# Earn referral fees

> Take up to 15 bps on every transfer you send through Bridg. Two fields on the quote.

## Prerequisites

* The [TypeScript project](/guides/typescript-setup).
* One wallet per chain family you refer on. The share is paid on the source chain.

## Script

```typescript src/earn-referral-fees.ts theme={null}
import { createClient } from '@kernlog/bridg-sdk';

const bridg = createClient();
const REFERRAL: Record<'evm' | 'svm', string> = {
  evm: '0xYourEvmWallet',
  svm: 'YourSolanaWallet',
};

async function main() {
  const quote = await bridg.getQuote({
    fromChain: 'base',
    toChain: 'solana',
    fromToken: 'USDC',
    toToken: 'USDC',
    amountAtomic: '100000000',
    sender: '0xUserWallet',
    recipient: 'UserSolanaWallet',
    referralWallet: REFERRAL.evm, // must be valid on the SOURCE chain
    referralBps: 10,
  });

  // Disclosed next to the platform fee, in the input asset, before anything is signed
  console.log(quote.fees.referral); // { bps: 10, amountAtomic: '100000', asset: '0x8335…', wallet: '0xYour…' }

  // Later: each fee leg on the transfer reports where your share is
  const transfer = await bridg.getTransfer('transferId');
  for (const fee of transfer.fees) console.log(fee.kind, fee.status, fee.amountAtomic, fee.txHash);
}

main().catch((e) => { console.error(e); process.exit(1); });
```

## Notes

* Both fields or neither. `referralBps` is `0` to `15`. Your share on one transfer is capped at \$10.
* The share is paid in the same signature as the bridge: an instruction inside the Solana transaction, or the `fee` step beside the EVM call. Nothing is forwarded later.
* Your share is taken even on a transfer Bridg itself charges nothing for. `fees.referral` is `null` only when no referrer was named.
* Fee status moves `offered` → `expected` → `settled`, or `void` on a refund or failure. See [Referrals](/concepts/referrals).
