Atlas Config - TypeScript

TypeScript package that provides chain configurations for Atlas Protocol smart contracts. This package is part of the Atlas Protocol suite and is designed to work seamlessly with the Atlas SDK.

Installation

npm install @fastlane-labs/atlas-config
# or
pnpm add @fastlane-labs/atlas-config
# or
yarn add @fastlane-labs/atlas-config

Usage

Basic Usage

import { getChainConfig } from '@fastlane-labs/atlas-config';

// Get config for a specific chain
const sepoliaConfig = getChainConfig(11155111); // Sepolia testnet
console.log(sepoliaConfig.contracts.atlas); // Atlas contract address
console.log(sepoliaConfig.eip712Domain); // EIP-712 domain config

Getting Supported Chain IDs

import { getSupportedChainIds } from '@fastlane-labs/atlas-config';

const chainIds = getSupportedChainIds();
console.log("Supported chain IDs:", chainIds); // [137, 11155111, ...]

Getting All Chain Configs

import { getAllChainConfigs } from '@fastlane-labs/atlas-config';

const allConfigs = getAllChainConfigs();
console.log("All chain configs:", allConfigs.map(config => ({
  chainId: config.chainId,
  name: config.config.eip712Domain.name
})));

Merging Custom Configurations

You can merge your own configurations with the default ones. This is useful for testing or using custom contract deployments.

import { mergeChainConfigs } from '@fastlane-labs/atlas-config';

// Example: Updating a single contract address
const partialUpdate = {
  '11155111': { // Sepolia
    '1.0': {
      contracts: {
        atlas: { address: '0x1234567890123456789012345678901234567890' }
      }
    }
  }
};

// Example: Adding a new chain with complete configuration
const newChainConfig = {
  '999999': {
    '1.0': {
      contracts: {
        atlas: { address: '0x0987654321098765432109876543210987654321' },
        atlasVerification: { address: '0x0987654321098765432109876543210987654321' },
        sorter: { address: '0x0987654321098765432109876543210987654321' },
        simulator: { address: '0x0987654321098765432109876543210987654321' },
        multicall3: { address: '0x0987654321098765432109876543210987654321' }
      },
      eip712Domain: {
        name: 'New Test Chain',
        version: '1.0',
        chainId: 999999,
        verifyingContract: '0x1111111111111111111111111111111111111111'
      }
    }
  }
};

// Merge configurations
try {
  const mergedConfigs = mergeChainConfigs({
    ...partialUpdate,
    ...newChainConfig
  });
  console.log("Updated Sepolia config:", mergedConfigs['11155111']);
  console.log("New chain config:", mergedConfigs['999999']);
} catch (error) {
  console.error("Error merging configs:", error);
}

Integration with Atlas SDK

The package is designed to work seamlessly with the Atlas SDK:

import { getChainConfig } from '@fastlane-labs/atlas-config';
import { OperationBuilder } from '@fastlane-labs/atlas-sdk';

// Example: Creating a solver operation
OperationBuilder.newSolverOperation({
  from: "0x...",
  to: "0x...",
  value: BigInt(0),
  gas: BigInt(0),
  maxFeePerGas: BigInt(0),
  deadline: BigInt(0),
  solver: "0x...",
  control: "0x...",
  userOpHash: "0x...",
  bidToken: "0x...",
  bidAmount: BigInt(10000000000000000), // 0.01 ETH
  data: "0x...",
  signature: "0x..."
});

Configuration Types

Contract Configuration

type ContractConfig = {
  atlas: string;
  atlasVerification: string;
  sorter: string;
  simulator: string;
  multicall3: string;
};

EIP-712 Domain Configuration

type EIP712Domain = {
  name: string;
  version: string;
  chainId: number;
  verifyingContract: string;
};

Version Configuration

type VersionConfig = {
  contracts: ContractConfig;
  eip712Domain: EIP712Domain;
};

Error Handling

The package includes proper error handling for common scenarios:

// Invalid chain ID
try {
  const config = getChainConfig(999999);
} catch (error) {
  console.error("Chain not supported:", error);
}

// Invalid version
try {
  const config = getChainConfig(11155111, '9.9');
} catch (error) {
  console.error("Version not found:", error);
}

// Incomplete configuration when merging
try {
  const incompleteConfig = {
    '888888': {
      '1.0': {
        contracts: {
          atlas: { address: '0x1234567890123456789012345678901234567890' }
        }
      }
    }
  };
  mergeChainConfigs(incompleteConfig);
} catch (error) {
  console.error("Expected error:", error);
}
