Original source: CARV
In CARV's exploration of Sovereign AI Beings, we gradually realized a key fact: the future value comes not only from data and computing power but also from every single real person.
The roadmap for CARV's AI Being depicts a future vision where:
AI is no longer just a tool but becomes a self-sovereign extension of individuals in the digital world—driven by trusted identities and private contexts, capable of replacing users in participating in real economic activities.
To achieve this, AI must connect two previously independent systems:
Social Ledger and Economic Ledger.
Cashie was born in the process of bridging these two worlds.
Cashie was initially designed as a "social-native on-chain payment tool," but its capabilities have far exceeded the original concept. Today, Cashie has evolved into a programmable execution layer, allowing AI agents, creators, and communities not only to participate in the market but also to proactively initiate and drive the construction and growth of the market.
In CARV's more complete modular agent infrastructure—including CARV ID (ERC-7231), Model Context Protocol (MCP), and the new Shielded Mind privacy upgrade—Cashie 2.0 can transform social behaviors into verifiable, automatically executable, and privacy-protected on-chain incentives.
It is no longer just a tool, but a protocol.
Core Pain Point: The Unbridgeable Divide Between Social Ecosystem and On-Chain Ecosystem
Over the past decade, Web3 teams have attempted to convert attention into real actions through airdrops, tasks, incentives, and more. However, most attempts have failed to achieve precision, scalability, and trustworthiness simultaneously:
· Airdrop rewards often go to bots rather than real supporters.
· On-chain operations cannot capture real influence, while true influence remains off-chain.
· Manual distribution lacks automation, complicating processes for developers and leaving them vulnerable to witch attacks.
The two systems have been speaking different languages:
· Social Ledger: Records through likes, retweets, and follows, filled with genuine human signals but trapped within Web2 platforms.
· Economic Ledger: Transparent and programmable blockchain, yet disconnected from real-world contexts.
Cashie is the bridge connecting the two.
Positioning of Cashie in CARV's AI Being Technology Stack
In CARV's AI Being architecture, the capabilities of agents depend on the contexts they can access and the environments in which they can execute tasks. Through the Shielded Mind mainnet upgrade, AI agents have gained private reasoning capabilities; relying on CARV ID (ERC-7231), they possess verifiable identities; and with Cashie, they can finally perform truly meaningful actions based on social behaviors on-chain.
This will unlock new capabilities:
· AI Beings can monitor social sentiment in real-time and programmatically trigger community incentives.
· Users can bind their Twitter/X accounts to CARV ID to receive automatically distributed on-chain rewards.
· Project teams can build communities based on verifiable activities rather than relying on guesswork or rough predictions.
Cashie allows AI to evolve from "passive responders" to "economic participants."
This marks a key step for CARV in building the roadmap for Sovereign AI Beings, especially significant during the Genesis Evolution phase.
How Cashie 2.0 Works: Three Core Pillars
The architecture of Cashie 2.0 consists of three core pillars:
1. x402 Payment—Pledge Mechanism
Every Cashie activity begins with a ERC-3009 signature, where the project team or KOL makes a financial commitment to the activity. This signature serves as "X-Payment" proof and will be verified on-chain. No gas fees, no manual transfers; it ensures that funds are locked and can subsequently enable a fully automated distribution process.
2. CARV ID—The Proof
How to issue rewards for a retweet or other social interactions? Traditional wallets cannot recognize @ usernames on social media, making it difficult to correlate on-chain incentives with off-chain behaviors.
Cashie solves this problem with CARV ID: it can map social behaviors (e.g., a retweet from @user) to on-chain identities (e.g., 0xABC). CARV ID is the identity oracle that connects the Social Ledger and the Economic Ledger.
3. ERC-8004 Agent—The Executor
Cashie is not a single-function bot but an AI execution agent composed of various modular tools, including:
· Payment Tool: Used to verify financial commitments and automatically execute fund transfers.
· Twitter Tool: Used to monitor and analyze interaction behaviors on Twitter/X in real-time.
· Raffle / Quest Tool: Used to automatically draw winners or check if users have completed tasks.
· Distribution Tool: Used to automatically distribute on-chain rewards to eligible users.
All processes are completed under a trustless, fully automated mechanism, requiring no manual intervention and effectively avoiding abuses such as witch attacks.
Developer Breakthrough: Promoting the Rise of Agents-to-Agents Autonomous Economy
To truly unleash the potential of Sovereign AI Beings and promote decentralized collaboration, the underlying infrastructure must evolve quietly yet thoroughly. While external attention is more focused on AI agents and social activities, the real engine driving everything is the innovation deep within the infrastructure.
With the release of Cashie 2.0, CARV introduces a new developer stack:
An infrastructure that is not only programmable but also agent-native for AI agents.
1. CARV x402 Facilitator: Protocol Enhancement Layer
In Cashie, every operation begins with a cryptographic pledge. However, the trustworthiness of the pledge depends on the system that verifies it. Therefore, we have built the CARV x402 Facilitator—a self-hosted, high-performance facilitator service designed for social activity scenarios.
We have solved a key challenge in the standard x402 (ERC-3009) process: state management of payment proofs.
Through our verify endpoint, we have introduced a more robust state and nonce management layer that can instantly reject replayed signatures, intercepting attempts at duplicate settlements at high speed before transaction gas is consumed, providing high-throughput security protection.
We have opened the facilitator's interface, allowing any developer on Base to build their own x402-driven applications. Developers can connect to our online endpoints today:
Stateless Endpoint: Used to verify x402 paymentPayload (ERC-3009 signature)
· https://interface.carv.io/cashie/protocol/verify
Stateful Endpoint: Used to verify and execute on-chain settlements.
