How it works
Post a Job
Describe what you need, set your budget in BNB, and define milestones. Your job goes live instantly for freelancers to discover.
Review & Hire
Receive proposals from skilled freelancers, review their profiles and portfolios, chat to align on requirements, and hire the right fit.
Pay Securely via Escrow
Fund milestones through on-chain escrow. Funds are held safely in a smart contract and only released when you approve the delivered work.
Real transactions. Real transparency.
Every escrow fund, delivery, approval, and withdrawal on Grumbuild is a real transaction on BNB Smart Chain - publicly verifiable by anyone, anytime.
Escrow Funding Transaction
When a client funds a milestone, BNB is sent directly to the escrow smart contract. This transaction is recorded on BSC and visible on BscScan - proving the funds are locked and protected.
Freelancer Withdrawal Transaction
Once work is approved, the freelancer withdraws their payout directly from the escrow contract. The transaction shows the exact BNB amount, platform fee split, and GRMPS reward distribution.
Escrow Smart Contract on BscScan
Each milestone deploys its own escrow contract via the EscrowFactory using gas-efficient minimal proxies. Every contract is publicly accessible on BscScan - you can inspect the code, verify transactions, and confirm that funds are handled exactly as the rules define.
Why Grumbuild?
Traditional platforms hold your money and charge high fees. Grumbuild puts you in control with blockchain-powered escrow.
On-Chain Escrow
Every milestone gets its own smart contract. Funds are locked until work is approved - no one can touch them, not even us.
Low Fees, Fair Split
Just ~1% total platform fee, split between client and freelancer. The smart contract handles routing automatically at payout.
Direct Wallet Payments
No waiting for bank transfers. Freelancers withdraw directly from escrow to their wallet the moment work is approved.
Milestone Workflow
Break projects into clear milestones with defined deliverables. Fund, deliver, approve, and pay - step by step.
Fair Dispute Resolution
Disagreements are handled on-chain with an independent arbiter. Fee-based disputes discourage bad actors and resolve quickly.
GRMPS Rewards
Complete projects without disputes and earn GRMPS token rewards. Good collaboration is rewarded for both clients and freelancers.
