+    anchor: Address,
+) -> Option<RateLimitConfig>
+```
+
+## Usage Example
+
+```rust

+let config = RateLimitConfig {
+    strategy: RateLimitStrategy::FixedWindow,
+    max_requests: 100,
+    window_seconds: 60,
+    refill_rate: 0,
+};
+client.configure_rate_limit(&anchor, &config);
+
+// Configure token bucket: 50 tokens, refill 1/second
+let config = RateLimitConfig {
+    strategy: RateLimitStrategy::TokenBucket,
+    max_requests: 50,
+    window_seconds: 0,
+    refill_rate: 1,
+};
+client.configure_rate_limit(&anchor, &config);
