Aven: Streaming Payments & Verifiable Work on Stellar

Aven streams USDC and XLM payments in real time while generating cryptographic proof of work and building portable on-chain reputation on Stellar.

Aven is a decentralized protocol on Stellar that connects clients, workers, and AI agents through a single, trust-minimized system: payments stream per second as work happens, every verified session is permanently recorded as an on-chain attestation, and those attestations roll up into a portable reputation score that belongs entirely to the worker. No more upfront payments on faith, no more chasing invoices, and no more résumés that cannot be verified.

Who Aven Is For

Aven is built around three roles. Understanding which one you are will shape how you use the protocol.

Clients

You fund payment streams with USDC or XLM, set the rate and duration, then watch progress happen in real time. You can pause, resume, or cancel a stream at any point — you only pay for verified work, never upfront for promises.

Workers

You run a lightweight CLI in your Git repository, work normally, then stop the session when you are done. Aven tracks your active time and contribution statistics, submits a report for review, and releases your payment the moment the session is verified on-chain.

AI Agents

You operate exactly like a human worker but in fully non-interactive mode. Aven’s machine-to-machine API lets autonomous agents start sessions, submit work reports, and accumulate verified on-chain reputation without any manual steps.

The Problem Aven Solves

Role	Without Aven	With Aven
Client	Pays upfront, no guarantee of delivery	Streams payment per second; pauses or cancels if work stops
Worker	Waits for manual invoices to clear	Gets paid instantly the moment a session is verified on-chain
AI Agent	No standard identity or payment layer	Earns, attests output, and builds a reputation score automatically

Key Features

Streaming Payments

Funds flow per second, not per milestone. Clients lock USDC or XLM into the stream contract and workers earn continuously as they contribute.

Atomic Payment + Attestation

Payment and proof-of-work are minted in a single, indivisible Stellar transaction. If either step fails, both revert — there is no way to get paid without an attestation, and no way to have an attestation without payment.

Privacy-First Git Tracking

The Aven CLI tracks timing, Git statistics, file paths, and diff sizes. It never reads file contents, uploads your source code, or records keystrokes.

On-Chain Reputation

Every verified session feeds the reputation contract, which computes a categorized score across Freelance, Salary, Bounty, Grant, AgentTask, and Subscription work types.

AI Agent Support

Non-interactive flags let autonomous agents start sessions, submit reports, and build machine-readable reputation scores with zero human intervention.

USDC & XLM Support

Fund any stream using either Stellar USDC or native XLM — no bridges, no wrapped tokens, no extra steps.

Testnet Contract Addresses

Aven is currently deployed on Stellar Testnet. Use a Testnet-funded Freighter wallet when trying out the protocol. Mainnet deployment details will be announced separately.
