Create: Stake2Earn Pool with Alpha Vault

Summary

are Dynamic AMM Memecoin Pools that are launched with a Stake2Earn Vault. In this page, we provide the code examples that can be used to initialize and seed a Stake2Earn Pool together with an Alpha Vault.

Memecoin Pool: A Dynamic AMM Pool created with a fee scheduler and with initial liquidity perma-locked.
Stake2Earn Vault: Stake-to-earn farming mechanism and vault where top stakers can earn a share of fees from the locked liquidity.
Stake2Earn Pool: A Memecoin Pool with a Stake2Earn Vault.
Alpha Vault: Anti-sniper tool that allows depositors into the Alpha Vault to be the first to buy from the pool and be guaranteed a share of tokens at the same average price as all other depositors.

1. Install dependencies and initialize AmmImpl instance

1.1 Install dependencies

# NPM
npm i @meteora-ag/dynamic-amm-sdk @coral-xyz/anchor @solana/web3.js @solana/spl-token
# YARN
yarn add @meteora-ag/dynamic-amm-sdk @coral-xyz/anchor @solana/web3.js @solana/spl-token
# Or, use any package manager of your choice.

1.2 Initialize AmmImpl instance

import AmmImpl, { MAINNET_POOL } from '@meteora-ag/dynamic-amm-sdk';
import { Connection, Keypair, PublicKey } from '@solana/web3.js';
import { AnchorProvider, Wallet } from '@coral-xyz/anchor';

// Connection, Wallet, and AnchorProvider to interact with the network
const mainnetConnection = new Connection('https://api.mainnet-beta.solana.com');
const mockWallet = new Wallet(new Keypair());
const provider = new AnchorProvider(mainnetConnection, mockWallet, {
  commitment: 'confirmed',
});
// Alternatively, to use Solana Wallet Adapter

// Create single instance
const constantProductPool = await AmmImpl.create(mainnetConnection, MAINNET_POOL.USDC_SOL);
const stablePool = await AmmImpl.create(mainnetConnection, MAINNET_POOL.USDT_USDC);
// Or with any other pool address, refer to the pool creation section below
const pool = await AmmImpl.create(mainnetConnection, new PublicKey('...'));

// If you need to create multiple, can consider using `createMultiple`
const pools = [MAINNET_POOL.USDC_SOL, MAINNET_POOL.USDT_USDC];
const [constantProductPool, stablePool] = await AmmImpl.createMultiple(mainnetConnection, pools);

2. Choose a suitable Pool and Fee Config

Before creating the pool, you need to choose a suitable pool and fee config.

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.

If none of the pool_config_key in the list meet your requirements, please reach out to Meteora for a custom pool config key.

2.1 Public Pool Config List

- Using this endpoint, integrators can input the config pubkey, and it will return an array of fee update timings for the config, if there's any.
- Integrators may choose a pool_config_key with a fee curve that suits your integration.
If there is no existing config in the list that fits your project's requirement, a new config needs to be created.
Only the Meteora team can create a new config to add it to the preset pool config list.

2.2 Default Pool Config used by Meteora Frontend

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...

2.3 New Custom Pool Config and Fee Curve for Integrators / Launchpads

Custom Pool Config Key: Integrators such as launchpads or other partners may need to use their own unique custom pool config key, if they want custom pool_creator_authority to prevent front-running of the token launch pool.

NOTE:

New dedicated config keys can only be created by Meteora. Please reach out to us if this is required.
The pool_creator_authority doesn't work with program address. It's not a program whitelist, it needs to be a PDA (program derived address) or normal account.

Custom Fee Curve: If you are an integrator, Meteora can also apply a custom fee curve/schedule for your pools, but we will need to create a dedicated config key for your team, where pool_creator_authority is linked to your signer wallet for pool creation. You would need to send us your signer wallet that would be used to deploy the pools.

NOTE:

Even with a dedicated config key for your team, Meteora would need to customize the fee curve/schedule for you. You can't do it on your own.
Custom Pool Config and Fee Curve is used by integrators such as Moonshot by DEX Screener.

2.4 Custom Fee Curve for a Specific Pool

If required, Meteora can set a custom fee curve for a single, specific pool. This would override the fee curve used by the pool's config key, doesn't matter which config key is used.

3. Create the Memecoin Pool

Using the example, update it with your pool config selected and other parameters in order to create a Memecoin Pool - which is a Dynamic AMM Pool with a fee scheduler and with liquidity (LP tokens) locked at creation.

How to assign which wallets can claim fees from the permanently-locked liquidity

Please refer to this example, in the section under let allocations = [

Find your Stake2Earn Vault public key address. Put it in the example above and allocate the % of fees from permanently locked liquidity that you intend to go to the Stake2Earn vault (for top stakers to earn).

