It tracks your group's holdings, any loan, and a safety score — plain numbers, updated in real time.
Hold Bitcoin together, with rules you all signed.
BTC Pact is where a small group writes its shared Bitcoin plan, signs it, and votes on every change — your coins never leave your wallets.

the foundation
money that no one can print more of.
Bitcoin is the first asset whose supply is not someone else's policy decision. Twenty-one million units, no exceptions, no committee. Every block since 2009 has anchored the count.
A group holding Bitcoin together is not just a position. It is a relationship with a network whose terms cannot be renegotiated.

beyond holding
holding is a position. a Pact is a discipline.
Most people who hold Bitcoin with others have no written plan: nothing that says who decides, what happens in a bad week, or how to prove later what everyone agreed. BTC Pact turns that into one signed agreement.
the basics
what fortress does.
seals
Your signed agreement gets a tamper-proof timestamp in Bitcoin's public record. BTC Pact proves what your group agreed — your coins stay where they are.
records
Every vote is recorded as a signature that can't be forged, so no one can quietly rewrite what was agreed.
shares
Each day ends in a report you can share as a link — anyone you send it to reads exactly what the group saw.

is the holding at risk?
Current LTV is below the warning line, but the forecast cone touches the top-up zone under stress. The holding is not in immediate danger; the next disciplined move is to pre-agree a collateral response before volatility decides for the group.
