Credenza EVM Provider\n\nA standalone EVM provider implementation for Credenza3 authentication that implements the EIP-1193 standard.\n\n## Installation\n\n```\n npm i @credenza3/core-web-evm-provider-ext\n```\n\n## Overview\n\n`CredenzaProvider` is a custodial EVM provider that uses Credenza3's backend for key management and transaction signing. It implements the standard `Eip1193Provider` interface, making it compatible with ethers.js and other Web3 libraries.\n\n## Usage\n\n### Basic Setup\n\n```\nimport CredenzaProvider from '@credenza3/core-web-evm-provider-ext'\n\n\nconst provider = new CredenzaProvider({\n rpcUrl: '',\n accessToken: 'your-credenza-access-token',\n env: 'staging', // 'prod' | 'staging'\n})\n```\n\n### Using with ethers.js\n\n```\nimport { BrowserProvider } from 'ethers'\n\nconst ethersProvider = new BrowserProvider(provider)\nconst signer = await ethersProvider.getSigner()\n\nconst address = await signer.getAddress()\n\nconst tx = await signer.sendTransaction({\n to: '0x...',\n value: ethers.parseEther('0.1'),\n})\n```\n\n## API Reference\n\n### Constructor\n\n```\n new CredenzaProvider(params: {\n rpcUrl: string\n accessToken?: string\n env: string\n })\n```\n\n**Parameters:**\n\n- `rpcUrl` - RPC URL of the blockchain network\n- `accessToken` - Credenza3 authentication token\n- `env` - Environment ('prod' | 'staging')\n\n### Methods\n\n#### `setAccessToken(accessToken: string)`\n\nUpdates the access token.\n\n```\nprovider.setAccessToken('new-access-token')\n```\n\n#### `setRpcUrl(rpcUrl: string): Promise`\n\nSwitches to a different blockchain network.\n\n```\nawait provider.setRpcUrl('https://eth.llamarpc.com')\n```\n\n#### `getRpcUrl(): string`\n\nReturns the current RPC URL.\n\n```\nconst rpcUrl = provider.getRpcUrl()\n```\n\n#### `listAccounts(): Promise`\n\nReturns the list of accounts.\n\n```\nconst accounts = await provider.listAccounts()\n```\n\n#### `getRpcProvider(): Promise`\n\nReturns the underlying ethers JsonRpcProvider.\n\n```\nconst rpcProvider = await provider.getRpcProvider()\n```\n\n#### `request(args: { method: string; params?: unknown[] }): Promise`\n\nImplements EIP-1193 request method.\n\n```\nconst accounts = await provider.request({ method: 'eth_accounts' })\n\nconst signature = await provider.request({\n method: 'personal_sign',\n params: [message, address],\n})\n\nconst txHash = await provider.request({\n method: 'eth_sendTransaction',\n params: [{ to: '0x...', value: '0x...' }],\n})\n```\n\n### Supported RPC Methods\n\n**Account Methods:**\n\n- `eth_requestAccounts` / `eth_accounts`\n- `personal_sign` / `eth_sign`\n- `eth_signTypedData` / `eth_signTypedData_v4`\n\n**Transaction Methods:**\n\n- `eth_signTransaction`\n- `eth_sendTransaction` / `eth_sendRawTransaction`\n\n**Standard Methods:**\nAll other standard Ethereum JSON-RPC methods are forwarded to the RPC provider.\n\n## Example\n\n```\nimport { CredenzaProvider } from '@packages/evm-provider'\nimport { BrowserProvider, parseEther } from 'ethers'\n\nconst provider = new CredenzaProvider({\n rpcUrl: 'https://eth.llamarpc.com',\n accessToken: 'your-token',\n env: 'prod',\n})\n\nconst accounts = await provider.listAccounts()\n\nconst ethersProvider = new BrowserProvider(provider)\nconst signer = await ethersProvider.getSigner()\n\nconst tx = await signer.sendTransaction({\n to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb',\n value: parseEther('0.01'),\n})\n\nawait tx.wait()\n```\n","readmeFilename":"README.md"}
