How Does Tropykus RSK Work?
Tropykus RSK, a Compound v2 fork on the RSK Bitcoin sidechain, announced a full protocol wind-down on April 27, 2026. The web interface closed July 27, 2026, and smart contract technical support ends September 1, 2026. The shutdown was triggered by a Money on Chain security audit that identified vulnerabilities in immutable deployed contracts that cannot be patched. TVL has fallen ~97% to approximately $180K as users withdrew following the announcement. Remaining depositors should withdraw immediately via direct contract interaction before the September 1 decommission deadline.

Core Mechanisms
6.1.1
Compound v2 fork on RSK — over-collateralized lending with cToken receipt tokens for rBTC, RIF, rUSDT, DOC
Standard Compound architecture adapted for RSK network assets
6.2.2
Algorithmic interest rates based on real-time supply and demand via Compound-style utilization curve
Standard kinked utilization curve for setting borrow/supply rates
6.3.2
Fixed-spread liquidation — standard Compound v2 liquidation with incentive bonus
Liquidators receive bonus for closing undercollateralized positions
5.1.1
TROP token governance with proposals, timelock, and voting on protocol parameters
Standard Compound Governor+Timelock governance pattern
6.4.1
Oracle price feeds for RSK native assets (rBTC, RIF, rUSDT, DOC)
Price feeds for RSK ecosystem assets used for collateral valuation
How the Pieces Interact
Limited liquidator ecosystem on RSK means liquidations may be slow during market stress — thin liquidity amplifies bad debt accumulation risk
Low utilization from small user base may keep rates below sustainable levels, while sudden utilization spikes could trap borrowers at extreme rates
TROP governance with potentially concentrated voting power could adjust risk parameters without sufficient community scrutiny
RSK ecosystem oracle infrastructure may be less robust than Ethereum-based alternatives, with fewer redundancy options for price feeds
What Could Go Wrong
- Protocol in full wind-down — web interface closed July 27, 2026 and smart contract support ends September 1, 2026; remaining depositors must withdraw directly via contract or risk indefinite fund lockup
- Security audit by Money on Chain identified unpatched vulnerabilities in immutable deployed contracts — team chose full shutdown over remediation, confirming unfixable security flaws remain in active contracts until September 1
- TVL collapsed ~97% to ~$180K following April 27, 2026 shutdown announcement — near-zero liquidity means remaining depositors face significant withdrawal friction
- July 2023 exploit on custom rBTC micro market lost ~10% TVL via exchange rate manipulation; a separate vulnerability class was later discovered in the same immutable system, triggering the 2026 shutdown
RSK Liquidation Failure During Market Crash
ModerateTrigger: Sharp market downturn overwhelms RSK's limited liquidator set, causing bad debt accumulation across lending pools
- 1.Rapid rBTC price decline triggers liquidation thresholds across multiple borrowers — Liquidation queue builds faster than available liquidators can process
- 2.RSK network's thin DeFi liquidity means liquidators cannot efficiently sell collateral — Bad debt accumulates as liquidations become unprofitable
- 3.Lenders attempt to withdraw but utilization is at maximum — Withdrawal impossible; interest rates spike but funds remain locked
- 4.Protocol bad debt socialized across all lenders — Depositors face permanent loss of a portion of their deposits
