Evalanche

Avalanche-first agent wallet and execution SDK for AI agents, with multi-EVM support for holdings, payments, DeFi, bridge flows, prediction markets, and perpetuals.

Current Release

• Latest release: v1.12.0
• Published package: evalanche@1.12.0
• Current package surface:
  • Adds first-class Robinhood Chain mainnet support through the named robinhood network alias and chain ID 4663, with official ETH, RPC, explorer, and LI.FI metadata.
  • Extends wallet boot, network switching, MCP chain discovery and switching, and native holdings scans to Robinhood Chain through Evalanche's central EVM registry.
  • Preserves the Robinhood network with RPC overrides supplied through ROBINHOOD_RPC_URLS, EVALANCHE_ROBINHOOD_RPC_URLS, and MCP AVALANCHE_RPC_URL, keeping the selected network alias authoritative.
  • Tests certify Robinhood bridge capabilities through LI.FI native ETH quote construction and prevent non-Gas.zip routes from being mislabeled as Gas.zip.

Install

npm install evalanche

Polymarket authenticated actions use the official polymarket CLI. Install it on production agents and keep it on a pinned path, or set EVALANCHE_POLYMARKET_CLI_BIN=/absolute/path/to/polymarket. Evalanche passes signer material through POLYMARKET_PRIVATE_KEY in the child process environment and never through CLI argv.

Quick Start

import { Evalanche } from 'evalanche';

const { agent } = await Evalanche.boot({ network: 'avalanche' });

console.log(agent.address);

const holdings = await agent.holdings().scan();
console.log(holdings.summary);

const { agent: robinhoodAgent } = await Evalanche.boot({ network: 'robinhood' });
console.log(robinhoodAgent.getChainInfo()); // Robinhood Chain, chain ID 4663

Robinhood's public RPC is rate-limited. For production, set ROBINHOOD_RPC_URLS or EVALANCHE_ROBINHOOD_RPC_URLS to a comma-separated list of provider endpoints. LI.FI bridging is supported when a live route is available; Gas.zip does not currently advertise Robinhood Chain support.

MCP

npx evalanche-mcp

Evalanche ships an MCP server for wallet actions, holdings discovery, DeFi, bridge and swap flows, Polymarket, and perpetual venues. The default MCP transport is stdio. HTTP mode is available for local automation, but requires an explicit bearer token:

EVALANCHE_MCP_HTTP_TOKEN="$(openssl rand -hex 32)" npx evalanche-mcp --http --port 3402

What It Does

• Avalanche-first wallet boot, identity, and agent execution flows
• Unified holdings discovery across wallet balances, DeFi positions, prediction positions, and perp venues
• Cross-chain bridge, swap, and gas-funding flows
• Avalanche and multi-EVM DeFi actions
• Polymarket market reads plus official-CLI-backed execution
• Perpetual trading support for Hyperliquid and dYdX

Also Works Across EVM

Avalanche is the primary path, but Evalanche also supports Robinhood Chain, Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, and other EVM networks for execution and holdings discovery.
