Budgeting and Finance Administration

Author: Cateatpeanut, with input from the Mantle Core Contributor Team and service providers

Tags: Budgeting, Finance, Administration


This document outlines the best practices for finance administration processes between the Mantle Core Budget and authorized Service Providers. The first iteration was the BIP-19 proposal.

Accounting Method

  • Multicurrency: For the purposes of monthly claims, each major asset including MNT, USDT, USDC, ETH shall be accounted for in units. This provides simplification for end of period FX treatments.

  • Invoicing and payment cycle: Each authorized Services Provider shall invoice the Core Operations Budget after the end of each month, by the 20th of the month. Qualified payments will be made within 1 week to the onchain address. For 1-2 months working capital, service providers can request working capital financing.

  • Record Keeping: Service Providers shall maintain standard accounting systems, general ledger, and records of payments and costs for the purposes of review by the Mantle Administrator, or future nominated reviewers.

  • Accrual accounting: Revenue is recognized in the period in which it's earned and realizable, but not necessarily when the cash is actually received. Revenues and expenses are recognized in the same period.
