Core Concepts and Terminology

Self-Custody in Finance

Self-custody represents a fundamental shift in financial control. Instead of trusting a bank or institution to hold your assets, you maintain direct control of your private keys—essentially becoming your own bank. This distinction is critical:

Custodial Solutions

  • Third party controls your assets
  • Requires trust in the institution
  • Subject to institutional policies
  • May freeze or restrict access
  • Usually easier for beginners

Non-Custodial Solutions

  • You control your private keys
  • No third-party trust required
  • Freedom from institutional restrictions
  • Full access to your assets at all times
  • Requires personal security responsibility

With self-custody comes responsibility. You must implement appropriate security measures and backup procedures to protect your assets. However, modern tools like multi-signature wallets have made self-custody both more secure and more accessible.

Ecosystem Economics

GNO Token Utility and Economics

The GNO token serves multiple functions within the ecosystem:

  • Ecosystem governance - GNO holders can participate in governance decisions
  • Value accrual - benefits from increased adoption of Gnosis Pay and ecosystem components
  • Limited supply dynamics - creates positive pressure on token value

The economic model ensures long-term viability while minimizing user costs:

  • Low gas fees on Gnosis Chain compared to Ethereum mainnet
  • One-time card cost of approximately €30 with minimal ongoing fees
  • Zero-fee transfers between Monerium accounts
  • Competitive advantage over traditional banking costs

Security Considerations

Self-Custody Responsibilities

With self-custody comes important security responsibilities:

  • Private key management - implement secure storage solutions
  • Backup procedures - create and securely store recovery phrases
  • Phishing awareness - be vigilant against social engineering attempts
  • Regular security audits - periodically review access controls

Hardware Security Enhancement

Ledger hardware wallets provide an additional security layer:

  • Air-gapped signing - private keys never leave the device
  • Physical verification - transactions confirmed on secure display
  • Safe integration - hardware wallet added as an owner
  • Recovery mechanisms - backup options if device is lost

Multi-Signature Security Model

The Safe wallet's multi-signature capabilities form the security foundation:

  • Configurable thresholds - determine how many approvals are required (e.g., 2-of-3)
  • Owner management - carefully select trusted additional signers
  • Emergency access planning - create contingency for urgent situations
  • Audited smart contracts - benefit from Safe's proven security model
