  • blockbook: BE developed and deployed by SatoshiLabs. Provides access to Bitcoin(like) and Ethereum(like) networks.
  • ripple: third party BE that provides access to the Ripple network.
  • blockfrost: third party BE that provides access to the Cardano network.
  • electrum: protocol implemented by multiple third party backends that provide access to the Bitcoin network.

Usage

Add blockchain-link to your dependencies.

yarn add @trezor/blockchain-link

import BlockchainLink from '@trezor/blockchain-link';
import Blockbook from '@trezor/blockchain-link/lib/workers/blockbook';

const link = new BlockchainLink({
    name: 'Name used in logs.',
    worker: Blockbook,
    server: ['url1.of.the.be', 'url2.of.the.be'],
    debug: true,
});

try {
    const resp = link.getInfo();
} catch (error) {}
