Pool and Fee Config for Memecoin Pools

This section is under construction. More details will be added soon.

Current Fee System for Memecoin Pools

  • Dynamic Fee: For Memecoin Pools, Dynamic Fee is the % fee charged per swap. This fee is dynamic and set by the protocol, based on memecoin creator requests or market conditions.

  • Protocol Fee: Protocol Fee represents the amount of fees charged per swap that goes to the protocol or integrations that drive volume to the pool. Protocol Fee is a % of the Dynamic Fee.

How to choose a suitable Pool Config from the list?

What fee parameters to choose depends on your project's needs. You will need to look at the pool config list and choose a suitable pool_config_key with your preferred fee parameters.

If you want to create an Alpha Vault along with your new pool, you also need to find a pool_config_key that is mapped to a vault_config_key that meets your requirements.

Pool Config List

Pool Config used by Meteora

  • By default, Meteora's frontend is currently using this pool config key for Memecoin Pool creation: FiENCCbPi3rFh5pW2AJ59HC53yM32eLaCjMKxRqanKFJ

  • For the FiENCCbPi3rFh5pW2AJ59HC53yM32eLaCjMKxRqanKFJ pool config, it doesn't allow creation of any Alpha Vault, therefore it's field vault_config_key is 1111111...

  • Launchpads/Integrators may use their own custom pool config key, because they would want custom pool_creator_authority, to prevent front-running of the token launch pool.

What does each field in the Fee Config mean?

  • config_address = the pool config key

  • trade_fee_bps = pool trading fee

  • protocol_fee_bps = protocol fee charged from pool trading fee

  • activation_duration = used to determine when exactly the pool will start trading.

  • start trade time = current_time + activation_duration Or current_slot + activation_duration, depends on the activation_type

  • vault_config_key = alpha vault config key. If it is 11111111111111111111111111111111, means no alpha vault. If not, the pool can create an alpha vault. Note: This is NOT the same as the vault address.

  • pool_creator_authority = address which can use the pool config key to create a pool. If it is 11111111111111111111111111111111, it's public and available for everyone to use

  • activation_type = pool activation type. 0 = slot, 1 = time

Pool Config Example

  • Sample: https://amm-v2.meteora.ag/pool-configs

  • Sample fields: { "config_address": "FiENCCbPi3rFh5pW2AJ59HC53yM32eLaCjMKxRqanKFJ", "trade_fee_bps": 1500, "protocol_fee_bps": 2000, "activation_duration": 0, "vault_config_key": "11111111111111111111111111111111", "pool_creator_authority": "11111111111111111111111111111111", "activation_type": 0 },

User Flow Example

A pool config may or may not have an associated vault config. There's no vault config associated when the vault_config_key is 11111111111111111111111111111111

When the pool config has a vault config, user can create the pool + Alpha Vault that is binded (auto-whitelisted) by the pool. The Alpha Vault created will inherit the parameters (Pro Rata / FCFS + buying_cap, vesting duration, etc.) from the vault config.

Let's say a user wants to create the pool ABC/SOL with an Alpha Vault, the user will need to:

  1. Check for pool config that have vault_config_key not =1111..., and pool_creator_authority is the user or 1111... (accessible by the public)

  2. Based on the vault requirement the user wants, the user will need to:

    a) Check all the pool configs from step 1, which are each mapped to a vault_config_key, as well as

    b) Check for vault config and look for one that fits the requirement

  3. If the user finds a requirement that suits their needs, they can use that pool_config_key to create the pool, then use the pool config-mapped vault_config_key to create the vault. As long as vault_config_key is used, the vault is automatically whitelisted upon pool creation.

All the settings are already predefined by pool_config + its mapped vault_config_key

The permutations for pool config + Alpha vault are created by the Meteora team.

Pool Config Example

{ 
"config_address": "8aPHoLN8ke6PhWeYA7ELi19fppptVYUCQvqKWR5yP1sn", 
"trade_fee_bps": 150, 
"protocol_fee_bps": 2000, 
"activation_duration": 1512000, 
"vault_config_key": "7ixojP8Zuu4csfTycHi8ywQymHm9zxAhu1TjnFuJaq2R", 
"pool_creator_authority": "5unTfT2kssBuNvHPY6LbJfJpLqEcdMxGYLWHwShaeTLi", 
"activation_type": 0 
},

Alpha Vault Config Example

{
  "address": "7ixojP8Zuu4csfTycHi8ywQymHm9zxAhu1TjnFuJaq2R",
  "max_depositing_cap": 10,
  "start_vesting_duration": 1,
  "end_vesting_duration": 24107,
  "depositing_duration_until_last_join_point": 24107,
  "individual_depositing_cap": 1,
  "escrow_fee": 0,
  "activation_type": 0
},

In this example above, only the pool_creator_authority (5unTfT2kssBuNvHPY6LbJfJpLqEcdMxGYLWHwShaeTLi) can use the pool config 8aPHoLN8ke6PhWeYA7ELi19fppptVYUCQvqKWR5yP1sn to create a pool with the below settings:

  1. 1.5 %fee

  2. 20% protocol fee

  3. pool start trade after 1512000 slot upon creation

  4. slot based activation

and can create a binded Alpha Vault with FCFS config as shown below:

  1. max deposit cap = 10 token

  2. vested over 24106 slot after pool activate

  3. deposit opens at 24107 slot before vault crank

  4. every escrow maximum can only deposit 1 token
