Terms of Service

What Mercato is

Mercato is a community-built consumer-price index on the Celo blockchain. Anyone can submit a local price for an everyday product. Other contributors vote ✓ or ✗ on submissions. After three matching positive votes the submission is finalized and stored on-chain as a price observation. The full source code is MIT-licensed and lives at github.com/BRN-SLP/mercato.

No warranties

Mercato is provided as-is, with no warranties of any kind. The smart contract is immutable in its current logic: its source is verified on Celoscan so you can inspect it before interacting. You are responsible for any transaction you submit. We make no claim that any submitted price is accurate; consensus only proves that three peers agreed, not that the price reflects reality.

Rewards

The contract pays small cUSD rewards to submitters and verifiers from a fixed seed pool funded by the project. The pool is finite. When it is depleted, the reward-distribution path inside the contract will revert with InsufficientPoolBalance; submissions and verifications still work but no payouts occur. There is no guarantee of any specific reward amount or payout schedule.

Acceptable use

• Submit prices you have actually observed. Spam, fraudulent or coordinated submissions are not welcome and will be voted down by the community.
• Do not attempt to attack, overload, or game the contract or this site. Security disclosures: open an issue on the GitHub repo above.
• All submitted price observations become public on-chain data the moment they are mined. Treat anything you publish as permanent and public.

Open data

All price observations submitted via Mercato are released into the public domain (CC0). Anyone can read, copy, fork, or build on the data: that is the entire point of the project.

Changes

These terms may change as the project evolves. The current version is always the one served at this URL.
