Centrifuge JavaScript SDK

CentrifugeSDK provides a JavaScript client to interact with the Centrifuge ecosystem. It provides a comprehensive interface to easily create and manage pools, nfts, loans and metadata.

Installation

CentrifugeSDK uses Viem under the hood. It's necessary to install it alongside the SDK.

npm install --save @centrifuge/centrifuge-sdk viem

Init and config

Create an instance and pass optional configuration

import Centrifuge from '@centrifuge/centrifuge-sdk'

const centrifuge = new Centrifuge()

The following config options can be passed on initilization of CentrifugeSDK:

• environment: 'mainnet' | 'demo' | 'dev'
  • Optional
  • Default value: mainnet
• rpcUrls: Record<number, string>
  • Optional
  • A object mapping chain ids to RPC URLs

Queries

Queries return Promise-like Observables. They can be either awaited to get a single value, or subscribed to to get fresh data whenever on-chain data changes.

try {
  const pool = await centrifuge.pools()
} catch (error) {
  console.error(error)
}

const subscription = centrifuge.pools().subscribe(
  (pool) => console.log(pool),
  (error) => console.error(error)
)
subscription.unsubscribe()

The returned results are either immutable values, or entities that can be further queried.

Transactions

To perform transactions, you need to set a signer on the centrifuge instance.

centrifuge.setSigner(signer)

signer can be a EIP1193-compatible provider or a Viem LocalAccount

With this you can call transaction methods. Similar to queries they can be awaited to get their final result, or subscribed to get get status updates.

const pool = await centrifuge.pool('1')
try {
  const status = await pool.closeEpoch()
  console.log(status)
} catch (error) {
  console.error(error)
}

const pool = await centrifuge.pool('1')
const subscription = pool.closeEpoch().subscribe(
  (status) => console.log(pool),
  (error) => console.error(error),
  () => console.log('complete')
)
