# ACA-Py Feature Overview

> The below contribution is a joint effort between Northern Block and Animo.

## Platform Support

| Platform | Supported | Notes |
| -------- | --------- | ----------------------------------------------- |
| Server | ✅ | |
| Desktop | ⚠️ | Could be run as a local service on the computer |
| iOS | ❌ | |
| Android | ❌ | |
| Browser | ❌ | |

## Agent Types

| Role | Supported | Notes |
| -------- | --------- | ---------------------------------------- |
| Issuer | ✅ | |
| Holder | ✅ | |
| Verifier | ✅ | |
| Mediator | ✅ | Doesn't support the pickup protocol, so only supports implicit pickup of messages. |
| Mediatee | ⚠️ | Doesn't support pickup of messages, but can still be used to coordinate with a mediator to forward messages. (e.g. when I as an individual host my own cloud server and want to use herd privacy so I can't be tracked) |
| Transaction Author | ✅ | |
| Transaction Endorser | ✅

## AIP Support

| AIP Version | Supported | Notes |
| ----------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| AIP 1.0 | ✅ | |
| AIP 2.0 | ⚠️ | Missing support for [0183: Revocation Notification](https://github.com/hyperledger/aries-rfcs/tree/b3a3942ef052039e73cd23d847f42947f8287da2/features/0183-revocation-notification), [0557: Discover Features v2](https://github.com/hyperledger/aries-rfcs/tree/b3a3942ef052039e73cd23d847f42947f8287da2/features/0557-discover-features-v2) and [0627: Static Peer DIDs](https://github.com/hyperledger/aries-rfcs/tree/4739fbf6de07a54c3fee072bd85741422730b3cd/features/0627-static-peer-dids). Also needs to fix some additional AIP1 -> AIP2 interop issues ([AIP-2 base64url consistency](https://github.com/hyperledger/aries-cloudagent-python/pull/1188) and [Small AIP-2 updates](https://github.com/hyperledger/aries-cloudagent-python/pull/1056)) |

## Credential Types

| Credential Type | Supported | Notes |
| --- | -- | -- |
| Indy Credentials | ✅ | |
| W3C Credentials | ✅ | Only JSON-LD Credentials supported with signature suites `Ed25519Signature2018`, `BbsBlsSignature2020` and `BbsBlsSignatureProof2020` |

## DID Methods

| Method | Supported | Notes |
| --- | -- | -- |
| `did:sov` | ✅ | |
| `did:web` | ⚠️ | Can only resolve `did:web`, not create it |
| `did:key` | ✅ | |
| `did:peer` | ⚠️| Indy based `did:peer` dids are used for DIDComm, however the DIDs are not prefixed with `did:peer` yet and are not following the conventions from [RFC 0627: Static Peer DIDs](https://github.com/hyperledger/aries-rfcs/tree/b3a3942ef052039e73cd23d847f42947f8287da2/features/0627-static-peer-dids) |

## Wallet Types

| Wallet types | Supported | Notes |
| -- | -- | -- |
| Indy SDK | ✅ | Indy SDK provides storage, crypto, indy credentials and indy ledger support |
| Aries Askar | ⚠️ | Askar provides storages and crypto support. Released but not fully stable yet. Other Indy features are now handled by Indy CredX and Indy VDR |

| ----------------------------------------------- | --------- | ------------------------------------------------------------------------------------------------- |
| Multi use invitations | ✅ | |
| Invitations using public did | ✅ | |
| Implicit pickup of messages in role of mediator | ✅ | |
| Revocable Indy Credentials | ✅ | |
| Multitenancy | ✅ | [Documentation](https://github.com/hyperledger/aries-cloudagent-python/blob/main/Multitenancy.md) |
| Connectionless (non OOB protocol) | ✅ | Only for issue credential and present proof |
| Signed Attachments | ✅ | needed for OOB |
| Multi ledger support (with automatic detection) | 🚧 | [Pull Request](https://github.com/hyperledger/aries-cloudagent-python/pull/1425) |
| Persistence of mediated messages | ❌ | Messages are currently stored in memory |
| Wallet Import & Export | ⚠️ | Supported in indy-sdk by directly interacting with the indy-sdk. No endpoint availalbe for wallet import & export. Aries Askar doesn't support import & export yet. |
