Budget: 27000 UAH Deadline: 3 days
Hello, Alex
I will collect the code today, I need the budget for deploying the contract and IPFS.
Write to me, it needs to be done.

Good day.
I can implement such a contract without any problems. The essence of the task is completely clear to me, very simple, and I have more than enough skills to execute it in the best way. I have worked with IPFS, hash functions, and developed smart contracts in Solidity for EVM blockchains. Writing a clear instruction in "simple language" without unnecessary complications will also not be a problem for me.
It is indeed an easy task that I will quickly complete for you. I will be happy to help you and answer any technical questions that may arise.

✋ Hello! We are the IT company dZENcode.
We implement on-chain PDF fixation: a contract on the Ethereum mainnet with a SHA-256 hash, IPFS CID, and the name of the association, IPFS integration, and Etherscan verification, based on the team's experience, best practices, and our own developments.
Is the final signed PDF ready for hashing?
Shall we deploy the contract from your wallet or our account?
You can find detailed information about our services and rates on our website: 
Freelancehunt.
Take a look – we will discuss the details of the work further, write when you are ready.
The final cost is formed only after clarifying the volume and requirements.

International association without jurisdiction — the document must be recorded in such a way that anyone can verify its existence independently of any intermediary. This is precisely why proof-of-existence exists on Ethereum.
I will create a minimal Solidity contract: SHA-256 hash of the PDF, IPFS CID, blockchain timestamp. I will upload the PDF to IPFS, deploy the contract on the mainnet, and verify it on Etherscan — the code is open and verifiable. The output will be: contract address, tx hash, CID, and instructions for independent verification without trust in me.
No tokens or unnecessary complexity — just an immutable record of the fact.

Ready to implement proof-of-existence:
SHA-256 hash, IPFS, minimal contract in Ethereum (hash, CID, timestamp), deployment and verification.

Good day
Please clarify whether you need this done as a one-time task or to create a web application that will allow for the automatic execution of all these actions in the future.
Otherwise, the technical specifications are quite simple, I am ready to implement all of the above. Experience working with blockchain - 8 years, I constantly write smart contracts for EVM networks.
