DeFi
Hubric Node provides a set of DeFi-focused smart contract templates that enable users to deploy common decentralized finance primitives without writing code. These templates are built from modular nodes and designed to be configurable, composable, and production-ready for EVM networks.
The DeFi layer of Hubric Node is aimed at supporting the most common token utility mechanisms required by Web3 projects, including staking, fundraising, distribution, and trust-minimized transactions.
5.2.1 Token Staking Template
The Token Staking Template enables projects to incentivize long-term holding by allowing users to lock tokens and earn rewards based on time and allocation.
Core Capabilities
Stake and unstake functions with configurable rules
Reward distribution logic (time-based accumulation)
Optional lock duration and penalty mechanism
Pool-level configuration for multiple staking campaigns
Transparent on-chain accounting (total staked, rewards claimed)
Configuration Parameters
Staking token address (ERC20)
Reward token address (ERC20)
Reward rate model (fixed rate / per-block / per-second)
Start time and end time (optional)
Minimum and maximum stake amount (optional)
Lock period duration (optional)
Early unstake penalty (optional)
Claim interval / claim anytime (optional)
Admin controller (EOA / MultiSig)
User Flow
User deposits staking tokens into the pool
Rewards accumulate based on configured rate model
User claims rewards periodically or at the end
User unstakes after lock period (or earlier with penalty, if enabled)
Use Cases
Utility enhancement for ERC20 tokens
Long-term holder incentives
Liquidity bootstrapping support (paired with LP staking in future expansions)
Community loyalty programs
5.2.2 Crowdfunding Template
The Crowdfunding Template enables decentralized fundraising campaigns with transparent tracking and programmable fund release conditions.
Core Capabilities
Campaign creation with target amount and deadline
On-chain contribution tracking per address
Success/failure outcomes based on campaign rules
Fund withdrawal logic for project owner after success
Refund logic for contributors if campaign fails
Configuration Parameters
Funding token (native token or ERC20)
Target amount (soft cap / hard cap options)
Campaign start and end time
Receiver wallet (project treasury)
Refund policy (enabled/disabled; automatic/manual)
Contribution limits (min/max per wallet)
Whitelist participants (optional)
Admin controller (EOA / MultiSig)
Campaign Outcomes
Successful Campaign: funds become withdrawable by the project treasury
Failed Campaign: contributors can claim refunds (if enabled)
Use Cases
Seed funding for community projects
Transparent fundraising for DAOs
Launchpad-like community sales (basic version)
Funding rounds with defined milestones (expandable by node composition)
5.2.3 Escrow Template
The Escrow Template provides a trust-minimized mechanism for conditional payments between two parties, optionally including an arbiter or multi-party approval.
Core Capabilities
Funds are locked in escrow until conditions are met
Configurable release rules (buyer approval, delivery confirmation, time-based release)
Optional dispute resolution / arbiter controls
Supports ERC20 and native transfers (depending on configuration)
Transparent lifecycle of each escrow transaction
Configuration Parameters
Asset type (native / ERC20)
Buyer and seller addresses
Arbiter address (optional)
Approval requirements (2-party / 3-party)
Release conditions (manual approval, time-based, milestones)
Expiry time (optional)
Admin controller (EOA / MultiSig)
Use Cases
Marketplace payments
Service-based transactions
OTC token trades
Partnership payments requiring conditions
5.2.4 Token Airdrop Template
The Token Airdrop Template enables batch distribution of ERC20 tokens across multiple addresses while providing transparent accounting and distribution controls.
Core Capabilities
Batch token distribution to multiple addresses
Gas-aware execution strategy (batched operations)
Support for fixed allocations per address
Distribution tracking and verifiability
Optional time window and claim-based distribution models (expandable)
Configuration Parameters
Token address (ERC20)
Distribution list (addresses + amounts)
Total distribution cap (optional)
Distribution mode (direct send / claim-based in later versions)
Start and end time (optional)
Admin controller (EOA / MultiSig)
Use Cases
Community incentives and rewards
Marketing campaigns
Early adopter allocations
Partner distributions
5.2.5 DeFi Composability (Node-Based Design)
A key advantage of Hubric Node’s DeFi layer is composability. DeFi templates can be combined into larger systems through node integration.
Example compositions:
ERC20 Token + Staking → token utility + retention
Crowdfunding + Airdrop → fundraising + post-campaign distribution
MultiSig + Treasury + Staking Rewards → secure administration of rewards pool
Voting + Crowdfunding → community governance over fundraising allocation (future-ready)
This modular approach allows projects to scale their DeFi functionalities over time without rebuilding from scratch.
5.2.6 Security Considerations (DeFi Layer)
Hubric Node’s DeFi templates are designed with security-first principles:
Access control isolation: administrative actions restricted to owner or MultiSig
Parameter validation: prevents common misconfiguration risks (invalid token address, zero rates, incorrect time windows)
Safe transfer patterns: standardized token transfer logic to reduce ERC20 edge-case failures
Event logging: standardized events for transparency and indexing
Reduced attack surface: modular nodes avoid large monolithic contracts
Future upgrades (planned):
Audit-ready releases for each node family
Formalized testing and standardized deployment checks
Optional circuit breakers (pause / emergency withdraw) where appropriate
5.2.7 Summary
Hubric Node’s DeFi templates provide essential primitives for token utility, fundraising, secure transactions, and community distribution. By packaging these systems as modular and configurable nodes, Hubric Node enables projects to launch DeFi functionality faster, safer, and with significantly lower operational complexity.
