@subsquid/borsh package allows to easily define fast and type-safe codec for any Solana data structure.

In the future we plan to develop robust code generation tools, that would allow to create all relevant definitions from IDL files automatically.

Meanwhile, abi module gives an example of how that might look like.

Solana support is in beta.

In particular, we expect to make Subsquid Network data ingestion at least 50 times faster.
