Deposit

Let users deposit tokens to a wallet address from any supported chain

What it does

A hosted deposit page where users can send tokens to a specific wallet address. They connect their wallet, pick a token, and AnySpend handles the cross-chain routing. You generate a URL, they click it.

How it works

1. Your app generates a deposit URL with the recipient address, chain, and token.
2. User connects their wallet (MetaMask, Coinbase, Rainbow, Rabby, Trust Wallet).
3. User picks a token from their available balances.
4. AnySpend routes the payment cross-chain if needed, converting to the destination token.
5. Done — optionally redirect the user back to your app.

URL parameters

The deposit page accepts these URL parameters:

Parameter	Required	Description
recipientAddress	Yes	The wallet address to receive the deposit (valid EVM address)
toChainId	Yes*	The destination chain ID (e.g., 8453 for Base)
toCurrency	Yes*	The token contract address on the destination chain
amount	No	Fixed amount in wei/smallest unit. When provided, user cannot change the amount
redirect_url	No	HTTPS URL to redirect after completion
redirect_label	No	Custom label for the redirect button
partner	No	Partner ID for custom configuration

* Not required for Hyperliquid chain where USDC is the default token.

Example URLs

Basic deposit to Base USDC:

https://anyspend.b3.fun/deposit?recipientAddress=0x1234...&toChainId=8453&toCurrency=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

Fixed amount deposit:

https://anyspend.b3.fun/deposit?recipientAddress=0x1234...&toChainId=8453&toCurrency=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&amount=1000000

With redirect:

https://anyspend.b3.fun/deposit?recipientAddress=0x1234...&toChainId=8453&toCurrency=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913&redirect_url=https://yourapp.com/success&redirect_label=Return+to+App

Supported wallets

Supported out of the box:

• MetaMask
• Coinbase Wallet
• Rainbow
• Rabby
• Trust Wallet

Auto-connect is enabled for returning users who have previously connected their wallet.

Special chain support

Hyperliquid

Hyperliquid gets special handling:

• USDC uses a special 34-character address format (0x00000000000000000000000000000000)
• When toChainId is set to Hyperliquid, toCurrency defaults to USDC if not specified
• Zero addresses are automatically corrected to the Hyperliquid USDC format

Partner integration

Partners can be configured with custom settings:

interface PartnerConfig {
  returnToHomeUrl?: string;      // Default redirect URL
  customRecipientLabel?: string; // Custom label for the recipient
  returnHomeLabel?: string;      // Custom label for return button
}

To register as a partner, contact the AnySpend team to add your configuration.

Security

• Only HTTPS redirect URLs are allowed (prevents open redirect attacks)
• Amounts must be valid positive integers (wei)
• Addresses are validated before processing

Common use cases

• Telegram bots — fund bot wallets via a shareable link
• Gaming — deposit tokens to game accounts
• Marketplaces — fund escrow addresses
• Tipping — let users tip creators with a deposit link

Integration example

Generate a deposit link in your app:

function generateDepositLink({
  recipientAddress,
  chainId,
  tokenAddress,
  amount,
  redirectUrl,
}: {
  recipientAddress: string;
  chainId: number;
  tokenAddress: string;
  amount?: string;
  redirectUrl?: string;
}) {
  const params = new URLSearchParams({
    recipientAddress,
    toChainId: chainId.toString(),
    toCurrency: tokenAddress,
  });

  if (amount) params.set("amount", amount);
  if (redirectUrl) params.set("redirect_url", redirectUrl);

  return `https://anyspend.b3.fun/deposit?${params.toString()}`;
}
