Gates

The GateSDK manages the Akita gate system — a composable access control mechanism with 16 different subgate types. Gates can be used to restrict who can perform specific operations.

Concepts

Gate Architecture

The gate system has two layers:

1. Gate contract — The main gate that coordinates subgate checks
2. Subgates — Individual contracts that check specific conditions

A gate check passes if the caller satisfies all required subgates (AND logic).

Subgate Types

Subgate	Description
Asset Gate	Requires holding a minimum amount of a specific ASA
Akita Referrer Gate	Requires being referred by a registered referrer
Merkle Address Gate	Requires address to be in a merkle tree (allowlist)
Merkle Asset Gate	Requires holding an asset from a merkle tree set
NFD Gate	Requires owning a specific NFD (Non-Fungible Domain)
NFD Root Gate	Requires owning an NFD under a specific root
Poll Gate	Requires having voted in a specific poll
Social Activity Gate	Requires minimum social activity level
Social Follower Count Gate	Requires minimum follower count
Social Follower Index Gate	Requires following specific accounts
Social Impact Gate	Requires minimum social impact score
Social Moderator Gate	Requires moderator status
Staking Amount Gate	Requires staking a minimum amount
Staking Power Gate	Requires minimum staking power
Subscription Gate	Requires an active subscription to a service

Initialization

import { GateSDK } from '@akta/sdk/gates'

const gate = new GateSDK({ algorand })

Use Cases

Token-Gating a Feature

Use the Asset Gate to require holding a minimum token balance:

Gate + Asset Subgate (min 1000 AKTA) → Only AKTA holders

Allowlist Access

Use the Merkle Address Gate with a merkle tree of approved addresses:

Gate + Merkle Address Subgate → Only allowlisted addresses

Reputation-Based Access

Combine multiple social gates:

Gate + Social Impact Subgate (min 100)
     + Social Follower Count Subgate (min 50)
     → Reputable community members only

Subscriber-Only Features

Gate + Subscription Subgate (service ID)
     + Subscription Streak Subgate (min 3 payments)
     → Active subscribers with payment history

Integration with Wallet Plugins

Gates integrate with the wallet plugin system through the GatePlugin. When a gate plugin is installed on a wallet, it can gate any plugin execution:

Wallet → Gate Plugin → Check subgates → Allow/Deny → Execute plugin

See Wallet Plugins for gate plugin usage.
