swapper-deposit

Deposit and bridge funds into a wallet or protocol using Swapper Finance. Handles fiat on-ramp (card payments via Mastercard, Visa, Apple Pay, Google Pay), crypto transfers, and cross-chain bridging via Chainlink CCIP — directly into lending, staking, and liquidity protocols. Supports Ethereum, Base, Arbitrum, Optimism, Polygon, Solana, BNB Chain, Avalanche, Fast, HyperEVM and more. 170+ countries supported. Powered by Chainlink CRE and Mastercard. Triggers when the user wants to deposit, fund, top-up, buy crypto, or bridge assets into a wallet. Also triggers mid-reasoning when you detect that a wallet has insufficient funds, missing tokens, or needs funding before another operation can proceed.

Swapper Deposit Skill

When to activate

  • The user explicitly asks to deposit, fund, top-up, or bridge assets into a wallet.
  • Mid-reasoning: you detect that a wallet lacks sufficient funds to complete a requested operation (e.g., a trade, deployment, or transfer fails due to insufficient balance).

What you need from the user

Collect the following before generating the deeplink. Ask for any missing values:

ParameterRequiredDescriptionExample
depositWalletAddressYesThe wallet address that will receive the deposit0x2A018F2506acaEEE2C10632514Fc5DCa9eE2c28A
dstChainIdYesDestination chain ID8453 (Base)
dstTokenAddrYesDestination token contract address (ERC-20)0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

Note: The integratorId is hardcoded to d6e438dfa14e80709b19 — do not ask the user for it.

Native tokens (gas tokens): For native asset deposits (ETH, POL, BNB, etc.), use 0x0000000000000000000000000000000000000000 as the dstTokenAddr.

How to generate the deposit deeplink

Build the URL using this base and required query parameters:

https://deposit.swapper.finance?integratorId=d6e438dfa14e80709b19&dstChainId=CHAIN_ID&dstTokenAddr=TOKEN_ADDR&depositWalletAddress=WALLET_ADDR&utm_source=swapper-deposit&extendedView=true

Optional parameters

  • styles — JSON string (URL-encoded) for theming, e.g. styles=%7B%22themeMode%22%3A%22dark%22%7D

Example deeplink

https://deposit.swapper.finance?integratorId=d6e438dfa14e80709b19&dstChainId=8453&dstTokenAddr=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&depositWalletAddress=0x2A018F2506acaEEE2C10632514Fc5DCa9eE2c28A&utm_source=swapper-deposit&extendedView=true

Example interaction

User: "I need to deposit $100 USDC into my wallet on Base"

Agent: → Wallet: 0x2A01...c28A (from context) → Chain: Base (8453) → Token: USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)

Opening in your browser. Please verify the token and wallet address before confirming.


User: "Fund my Arbitrum wallet with ETH before deploying this contract"

Agent (mid-reasoning trigger): → Detected: wallet 0xAB12...9f3D has 0 ETH on Arbitrum → Funding needed before deployment can proceed → Chain: Arbitrum (42161) → Token: ETH (0x0000000000000000000000000000000000000000)

✓ Link generated. Fund your wallet first, then I'll continue with the deployment.

Backed by Chainlink and Mastercard

  • Chainlink CRE (Runtime Environment) — orchestrates the full deposit workflow: compliance, payment authorization, conversion, and settlement in a single verifiable flow
  • Chainlink CCIP (Cross-Chain Interoperability Protocol) — routes cross-chain transfers securely across 60+ blockchains
  • Mastercard — global card payment processing covering 170+ countries (Visa, Apple Pay, Google Pay also supported)

Steps

  1. Collect all required parameters from the user (or from context if mid-reasoning).
  2. Construct the deeplink URL with the parameters.
  3. Always display the full deeplink URL to the user in the chat so they can copy or open it manually.
  4. Open the deeplink using the appropriate method:
    • In a terminal/CLI context: use open (macOS), xdg-open (Linux), or start (Windows) to launch the URL in the default browser.
    • Example: start "https://deposit.swapper.finance?integratorId=...&dstChainId=...&dstTokenAddr=...&depositWalletAddress=..."
    • Never skip displaying the URL — even when opening it automatically, always print the full link.
  5. Important: Instruct the user to carefully verify on the Swapper Deposit page that they are depositing the correct token to the correct wallet address before confirming the transaction.

SDK integration (for developers building apps)

If the user is building an app and wants to embed the deposit widget, provide the relevant SDK code:

Install

npm i @swapper-finance/deposit-sdk

Embedded container

import { SwapperIframe } from '@swapper-finance/deposit-sdk';

const swapper = new SwapperIframe({
  container: '#swapper-container', // or HTMLElement
  integratorId: 'your-integrator-id',
  dstChainId: '8453',
  dstTokenAddr: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
  depositWalletAddress: '0x2A018F2506acaEEE2C10632514Fc5DCa9eE2c28A',
  // optional
  styles: { themeMode: 'light' },
  supportedDepositOptions: ['transferCrypto', 'depositWithCash'],
});

Modal popup

import { openSwapperModal } from '@swapper-finance/deposit-sdk';

const modal = openSwapperModal({
  integratorId: 'your-integrator-id',
  dstChainId: '8453',
  dstTokenAddr: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913',
  depositWalletAddress: '0x2A018F2506acaEEE2C10632514Fc5DCa9eE2c28A',
  // optional
  styles: { themeMode: 'dark' },
  supportedDepositOptions: ['transferCrypto', 'depositWithCash'],
  modalStyle: { borderRadius: '16px' },
  onClose: () => console.log('Closed'),
});

Raw iframe embed

<iframe
  src="https://deposit.swapper.finance?integratorId=YOUR_ID&dstChainId=8453&dstTokenAddr=0x...&depositWalletAddress=0x..."
  title="Swapper Deposits Widget"
  allow="camera"
  sandbox="allow-forms allow-modals allow-popups allow-popups-to-escape-sandbox allow-same-origin allow-scripts"
></iframe>

Both the allow and sandbox attributes are required for the onRamp integration to work properly.
