Signing is
paying.

DealSeal collapses the contract and the deposit into a single cryptographic act. One signature commits the document and moves the money into escrow — atomic, on Avalanche.

§ 00 / Trust

Know you're being paid
before you start the work.

The deposit isn't a promise. It's already in escrow when the contract is signed — verifiable, on-chain, before line one of your invoice exists.

The question · 01
“Will they actually pay?”
They already have.
The signature and the deposit are one transaction. If the deposit fails, the signature reverts. There is no signed contract with an unpaid deposit — by construction.

The question · 02
“How do I know the funds are real?”
You can read the chain.
Click the deposit on any contract page and you land on the live escrow address — the dNZD balance, the deposit tx, the block number. Public. Yours to verify.

The question · 03
“Can they pull the deposit back?”
No. Only mutual approval releases.
The escrow has no admin key, no upgrade path, no withdraw path. Once the deposit lands, it moves only when both wallets approve — to you. Or, in dispute, nowhere at all.

§ 01 / Premise
Today, a contract and its deposit are two forms, two systems, and two legal risks. “I signed but never paid.” “I paid but never received the doc.” DealSeal removes both, by removing the gap between them.
§ 02 / Flow

Three steps. One commitment.

01Step
Upload & sign first
You upload the PDF, sign it, and set the deposit amount in NZD. The PDF is content-addressed to IPFS; its hash is committed on-chain.
02Step
Send the share link
Your counterparty receives a link with the secret in the URL fragment — never logged, never indexable. They review the document before any wallet prompts.
03Step
They sign + pay, atomic
One transaction binds their signature and moves dNZD into the per-deal escrow. Funds release only when both of you approve.
§ 03 / State

The whole protocol fits on a single line.

Each escrow is a per-deal contract clone — immutable, no admin key, no upgrade path. The state machine below is the entire surface.

Carry your record
across borders.

Every completed contract accrues to your wallet — visible counts and dispute rate, never raw dollar amounts or counterparty names. An NZ contractor's track record travels with them.
