Following its mission to foster the growth of AI Beings, renowned AI platform CARV aims to introduce a new class of agents: AI-powered digital extensions of individuals, anchored in verifiable identity and private context.
As such, CARV has announced the launch of Cashie, a programmable on-chain layer that turns real social engagement into verifiable economic activity. As the ecosystem continues to evolve, Cashie has integrated x402.
The launch seeks to bridge the Social and Economic Ledgers that have long operated in silos. While Cashie is evolving into a core protocol for trustless coordination between influence and value, it will no longer serve as just a social payment tool.
It is important to note that Cashie 2.0 is not just a platform; it is a programmable tool for other AI agents. CARV is exposing an AI-native HTTP API that fully implements the x402 protocol.
This means another AI agent (from Virtual, Base, or anywhere else) can now programmatically hire Cashie to run a campaign. Hence, an agent can call the API, receive a 402 Payment Required challenge, and then resubmit its request with its own X-Payment proof to fund and launch the entire operation autonomously.
Cashie Integrates x402 Protocol
Notably, as part of CARV’s broader modular agentic infrastructure, alongside CARV ID (ERC-7231), Model Context Protocol (MCP), and the Shielded Mind update, Cashie’s integration with x402 protocol transforms social engagement into verifiable, automated, and privacy-preserving on-chain rewards, pushing the boundaries and limits of the creator economy, turning social capital into on-chain value.
According to the announcement, Cashie 2.0 is architected around three foundational pillars: x402 payment as the pledge, CARV ID as the proof, and ERC-8004 agent as the executor.
With x402 Payment- ‘The Pledge’, Cashie campaigns begin with a single ERC-3009 signature, where a project or KOL pledges funds to a campaign.
This is the “X-Payment” proof, and it’s verified on-chain. No gas. No manual transfer. It ensures that funds are committed and can be distributed autonomously.
Furthermore, CARV ID serves as the identity oracle that connects the Social Ledger to the Economic Ledger. Lastly, ERC-8004 Agent-‘The Executor’ allows Cashie to perform its functions trustlessly and autonomously, removing manual ops and Sybil vectors.
Notably, the launch of Cashie 2.0 allows CARV to introduce a new kind of developer stack: one that’s not just programmable, but agent-native.
Nonetheless, it is important to note that the company has built the CARV x402 Facilitator to enable secure, gasless campaigns at scale.
CARV x402 Facilitator is a high-performance verifier that adds state and nonce tracking to instantly reject replayed signatures, preventing duplicate settlements before gas is spent.
Notably, CARV is opening its facilitator endpoints for any developer on Base to build their own x402-powered applications. As such, developers can start building against their live endpoints, spanning from a stateless endpoint to validate an x402 paymentPayload (ERC-3009 signature), to a stateful endpoint that verifies and executes the on-chain settlement.
While token standards fragment the web3 ecosystem, not all ERC-20 tokens support gasless approvals or signature-based authorizations. However, Cashie was designed for inclusivity. CARV built Cashie for the entire Base ecosystem, not just for tokens with ERC-3009 support. The platform includes a separate, robust txhash-based verification API.
Notably, CARV’s internal capability will allow any project to sponsor a campaign with their own (and any) native ERC-20 token, even if it doesn’t support permit or authorization. The sponsor sends a standard on-chain transfer and provides the txHash as proof.
CARV’s system provides secure on-chain verification and replay protection, making Cashie the most flexible and inclusive social-growth engine on Base, with a clear roadmap to open universal token support to all builders.
The launch of Cashie introduces a new way to engage and earn, allowing users to receive crypto rewards directly through social actions like retweets or quests, without wallet submission required, with CARV ID ensuring verified ownership and privacy preserved.
For developers, Cashie becomes a programmable growth layer where automated campaigns, bounties, and agent-driven incentives can be built without manual wallet collection, enabling new composable experiences across social and on-chain environments.
CARV Unveils $45,000 Incentive Program to Boost Adoption
Following efforts to boost adoption of its platform, CARV has launched the Cashie 2.0 Creator Campaign, offering a $45,000 prize pool to incentivize creators and participants.
Through this campaign, the Creators (e.g., KOLs and projects) can configure a reward pool, duration, and eligibility logic and then publish a campaign link via a single social post.
