Developing on Mantle
Mantle v2 Tectonic has been released, please move to the new documentation!
Check out our repository of Mantle-specific tutorials on the Mantle GitHub!

The official Mantle RPC employs rate limiting to ensure stability during traffic spikes. If your particular use case involves calling the Mantle API frequently, you might run into issues that arise due to rate limiting. For such use cases, consider connecting to third-party RPCs instead. You can find the list of available RPC providers here: Node RPC Providers
Contract Addresses
The most updated list of addresses of the contracts deployed on Ethereum and Mantle Network are available on Github. Follow the links below to navigate to the respective address repos.
Please note that there are some common ERC20 contract operations currently inactive for the native $MNT token, namely:
transfer()approve()transferFrom()increaseAllowance()decreaseAllowance()
If your dApps use any of the above operations, we recommend using the wrapped token $WMNT instead. The L2 Mainnet contract address for $WMNT is 0x78c1b0c915c4faa5fffa6cabf0219da63d7f4cb8
Connecting to Mantle Testnet
Use the info listed in the Network Details table above to connect your wallets and apps to Mantle testnet.

GitHub
Our GitHub is a good place to familiarize yourself with the Mantle tech stack and find tools and usage examples for reference that'll help you set up a local development environment, integrate our SDK, invoke node RPC endpoints, and more.

Mantle SDK
You can learn more about the Mantle SDK in Mantle Client SDK. The SDK provides support for the following:
Inter-network message-passing
Token deposit and withdrawal between Layer 1 (L1) and Layer 2 (L2) networks
Creation of ERC-20 tokens on L2 mapping to L1 token
Monitoring of contract calls, emit messages, etc.
By combining SDK modules, Mantle network can be easily connected to wallets, exchanges, and other application scenarios. Use the link below to navigate to our SDK docs.
Thirdweb SDK
The thirdweb web3 development framework supports deploying apps to Mantle Network. Learn more about how to use the thirdweb CLI to deploy contracts, and the thirdweb SDK to build your applications connecting to Mantle Network on the Thirdweb SDK page.
Using Mantle Node API
dApps need access to nodes to fetch block data and send transactions. Mantle network supports Ethereum's JSON-RPC API implementation with some added custom methods and can be connected to using HTTPS and WebSocket. Find out more on the Mantle Node API page.
