Affiliate fee

Affiliate fee can be specified by anyone who integrates with DLN API or uses a deSwap widget. The fee is received by the beneficiary at the moment when the market maker unlocks liquidity from the fulfilled trade (usually a few hours after the trade is fulfilled).

Withdrawal

EVM chains

For cross-chain transfers initiated from EVM chains, the affiliate fee is transferred to the beneficiary address automatically in the same transaction where the market maker unlocks liquidity from the fulfilled trade.

Solana

For trades initiated from Solana, the affiliate fee is not transferred automatically and should be claimed by the beneficiary by interacting with the DLN program on Solana. withdrawAffiliateFee the method should be called. Here is how it can be done using DLN Client:

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(
    new Connection(clusterApiUrl("mainnet-beta")), // better use your own RPC
    new PublicKey("src5qyZHqTqecJV4aY6Cb6zDZLMDzrDKKezs22MPHr4"), 
    new PublicKey("dst5MGcFPoBeREFAA5E3tU5ij8m5uVYwkzkSAbsLbNo"), 
    new PublicKey("DEbrdGj3HsRsAzx6uH4MKyREKxVAfBydijLUF3ygsFfh"), 
    new PublicKey("DeSetTwWhjZq6Pz9Kfdo1KoS5NqtsM6G8ERbX4SSCSft"),
)
type Order = {
    orderId: string;
    beneficiary: PublicKey;
    giveToken: PublicKey;
}
// load order in expected format
const order: Order; 
// order could also be loaded from chain by order creation tx hash
// const order = solanaClient.getOrderFromTransaction({ giveChain: ChainId.Solana, txHash: "create tx hash" }, {});

// build withdraw tx
const tx = await solanaClient.source.withdrawAffiliateFee(order.orderId, order.beneficiary, findAssociatedTokenAddress(order.beneficiary, order.giveToken)[0]);
// send withdraw tx
