Overview

Aven is built from four cooperating layers. Each layer has a single responsibility and communicates with the next through well-defined boundaries — a signed transaction, a JSON payload, or a contract invocation.
1

Client layer

The dashboard (web app) and the aven-stellar CLI. Clients create streams, workers track sessions.
2

Protocol layer

Three Soroban smart contracts: Stream, Attestation, and Reputation.
3

Settlement layer

The Stellar network — Testnet today, Mainnet at launch.
4

Identity layer

Freighter (or any Stellar wallet) signs every state-changing transaction.

Data flow

  1. A client funds a Stream contract in USDC or XLM.
  2. A worker runs aven-stellar start, which reads local Git activity and produces a signed session report.
  3. aven-stellar stop submits the report to the Stream contract.
  4. The Stream contract releases funds and invokes the Attestation contract in a single atomic transaction.
  5. The Reputation contract reads all attestations for a given address on demand.

Trust model

  • No custodial servers. Aven never holds keys or funds.
  • Atomic payout + proof. Payment and attestation succeed or fail together — there is no state where one exists without the other.
  • Portable identity. A worker’s reputation is derived entirely from on-chain attestations tied to their Stellar address.
