SettleKit

SettleKit is an agentic settlement SDK that executes crosschain DeFi actions as a single, deterministic flow handled by software instead of users.

In the MVP, USDC starts on Base, moves through Arc via CCTP treating Arc as a unified USDC liquidity hub, then is routed to Unichain where SettleKit interacts directly with Uniswap v4 pools to perform the required liquidity provision.

This shows how Uniswap v4 can act as a machine-to-machine execution layer for financial agents, while Arc serves as the settlement layer for cross-chain capital routing. SettleKit abstracts bridging, swapping, and capital deployment into a programmable SDK that enables reliable, transparent, and composable financial automation.

SettleKit is built as a TypeScript SDK that executes a deterministic, multi-step crosschain settlement plan driven by an agent. We use viem wallet and public clients to interact with EVM contracts across Base, Arc, and Unichain. Each action, bridge, swap, and supply, is modeled as part of a single “settlement recipe” that the agent can execute automatically without user intervention. How Arc benefits the project: Arc is treated as a USDC liquidity hub rather than a traditional bridge. By leveraging Circle CCTP through Arc, USDC can move cleanly between chains as part of the routing logic itself. This removes typical bridge friction and allows capital movement to be encoded directly into the settlement pipeline, with predictable fees and fast finality. How Uniswap’s SDK benefits the project: Using Uniswap v4 primitives and tooling, SettleKit interacts directly with pools as part of the execution layer. Swaps are not triggered by UI flows but by the SDK’s routing engine, turning Uniswap v4 into a machine-to-machine execution primitive inside the settlement process. Arc provides reliable crosschain capital routing. Uniswap v4 provides programmable swap execution. SettleKit composes both into a single automated financial flow that ends by supplying assets into Morpho.
