Providers

In this section, Xchain UTXO Providers and Xchain EVM Providers are described in detail.

Xchain UTXO Providers

The xchain-utxo-providers likely refers to providers or sources of UTXO (Unspent Transaction Output) data that can be utilized within the xchain-utxo module for various purposes such as wallet management, transaction broadcasting, and UTXO manipulation. These providers may offer APIs or services for querying UTXO data from different blockchain networks. Here are the list of some possible providers:

1. Blockchain Explorers:

   • Blockchain explorers are web-based tools or APIs that allow users to inspect and query data from blockchain networks. These explorers typically provide information about transactions, blocks, addresses, and UTXOs. Examples of blockchain explorers for UTXO-based chains include:

     • Blockchair

     • Blockstream.info

     • Bitpay's Insight API

2. Node APIs:

   • Full nodes running on blockchain networks often expose APIs that allow developers to interact with the network programmatically. These APIs may include methods for querying UTXO data, retrieving transaction information, and broadcasting transactions. Examples of node APIs for UTXO-based chains include:

     • Bitcoin Core RPC API

     • Litecoin Core RPC API

     • Dash Core RPC API

3. Third-Party Services:

   • Some third-party services specialize in providing blockchain data and infrastructure services to developers. These services may offer APIs for accessing UTXO data from multiple blockchain networks, along with additional features such as analytics, monitoring, and wallet management. Examples of third-party services for UTXO-based chains include:

     • Blockcypher

     • Chain.so

     • BitGo

4. Custom Nodes:

   • Developers or organizations may run custom nodes on UTXO-based blockchain networks to support their applications or services. These custom nodes can be configured to expose APIs for querying UTXO data and performing other blockchain-related operations. Examples of custom nodes include:

     • Self-hosted Bitcoin, Litecoin, or Dash nodes

     • Nodes hosted on cloud providers such as AWS, Azure, or Google Cloud

5. Decentralized Infrastructure:

   • Some blockchain networks rely on decentralized infrastructure for data availability and query capabilities. Providers of decentralized infrastructure may offer APIs or protocols for accessing UTXO data from these networks in a trustless and decentralized manner. Examples of decentralized infrastructure providers include:

     • InterPlanetary File System (IPFS)

     • Ethereum Name Service (ENS)

     • Skynet

Xchain EVM Providers

The "xchain-evm-providers" likely refers to providers or interfaces that allow interaction with various Ethereum Virtual Machine (EVM) compatible blockchains.

These providers facilitate communication with the respective blockchain networks, enabling developers to build decentralized applications (DApps), deploy smart contracts, and perform transactions. Below, is the list and description of some common providers that may fall under this category:

1. Alchemy:

   • Alchemy is a blockchain infrastructure provider that offers APIs and developer tools for building applications on various EVM-compatible blockchains. It provides reliable access to Ethereum nodes, allowing developers to interact with the Ethereum network seamlessly.

2. Infura:

   • Infura is a popular Ethereum infrastructure provider that offers APIs for accessing Ethereum nodes. It provides scalable and reliable access to Ethereum's infrastructure, enabling developers to build and deploy decentralized applications without running their own Ethereum nodes.

3. Etherscan:

   • Etherscan is a block explorer and analytics platform for Ethereum and EVM-compatible blockchains. While primarily known for its block explorer functionality, Etherscan also offers APIs that allow developers to interact with the Ethereum network, access blockchain data, and perform transactions.

4. QuickNode:

   • QuickNode provides infrastructure services for blockchain networks, including Ethereum and EVM-compatible chains. It offers fully-managed nodes, APIs, and developer tools for building applications on these networks, providing developers with reliable access to blockchain data and functionality.

5. Chainstack:

   • Chainstack is a blockchain infrastructure platform that offers managed node services for Ethereum and other EVM-compatible blockchains. It provides developers with tools to deploy and manage blockchain nodes easily, enabling them to focus on building decentralized applications without worrying about node infrastructure.

6. QuikNode:

   • QuikNode is another provider of Ethereum infrastructure services, offering fully-managed nodes, APIs, and developer tools for building applications on Ethereum and EVM-compatible chains. It provides scalable and reliable access to blockchain data and functionality.

7. Ankr:

   • Ankr is a distributed computing platform that offers infrastructure services for blockchain networks, including Ethereum and EVM-compatible chains. It provides developers with access to blockchain nodes, APIs, and developer tools, enabling them to build and deploy decentralized applications.

8. Pocket Network:

   • Pocket Network is a decentralized infrastructure protocol that provides access to blockchain networks through a network of independent node operators. It offers APIs and developer tools for building applications on Ethereum and other EVM-compatible chains, leveraging decentralized infrastructure for reliability and scalability.
