Configuration

The Mint application is configured via environment variables. All public configuration uses the NUXT_PUBLIC_ prefix and can be set in a .env file in the app directory.

cp app/base/.env.example app/base/.env

General

Variable	Default	Description
NUXT_PUBLIC_TITLE	Mint	Application title
NUXT_PUBLIC_DESCRIPTION	To mint is a human right.	Application description
NUXT_PUBLIC_DOMAIN	localhost	Domain for subdomain-based artist scoping
NUXT_SSR	true	Enable/disable server side rendering
NITRO_PRESET	node_cluster	Nitro server preset

Chain

Variable	Default	Description
NUXT_PUBLIC_CHAIN_ID	1	Target chain (1 for mainnet, 11155111 for Sepolia)
NUXT_PUBLIC_FACTORY_ADDRESS		Factory contract address for the target chain
NUXT_PUBLIC_BLOCK_EXPLORER	https://etherscan.io	Block explorer URL
NUXT_PUBLIC_RPC1	https://eth.llamarpc.com	Primary RPC endpoint
NUXT_PUBLIC_RPC2		Fallback RPC endpoint
NUXT_PUBLIC_RPC3		Fallback RPC endpoint
NUXT_PUBLIC_MAINNET_RPC1	https://eth.llamarpc.com	Mainnet RPC (for ENS resolution on non-mainnet chains)

Artist Scope

Variable	Default	Description
NUXT_PUBLIC_CREATOR_ADDRESS		Scope app to a single artist address

When set, the app only shows the configured artist's collections. This can also be set via URL subdomains (e.g. artist.mint.example.com).

Mint Defaults

Configure the default mint amount and target value for the mint input.

Variable	Query Param	Default	Description
NUXT_PUBLIC_MINT_AMOUNT	?amount=N	1	Default number of tokens to mint
NUXT_PUBLIC_MINT_VALUE	?value=N	0 (off)	Target USD value for dynamic default amount

Query parameters take precedence over environment variables.

Static Default

Set a fixed default mint amount:

NUXT_PUBLIC_MINT_AMOUNT=10

This sets the mint input to 10 by default.

Dynamic Default (Target USD Value)

Set MINT_VALUE to automatically compute how many tokens to mint for a target dollar amount. The count updates reactively based on the current gas price and ETH/USD exchange rate (via Chainlink).

NUXT_PUBLIC_MINT_VALUE=5

At a gas price of 10 gwei and ETH at $3,000, this would default to ~3 tokens (each costing ~$1.80). The amount always floors at 1 token, even if a single unit exceeds the target value.

When MINT_VALUE is set, it takes precedence over MINT_AMOUNT.

Query Parameter Override

All mint defaults can be overridden per-page via query parameters, useful for sharing links with pre-configured amounts:

https://mint.example.com/artist/collection/1?amount=100
https://mint.example.com/artist/collection/1?value=5

Services

Variable	Default	Description
NUXT_PUBLIC_WALLET_CONNECT_PROJECT_ID		WalletConnect project ID
NUXT_PUBLIC_IPFS_GATEWAY	https://ipfs.io/ipfs/	IPFS gateway URL
NUXT_PUBLIC_ARWEAVE_GATEWAY	https://arweave.net/	Arweave gateway URL
