## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 10, release rhythm 40, longevity 100
- inputs: {"age_days": 2287, "days_push": 540, "days_rel": 651, "gap_med": 0, "n_releases_24m": 34}
- flags: archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
The Solana Program Library (SPL) is a collection of on-chain programs for Solana's Sealevel runtime, including token, associated-token-account, and governance programs. The repository has been archived and its programs migrated to separate repos under the solana-program organization.

## Use cases
- deploy SPL token programs on Solana
- implement fungible and non-fungible tokens on Solana
- build Solana smart contracts in Rust
- set up associated token accounts
- run on-chain governance programs
- find reference implementations of Solana programs

## When to choose
- you need reference implementations of classic SPL programs
- you want to fork archived Solana program code
- you need documentation on how SPL programs worked

## When to avoid
- you want actively maintained versions of SPL programs - use the solana-program organization repos instead
- you are starting a new Solana project and expect updates from this repo
- you need governance program development - it moved to a separate repository

## Facets
- artifact type: library
- maturity: maintenance
- function: blockchain, sdk, developer-tools
- domain: blockchain, developer-tools
- platform: rust, cross-platform
- tags: solana, smart-contracts, spl, on-chain-programs, token, archived-repo, cryptocurrency
