This page summarizes the `amm` program and the `damm-v1-sdk` account helpers. For exact generated layouts, use the bundled IDL and TypeScript types exported by `@meteora-ag/dynamic-amm-sdk`. ## PDA Map DAMM v1 sorts token mint public keys lexicographically for permissionless pool PDAs. The helpers call the larger key `first` and the smaller key `second`. | Account | SDK or Rust helper | Seeds | | - | - | - | | Permissionless pool | `derivePoolAddress(...)`, `derive_permissionless_pool_key` | curve type byte, sorted mints | | Permissionless pool with fee tier | `derivePoolAddress(...)`, `derive_permissionless_pool_key_with_fee_tier` | curve type byte, sorted mints, optional little-endian trade-fee bps | | Config-based constant-product pool | `derivePoolAddressWithConfig(...)`, `derive_permissionless_constant_product_pool_with_config_key` | sorted mints, config | | Customizable constant-product pool | `deriveCustomizablePermissionlessConstantProductPoolAddress(...)`, `derive_customizable_permissionless_constant_product_pool_key` | `pool`, sorted mints | | Config | `deriveConfigPda(index, programId)` | `config`, little-endian `u64` index | | LP mint | `derive_lp_mint_key(pool)` | `lp_mint`, pool | | Vault A/B LP token account | `derive_vault_lp_key(vault, pool)` | vault, pool | | Protocol fee token account | `deriveProtocolTokenFee(pool, mint, programId)` | `fee`, token mint, pool | | Lock escrow | `deriveLockEscrowPda(pool, owner, programId)` | `lock_escrow`, pool, owner | | Operator | source helper | `operator`, whitelisted address | | LP mint metadata | `deriveMintMetadata(lpMint)` | Metaplex `metadata`, metadata program, LP mint | Permissioned pools use an arbitrary signer account for the pool address rather than a pool PDA. ## Constants | Constant | Value | Use | | - | - | - | | `PROGRAM_ID` | `Eo7WjKq67rjJQSZxS6z3YkapzY3eMj6Xy8X5EQVn5UaB` | Deployed DAMM v1 program. | | `STAGING_PROGRAM_ID` | `ammbh4CQztZ6txJ8AaQgPsWjd6o7GhmvopS2JAo5bCB` | Staging program compiled behind the staging feature. | | `FEE_DENOMINATOR` | `100_000` | Trade, protocol, host, and partner fee denominator. | | `MAX_FEE_BPS` | `1500` | Max trade fee for program validation, equal to 15%. | | `MEME_MIN_FEE_BPS` / `MEME_MAX_FEE_BPS` | `25` / `1500` | Customizable pool fee bounds, equal to 0.25% through 15%. | | `FEE_NUMERATOR_DIVISIBLE_FACTOR` | `50` | Customizable fee numerator must be divisible by 50. | | `MAX_PARTNER_FEE_NUMERATOR` | `50_000` | Max partner share of protocol fee, equal to 50%. | | `HOST_TRADE_FEE_NUMERATOR` | `20_000` | Referral host share of protocol fee, equal to 20%. | | `PERMISSIONLESS_AMP` | `100` | Stable-pool amplification for permissionless stable pools. | | `MAX_AMP` | `10_000` | Max stable-swap amplification coefficient. | | `MIN_CHANGE_AMP_DURATION` | `600` seconds | Minimum time between stable amp updates. | | `SLOT_BUFFER` | `9000` slots | Mainnet slot-based pre-activation buffer. | | `TIME_BUFFER` | `3600` seconds | Mainnet timestamp-based pre-activation buffer. | | `MAX_ACTIVATION_SLOT_DURATION` | `SLOT_BUFFER * 24 * 31` | Max future slot activation duration. | | `MAX_ACTIVATION_TIME_DURATION` | `TIME_BUFFER * 24 * 31` | Max future timestamp activation duration. | | `QUOTE_MINTS` | SOL, USDC | Quote mints allowed for alpha-vault launch-pool paths on mainnet builds. | ## Enums | Enum | Values | | - | - | | `PoolType` | `Permissioned`, `Permissionless`. | | `ActivationType` | `0` slot, `1` timestamp. | | `CurveType` | `ConstantProduct`, `Stable { amp, token_multiplier, depeg, last_amp_updated_timestamp }`. | | `DepegType` | `None`, `Marinade`, `Lido`, `SplStake`. | | `OperatorPermission` | `0` claim protocol fee, `1` zap protocol fee. | ## Pool `Pool` is the primary DAMM v1 state account. | Field | Use | | - | - | | `lp_mint` | Pool LP token mint.
