Abstraxn Agent Kit supports Uniswap swaps on EVM chains using your developer Uniswap API key (BYOK). Agents call the uniswap_swap_quote MCP tool; your backend signs approval and swap transactions with the agent wallet accessKey.

​
Supported chains

ethereum, base, polygon, arbitrum-one, bsc

​
Dashboard setup

  1. Open Agentic Stack → Integrations for your application.
  2. Enable Uniswap and paste your API key from developers.uniswap.org.
  3. Save — the key is encrypted server-side and included in agent validation for MCP calls.
The Uniswap key is stored per application, not per end user. All agents under that app share the integration when enabled.

​
Uniswap specialist chat

In the sample web app, open chat with ?serviceAgent=uniswap (or pick the Uniswap category). The backend:
  • Filters tools to Uniswap-relevant MCP calls
  • Injects Uniswap-specific system prompts
  • Routes swap requests to uniswap_swap_quote (not evm_swap_quote)
