Sample Hardhat Project

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.

Try running some of the following tasks:

npx hardhat help
npx hardhat test
REPORT_GAS=true npx hardhat test
npx hardhat node

Contracts

TrustSigil

Logic

• represents a trust relationship between minter and recipient of a non-transferable ERC1155 token (aka the sigil)
• specifically the token expresses that the person who minted the token to the recipient trusts the recipient, or phrased differently that the recipient is being trusted by the minter
• the context of the trust relationship is represented by the tokenId of the sigil (and the metadata that can be attached to the tokenId)
• in addition to the ERC1155 functionalities (with transfers being disabled), the contract stores for each user A, per tokenId, if user A has received a trust sigil from user B by recording the blocknumber when minting took place (variable name: sigils)
• before a sigil with a specific tokenId can be minted it needs to be set up first (setupSigil) (can be done by anyone):
  • when setting up the sigil the the user needs to specified whether a TrustAttestor should be used for that sigil or not
  • the TrustAttestor is a contract that could implement arbitrary logic to attest to the trust relationship between user A and user B
  • in the context of the hackathon, the TrustAttestor would be a contract that checks if there is a follower-relationship between user A and user B
  • if no TrustAttestor should be used for the tokenId, the user setting up the sigil needs to pass 0x1111111111111111111111111111111111111111 as address

Testing locally

• install dependencies: npm i
• have a local node running in a separate terminal window: npx hardhat node
• run npx hardhat --network localhost setup:testing
  • this will deploy a TrustSigil contract and an OrbisBridge contract tied to the pkp 0xC5c8D3533cD0eB838c60AEeea5dF6fE23E34b67C
  • it will also invoke setupSigil with tokenId = 1 and the address of the OrbisBridge as trustAttestor
