@telaro/langchain

LangChain (JS) tools for Telaro.

Bonds settle on Solana, but trust scores work everywhere.

Drop these tools into any LangChain agent — OpenAI, Anthropic, Gemini, Mistral — to query agent trust scores and gate capital delegation. The agent itself can run on any chain: as long as you can hit our REST API, you can use Solana-bonded reputation as your trust layer.

Install

npm i @telaro/langchain @langchain/core @langchain/openai @langchain/langgraph

Use with createReactAgent

import { ChatOpenAI } from "@langchain/openai";
import { createReactAgent } from "@langchain/langgraph/prebuilt";
import { telaroTools } from "@telaro/langchain";

const tools = telaroTools({
  apiBase: "https://telaro.xyz",
});

const agent = createReactAgent({
  llm: new ChatOpenAI({ model: "gpt-4o-mini" }),
  tools,
});

const reply = await agent.invoke({
  messages: [
    {
      role: "user",
      content:
        "Should I let AgentSenda1JupiterLPv31 swap $1k of USDC for me? " +
        "It claims to be a high-grade trader.",
    },
  ],
});

console.log(reply.messages.at(-1)?.content);
// → The agent calls telaro_check_safety internally,
//   then answers based on real on-chain bond + score data.

Use with Anthropic Claude

import { ChatAnthropic } from "@langchain/anthropic";
import { telaroTools } from "@telaro/langchain";

const llm = new ChatAnthropic({ model: "claude-opus-4" }).bindTools(
  telaroTools()
);

Tools

| Tool | Purpose | |---|---| | telaro_get_agent | Full trust profile by pubkey | | telaro_list | Top agents (optional framework filter) | | telaro_check_safety | (min_bond, min_score) gate check | | telaro_get_claims | Dispute history | | telaro_ecosystem_stats | TVL, dispute rate, totals |

Why this matters for non-Solana agents

Your LangChain agent might run on EVM, Sui, or be entirely off-chain (e.g. an OpenAI Operator). It can still:

1. Read a Solana-bonded agent's trust score before sub-delegating to it
2. Verify the bond is large enough to cover the proposed action
3. Watch dispute history before authorizing recurring activity

The agent's capital stays on its native chain. The reputation oracle is Solana-native, accessed over HTTPS.
