# Sponge

Agent wallet balances, portfolio, and USDC funding links

Listed in ChatGPT

Overview

## What Sponge does

Sponge deals with wallets belonging to an AI agent rather than to a person. Balances can be read out, and the portfolio behind them viewed, from the conversation.

Funding is handled with links. The app creates an onramp link for adding USDC to the wallet, which keeps the payment step outside the chat itself.

Sample prompts cover the three things the listing describes: a portfolio summary, a balance check, and a request to add a fixed dollar amount. Nothing further about how the wallet operates is set out in the record.

### Who it is for

A developer or operator running an agent that holds and spends its own crypto balance.

### What stands out

The wallet in question belongs to an agent, a narrower framing than general crypto portfolio apps use.

## Where Sponge is listed

Sponge is listed in the ChatGPT apps directory only. Sponge Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
