BlockForecast does not offer fiat onramps directly. You bring crypto in; the platform takes it from there. Local fiat-to-crypto methods (P2P, regional exchanges, etc.) live with their respective providers and are outside BlockForecast’s scope.
BlockForecast uses native USDC on Base — not USDC.e (bridged USDC) or USDC on Ethereum mainnet. The in-app bridge always delivers native USDC, so you don’t need to worry about this when using Path 1. If you arrive at the platform with bridged USDC, swap to native via Uniswap on Base before trading.
Choose your path
- Path 1 — In-app bridge (recommended)
- Path 2 — CEX withdrawal to Base
- Path 3 — Bridge from Ethereum mainnet
The in-app bridge uses the LI.FI routing protocol to accept any crypto on any chain and automatically swap and bridge to USDC on Base. One transaction signature — no separate bridge step required. Works in every country.
Sign in to BlockForecast
Go to blockforecast.io and sign in with Google, Apple, email, or your Web3 wallet. If you use Google, Apple, or email, BlockForecast automatically creates an embedded wallet for you via Privy — no seed phrase or browser extension required.
Find the Deposit section
Scroll to the Deposit section. The bridge widget is embedded directly in the page.
Choose your source asset and chain
Select the network you’re bridging from — Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Solana, and others are all supported. Then pick the token you want to send: ETH, SOL, USDT, USDC on another chain, MATIC, ARB, BTC (as WBTC), and more.
Enter the amount
Type in how much you want to deposit. The widget shows the estimated USDC on Base you’ll receive after swap and bridge fees (typically 0.1–0.4% of the amount, plus source-chain gas).
Don’t have a wallet yet?
When you sign in with Google, Apple, or email, BlockForecast automatically creates an embedded Base wallet for you via Privy. No seed phrase to back up, no browser extension to install. You can bring USDC to that wallet immediately. If you prefer self-custody:- Coinbase Wallet — best native Base experience
- MetaMask — universal; add Base as a custom network
- Rainbow — clean UX with Base support built in
Common mistakes
Wrong network on a CEX withdrawal
Wrong network on a CEX withdrawal
Always select Base as the network when withdrawing USDC from an exchange. Choosing Ethereum, Polygon, or BNB Chain sends funds to the wrong chain. The in-app bridge (Path 1) avoids this entirely since it always delivers to Base.
Ending up with USDC.e instead of native USDC
Ending up with USDC.e instead of native USDC
Some older bridge setups deliver USDC.e (bridged USDC). BlockForecast requires native USDC on Base. If you end up with USDC.e, swap it to native USDC via Uniswap on Base (small fee applies). Path 1 always delivers native USDC.
Insufficient ETH for Base gas
Insufficient ETH for Base gas
Base transactions require a small amount of ETH for gas — typically fractions of a cent. If your wallet has USDC but no ETH, you won’t be able to submit transactions. The in-app bridge handles this automatically. For manual setups, bridge a small amount of ETH to Base alongside your USDC.
