# or:  pnpm add @filler-sdk/sdk viem

Status

This package is in active development during ETHGlobal OpenAgents 2026. The public surface (types, errors, chain registry) is ready for downstream integration; runtime implementations of intents / fills / indexer land across Sprint 03 plans.

Quickstart (preview)

import { createFiller, getDeployedAddresses } from '@filler-sdk/sdk';

const filler = createFiller({
  chainId: 130, // Unichain
  account: '0xYourSolverAccount',
  transport: { publicClient, walletClient }, // bring your own viem clients
});

filler.intents.subscribe({ inputTokens: ['0xUSDC...'] }, async (intent) => {
  const result = await filler.fills.execute(intent, /* params */);
  console.log('filled', result.txHash);
});

Sub-path entries

| Import path | What it gives you | | -------------------------------- | -------------------------------------------------- | | @filler-sdk/sdk | createFiller, types, errors, chain registry | | @filler-sdk/sdk/bond | BondClient — stake / unstake / withdraw | | @filler-sdk/sdk/keeperhub | KeeperHub coordination client | | @filler-sdk/sdk/testing | Anvil + mock fixtures for solver tests | | @filler-sdk/sdk/abis | Auto-generated as const ABIs for viem |

Each sub-path is independently tree-shakeable: importing the main entry does NOT pull in the testing/bond/keeperhub bundles.
