Dynamic Fee Sharing TS SDK Examples

These examples show the SDK flow shape. They return unsigned transactions that your app should sign, simulate, submit, and confirm through its own wallet or backend signer flow.

Create A Non-PDA Fee Vault

import { Keypair } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";
import { DynamicFeeSharingClient } from "@meteora-ag/dynamic-fee-sharing-sdk";

const client = new DynamicFeeSharingClient(connection, "confirmed");
const feeVault = Keypair.generate();

const tx = await client.createFeeVault({
  feeVault: feeVault.publicKey,
  tokenMint,
  tokenProgram: TOKEN_PROGRAM_ID,
  owner: owner.publicKey,
  payer: payer.publicKey,
  userShare: [
    { address: userA.publicKey, share: 600 },
    { address: userB.publicKey, share: 400 },
  ],
});

// Sign with payer and feeVault.

Use this flow when the vault address can be generated and stored by your integration.

Create A PDA Fee Vault

import {
  deriveFeeVaultPdaAddress,
  DynamicFeeSharingClient,
} from "@meteora-ag/dynamic-fee-sharing-sdk";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";

const client = new DynamicFeeSharingClient(connection, "confirmed");
const feeVault = deriveFeeVaultPdaAddress(base.publicKey, tokenMint);

const tx = await client.createFeeVaultPda({
  base: base.publicKey,
  tokenMint,
  tokenProgram: TOKEN_PROGRAM_ID,
  owner: owner.publicKey,
  payer: payer.publicKey,
  userShare: [
    { address: userA.publicKey, share: 600 },
    { address: userB.publicKey, share: 400 },
  ],
});

// Sign with payer and base.

Use this flow when the vault must be recoverable from (base, tokenMint) or must sign source-program fee claim instructions.

Fund A Fee Vault Directly

import BN from "bn.js";

const tx = await client.fundFeeVault({
  feeVault,
  funder: funder.publicKey,
  fundAmount: new BN("1000000"),
});

// Sign with funder.

The SDK creates the funder’s associated token account if needed. For native SOL, it wraps SOL before funding.

Claim User Fees

const tx = await client.claimUserFee({
  feeVault,
  user: userA.publicKey,
  payer: payer.publicKey,
});

// Sign with payer and userA.

Use claimUserFee2 when the claimant signs but receives into another receiver’s associated token account:

const tx = await client.claimUserFee2({
  feeVault,
  user: userA.publicKey,
  payer: payer.publicKey,
  receiver: receiver.publicKey,
});

// Sign with payer and userA. The receiver does not sign.

Read Vault State

const feeVaultState = await client.getFeeVault(feeVault);

console.log(feeVaultState.totalFundedFee.toString());
console.log(feeVaultState.totalShare);

const breakdown = await client.getFeeBreakdown(feeVault);

for (const userFee of breakdown.userFees) {
  console.log(userFee.address.toBase58(), userFee.feeUnclaimed.toString());
}

Fund From DAMM v2

PDA fee vaults can receive DAMM v2 position fees or rewards through fund_by_claiming_fee. The fee vault must own the DAMM v2 position NFT account before claiming.

const tx = await client.fundByClaimDammV2Fee({
  signer: shareholder.publicKey,
  owner: owner.publicKey,
  feeVault,
  dammV2Pool,
  dammV2Position,
  dammV2PositionNftAccount,
});

// Sign with shareholder. Include any other signers required by your transaction flow.

const tx = await client.fundByClaimDammV2Reward({
  signer: shareholder.publicKey,
  rewardIndex: 0,
  feeVault,
  dammV2Pool,
  dammV2Position,
  dammV2PositionNftAccount,
});

If the position NFT account still belongs to another owner, use setTokenAccountOwnerTx to transfer its token-account authority to the fee vault before using these claim helpers.

Fund From DBC

PDA fee vaults can receive DBC creator fees, partner fees, surplus withdrawals, and migration fees through source-program funding wrappers.

Flow	SDK method	Vault must be configured as
Creator trading fee	`fundByClaimDbcCreatorTradingFee`	`VirtualPool.creator`
Partner trading fee	`fundByClaimDbcPartnerTradingFee`	`PoolConfig.feeClaimer`
Creator surplus	`fundByWithdrawDbcCreatorSurplus`	`VirtualPool.creator`
Partner surplus	`fundByWithdrawDbcPartnerSurplus`	`PoolConfig.feeClaimer`
Migration fee	`fundByWithdrawDbcMigrationFee`	Creator or partner, based on `isPartner`

const tx = await client.fundByClaimDbcCreatorTradingFee({
  signer: shareholder.publicKey,
  creator: creator.publicKey,
  feeVault,
  poolConfig,
  virtualPool,
});

The SDK fetches PoolConfig and VirtualPool state when you do not provide cached state.
