The Problem

RWA Tokens Are Illiquid

Tokenized real-world assets face three critical infrastructure gaps that prevent adoption.

×

No Exit Liquidity

RWA token holders are stuck. No buyers, no market makers, no way to convert back to stablecoins. Assets become digital dead weight.

×

AMM Slippage

Traditional DEXs impose x*y=k price impact. Selling $100k of RWA tokens on Uniswap V3 could mean 5-20% slippage loss.

×

No Liquidation

When RWA assets face distress, there is no orderly exit mechanism. No LPs, no penalty pricing, no risk-adjusted fills.

The Solution

Dobprotocol Pipeline

Three specialized layers working together. DobDex is the final liquidity piece.

Token Selected

DCT (Datacenter Token) — Oracle: $100

2

Depositing to Vault

10 DCT → DobRwaVault

Oracle Query

DobValidatorRegistry.getPrice(DCT) = $100.00

beforeSwapReturnDelta

Hook intercepts — NoOp skip AMM. 10 × $100 = 1,000

5

dUSDC Minted

1,000 dUSDC settled to user. Zero slippage.

Liquidation Engine

Distressed Asset Liquidation

AI-detected distress triggers orderly LP-backed fills with risk-adjusted pricing.

AI Distress Detection ALERT

Dobprotocol AI validator detects distress signal on SFT (Solar Farm Token). Asset flagged for liquidation review.

Penalty Rate Set CONFIGURED

Liquidation penalty: 20% (2000 bps)
Risk assessment reflects 20% probability of further value loss.

LP Matched — FIFO

LP1 conditions check: minPenaltyBps 15% ≤ 20% ✓
LP1 USDC allocation is sufficient for this fill.

Fill Executed FILLED

LP1 provides 8,000 USDC → receives 10,000 dUSDC worth of SFT
Spread profit: 2,000 dUSDC (25% return)

Reserve Hold

33% reserve: 2,640 USDC locked for 24h
MIN_BACKING_AGE enforced. Prevents flash-liquidation attacks.
