Summary

Building on the recently approved Asset Expansion Strategy (proposal #5864, passed with unanimous Yes votes at 23.66m voting power, quorum achieved), this RFC proposes optional xSAUCE RWA Yield Vaults - automated, DAO-managed vaults allowing xSAUCE holders to voluntarily allocate a portion (0-50% slider in the SaucerSwap Wallet/app) of their position to tokenized U.S. T-bill money market funds (MMFs) already live on Hedera via partners like Archax (e.g., BlackRock ICS, abrdn, Swarm, State Street, LGIM tokenized MMFs).

The vaults deliver:

  • Continued base xSAUCE auto-compounding from SaucerSwap DEX fees + HBAR rewards + buybacks on the full position.

  • Additional stable real-world yield (~3-4% APY, depending on prevailing short-term rates, accruing as NAV or redeemable tokens) on the allocated portion.

  • A small 0.5% performance fee on vault AUM, automatically swapped to SAUCE and routed back to the DAO treasury/Infinity Pool for further buybacks (benefiting all xSAUCE holders).

This leverages Hedera’s native Token Service, Asset Tokenization Studio, and the Wyoming DUNA wrapper to create the first DEX receipt token in DeFi with native institutional-grade RWA yield - transforming xSAUCE into a hybrid crypto + TradFi bearer instrument, fully aligned with the Asset Expansion focus on RWAs as a high-growth priority.

Motivation

The Asset Expansion Strategy enables proactive onboarding of RWAs (explicitly naming BlackRock’s BUIDL, Ondo’s USDY/OUSG, and similar tokenized treasuries), seed liquidity, and partner co-liquidity to build durable TVL ahead of V3. This RFC extends that foundation by proposing a direct, user-facing product that captures and layers RWA yield onto xSAUCE - addressing holder demand for stable real-world returns without exiting positions.

Hedera already leads in live RWA infrastructure (Archax tokenized MMFs from major asset managers on mainnet since 2024-2025, Kaio $3B+ funds, RedSwan $2.2B+ CRE). We are productizing existing assets, not building from scratch.

  • xSAUCE currently offers strong but crypto-volatile compounding; many holders seek stable yield overlays.

  • No equivalent exists on Uniswap or major DEXes - this creates a clear moat.

  • Post-DUNA + recent governance realignments, the DAO can responsibly handle real-world yields.

  • Attracts institutions and retail users wanting “crypto upside with T-bill safety” → significant DAU/TVL growth post-V3.

Real-World Use Cases

Retail User - The Everyday HBAR Holder
Alex, a long-time Hedera supporter, stakes his SAUCE into xSAUCE via the Infinity Pool ($14,500 position compounding from fees/rewards/buybacks). With vaults live, he allocates 30% ($4,350) via a simple slider. That slice converts to tokenized MMF shares (BlackRock/State Street/Swarm/etc.), earning extra ~3-4% stable APY as accruing NAV. Full position keeps base compounding; DAO’s 0.5% fee boosts buybacks slightly for everyone. One-tap instant redeem to xSAUCE + accrued yield, sub-second finality. Set-it-and-forget-it upgrade: crypto growth + T-bill stability.

Institutional User - Family Office Treasury
A $280M family office with $2.1M in xSAUCE allocates 40% ($840,000) to the vault. They gain predictable T-bill yield on the slice (via regulated tokenized MMFs), instant on-chain settlement/audit trails, DUNA compliance, and indirect upside from performance-fee buybacks. Turns idle capital into a compliant, liquid treasury tool with DeFi exposure - prompting expanded Hedera allocations.

Specification & Rationale

1. Vault Mechanics

  • Single-sided xSAUCE deposit into vaults via SaucerSwap Wallet/dashboard.

  • User selects allocation %; allocated portion auto-converts (via integrations/partnerships) to tokenized MMF shares.

  • Base xSAUCE compounding on full position; RWA yield accrues on allocated slice.

  • Instant one-click redeem to xSAUCE + accrued MMF yield.

2. Yield & Fee Structure

  • RWA yield: Matches underlying MMF (~2.5-4%+ APY, accruing/claimable).

  • DAO performance fee: 0.5% annual on vault AUM → swapped to SAUCE for buybacks.

  • No new emissions; backed by real T-bill interest + protocol revenue.

3. Technical Stack

  • Hedera Token Service + Asset Tokenization Studio.

  • Archax/similar partner integrations (already live).

  • EVM/native smart-contract vault with DUNA wrapper for optional KYC lanes.

  • Mobile UI with yield dashboard and auto-rebalance alerts.

  • Initial treasury seed: Modest, capped allocation (~5-10% of current treasury) for bootstrapping, recoverable via fees.

4. Phased Rollout

  • Phase 1: Single vault with primary MMF basket.

  • Phase 2: Multi-vault options + institutional features.

Benefits

  • xSAUCE holders: Extra stable yield + indirect buyback boost → longer holds, tighter float.

  • New users/DAU: Institutions/retail enter via T-bills, stay for SaucerSwap ecosystem.

  • Ecosystem: Positions SaucerSwap as Hedera’s RWA yield hub → more TVL/fees → accelerated xSAUCE compounding.

  • DAO: New recurring revenue without supply changes.

Downsides & Mitigations

  • Smart-contract risk: Top audits, time-locks, insurance from fees.

  • Regulatory/partner reliance: Uses live, regulated MMFs + DUNA.

  • Yield variability: Transparent display; fully voluntary allocation.

  • Opportunity cost: 0% allocation option anytime.

Feedback Requested

Community and especially SaucerSwap Labs input is highly valued to ensure this proposal is technically viable, aligns with the protocol roadmap (including V3 and any upcoming integrations), and has strong support potential.

Please share:

  • General support / suggestions / concerns

  • Preferred initial MMF partner or yield target (e.g., specific BlackRock ICS vs. multi-manager basket)

  • Max allocation % you’d personally consider using

Direct questions for SaucerSwap Labs:

  • Is this concept technically feasible with current/existing integrations (e.g., Tokenized MMFs, Hedera Token Service, Asset Tokenization Studio)? Any major blockers or prerequisites?

  • Does this align well with the Asset Expansion Strategy implementation roadmap, and are there any treasury, fee-switch, or governance implications to consider early?

  • Any recommended adjustments to the performance fee structure, initial treasury seed, vault mechanics, or phased rollout to improve viability and reduce risks?

Feedback here will help refine the proposal. Thank you in advance, this could be a powerful extension of the RWA momentum from the recently passed strategy.
