Trusted Hint Registry
This repository contains a smart contract for a registry of trusted hints used in decentralized ecosystems based on ERC-7506. It provides a standardized on-chain metadata management system aiding in verification of on- and off-chain data, like Verifiable Credentials.
Key Decisions
- Upgradable smart contract using ERC1967 to enable future feature additions and bug fixes.
- General purpose, access-controlled data structure usable by any address for hints.
- Development, testing, and deployment is done via the Foundry toolset.
- The deployments and ABI are provided via an NPM package from this repository.
Usage
Build
forge build
Test
forge test
Deploy
forge script DeployProxy --rpc-url <your_rpc_url> --private-key <your_private_key> --etherscan-api-key <your_etherscan_key> --verify --optimize --broadcast
Usage in other projects
Install
npm i @spherity/trusted-hint-registry
Import
This package provides separate build for CommonJS and ES modules. You can import it in your project like this:
import { TRUSTED_HINT_REGISTRY_ABI, deployments } from "@spherity/trusted-hint-registry"
In combination with, e.g., viem, you can use it like this:
import { TRUSTED_HINT_REGISTRY_ABI, deployments } from "@spherity/trusted-hint-registry";
import { getContract } from 'viem'
const publicClient = createPublicClient({
chain: sepolia,
transport: http(),
})
const sepoliaDeployment = deployments.find(d => d.chainId === 11155111 && d.type === "proxy")
const contract = getContract({
address: sepoliaDeployment.registry,
abi: TRUSTED_HINT_REGISTRY_ABI,
publicClient,
})
const namespace = "0x..."
const list = "0x..."
const key = "0x..."
const hint = await contract.read.getHint(namespace, list, key)
)
