Modular, Composable, Scalable

Veramo was designed from the ground up to be flexible and modular making it highly scalable. Create an agent, add plugins, run on server or mobile. You can also expose your agent over REST.

Awesome CLI

The Veramo core API is exposed by our CLI tool. Get started quickly creating DIDs and VCs from your terminal or run a local cloud agent. Developers will love the plugin development tools included.

Multi-Platform

Veramo runs on Node, Browsers, and React Native right out of the box.

Clean API backed by TypeScript

Veramo has a simple and clean API that is easy to reason about. This example bootstraps your agent with minimal configuration.

  import { createAgent } from '@veramo/core'
  import { KeyManager } from '@veramo/key-manager'
  import { DIDManager } from '@veramo/did-manager'
  import { CredentialIssuer } from '@veramo/credential-w3c'

  /* Configure the agent */
  const agent = createAgent({
    plugins: [
      new KeyManager(/* config */),
      new DIDManager(/* config */),
      new CredentialIssuer(),
    ],
  })

  /* Create an identifier and optionally link to an existing user */
  const user = await agent.didManagerGetOrCreate({
    alias: 'alice'
  })

  const verifiableCredential = await agent.createVerifiableCredential({
    credential: {
      issuer: { id: 'did:web:sun.veramo.dev' },
      credentialSubject: {
        id: user.did,
        tutorial: 42,
        status: 'completed'
      }
    },
    proofFormat: 'jwt',
    save: false
  })
