Gateway-ts - library
This library provides a utility methods for helping decentralized Apps (dApps) to make use of on-chain identity methods like gateway token retrieval, lookup, and revocation.
Usage
Installation
yarn add @civic/solana-gateway-ts
Import
import {
addGatekeeper,
getGatekeeperAccountKeyFromGatekeeperAuthority,
getGatewayTokenKeyForOwner,
issue,
findGatewayTokens,
} from "@civic/solana-gateway-ts";
Functions
findGatewayTokens
Utility method for finding gateway token created for a given public key. This method does the lookup against the Solana blockchain. Returns an empty array if gateway tokens doesn't exist for the given public key.
const gatewayToken: PublicKey = await findGatewayToken(connection, owner, gatekeeperKey);
Optionally, a 'revoked' flag can be passed to allow retrieval of all, even revoked, tokens.
addGatekeeper
Creates the instruction for adding a gatekeeper to the gatekeeper network Usage:
const payer: Keypair;
const gatekeeperNetwork: Keypair;
const gatekeeperAccount: PublicKey;
const gatekeeperAuthority: PublicKey;
const transaction = new Transaction().add(
addGatekeeper(
payer.publicKey,
gatekeeperAccount,
gatekeeperAuthority,
gatekeeperNetwork.publicKey
)
);
await send(
connection,
transaction,
payer,
gatekeeperNetwork
);
getGatekeeperAccountKeyFromGatekeeperAuthority
Retrieves the gatekeeperAccount for a gatekeeper authority key, so the caller doens't need to keep a record of the gatekeeper account.
const gatekeeperAccount =
await getGatekeeperAccountKeyFromGatekeeperAuthority(
this.gatekeeperAuthority.publicKey
);
getGatewayTokenKeyForOwner
Derives a gateway token key for an owner using the gateway program, additionally accepting a seed parameter
const gatewayTokenKey = await getGatewayTokenKeyForOwner(owner);
issue
Issue a gatewayToken to an account
const owner: PublicKey;
const payer: Keypair;
const gatekeeperNetwork: Keypair;
const gatekeeperAccount: PublicKey;
const gatekeeperAuthority: PublicKey;
const gatewayTokenKey = await getGatewayTokenKeyForOwner(owner);
const gatekeeperAccount =
await getGatekeeperAccountKeyFromGatekeeperAuthority(
gatekeeperAuthority.publicKey
);
const transaction = new Transaction().add(
issue(
seed,
gatewayTokenKey,
payer.publicKey,
gatekeeperAccount,
owner,
gatekeeperAuthority.publicKey,
gatekeeperNetwork
)
);
await send(
connection,
transaction,
payer,
gatekeeperAuthority
);
findGatewayTokens
Find gatewayTokens that have been created on a network for an account
const owner: PublicKey;
const gatekeeperNetwork: Keypair;
const accounts = await findGatewayTokens(
connection,
owner.publicKey,
gatekeeperNetworkKey
);
