PAXEER / DEVELOPER DOCUMENTATION
Build what’s next.
Start with Paxeer.
The guides, interfaces and building blocks for your next application.
From your first request to the infrastructure underneath.
125Native token PAXFamiliar tools. New possibilities.
Work with EVM contracts, JSON-RPC and the Ethereum tools you already know.
Your node. Your view of the chain.
Build paxd, configure your environment and learn to operate a node.
Every layer. In the open.
Explore execution, consensus, storage and the modules connecting them.
01 / THE FOUNDATION
One network. A place to build.
Paxeer brings EVM execution and Cosmos infrastructure into a single Layer 1. Start with the interfaces, then go as deep as your application needs.
Use your existing tools
Connect through JSON-RPC, deploy Solidity contracts and work with familiar Ethereum development tools.
Go beyond the EVM
Discover native modules, precompiles and the connections between EVM and Cosmos state.
Know your network
EVM chain ID 125. Cosmos identifier hyperpax_125-1. PAX is the native gas token.
02 / UNDER THE HOOD
Understand the layers. Make them work for you.
Follow a transaction through consensus, execution and storage. Reference guides connect the architecture to the code you will work with.
Trace the execution path
Understand transaction processing, the EVM engine and how chain modules work together.
Build and operate paxd
Compile the node binary, configure services and choose a local or Docker-based setup.
Explore state and storage
Read about the storage engines and how state is represented across the network.
03 / CONNECTED SYSTEMS
Build with context. Settle with clarity.
Connect LayerX activities with Paxeer settlement. Explore the contracts and interfaces for custody, checkpoints and withdrawals.
Connect execution and settlement
Use LayerX for activity execution and Paxeer contracts for custody and settlement.
Explore settlement contracts
Follow the contract responsibilities for checkpoints, bonds, disputes and withdrawals.
Find the right interface
Use EVM JSON-RPC for applications and REST or gRPC for Cosmos module queries.
FROM REFERENCE TO REQUEST
Your first call.
A familiar interface.
Start with your node’s EVM endpoint. Choose a language, copy the request, and check the chain you’re connected to.
