CARV Launches Cashie 2.0: Turning Social Engagement Into On-Chain Value

At its core, Cashie 2.0 is architected as a bridge between two historically separate systems: the Social Ledger of online engagement and the Economic Ledger of blockchain value. This connection is engineered through three foundational pillars. The first, ‘x402 Payment’ or ‘The Pledge,’ allows a project or Key Opinion Leader (KOL) to initiate a campaign with a single ERC-3009 signature, committing funds without gas fees or manual transfers. This creates an on-chain proof that funds are available for autonomous distribution.

The second pillar, ‘CARV ID: The Proof,’ solves a critical identity problem. Traditional crypto wallets cannot verify social media actions like a retweet from a specific @handle. CARV ID, built on the ERC-7231 standard, acts as an identity oracle, mapping verifiable social actions to on-chain identities (e.g., 0xABC). This creates the essential link that proves who performed a social task, enabling trustless reward allocation.

The final component is the ‘ERC-8004 Agent: The Executor.’ Cashie is not a simple bot but an AI-powered agent composed of modular tools. These include a Payment Tool to move funds, a Twitter Tool to monitor social activity, and Raffle or Distribution Tools. Operating autonomously, this agent executes the entire campaign—from verifying actions to distributing rewards—eliminating manual operations and reducing Sybil attack vectors. Together, these three pillars enable a system where a retweet can automatically trigger a verifiable, on-chain crypto payment.

While user-facing features capture attention, CARV’s significant innovation lies in the developer infrastructure powering Cashie 2.0. The company has built a full, agent-native stack to empower builders on the Base blockchain. A key component is the CARV x402 Facilitator, a high-performance verifier that adds state and nonce tracking to ERC-3009 signatures. This prevents duplicate settlements and replay attacks before any gas is spent, enabling secure, gasless campaigns at scale.

CARV is opening this infrastructure to all developers on Base. They provide two critical public endpoints: a stateless endpoint to validate an x402 paymentPayload and a stateful endpoint to verify and execute the on-chain settlement. This allows any developer to build their own x402-powered applications using CARV’s verified infrastructure. Furthermore, in a move aligning with the ERC-8004 vision for trustless agents, CARV exposes an AI-native HTTP API. This enables other AI agents—from platforms like Virtual or elsewhere—to programmatically ‘hire’ Cashie. An agent can call the API, receive a ‘402 Payment Required’ challenge, and resubmit with its own X-Payment proof to autonomously fund and launch a campaign, pioneering true agent-to-agent social commerce.

Recognizing the fragmented nature of Web3 token standards, CARV engineered Cashie for maximum inclusivity. Not all ERC-20 tokens support gasless approvals via standards like ERC-3009. To serve the entire Base ecosystem, Cashie incorporates a robust transaction hash (txHash) verification API. This allows a project to sponsor a campaign with any native ERC-20 token by simply executing a standard on-chain transfer and providing the txHash as proof. CARV’s system handles the secure verification, making Cashie a flexible social-growth engine for virtually any token on the network.

For users, Cashie 2.0 introduces a seamless way to monetize social capital. Individuals can earn crypto rewards for actions like retweets or completing quests without the friction of submitting wallet addresses manually. Their privacy is preserved, and ownership is verified through their CARV ID. This lowers the barrier to entry for participating in the crypto-based creator economy, turning everyday social engagement into a potential revenue stream.

For developers and projects, Cashie becomes a programmable growth layer. It enables the creation of automated campaigns, bounties, and agent-driven incentives without the operational overhead of manual wallet collection and reward distribution. This composability allows for new experiences that blend social environments and on-chain interactions seamlessly. To catalyze adoption of this new model, CARV is launching a Cashie 2.0 Creator Campaign with a $45,000 prize pool. This initiative incentivizes both creators (KOLs and projects) to configure and publish campaigns and participants to engage, demonstrating the protocol’s utility in real-world scenarios on the Base blockchain.
