# Supported Chains & Payments

Blocksmiths accepts USDC payments across four blockchains. All payments are on-chain — there are no credit cards, bank transfers, or fiat gateways.

## Supported Chains

| Chain    | Token | Wallet                          |
| -------- | ----- | ------------------------------- |
| Ethereum | USDC  | Any EVM wallet (via RainbowKit) |
| Base     | USDC  | Any EVM wallet (via RainbowKit) |
| Polygon  | USDC  | Any EVM wallet (via RainbowKit) |
| Solana   | USDC  | Phantom (or any Solana wallet)  |

## How to Pay

### EVM Chains (Ethereum, Base, Polygon)

1. Connect your wallet using the RainbowKit prompt at checkout.
2. Switch to the correct network if prompted.
3. Approve the USDC transfer in your wallet.
4. Wait for the transaction to confirm on-chain.

### Solana

1. Connect your Phantom (or compatible Solana) wallet at checkout.
2. Approve the USDC SPL token transfer.
3. Wait for the transaction to confirm on Solana.

## Why USDC Only?

USDC is a stable, widely-held asset that eliminates price volatility between the time a buyer pays and a vendor receives their payout. Every transaction settles at exactly the price shown at checkout.

## No Fiat, No Intermediaries

Blocksmiths does not process credit cards or hold funds in escrow. Payments go directly on-chain the moment you approve the transaction in your wallet.
