n8n-nodes-wax

This is an n8n community node. It lets you use the WAX Blockchain in your n8n workflows.

The WAX Blockchain is a purpose-built blockchain and protocol token designed to make e-commerce transactions faster, easier, and safer for all participants. It's specifically designed for the transfer of digital assets, including NFTs (Non-Fungible Tokens).

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

Operations

This node package provides the following operations for interacting with the WAX Blockchain:

• Get Account Info: Fetch detailed account information from the WAX blockchain
• Get Assets: Retrieve NFT assets owned by an account, with optional filtering by template ID, collection, or schema
• Get Account Token Balance: Get token balance for an account
• Mint Asset: Mint a new AtomicAssets NFT from an existing template
• Create Template: Create a new AtomicAssets template under a collection and schema
• Get Schema Format: Retrieve a schema's field definitions (useful for discovering what to put in Immutable/Mutable Data when minting)
• Transfer Assets: Transfer NFT assets from one account to another
• Transfer Tokens: Transfer tokens (e.g., WAX) from one account to another
• Verify Account: Verify if an account exists on the WAX blockchain
• Buy RAM: Purchase RAM resources for an account on the WAX blockchain
• Stake CPU: Stake WAX tokens for CPU resources on the blockchain
• Stake NET: Stake WAX tokens for network bandwidth resources on the blockchain

Credentials

For operations that require signing transactions (Transfer Tokens, Transfer Assets, Buy RAM, Stake CPU, and Stake NET), you'll need to provide:

• Account Name: Your WAX account name
• Private Key: The private key associated with your WAX account

To obtain a WAX account and private key:

1. Create a WAX account through services like WAX Cloud Wallet
2. Export or generate your private key (keep this secure and never share it)

For read-only operations, no credentials are required, but you'll need to specify the account name as a parameter.

Compatibility

This node requires n8n version 1.0.0 or later.

Security considerations

The credential's private key gives full control of the WAX account. The nodes are designed to keep the key inside n8n's credential store, but a few configuration choices materially affect that:

• API Endpoint. Signed transactions are broadcast through the endpoint you configure. Pointing it at an attacker-controlled RPC node lets that node see every signed transaction this account produces. The nodes validate the URL shape (rejects raw IPs, embedded credentials, and known cloud-metadata hostnames) and require https:// for any operation that signs, but they do not resolve DNS to verify the IP — DNS-rebinding to an internal address is possible for a determined attacker. Only use trusted RPC endpoints.
• Token Contract / Contract field. For Transfer Tokens and Transfer Assets, the Contract parameter is the EOSIO contract whose transfer action gets signed under your active permission. If you bind this field to upstream data (via an n8n expression sourced from outside the workflow), an attacker who can influence that data can swap eosio.token for an arbitrary contract whose transfer action does something destructive. Pin this field to a literal value (e.g., eosio.token, atomicassets) unless you fully trust the upstream source.
• continueOnFail output. When the node is configured with "Continue On Fail", error messages are sanitized to redact strings that look like keys or signatures, but you should still treat any error blob as untrusted before forwarding it to a downstream system (Slack, email, etc.).

Usage

API Endpoints

All nodes allow you to specify the API endpoint to use. The default is https://wax.greymass.com, but you can use any WAX RPC endpoint, such as:

• https://wax.greymass.com
• https://wax.cryptolions.io
• https://wax.dapplica.io

Working with NFTs

When using Transfer Assets operation, you'll need to provide:

• The recipient account name
• Asset IDs (comma-separated list)
• Contract (defaults to "atomicassets")

You can use the Get Assets operation to find the asset IDs of NFTs owned by an account.

Minting NFTs

Both Mint Asset and Create Template operate on the AtomicAssets contract and require the credential's account to be in the target collection's authorized_accounts list. If it isn't, the node fails fast with a clear error before any signature is produced - the collection's author can add it via atomicassets::addcolauth.

Create Template registers a new template in a collection under a specific schema. You provide:

• Collection Name
• Schema Name
• Transferable / Burnable flags
• Max Supply (0 = unlimited)
• Immutable Data: a JSON object whose keys/types match the schema's format (e.g., {"name":"Sword","power":42})

Mint Asset mints one NFT from an existing template. You provide:

• Collection Name
• Template ID (the schema is derived from the template - no need to specify it twice)
• New Asset Owner (recipient account)
• Optional Immutable Data Override / Mutable Data (JSON, validated against the schema)
• Optional Back with Assets: comma-separated EOSIO asset strings (e.g., 1.00000000 WAX) to back the new NFT with

If you don't know what fields the schema expects, run Get Schema Format first - it returns the schema's field definitions so you know what keys/types to put in the Data fields.

Token Operations

For Transfer Tokens and Get Account Token Balance operations, you can specify:

• Token contract (defaults to "eosio.token" for WAX)
• Token symbol (defaults to "WAX")
• Precision (number of decimal places, defaults to 8)

Resource Management Operations

The WAX blockchain requires resources (RAM, CPU, and NET) to perform actions:

For Buy RAM operation:

• Specify the account that will receive the RAM
• Specify the amount of WAX to spend on RAM

For Stake CPU and Stake NET operations:

• Specify the account that will receive the staked resources
• Specify the amount of WAX to stake
• Option to transfer ownership of staked resources to the recipient account (when enabled, the recipient account gains control of the staked tokens)
