Release Notes

api3dao/chains (@​api3/chains)

v4.1.0

Compare Source

New Features

Optional Viem config environment variable support

viemConfig.chains() now (optionally) supports adding additional rpcUrls values using specific environment variables. These environment variables take the form of API3_CHAINS_HTTP_RPC_URL_${toUpperSnakeCase(chain.alias)}. When a matching value is detected, a new environment key is added to rpcUrls.

NOTE: you can still access the existing provided default and public values, as these are not affected.

For example, the new rpcUrls object will look like:

{
  default: { http: ['https://existing-rpc.xyz'] },
  public: { http: ['https://existing-rpc.xyz'] },
+ environment: { http: ['https://custom-rpc.xyz'] },
}

v4.0.0

Breaking changes

providerUrl is now a providers array

providerUrl has been replaced with a providers array to allow for more than 1 RPC provider. Each provider object has the following interface:

interface ChainProvider {
  alias: string;
  homepageUrl?: string;
  rpcUrl?: string;
}

NOTE:

• Each chain MUST have at least one provider with an alias of default
• rpcUrl is optional to allow for values that may contain a sensitive API key in the URL

You can migrate existing providerUrl code with the following snippet

- chain.providerUrl
+ chain.providers.find((p) => p.alias === 'default')!.rpcUrl!;

New Features

Viem Config support

You can now generate chains compatible with Viem/Wagmi

import { viemConfig } from '@​api3/chains';
console.log(viemConfig.chains());
/*
[
  {
    id: 421613,
    name: 'arbitrum-goerli-testnet',
    network: 'arbitrum-goerli-testnet',
    nativeCurrency: { ... },
    rpcUrls: { default: ..., public: ... }
    blockExplorers: { default: ..., public: ... }
    ...
  },
  ...
]
*/

Updated Chains

In all cases, the alias value is unchanged

1. RSK renamed to Rootstock and has a new default RPC URL
2. RSK Testnet renamed to Rootstock Testnet and has a new default RPC URL
3. Arbitrum renamed to Arbitrum One
4. BSC renamed to BNB Smart Chain
5. BSC Testnet renamed to BNB Smart Chain Testnet

Miscellaneous

zkSync hardhat config overrides

zkSync (and zkSync Testnet) require additional fields for use with Hardhat. These fields are now included with the respective chain definitions and used when generating the Hardhat config.

See issue: https://github.com/api3dao/chains/issues/55 and the chain definitions for more information
