jupiter-sdk-amm

Scale AMM adapter crate for Jupiter's jupiter-amm-interface.

What This Implements

• ScaleAmm implementing jupiter_amm_interface::Amm.
• Offline quote logic matching Scale on-chain math for:
  • Constant product
  • Exponential
  • Buy path (mint_a -> mint_b) with fee on input mint_a
  • Sell path (mint_b -> mint_a) with fee on output mint_a
• ExactIn support and explicit ExactOut rejection.
• Dynamic account metas including beneficiary token accounts.
• PDA/ATA derivation for:
  • Config PDA: ["config"]
  • Vault PDA: [pool, mint]
  • Fee token ATA for platform + beneficiaries on mint_a

Swap Leg Selection

By default, this adapter emits Swap::TokenSwap.

You can override per market using KeyedAccount.params:

{ "swap": "gamma" }

Supported overrides:

• token_swap
• gamma
• meteora_damm_v2
• obsidian
• raydium_v2

Jupiter must confirm the final swap leg contract on their side.
