Chains

In chains.ts the different Aptos and Aptos-based chains are defined and exported as defaultChains.

export type Chain = {
  id: string;
  name: string;
  network: Network;
  fullnode?: string;
  indexer?: string;
  faucet?: string;
  block_explorer?: string;
};

The default Aptos chains only require the mandatory fields (id, name, and network). However, for custom chains, it's recommended to provide all fields to ensure a fully functional dapp.

warning

The Aptos devnet is frequently reset, which can result in changes to the chainId. If this occurs, you should:

Redeploy your modules (this process always uses the correct chainId)
Manually update the chainId for devnet in packages/nextjs/utils/scaffold-move/chains.ts
