Learn how to compare a local file of your contract, signature or template to the one in the blockchain.

Before signing a contract, or even when you receive a contract, you might want to verify the authenticity of the contract. With the power of blockchain, you can compare if the contract you are about to sign is the one that was given to you. You can also compare the authenticity of a template, or even the signatures of a signed contract. The comparison is done by comparing their fingerprints.

Here's a list of comparisons you can do:

  • Compare a contract to a contract on the blockchain
  • Compare a signature to all the signatures of a contract on the blockchain
  • Compare a signature to a signature on the blockchain
  • Compare a template to a template on the blockchain

Compare a contract to a contract on the blockchain

Compare a local contract file to a contract that is stored on the blockchain, by performing a standard POST call with your API key in the header. Your API key must be valid for this to work. If you don't have an API key, follow this short tutorial to get one.

🚧

Permissions

Requires Sealer Admin Role if you want to compare to any contract on the blockchain.
Requires Sealer User Role if you only want to compare your own contracts.

Let's try it out!

curl -X POST \
  'http://api.mantleblockchain.com/sealer/{{PRODUCT_ID}}/contracts/{{CONTRACT_ID}}/compare/contract' \
  -H 'Accept: text/plain, application/json, text/json' \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: multipart/form-data' \
  -H 'x-api-key: {{API_KEY}}' \
  -F 'file={{CONTRACT_FILE}}'

Replace the following parameters:

{{PRODUCT_ID}}: Your Product id
{{CONTRACT_ID}}: The ID of the contract which you want to compare
{{API_KEY}}: Your own API key
{{CONTRACT_FILE}}: The contract file you want to use for the comparison
