Opportuna is a real-time cryptocurrency arbitrage platform that helps traders spot profitable price differences across 12+ exchanges - without needing API keys or coding skills.

What We Do

We monitor live price data across major exchanges including Binance, Bybit, OKX, KuCoin, and more, surfacing two types of arbitrage opportunities:

  • Spot arbitrage: buy crypto cheaper on one exchange, sell higher on another
  • Funding rate arbitrage: profit from spreads between spot and perpetual markets

Key Features

  • Real-time scanner: live price updates, not delayed or historical data
  • Smart filters: filter by exchange, profit threshold, volume, and transferability
  • No API keys required: works out of the box, no complex setup
  • Mobile-optimized: full functionality on any device
  • Free tier: full scanner access with no credit card required
  • Guest preview: browse live opportunities without signing up

Why Opportuna?

Most arbitrage tools either require API keys, limit you to a few exchanges, or show stale data. Opportuna is built for traders who want to find opportunities fast without spending hours configuring tools or manually checking exchanges

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.
