On chain

import {SolidusGate} from "./SolidusGate.sol"; // github.com/solidusnetwork/bridge-contracts, src/lib/SolidusGate.sol

// Reverts with the REASON, not just a refusal, so you can tell the holder what to fix.
SolidusGate.requireCredential(
    mirror,                       // SolidusRegistry.mirrorOf(domain)
    SolidusGate.holderOf(msg.sender),
    keccak256("KycL2"),
    issuerDidHash,
    1 days                        // how stale a heartbeat may be
);

In a frontend

import { checkGate, credentialTypeHash, gateReasonName, holderFromEvmAddress } from '@solidus-network/bridge'

const result = await checkGate({
  client: publicClient,
  mirror: mirrorAddress,
  holder: holderFromEvmAddress(account.address),
  credentialTypeHash: credentialTypeHash('KycL2'),
  issuerDidHash,
  maxAge: 86_400n,
})

if (!result.ok) show(`cannot proceed: ${gateReasonName(result.reason)}`)

You supply the client. This package ships no RPC URL of its own.
