Paxeer Network Documentation

Build for
High Performance,
on HyperPaxeer.

Getting StartedOpen GitHub

HyperPaxeer Network is a capital orchestration network built as part of the Alexandria Fork upgrade, migrating validators from Paxeer Network (geth PoS, chain ID 229) to a new high-throughput Proof-of-Stake EVM blockchain (chain ID 125) with fast finality and ~2 second blocks.

Technical Architecture.

HyperPaxeer is built using the Cosmos SDK on top of the CometBFT consensus engine, providing full Ethereum compatibility and interoperability with fast finality.

Transactions can be submitted in both Cosmos and EVM formats, enabling developers to scale EVM dApps cross-chain via IBC.

Chain ID (Cosmos): hyperpax_125-1
EVM Chain ID: 125
Token: PAX
Base denom: ahpx
Display denom: hpx
Bech32 prefix: pax

Limitless Boundaries.

No limits. No boundaries. The financial engine for DeFi.

Paxeer Native tooling (MetaMask, Foundry, Hardhat).

```ts
export const network = {
  evmChainId: 125,
  rpc: 'https://mainnet-beta.rpc.hyperpaxeer.com/rpc',
  explorer: 'https://paxscan.paxeer.app',
  nativeSymbol: 'PAX',
};
```

```bash
curl -s https://mainnet-beta.rpc.hyperpaxeer.com/rpc \ 
  -H 'content-type: application/json' \ 
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'
```

Use this snippet to verify your RPC connection and confirm you're on the right network.

Build on a high-throughput network.

  • Fast finality and ~2s blocks (network properties)
  • RPC endpoints and explorer
  • Chain IDs, denoms, and prefixes
  • Validator operations and upgrades
  • EVM compatibility for existing tooling

Architecture & Protocol.

Cosmos SDK + CometBFT

HyperPaxeer is built using the Cosmos SDK on top of the CometBFT consensus engine, providing fast finality, high throughput, and short block times.

EVM compatibility.

HyperPaxeer Network ensures the same developer experience as Ethereum by exposing a fully compatible Web3 JSON-RPC layer and implementing EVM state transitions within a Cosmos chain architecture.

Ethereum tx format

Ethereum transactions represented as Cosmos SDK Tx and Msg interfaces.

secp256k1 keyring

Ethereum secp256k1 curve support for accounts and signing.

StateDB interface

State updates and queries consistent with EVM expectations.

JSON-RPC

Web3 JSON-RPC layer for existing Ethereum clients and tooling.

geth as a library

Code reuse and maintainability through embedded geth components.

Network Information.