How to find the address of the Stake2Earn Vault (before you create it)

4. Create the Stake2Earn Vault

After creating the Memecoin Pool and setting up the fee allocation between wallets, please use this example to create the Stake2Earn Vault:

5. Create the Alpha Vault

Please use this example to create the Alpha Vault:

Alpha Vault with Whitelist

For some launches, the project may want to restrict which wallet addresses are allowed to deposit funds into the Alpha Vault, so in the config file used in the script to create the Alpha Vault, the whitelistMode needs to be specified.

permissionless: No whitelist, anyone can deposit into the Alpha Vault
permission_with_authority: Only wallets that are whitelisted can deposit into the Alpha Vault

Important Notes

You are recommended to configure your Stake2Earn staking rewards distribution start time (fee claim start time) to be approximately 48 hours after launch. This allows more time for total fee rewards to accumulate from trading activity in the memecoin pool. A bigger total fee reward would help make your Stake2Earn Vault look more appealing to potential stakers.
If you do not want to use Alpha Vault, you can just Create a Memecoin Pool with a Stake2Earn Vault.
Currently, only SOL or USDC is accepted as the quote token when initializing a Memecoin Pool, Dynamic AMM Pool, or DLMM Pool with Alpha Vault in a permissionless setup. Since the Alpha Vault can't tell what the quote token would be, the quote token is limited to SOL or USDC. However, any quote token can be used if you use a config key that doesn't have Alpha Vault.
If you plan to use a multisig on the Meteora website, please make sure it is the SquadsX multisig, as that is the only type supported on Meteora website. Otherwise, you can't manage liquidity through the website.
There is a minimum ~1 hour 5 minutes period between the deposit close time and the pool activation time.

Other Configuration Details

There are various config files that can be found in the config directory.

It contains all the configurations required to run the scripts. We also need to provide the keypair for the payer wallet in keypair.json file.

General configuration

rpcUrl: Solana RPC URL to get data and send transactions.
keypairFilePath: Keypair file path to send transactions.
dryRun: Set to true to send transactions.
computeUnitPriceMicroLamports: CU price in micro lamports unit. For example: 100000.
createBaseToken: Configuration to create base token.
baseMint: Base token address if the createBaseToken field is not set.
quoteSymbol: Quote token symbol, only SOL or USDC is supported.
quoteMint: Quote token mint, in case the user wants to create a DLMM launch pool with a token other than SOL or USDC.
dynamicAmm: Dynamic AMM pool configuration.
alphaVault: Fcfs or Prorata Alpha Vault configuration.

Some configuration constraints:

createBaseToken and baseMint cannot be used together.
dynamicAmm and dlmm cannot be used together.

Create Base Token configuration

mintBaseTokenAmount: Base token amount to be minted.

Dynamic AMM configuration

baseAmount: Base token amount.
quoteAmount: Quote token amount.
tradeFeeNumerator: Trade fee numerator, with fee denominator is set to 100_000.
activationType: To activate pool trading base on slot or timestamp.
activationPoint: To activate pool trading at a point, either slot valut or timestamp value base on activationType.
hasAlphaVault: Whether alpha vault is enabled or not for this pool.

Alpha Vault configuration

poolType: dynamic or dlmm pool type.
alphaVaultType: Alpha Vault type, could be fcfs or prorata
depositingPoint: Absolute value that, the slot or timestamp that allows deposit depend on the pool activation type.
startVestingPoint: Absolute value, the slot or timestamp that start vesting depend on the pool activation type.
endVestingPoint: Absolute value, the slot or timestamp that end vesting depend on the pool activation type.
maxDepositCap: Maximum deposit cap.
individualDepositingCap: Individual deposit cap.
escrowFee: Fee to create stake escrow account. If this fee is added, it will be a one-time fee charged when users create a stake escrow account. This acts as a tax and makes it prohibitively expensive for users to attempt to use multiple wallets to bypass the individual deposit cap. It's charged in native SOL (non-wrapped version) and will be sent to the Meteora treasury.
whitelistMode: permissionless or permission_with_merkle_proof or permission_with_authority.

Alpha Vault Prorata configuration

endVestingPoint: Absolute value, the slot or timestamp that end vesting depend on the pool activation type.
maxBuyingCap: Maximum buying cap.
escrowFee: Fee to create stake escrow account. If this fee is added, it will be a one-time fee charged when users create a stake escrow account. This acts as a tax and makes it prohibitively expensive for users to attempt to use multiple wallets to bypass the individual deposit cap. It's charged in native SOL (non-wrapped version) and will be sent to the Meteora treasury.
whitelistMode: permissionless or permission_with_merkle_proof or permission_with_authority.

Alpha Vault Key Components

Vault Types: Supports both permissionless (without whitelist) and permissioned (with whitelist) Alpha Vaults.
