If you prefer using a centralized exchange with deeper liquidity, you can use Coinbase to fund your purchase elsewhere.

Use the "Swap" tab within the wallet to trade your ETH/SOL for IOTA via an integrated decentralized exchange (DEX). 2. Transfer to a Supported Exchange

Transfer those funds to an exchange that supports IOTA, such as Binance , OKX , or Gate.io .

Transfer a base currency like Ethereum (ETH) or Solana (SOL) from your main Coinbase account to your Wallet.
