Lemondrop: Stack Bitcoin Passively While Using Solana
For most people, saving Bitcoin is something they have to do intentionally—set reminders, track price swings, move stablecoins around, and so on. Lemondrop flips that idea on its head. It turns your everyday activity on Solana into an automatic Bitcoin savings plan.
What Is Lemondrop?
Lemondrop is a lightweight browser extension that rounds up your Solana transactions and converts the spare change into Bitcoin. Think of it like Acorns for crypto—but instead of sending your spare change to a stock ETF, it goes into BTC.
You install it in Chrome, Brave, or Firefox, connect your Solana wallet, and that’s it. From there, every swap, mint, or purchase you make on Solana gets rounded up, and that extra bit gets swapped into wrapped BTC. It all happens automatically.
Why It’s Different
Most DeFi products are built around speculation—tokens, farming, boosting yields. Lemondrop isn’t. It’s a tool, not a casino.
What makes it stand out is its simplicity and practicality. There’s no dashboard with 12 tabs, no token rewards, no artificial inflation. You just use Solana like you normally would, and quietly accumulate BTC in the background. It doesn’t try to become your new wallet or replace your entire stack—it just adds one useful layer on top.
And importantly, Lemondrop doesn’t collect your data or move your funds. Everything is handled on-chain, and your wallet stays in your control.
Funding & No Token
Lemondrop completed a seed funding round in early 2025, backed by Bitcoin-focused and crypto-native investors like EPOCH, CoreDAO, Rootstock Labs, and Sats Ventures.
Notably, there’s no token involved. There’s nothing to buy, no airdrop to farm, and no speculative mechanics built in. The entire business model is based on a small fee (~1%) on round-up conversions. It’s clean, transparent, and product-driven.
How the Fees Work
Lemondrop charges a 1% platform fee on each round-up. That’s on top of standard swap fees from Jupiter or bridging costs via Atomiq, depending on how you use it. The fee goes to a fixed public address, so anyone can verify it on-chain.
There are no subscriptions or hidden costs. You only pay when you round up—and you control how often that happens.
Who’s Behind It?
The team behind Lemondrop also runs “Bitcoin Layers,” a tracker focused on Bitcoin L2s, bridges, and wrapped BTC across chains. They’ve been in the BTC-on-alt-L1s space for a while, and this product is a natural evolution of that work—making wrapped BTC actually useful for everyday users.
Is It Worth Using?
If you’re already active on Solana, Lemondrop offers a passive, low-friction way to start stacking BTC. It’s not a yield farm, and you’re not going to see huge APYs—but it’s reliable, simple, and doesn’t require effort.
For light users or people doing a few transactions a month, it may not make a big dent. But if you’re constantly interacting with Solana apps, this is an easy way to build a Bitcoin position over time without even thinking about it.
