Frontier & Polkadot Integration

Splendor V3 (Tokio) is designed to offer the best of both worlds: full Ethereum compatibility and the flexibility of the Polkadot/Substrate ecosystem. This page explains how we achieve this using Frontier and how Splendor can connect with the broader Polkadot network.

What is Frontier?

Frontier is a set of tools and modules that brings Ethereum compatibility to Substrate-based blockchains like Splendor. With Frontier, Splendor can:

Run Ethereum smart contracts (Solidity, Vyper, etc.)
Support Ethereum wallets (like MetaMask)
Use Ethereum developer tools (Hardhat, Truffle, Foundry)
Provide Ethereum-style RPC endpoints (so dApps and wallets work out of the box)

In short: Frontier makes Splendor look and feel like Ethereum to users and developers, while running on a modern, flexible Substrate core.

How Splendor Uses Frontier

EVM Support: Splendor runs an Ethereum Virtual Machine (EVM) inside its blockchain, so you can deploy and interact with Ethereum smart contracts.
Ethereum RPC: You can connect to Splendor using the same tools you’d use for Ethereum (like ethers.js, web3.js, MetaMask, etc.).
Low Fees, Fast Blocks: Enjoy Ethereum compatibility with much lower fees and faster block times (2 seconds).
Precompiles: Splendor includes special precompiled contracts for cryptographic operations, just like Ethereum.

What is Polkadot?

Polkadot is a network of blockchains (called parachains) that can communicate and share security. It’s built using Substrate, just like Splendor.

Interoperability: Polkadot allows different blockchains to talk to each other and transfer assets or data.
Shared Security: Parachains benefit from the security of the Polkadot Relay Chain.
Cross-Chain Apps: Developers can build apps that use features from multiple blockchains at once.

Splendor & Polkadot: How They Can Work Together

Splendor is currently an independent chain, but thanks to Substrate, it’s designed for future cross-chain capabilities:

Bridges: In the future, Splendor can connect to Polkadot or other blockchains using bridges. This will allow token transfers and data sharing between Splendor and other networks.
XCMP (Cross-Chain Message Passing): Substrate’s technology allows blockchains to send messages to each other. Splendor can adopt this to interact with Polkadot or other Substrate chains.
Polkadot.js Integration: You can already use Polkadot.js Apps to interact with Splendor nodes for advanced features.

Why Does This Matter?

For Developers: You can build Ethereum-style dApps on Splendor, but also tap into the power of Substrate and Polkadot for cross-chain features.
For Users: Enjoy fast, low-cost transactions and the ability to use familiar Ethereum wallets and tools.
For the Future: As bridges and cross-chain features mature, Splendor will be able to connect with the wider Polkadot ecosystem and beyond.
