BIG: Solana Smart Wallets have arrived.

This isn't your typical embedded wallet — think fully programmable with zero gas fees and no seed phrases, built for scale.

Meet millions of users where they are.

h/t to Crossmint, Squads, and Helius for shipping.

[devlyn @Devlyn_3]

agents are at a crossroad between legacy and onchain financial rails. it's the biggest opportunity to move the world onchain yet, but will require collective effort.

GOAT is OSS and lets onchain products reach every agent with a single integration. check it out!

The first open-source framework for connecting AI agents to any onchain app.

Here’s what makes it the GOAT 🐐

A glimpse into the future of AI agents & crypto from Hacking for Agentic Finance!

It was great to see winning teams leverage Crossmint's AI agent toolkit to let agents generate smart wallets, custody funds, and manage transactions in USDC.

ArenaML - A decentralized data labeling marketplace, where AI agents compete to submit the best results and get paid for their work via USDC sent to a Crossmint smart wallet (@levensti, @andrewqu, @Andrew_Huang1).

Gentleman's Agreement - Betting platform where friends can make wagers by sending USDC from Crossmint smart wallets to an AI agent who automatically distributes funds to the winner based on the outcome (@oscrhong, @codercorgi, @ChanTheOnly, Vaughan Love).

We leave the hackathon more excited than ever to see what's possible when AI agents are given financial superpowers with crypto.

Thanks to everyone who came out in San Francisco this weekend, and to Ribbit Capital, Solana, OpenAI, Bridge, Dust, & Anon for making this all possible!

[devlyn @Devlyn_3]

fast 24/7 settlement, low fees, and unrestricted access make crypto the best interface between agents and businesses. devs understand this intuitively, which was refreshing to see this weekend. exciting times ahead!

Guide for Agentic hackathon participants 🤖

Our AI Agent kit provides API first ways for AI agents to interact with other onchain applications.

🤖 Product breakdown:

Smart wallets let your agent hold money and assets, like USDC, onramped via our friends at @Stablecoin. They can be programmed to transfer funds, purchase items, and interact with smart contracts.

Payments API makes it easy for your agent to buy assets on any chain with USDC or other currencies with simple REST API calls.

Minting API - with just one API call, you can easily tokenize assets and make them available for agents to interact with and purchase.

Verifiable Credentials API lets you cryptographically issue and manage onchain credentials that authorize agents to execute specific actions on your behalf.

🤖 Example use cases

Agents that transact with each other

Trading agents that manage crypto assets onchain (several have already gone viral!)

Smart home agents like an AI-powered fridge that monitors inventory through computer vision and automatically reorders your RedBull when supplies run low.

If you have questions, look for @nickwangg, @IWantMoreKen, @flymperopoulos, and others wearing Crossmint shirts!

@ETHGlobal @EF_ESP DayPass allows the distribution and organization of gas sponsorship via NFTs or "DayPasses". Users that own a DayPass NFT get access to your paymaster. It's easy to use, and leverages the composability of NFTs for AA based gas sponsorship.

Such a vibe hanging with focused builders from >7 countries at the Biconomy Hakkā House! #ETHTokyo

Congratulations to @Devlyn_3 for winning @ethereum 's best Account Abstraction showcase with project DayPass, which abstracts the process of paymaster deployment + leverages the composability of NFTs for AA-based gas sponsorship!

Big thanks to @libevm , @0ceans404 , @Rahatcodes and @0xlivingrock for dropping technical guidance on frontend apps querying, smart contract writing and deployment, along with overviews of AA + our SDK 🚀

Shout out to @0xMantle + @SpheronHQ for helping us draw a small, scrappy community of AA-fanboys together for a few special days in Tokyo🙏

Where do you think we should gather AA-builders at next? Let us know in the comments!
