The SDK supports Token 2022 transfer-hook DBC pools through dedicated config, pool, swap, and fee-claim builders. Use this page for the TypeScript integration surface. For product behavior, see DBC Transfer Hook Pools.

Create transfer-hook config and poolclient.partner.createConfigAndPoolWithTransferHook
Create transfer-hook config and pool with first buyclient.partner.createConfigAndPoolWithFirstBuyWithTransferHook
Create pool from transfer-hook configclient.creator.createPoolWithTransferHook

Swapclient.pool.swap2WithTransferHook
Claim partner trading feeclient.partner.claimPartnerTradingFee2
Claim creator trading feeclient.creator.claimCreatorTradingFee2
In SDK 1.5.8+, claimPartnerTradingFee2 and claimCreatorTradingFee2 are transfer-hook fee claim builders. For standard pools with explicit receivers, use claimPartnerTradingFeeToReceiver and claimCreatorTradingFeeToReceiver.

​
State Reads

SDK 1.5.9 fetches both standard and transfer-hook account variants through the same state methods. 
const configState = await client.state.getPoolConfig(config);
const poolState = await client.state.getPool(pool);

if (!configState || !poolState) {
  throw new Error("DBC account not found");
}

const configAddress = poolState.poolState.config;
const baseMint = poolState.poolState.baseMint;
Raw Anchor account fetchers still use different account names: poolConfig versus configWithTransferHook, and virtualPool versus transferHookPool.

​
Create A Transfer-Hook Config

Transfer-hook configs require TokenType.Token2022 and a valid executable transfer-hook program. 
import {
  buildCurveWithMarketCap,
  DynamicBondingCurveClient,
  SwapMode,
  TokenAuthorityOption,
  TokenDecimal,
  TokenType,
} from "@meteora-ag/dynamic-bonding-curve-sdk";
import { Connection, Keypair, PublicKey } from "@solana/web3.js";
import { NATIVE_MINT } from "@solana/spl-token";

const connection = new Connection(process.env.RPC_URL!, "confirmed");
const client = DynamicBondingCurveClient.create(connection, "confirmed");

const payer = Keypair.generate();
const config = Keypair.generate();

const configParams = buildCurveWithMarketCap({
  token: {
    tokenType: TokenType.Token2022,
    tokenBaseDecimal: TokenDecimal.SIX,
    tokenQuoteDecimal: TokenDecimal.NINE,
    tokenAuthorityOption: TokenAuthorityOption.CreatorUpdateAndMintAuthority,
    totalTokenSupply: 1_000_000_000,
    leftover: 0,
  },
  fee,
  migration,
  liquidityDistribution,
  lockedVesting,
  activationType,
  initialMarketCap,
  migrationMarketCap,
});

const createConfigTx = await client.partner.createConfigWithTransferHook({
  ...configParams,
  config: config.publicKey,
  feeClaimer: payer.publicKey,
  leftoverReceiver: payer.publicKey,
  payer: payer.publicKey,
  quoteMint: NATIVE_MINT,
  transferHookProgram: new PublicKey("TRANSFER_HOOK_PROGRAM"),
});
CreatorUpdateAndMintAuthority and PartnerUpdateAndMintAuthority are only valid for transfer-hook configs. Standard configs reject mint-authority options.

​
Create A Transfer-Hook Pool

const baseMint = Keypair.generate();

const createPoolTx = await client.creator.createPoolWithTransferHook({
  baseMint: baseMint.publicKey,
  config: config.publicKey,
  name: "TEST",
  symbol: "TEST",
  uri: "https://example.com/token.json",
  payer: payer.publicKey,
  poolCreator: payer.publicKey,
  transferHookProgram: new PublicKey("TRANSFER_HOOK_PROGRAM"),
});
The SDK derives the pool and vault accounts inside the transaction builder. If you need the pool address, use deriveDbcPoolAddress(quoteMint, baseMint, config). Transfer-hook first-buy builders also use the transfer-hook swap path. They attempt to resolve the base mint’s hook remaining accounts automatically. If the hook cannot be resolved while bundling pool initialization with the first buy, pass transferHookAccountsInfo and transferHookAccounts on the first-buy params.

​
Swap A Transfer-Hook Pool

swap2WithTransferHook uses the same SwapMode variants as swap2. The SDK resolves transfer-hook extra accounts from the base mint and passes TransferHookAccountsInfo for you. 
const quote = client.pool.swapQuote2({
  virtualPool: poolState,
  config: configState,
  swapBaseForQuote: false,
  hasReferral: false,
  eligibleForFirstSwapWithMinFee: false,
  currentPoint,
  swapMode: SwapMode.ExactIn,
  amountIn,
  slippageBps: 100,
});

const swapTx = await client.pool.swap2WithTransferHook({
  owner,
  payer,
  pool,
  swapBaseForQuote: false,
  referralTokenAccount: null,
  swapMode: SwapMode.ExactIn,
  amountIn,
  minimumAmountOut: quote.minimumAmountOut!,
});
When a referral account is present and the referral fee is paid in base tokens, the SDK includes both AccountsType.TransferHookBase and AccountsType.TransferHookBaseReferral slices.

​
Claim Trading Fees

const partnerClaimTx = await client.partner.claimPartnerTradingFee2({
  feeClaimer,
  payer,
  pool,
  receiver: feeReceiver,
  maxBaseAmount,
  maxQuoteAmount,
});

const creatorClaimTx = await client.creator.claimCreatorTradingFee2({
  creator,
  payer,
  pool,
  receiver: creatorReceiver,
  maxBaseAmount,
  maxQuoteAmount,
});
For standard pools, use the non-transfer-hook claim methods:
Standard Pool ClaimSDK Method
Partner claim with optional receiver and temporary wSOL accountclient.partner.claimPartnerTradingFee
Partner claim to explicit receiverclient.partner.claimPartnerTradingFeeToReceiver
Creator claim with optional receiver and temporary wSOL accountclient.creator.claimCreatorTradingFee
Creator claim to explicit receiverclient.creator.claimCreatorTradingFeeToReceiver

​
Completion

When the transfer-hook pool completes its bonding curve, DBC revokes the base mint’s transfer-hook program id and transfer-hook authority. After completion, use the normal DAMM v2 migration methods: 
const { transaction, firstPositionNftKeypair, secondPositionNftKeypair } =
  await client.migration.migrateToDammV2({
    payer,
    pool,
    dammConfig,
  });
