Sponge Wallet Agent

by Sponge

An agent pre-configured with a Sponge Wallet to perform financial tasks using its own crypto wallet, bank account, and credit card

Sponge Wallet Agent
What is this?

A pre-configured agent template backed by the Sponge Wallet skill. Deploy it and get an agent that has its own crypto wallet, bank account, and credit card, separate from yours.

No CLI. Every operation is a plain REST call to https://api.wallet.paysponge.com. The skill file contains instructions and context on how to call each API endpoint.

What is Sponge?

Sponge gives your agent a securely managed crypto wallet, bank account, and credit card to move money and make payments autonomously, with full observability and controls over every action.

Key Capabilities
  • Securely managed crypto wallets with transfers, bridging, swaps, and trading on Hyperliquid and Polymarket
  • Virtual bank accounts to send and receive ACH and wire transfers
  • Virtual credit cards to make online payments
  • x402 / MPP payments to pay for API services without an API key or account
  • Observability and controls for each action your agent does

The agent loads the canonical skill doc at build time into skills/sponge/SKILL.md and uses it as the authoritative reference for every endpoint, parameter, and flow.

Example prompts

Balances and transfers

"Show my balances across all chains and prepare a 10 USDC transfer on Base"

Swap token / bridge across chains

"Swap 1 SOL into USDC on Solana" or "Bridge 25 USDC from Base to Solana"

Polymarket / Hyperliquid trading

"Search Polymarket for 2028 election markets" or "Place a 0.001 BTC market order on Hyperliquid"

Send ACH / wire transfers with a virtual bank account

"Check my bank account status, get my virtual account details, list linked bank accounts, and prepare a $100 wire transfer. Ask for confirmation before you actually send it."

Make purchases with a Sponge Card

"Create a Sponge Card, get my card details, fund it with $10, and use it to purchase credits on Openrouter."

Find and call a paid API (via x402 or MPP)

"Discover an image generation service and generate a futuristic city at sunset. Tell me the price before calling it."

How it works
  1. Deploy the template on Pinata and open the chat
  2. The agent introduces itself and registers an agent-first Sponge Wallet via POST /api/agents/register — the API key is returned immediately
  3. The agent shares a claim URL — you open it in your browser to link the agent to your Sponge account
  4. Fund your Sponge Wallet at wallet.paysponge.com (or transfer crypto from a crypto wallet you own)
  5. Ask for anything — check balances and transfer tokens, swap or bridge across chains, trade on Polymarket or Hyperliquid, send ACH/wire transfers from a virtual bank account, fund a Sponge Card to make online purchases, or discover and pay for x402/MPP APIs. The agent picks the right endpoint and executes with your confirmation.

By default, transactions over 1 usd require explicit confirmation. Spending limits and controls are configurable.

Post-deploy setup

Open the chat and the agent handles everything from there.
