Staking Service Overview

Signature Verification

User operations (presaleStaking, publicStaking) use Core.sol's centralized verification via validateAndConsumeNonce(). All staking signatures follow the universal EVVM format with StakingHashUtils for hash generation.

The Staking service is a dual-contract system enabling users to stake MATE tokens and receive time-weighted rewards for participating as network fishers.

Architecture​

  • Staking Contract: User operations, access tiers, and governance
  • Estimator Contract: Epoch-based reward calculations with time-weighted algorithms

Key Features​

Multi-Tier Access​

  • Golden Staking: Exclusive golden fisher access with EVVM nonce sync
  • Presale Staking: 800 presale users, maximum 2 staking tokens each
  • Public Staking: Open access when enabled
  • Service Staking: Three-phase process (prepare → pay → confirm) plus direct unstaking

Security & Economics​

  • Centralized Verification: Core.sol validates all user operations
  • EIP-191 Signatures: Cryptographic authorization with originExecutor (EOA verification)
  • Nonce Management: Core async nonces for universal replay protection
  • Time-Delayed Governance: 24-hour administrative changes
  • Time-Locked Unstaking: 5-day waiting period for full unstaking (configurable)
  • Fixed Price: 1 staking token = 5,083 MATE tokens
  • Enhanced Rewards: 2x rewards for stakers validating transactions

Reward System​

  • Epoch-Based: Time-weighted calculations ensuring fair distribution
  • Proportional: Rewards based on staking duration and amount
  • Mathematical Precision: Sophisticated algorithms for accurate reward allocation
