Withdrawing Affiliate Fees

Affiliate fees can be specified by any integration using the DLN API or the deBridge Widget. The fees are free to be distributed to the designated beneficiary once liquidity is unlocked by a solver from a fulfilled order—typically within a few hours after the order execution.

EVM chains

On EVM chains, affiliate fees are automatically transferred to the specified beneficiary address as part of the transaction in which the solver unlocks liquidity. No additional action is required.

Solana

On Solana, affiliate fees must be claimed manually by the beneficiary. This is done by invoking the withdrawAffiliateFee method of the DLN program. A complete working example for claiming affiliate fees in bulk is available here.

Simplified example snippet:

import { Solana } from "@debridge-finance/dln-client"
import { Connection, PublicKey, clusterApiUrl } from "@solana/web3.js";

function findAssociatedTokenAddress(wallet: PublicKey, tokenMint: PublicKey)
    : [PublicKey, number] {
    return PublicKey.findProgramAddressSync(
        [wallet.toBytes(), 
        new PublicKey("TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA").toBytes(), 
        tokenMint.toBytes()], 
        new PublicKey("ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL")
    );
}

const solanaClient = new Solana.DlnClient(
    // Replace with dedicated RPC for production
    new Connection(clusterApiUrl("mainnet-beta")), 
    new PublicKey("src5qyZHqTqecJV4aY6Cb6zDZLMDzrDKKezs22MPHr4"), 
    new PublicKey("dst5MGcFPoBeREFAA5E3tU5ij8m5uVYwkzkSAbsLbNo"), 
    new PublicKey("DEbrdGj3HsRsAzx6uH4MKyREKxVAfBydijLUF3ygsFfh"), 
    new PublicKey("DeSetTwWhjZq6Pz9Kfdo1KoS5NqtsM6G8ERbX4SSCSft"),
)

type Order = {
    orderId: string;
    beneficiary: PublicKey;
    giveToken: PublicKey;
}

// Load the order using known data or fetch via transaction hash
// const order = await solanaClient.getOrderFromTransaction(
//     { giveChain: ChainId.Solana, txHash: "CREATE_TX_HASH" }
// );
const order: Order = { /* order data */ };

// Build and send the withdraw transaction
const [associatedTokenAddress] = findAssociatedTokenAddress(
    order.beneficiary, 
    order.giveToken
);
const tx = await solanaClient.source.withdrawAffiliateFee(
    order.orderId, 
    order.beneficiary, 
    associatedTokenAddress
);
// Send the transaction...
