How It Works

Four steps to protect
a lifetime of stacking.

No lawyers. No custodians. No single point of failure. Just Clarity contracts secured by Bitcoin.

01

Connect & Deposit

Connect your Xverse or Leather wallet and deposit sBTC into your LastSats vault. You remain in full control.

02

Configure Beneficiaries

Set wallet addresses, percentage splits, and optional time-locks. Add a guardian who can pause execution if needed.

03

Set Your Heartbeat

Choose how often you check in — every 30, 60, or 90 days. A single transaction confirms you're alive.

04

Automatic Execution

If your heartbeat is missed and the grace period expires, the Clarity smart contract distributes your sBTC automatically.

Built for the long-term HODLer.

Every feature designed around one goal: your Bitcoin reaches your family.

Non-Custodial

LastSats never holds your keys or your Bitcoin. Ever.

Bitcoin-Secured

All state is anchored to Bitcoin via Stacks. Immutable.

Automatic Execution

Clarity smart contracts execute without any human intervention.

Time-Locks

Release funds to heirs at a specific age or date.

Multi-Beneficiary

Split your vault across unlimited heirs with custom percentages.

Guardian Role

Assign a trusted contact to pause execution if something goes wrong.
