Feel free to test it, we would appreciate feedback to address any errors that may occur

An industry-leading API that helps secure wallets by providing a list of all token and NFT contracts that can spend on a wallet's behalf. The API includes the allowance granted in approvals, value-at-risk and a risk assessment.

Commonly used to add revoke features in wallets and for onchain risk analysis.

A list of approvals is provided across all token contracts categorized by spenders for a wallet’s assets. If the spender account were to be hacked, the value-at-risk is the amount the wallet could stand to lose.

Note - by purchasing this add-on, you get access to ALL the other Covalent add-ons in the marketplace.

Getting Started

There are 3 primary developer tools for using the Security API:
1. Unified API - enterprise-grade endpoints to use with any programming language. Switch blockchains with one path parameter.

curl -X GET\? \
    -H 'Content-Type: application/json' \
    -u YOUR_API_KEY:

2. Client SDKs - official client libraries for TypeScript, Go and Python.

import { CovalentClient } from "@covalenthq/client-sdk";

(async () => {
   const client = new CovalentClient("YOUR_API_KEY");
   try {
    const approvals = client.SecurityService.getNftApprovals("eth-mainnet", "demo.eth");
} catch (error) {

3. GoldRush Kit - beautifully designed React components for your dApp frontend
