Hodlr

Inspiration

I've tried to save in Bitcoin more times than I can count. Every time, the Nigerian economy wins. I buy a small amount, tell myself this is the one I'm keeping, the one I don't touch. Then Rent goes up. Data prices jump. A family obligation shows up at the door unannounced. And just like that, I'm on P2P converting my stack back to naira to cover something that couldn't wait.

It's not a weakness. It's arithmetic. When your local currency loses value faster than your salary grows, your Bitcoin stops being a long-term investment and starts being an emergency fund, whether you want it to or not. The frustrating part is that I know what Bitcoin is supposed to be. I know the thesis. I believe it. But belief doesn't pay a generator bill or cover school fees when the month runs longer than the money.

I kept asking myself one question: what if the option to sell simply didn't exist? What if Bitcoin were mathematically, cryptographically, irreversibly out of reach, until a date I chose, years from now? That question became Hodlr.

What it does

Hodlr lets you lock Bitcoin to a future date — 1 year, 10 years, 30 — and walk away with mathematical certainty that you can't touch it early.The lock countdown is enforced on-chain in a production version via OP_CHECKLOCKTIMEVERIFY (CLTV) — a Bitcoin Script opcode that makes coins literally unspendable until a target block height or timestamp is reached. No company. No override button. No early withdrawal. Just you, your keys, and time.

Challenges we ran into

Some of the challenges we ran into were realizing that sometimes 10 years might really be a long time, and some users might not be comfortable with it, so we created a long-term save and a short-term save option that users can choose from.
