Sigmund’s Sat Stacker is a personal BTC-yield vault on the Base chain, created by [Sigmund Vexler](Sigmund Vexler) via the 0x3288…9b1a wallet on 2025-03-27. Built using DexFi, it launched with a projected APY of ~42%, sourced entirely from swap fees on Aerodrome—not emissions.
Description:
80% BTC, 20% USDC. Designed to farm stablecoin swaps and auto-compound yield into more Bitcoin—quietly, forever.
Allocation
- 60% tBTC/cbBTC (Aerodrome CL, 0.01%)
- 25% USDC/cbBTC (Aerodrome CL, 0.05%)
- 15% tBTC/USDC (Aerodrome CL, 0.30%)
Cumulative exposure: 80% BTC, 20% USDC
USDC is used purely as yield-fuel—never as a hedge.
Strategy
This vault is designed to act as a BTC accumulator, not a generic yield farm.
- Yield is generated from concentrated liquidity swap fees on Aerodrome.
- Earnings are auto-compounded across the vault to maintain the fixed USD-denominated allocation.
- This causes overperformance in stable-heavy pairs to be rebalanced into BTC-heavy pools over time.
- The result is slow, reliable BTC stacking—without ever compromising core exposure.
Performance Fee:
5.5% of yield is taken as performance fee—1% to Sigmund Vexler, 4.5% to DexFi protocol.
