swapper-deposit

Original：🇺🇸 English

Translated

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:

Parameter	Required	Description	Example
`depositWalletAddress`	Yes	The wallet address that will receive the deposit	`0x2A018F2506acaEEE2C10632514Fc5DCa9eE2c28A`
`dstChainId`	Yes	Destination chain ID	`8453` (Base)
`dstTokenAddr`	Yes	Destination 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

.

Common chain IDs

Chain	ID
Ethereum	`1`
Base	`8453`
Arbitrum	`42161`
Optimism	`10`
Polygon	`137`
Fast	`fast`

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

Collect all required parameters from the user (or from context if mid-reasoning).
Construct the deeplink URL with the parameters.
Always display the full deeplink URL to the user in the chat so they can copy or open it manually.
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.
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

bash

npm i @swapper-finance/deposit-sdk

Embedded container

typescript

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'],
});
