The Problem with Traditional Trust

Crypto without a wallet?

Sending crypto to someone who doesn't have a wallet yet? Hope they figure it out before you need those funds back.

Crypto inheritance?

Want your family to inherit your crypto if something happens? Good luck explaining private keys to your loved ones.

Trust the other party?

Making a payment or deal? Either trust the other party completely, or risk losing everything.

Lockd removes trust from the equation.

Three Ways to Lock Value

Send crypto with automatic refund protection. Set a deadline—recipient claims or you get it back. Perfect for freelance work, bounties, gifts, and P2P deals.

Lockd Inheritance

Freelance Payments

Lock payment for a designer or developer. They claim when work is delivered. If not delivered, refund after deadline.

Example: Pay 500 USDC for a logo design

Bounties & Rewards

Lock a bounty for whoever fixes a bug or completes a task. Assign it to the contributor who delivers.

Example: 1 ETH bounty for security audit

P2P Offers

Make a trustless offer for an NFT or service. Seller claims to accept the deal, or you reclaim your funds.

Example: Offer 2 ETH for a rare NFT

Crypto Gifts

Send birthday ETH to a friend. If they don't set up a wallet in time, reclaim it after the deadline.

Example: Gift 0.1 ETH for a birthday

Invoice Payments

Send an invoice link. Client deposits the payment, you claim upon delivering the service.

Example: Invoice for consulting services

Escrow Agreements

Lock funds for any conditional agreement. The recipient claims when conditions are met.
