Wallet Setup

Fund your wallet with USDC on Solana or Base.

Use a BlockRun API key for account billing: account setup guide. Register at user.blockrun.ai, create a key and add credits. Account mode needs no payment wallet; wallet billing supports Solana first, then Base.

Choose Your Chain

Franklin supports two chains for payments: Solana and Base. Pick one and run the setup command:

bash
# Solana (recommended for new wallets)
franklin setup solana

# Base (also supported)
franklin setup base

Solana first for new wallets

Existing chain selections and Base wallets remain supported. Account API users can skip wallet setup. Unset BLOCKRUN_API_KEY to return to wallet billing.

Check Your Balance

After setup, verify your wallet address and current USDC balance:

bash
franklin balance

This displays your wallet address and USDC balance. Share the address to receive funds.

Fund Your Wallet

Send USDC to the wallet address shown by franklin balance. You can transfer from any exchange (Coinbase, Binance, etc.) or another wallet.

How much do I need?

Even $1 of USDCis enough for hundreds of API calls. Franklin uses micropayments — each model call costs fractions of a cent.

Free Tier

No funding needed to get started. Franklin includes free access to NVIDIA models out of the box. Just run:

bash
franklin

You can use free NVIDIA models immediately — no wallet setup, no USDC, no sign-up required. Fund your wallet later when you want access to premium models like Claude, GPT, and Grok.
