Devnet Configuration

The Synapse SDK supports local development networks in addition to mainnet and calibration.

Network Support

Network	Chain ID	Auto-Discovery
mainnet	314	Yes
calibration	314159	Yes
devnet	31415926	No

For mainnet and calibration, contract addresses are auto-discovered. For devnet, you must provide addresses explicitly.

Required Options

When connecting to a devnet, provide these options:

import { Synapse } from '@filoz/synapse-sdk'

const synapse = await Synapse.create({
  privateKey: process.env.PRIVATE_KEY,
  rpcURL: process.env.RPC_URL,
  warmStorageAddress: process.env.WARM_STORAGE_ADDRESS,
  multicall3Address: process.env.MULTICALL3_ADDRESS,
  // Optional: override USDFC token address
  usdfcAddress: process.env.USDFC_ADDRESS,
})

All other contract addresses (Payments, PDPVerifier, ServiceProviderRegistry, SessionKeyRegistry) are discovered automatically from warmStorageAddress.

Local Development

For local development and integration testing, see foc-localnet which provides a complete local Filecoin network with all FOC contracts deployed.
