Anchor is a framework for writing and testing Solana programs, aka smart contracts on Solana. It contains several functionalities such as:
- Rust crates and eDSL for writing Solana programs
- Interface description language (IDL) specification
- Typescript package for generating clients from IDL
- CLI and workspace management
Developers have a similar experience developing in the Anchor framework on Solana as they would using Ethereum’s Truffle.
