How It Works

A simple, secure process that protects both clients and contractors.

01

Create

Create an escrow contract between client and contractor.

The Client can create a contract, and invite The Developer to discuss it.

The Developer can create a contract and can invite The Client to discuss it.

02

Set Milestones

Define the milestones that must be completed.

The Client can set the milestones of the contract that The Developer must complete first to receive the funds.

The Developer can check the milestones of the contract that The Client set and can also add them.

03

Set Terms

Negotiate contract terms and deadline privately.

The Client can propose and edit the total payment amount and contract deadline.

The Developer can review and discuss the payment amount and deadline proposed by The Client.

04

Sign & Commit

Terms and deadline are committed to L1.

The Client signs the agreed terms, locking the contract for funding.

The Developer signs the agreed terms, confirming the payment and deadline.

05

Fund

Funds stay locked until completion.

The Client funds the escrow with the total payment amount.

The Developer waits for The Client to fund the escrow before starting work.

06

Complete Milestones

Contractor submits, client approves.

The Client reviews and approves each milestone as The Developer completes them.

The Developer submits milestones for The Client approval. No payout occurs until all are approved.

07

Payout!

Contractor claims payout.

The Client already paid at funding, but funds are only released after all tasks are completed and approved. If The Developer misses the deadline, The Client can reclaim the funds.

After all milestones are approved, The Developer claims the final payout in one transfer.

Client Safety

Funds only move when milestones are approved. No partial payouts until all work is complete.

Contractor Safety

Funds are locked upfront in the escrow PDA. Payment is secured on-chain before work starts.

Privacy

Terms and milestones are stored in MagicBlock PER. Only authorized parties can read them.

Dispute Resolution

On-chain judge resolves disputes according to program rules before final approval.

Timeout Protection

Clients can claim refunds if deadlines expire. Mutual cancel option available.

Non-Custodial

Funds are held by the escrow program (PDA), not a company. No third-party risk.
