@xpla/evm

Chain definition and precompile addresses/ABIs for XPLA EVM (viem).

Installation

pnpm add @xpla/evm viem

Usage

Chain (viem)

import { conxMainnet, conxTestnet, conxLocal } from '@xpla/evm';
import { createPublicClient, http } from 'viem';

const client = createPublicClient({
  chain: conxMainnet,
  transport: http(),
});

Precompile addresses and ABI

Each precompile is exported as { abi, address } for use with viem (full type inference for writeContract / readContract):

import { bank, type CoinStruct, type PageRequestStruct } from '@xpla/evm/precompiles';
import { getContract, createPublicClient, http, writeContract } from 'viem';
import { conxMainnet } from '@xpla/evm';

const publicClient = createPublicClient({
  chain: conxMainnet,
  transport: http(),
});
const bankContract = getContract({
  ...bank,
  client: publicClient,
});
const balance = await bankContract.read.balance([address, denom]);

// writeContract with inferred function names and args
await writeContract(publicClient, { ...bank, functionName: 'send', args: [/* ... */] });

Legacy: PRECOMPILE_ADDRESSES and *_PRECOMPILE_ABI constants are still exported but deprecated; prefer auth, bank, wasm, bech32, distribution, gov, slashing, staking.
