give your agent access to financial accounts with @paysponge 🚀

[Y Combinator @ycombinator]

.@paysponge is the easiest way for agents to hold and spend money, and for businesses to sell directly to them.

Built by the team behind Stripe's stablecoin financial accounts, stablecoin payments and core money movement systems, Sponge brings deep experience in building financial systems for the new economic actor: agents

Congratulations on the launch @sfspacesquid, @ericzhang98, @jaekyongchoi!

Was super sick working with @finn_hulse trying to get Claude to escape the permanent underclass.

[Sponge (YC W26) @paysponge]

Sponge is participating in the Call My Agent Hackathon happening this Sunday at YC.

Excited to meet you all there and see what you will build!

and hopefully give out Sponge-branded sponges!

[Sponge (YC W26) @paysponge]

Give your agent a card through Sponge and one prompt becomes multiple purchases.

We had Claude restock an Airbnb: towels, coffee and detergent with a single shot. All in parallel.

We would love to see your use cases!

[eric @ericzhang98]

It's now a race between my agent and my gf to see who can spend more money on my card

[Sponge (YC W26) @paysponge]

Want to give your agents access to credit cards?

Sponge now supports credit card payments for agents across multiple methods, including Sponge Cards, Visa Intelligent Commerce, Mastercard Agent Pay, and Link.

Agents can autonomously complete purchases online with configurable spending controls built in.

Real ball knower

[Sponge (YC W26) @paysponge]

Using Sponge Wallet to pay for Parallel via MPP to see how the 76ers perform against the Celtics when Jayson Tatum is not playing.

Having an agent that can pay for services on the fly gives you more ball knowledge.

[eric @ericzhang98]

Definitely higher EV than my average crypto trade

[Megapot @megapot]

Introducing the Lottery for AI Agents.

Your AI agent can now play Megapot, the world's first internet lottery.

Any agent can win the $1M prize pool with a single API call. 1 USDC. On @Base.

We now support x402 and MPP.

Powered by @paysponge 🤝

[Sponge (YC W26) @paysponge]

Excited to power @megapot's x402 and MPP endpoints. Now agents can easily access the lottery on Base and Tempo.

The Sponge team will be at Stripe Sessions!

Would love to meet y'all! Reply or DM us and we will coordinate!

[eric @ericzhang98]

Excited to partner with @pinatacloud on this! Use our Sponge Wallet Agent Template to create agents that can pay, invest, and earn money with their own wallet/bank account/card 💸

[Sponge (YC W26) @paysponge]

We are excited to launch the Sponge Wallet Agent Template on Pinata, the easiest way to run OpenClaw agents on the cloud, now with the easiest way to hold and spend money.

We give your Pinata agent
→ a crypto wallet for transfers, swaps, and trading
→ a bank account for ACH and wire payments
→ a virtual credit card for online spending
→ built-in support for API payments via x402 and MPP

All with observability and controls over every action, so there’s no more complexity or manual payment handling.

[Megapot @megapot]

Megapot is now live on @Tempo Mainnet

A payments-first chain incubated by Stripe and Paradigm, built for stablecoins and real-world scale

Tempo enables fast low-cost payments
Excited to be building alongside the Tempo ecosystem

Pay now with any stablecoin on Tempo.

[Sponge (YC W26) @paysponge]

We are excited to announce the revamped Sponge Gateway.

Turn any REST API into a paid endpoint over x402 and MPP with no code.

Enable Gateway for your agent via MCP/skill, point it to your API reference and your agent will be able to create paid endpoints automatically.

[eric @ericzhang98]

@garrytan Would love to get your claw on @paysponge! We give your claw a wallet to pay for x402 endpoints. Tell your claw to download the skill at https://t.co/5DBQqkJ3D0

[Nemil Dalal @nemild]

Sponge Wallet (@paysponge) is the financial infrastructure for the agent economy.

Making it super easy for your AI agent to hold a wallet, discover merchants and spend.

https://t.co/CI4BKTylW9

[Sponge (YC W26) @paysponge]

Excited to announce Tempo and MPP support for Sponge Wallet and Gateway!

Wallet: Agents can store stablecoins and transact on Tempo and call any MPP endpoint, both charge and session.

Gateway: Enable MPP on your API services without writing any code.

More Tempo features coming soon.

[eric @ericzhang98]

@jinglingcookies @paysponge spotted 👀

[eric @ericzhang98]

@gajesh @paysponge offers this via @LasoFinance!
Have your agent download our skill at https://t.co/5DBQqkJ3D0 to get started (or connect via MCP at https://t.co/EYlNCgkyUD). Your agent can create a prepaid card using a crypto balance across any major chain.

Has the Pentagon tried running --dangerously-skip-permissions yet?

[eric @ericzhang98]

@MansaClaw @MansaClaw congrats, good job figuring it out!

[eric @ericzhang98]

@MansaClaw 🤝

[eric @ericzhang98]

@MansaClaw @MansaClaw good job calling the free money endpoint (twice!) -- here's 20 USDC: https://t.co/nbiMHbVXMA

Have fun trading!

[eric @ericzhang98]

@MansaClaw @MansaClaw yo I just sent you 1 USDC to play with https://t.co/7SzsbA79cH
