Is @solana/kit compatible with Anchor?

Currently, Anchor primarily supports web3.js v1. If your project is heavily dependent on Anchor, it is recommended to use a hybrid approach with @solana/compat or wait for official Anchor Kit support.

What are the performance benefits of @solana/kit?

Kit offers approximately 26% smaller bundle sizes, 10x faster cryptographic operations, and roughly 200ms faster transaction confirmation latency compared to v1.

What is @solana/compat used for?

It is a utility library that allows you to convert types between the legacy SDK (like PublicKey) and the new SDK (like Address), enabling a gradual, feature-by-feature migration.

Why does @solana/kit use BigInt?

To avoid precision issues with large numbers (like lamport amounts), Kit uses native JavaScript BigInts instead of the old BN.js or number types used in v1.

How does transaction building change in @solana/kit?

Kit moves away from the class-based 'new Transaction()' approach toward a functional approach using 'pipe()' and individual instruction functions, leading to better tree-shaking.

Learning & Documentation

Guides developers through migrating Solana applications from legacy web3.js v1 to the modern, high-performance @solana/kit SDK.

The Solana Kit Migration Assistant is a specialized tool designed to help developers navigate the transition from @solana/web3.js (v1.x) to the modern @solana/kit. It provides automated codebase analysis to detect migration blockers like Anchor dependencies, offers comprehensive API mappings for RPC calls and transaction building, and explains how to implement modern patterns like functional composition and native BigInt. Whether you are aiming for smaller bundle sizes, faster transaction confirmation, or better type safety, this skill provides the architectural guidance and code snippets necessary for a smooth transition.
