Why TapVault?
The most advanced Bitcoin escrow platform, built for security and flexibility.
Non custodial
Your keys never leave your browser. Private keys are encrypted locally with AES-256 and your signing password.
Automatic timelock refund
Built in CSV timelock lets the buyer reclaim funds automatically after a configurable period no arbitrator needed.
2-of-3 Taproot multisig
Every escrow creates a Taproot address with buyer, seller, and arbitrator keys. Two signatures required to move funds.
Instant setup
Create an escrow in 60 seconds. Share an invite link. Counterparty joins from any browser no app install needed.
On chain privacy
Taproot MAST hides unused spend paths. Completed escrows look like normal Bitcoin transactions to outside observers.
Self hosted SaaS
Deploy on your own server. White-label branding, custom templates, Stripe subscriptions. You own the platform.
How It Works
Four steps to a secure Bitcoin transaction
Create escrow
Choose a template, set the amount and conditions. Share the invite link with your counterparty.
Fund the address
Both parties verify the Taproot address. Buyer sends BTC. Funds are locked in a 2-of-3 multisig.
Deliver & release
Seller delivers the goods/services. Buyer approves and co signs the release. Funds sent to seller.
Dispute? Arbitrator decides
If there's a disagreement, the platform arbitrator reviews evidence and co signs with the winning party.
