Crate solana_clmm_raydium 

Pure-Rust, no-RPC swap math for the Raydium concentrated-liquidity AMM (CLMM) on Solana.

This crate contains the deterministic integer arithmetic that the on-chain Raydium CLMM program executes — extracted unchanged into a library that has no dependency on anchor-lang, solana-program, the Solana runtime, or the Anchor account model. Given pre-decoded pool state and tick-array data, every function here is a pure function of its inputs.

Scope

• Tick ↔ sqrt-price conversions (get_sqrt_price_at_tick, get_tick_at_sqrt_price)
• Liquidity ↔ token-amount conversions (get_liquidity_from_amounts, get_delta_amounts_signed, …)
• Single-tick swap step (compute_swap_step)
• Multi-tick swap orchestration (compute_swap_full)
• Tick-array bitmap navigation (next_initialized_tick_array_start_index)
• Token-2022 transfer-fee math (calculate_fee, apply_transfer_fee, reverse_apply_transfer_fee) — mirrors spl_token_2022_interface::extension::transfer_fee byte-exactly

Out of scope

• Pool / tick-array account decoding (this crate takes pre-decoded state; caller flattens decoded TickArrayStates into the InitializedTick slice that compute_swap_full consumes)
• Token-2022 mint-extension TLV decoding and transfer-hook execution (caller resolves the active TransferFee and CPIs hook programs)
• Position fee and reward accumulation beyond liquidity_from_amounts

Provenance

Math is extracted from raydium-io/raydium-clmm/programs/amm/src/libraries/. The arithmetic itself is byte-for-byte identical to the on-chain implementation; the only changes are import paths, an internal ErrorCode enum that replaces anchor_lang::error::Error, and free-function rehosting of three static methods that used no struct fields.

state_helpers

Pure-arithmetic helpers that the upstream Raydium program defines as static methods on TickState / TickArrayState. The methods use no struct fields, so we re-host them as free functions here.

swap_full

Multi-tick swap orchestrator.
