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.

​

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()}`;
}