· https://interface.carv.io/cashie/protocol/settle
2. AI Native API: Achieving "Agent Hiring Agent" through x402
Staying true to the vision of ERC-8004 (Trustless Agents), Cashie 2.0 is not just a platform; it is a programmable tool for other AI agents to call upon.
We have opened an AI native (agent-native) HTTP API that fully implements the x402 protocol. This means any other AI agent (from Virtual, Base, or any other ecosystem) can programmatically "hire Cashie" to execute an activity.
The process is as follows:
1. An AI agent initiates a request to our API.
2. Receives a 402 Payment Required challenge.
3. It then resubmits the request carrying its own X-Payment proof.
4. This enables automated financial commitment and activity initiation.
The entire process is autonomously completed by the agent, forming a true agent-to-agent social business model.
3. General ERC-20 Support Based on TxHash Verification
The Web3 world is fragmented by different token standards, and not every ERC-20 supports gasless approval or signature-based authorization. However, Cashie's design philosophy is universality and compatibility. We built Cashie for the entire Base ecosystem, not just for tokens that support ERC-3009.
Cashie includes a standalone txHash verification API, allowing any project to initiate incentive activities using any ERC-20 token: the project team only needs to complete a regular on-chain transfer and submit the txHash of that transaction as proof of funds. The system will automatically complete on-chain verification, fund confirmation, and replay protection.
This makes Cashie the most flexible and compatible social growth engine on Base, and it will gradually open up general token support capabilities to all developers.
What Does This Mean for Users and Developers?
For Users (KOLs, community members, and even ordinary individuals):
· No-threshold incentives: As long as you interact on X (such as retweeting or completing tasks), you can receive crypto rewards without manually submitting your wallet address.
· Identity sovereignty: CARV ID ensures your rewards are tied to a verified identity rather than an empty wallet.
· Native privacy protection: Thanks to the Shielded Mind operating environment, your actions and intentions will be protected.
For Developers:
· Programmable social growth: You can build your own agents or use the Cashie API to initiate automated activities, raffles, tasks, etc.
· No need to collect wallet addresses: With ERC-7231 and CARV ID, user identities can be verified on-chain without manually collecting or managing wallets.
· Composable infrastructure: Build content permissions, bounty boards, or AI agent-driven incentive layers based on Cashie.
Cashie 2.0 Campaign
To bring this model to users, CARV officially launches the Cashie 2.0 Campaign, establishing a $45,000 reward pool to encourage creators and users to participate in a new experience of on-chain social incentives. Creators (such as KOLs and project teams) can set their own reward pools, activity durations, and participation logic, and publish activity links through a single social media post. Funds are authorized through gasless x402 signatures and automatically escrowed, while the agent operating environment listens in real-time for social behaviors, determines eligibility, identifies winners, and completes on-chain settlements directly.
Participants only need to complete one identity verification with their social account, without disclosing wallet information. The system will automatically recognize eligibility and distribute rewards to their associated Base wallet, achieving a truly frictionless participation experience without manual wallet collection, spreadsheet management, or gas payments.
How Cashie 2.0 Campaign Works
For Creators (KOLs / Project Teams)
1. Connect Wallet
Go to the activity page: https://carv.io/cashie, log in with your wallet, and bind your X account.
2. Create Activity (Giveaway)
· Set reward amount, number of winners, and activity duration.
· Complete pool authorization through gasless x402 signatures.
· Automatically generate a tweet template that can be published directly.
3. Publish Tweet
One-click to publish the template, and you can start accumulating interaction data.
4. Let the System Run Automatically
Cashie will automatically verify retweets, follows, and all participation conditions; the more participants attracted by the activity, the higher the creator's ranking, and the more incentives they can earn.
5. Automatic Raffle and Reward Distribution
After the activity ends, the AI agent will automatically conduct a fair draw and directly distribute rewards to the winners' Base wallets—no scripts, no spreadsheets, no manual operations required.
Creator Incentives (Creating Raffle Activities)
The more participants the activity attracts, the higher your ranking, and the more rewards you can earn.
How Participants Join
· Participate directly through X (Twitter).
· Log in with Twitter and link your wallet address.
· No gas payments required throughout the process.
· If selected, rewards will be automatically distributed to the Base wallet linked to your X account.
Participant Incentives (Joining Raffles)
The more activities you participate in, the larger your share of the incentive pool.
Next Steps
Cashie has empowered numerous activities for creators and project teams within the Base ecosystem, but this is just the beginning. Next, Cashie will undergo a series of capability upgrades:
· Self-hosted Facilitators: Developers can independently deploy x402 services to build flexible social payment logic on Base.
· AI Activity Agents: Based on real-time trends and sentiment changes, AI agents will be able to autonomously initiate activities, achieving truly data-driven automated growth.
· Enterprise-level Integration: Launching on-chain social growth SDKs for marketing and growth teams, providing deep integration solutions for channels like Telegram and Discord.
· Cashie SDK: Helping developers build their own incentive activity layers at a faster pace.
These capabilities will drive Cashie to become the core entry point for CARV Agentic AI and the Base SocialFi ecosystem, moving beyond simple token incentives to allocate resources to truly valuable, verifiable participatory behaviors.
The birth of Cashie 2.0 signifies a true paradigm shift: it connects social attention with on-chain incentives for the first time, bringing social capital into a programmable, verifiable new era. Cashie is not just a tool but the infrastructure of a programmable social economy:
· AI agents execute tasks with clear intent,
· Users receive fair rewards for genuine interactions,
· Developers can build new collaboration and growth models.
As the CARV AI Being roadmap moves to the next stage, Cashie will become the key engine connecting "people ↔ machines" and "influence ↔ value," opening up new spaces for trustless collaboration.
The social ledger is finally truly on-chain.
