Aggregator

Find routes across Arc liquidity and prepare swaps with the TypeScript SDK.

npm latest (checked 2026-09-15): 1.0.0.

Arc Aggregator searches available liquidity sources for a route between two tokens. Use @masterpeach/arc-aggregator-sdk to preview the result, show the user the net output and minimum they will accept, then prepare a transaction for Arc Execution Router after confirmation. The application submits that transaction through a wallet.

• Overview — package, execution flows, configuration, and Launchpad support.
• Quickstart — install, prepare, approve, simulate, and submit with viem.
• Core Features — client configuration, quotes and routing, slippage, fees, transaction safety, and direct and delegated swaps.
• Changelog — published versions and migration from 0.1.x.

Launchpad tokens can trade through the Aggregator before graduation and, after Uniswap V4 pool creation, continue trading through the Aggregator on V4. See Trading before and after graduation.

The examples pin @masterpeach/arc-aggregator-sdk@1.0.0, the stable npm release published on 2026-09-15. It includes the two-step API, V4 bytes32 pool IDs and deadline clock-skew handling. Use this version for these Testnet examples; do not infer mainnet API availability from the package version.
