Free Smart Contract Developer
Service Agreement
One bug in your code is a hole in the hull that sinks the whole ship and leaves you drowning in multi-million dollar lawsuits. Without a signed paper trail, you're the sacrificial lamb when the treasury gets drained and the investors start looking for someone to sue.
Pro Contractor Tip
Include a 'Limitation of Liability' clause to cap your financial exposure at the total project fee, otherwise you're betting your house on every line of Solidity you write.
Why use a written agreement?
Handshake deals are risky. As a Smart Contract Developer, "scope creep" is your biggest enemy. A clear agreement ensures everyone agrees on the deliverables before money changes hands.

Frequently Asked Questions
The client keeps asking for extra functions after we started. How do I stop the bleeding?
That's scope creep, plain and simple. Use your 'Change Order' clause to show them the original blueprint and inform them that new features require a signed amendment and an additional deposit before you touch the keyboard.
How do I make sure I actually get paid once the code is on the mainnet?
Never hand over the final deployment keys or verify the source until the final wire clears. Your contract should explicitly state that intellectual property only transfers from your hands to theirs once the balance is zeroed out.
What happens if the protocol gets exploited six months from now?
You need an 'Acceptance of Work' clause. Once the client signs off on the final audit and takes delivery, the clock starts on a limited warranty period, making it clear that you aren't an unpaid insurance policy for their future mistakes.
