Horizon - Lending Markets
The core savings and yield engine of Surf
The Horizon Strategy is Surf’s primary capital deployment engine for stable, risk-aware yield. It is designed to behave like an automated treasury manager, not a speculative trading system.
Its goal is simple:
Maximise sustainable, risk-adjusted yield while preserving liquidity, safety, and exit optionality at all times.
What Horizon Optimises For
Horizon is built around four primary objectives:
Capital Preservation First
Yield is secondary to safety. No strategy is allowed to increase liquidation risk, protocol concentration, or exit fragility in order to chase headline APY.
Net Yield, Not Nominal Yield
The system optimises for:
APY after fees
After slippage
After gas
After incentive decay
After withdrawal and unwind costs
Liquidity and Exit Readiness
Funds must always be positioned where:
Withdrawals can be processed quickly
Liquidity is deep
Market stress does not trap capital
Deterministic Risk Boundaries
Every allocation is constrained by:
Exposure caps
Venue risk scores
Correlation limits
Health factor buffers
Stress scenario tolerance
How Horizon Thinks About Yield
Horizon does not treat yield as a single number. It models yield as a dynamic system influenced by:
Utilisation curves
Borrow demand
Incentive emissions and cliffs
Liquidity depth
Volatility regimes
Correlated liquidation risk
Protocol upgrade and governance risk
Oracle and price feed integrity
Each venue is continuously scored on:
Base rate sustainability
Incentive stability
Liquidity resilience
Historical stress behaviour
Smart contract and governance risk
Strategy Universe
Horizon operates across:
Lending and borrowing markets
Liquidity provisioning venues
Incentivised pools
Cross-chain yield sources
Only allowlisted, audited, and monitored protocols are considered. Each protocol is placed into a risk tier with strict allocation ceilings.
Allocation Logic
At any moment, Horizon decides:
How much capital to allocate
To which venues
In which asset combinations
With what buffer to liquidation
With what withdrawal latency tolerance
The strategy explicitly avoids:
Single-venue concentration
Incentive cliff exposure
Thin liquidity pools
Reflexive loops that amplify liquidation cascades
Rebalancing Philosophy
Horizon does not rebalance continuously.
Rebalancing is triggered only when:
Risk-adjusted return improves materially
Liquidity and exit safety remain strong
Execution cost is justified
Guardian constraints are fully satisfied
Small APY differences are ignored. Stability and continuity are prioritised.
Stress and Downside Handling
Horizon continuously simulates:
Rate collapses
Liquidity drains
Oracle deviations
Borrow utilisation spikes
Incentive exhaustion
Cross-asset correlation shocks
When risk rises:
Exposure is reduced
Liquidity buffers are increased
Allocation is shifted toward more resilient venues
Rebalancing frequency is throttled
Why Horizon Is Different
Most yield systems optimise a spreadsheet. Horizon optimises a live, adversarial system.
It combines:
AI-driven opportunity scanning
Deterministic risk constraints
Continuous stress simulation
Non-custodial execution
User-owned vault isolation
Guardian-enforced safety rules
The result is not “maximum APY at any cost”.
It is:
Sustainable, compounding yield that can be trusted with long-term savings.
This is why Horizon behaves like a programmable savings engine, not a farming bot.
