Tunnel in 3 steps
-
Choose how much SOL to send and paste the Ethereum (Base) address that should receive funds on Base mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast SOL to that destination. Once confirmations clear, ETH is pushed to your payout wallet.
Before you broadcast
- Solana confirmations are fast — often under a minute for practical purposes.
- Network outages or congestion can occasionally delay inclusion — check status if stuck.
- Use a Solana mainnet address (base58). Do not send SPL tokens unless the order specifies a token mint.
- Still waiting on ETH? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Solana — high-speed layer-1
SOL is the native token of Solana — built for fast, low-cost transfers and a large ecosystem of on-chain apps.
Solana deposit tips
Send native SOL on Solana mainnet. Token deposits require the exact asset your order lists.
Keep a small SOL balance for rent-exempt account requirements in some wallets.
ETH on Base — Coinbase L2
Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.
Base ETH not received?
Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.
Base ETH payout tips
- Payouts go to Base — verify your wallet network is Base (chain ID 8453).
- Check Basescan with the payout tx hash from your order page.
- Bridging to Ethereum L1 is a separate step after you receive ETH on Base.

Frequently asked questions
Do I need KYC to swap SOL for ETH on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Solana → Ethereum (Base) swaps.
How fast is a SOL → ETH swap?
Most routes settle within minutes. Final timing follows Solana mainnet deposit confirmations and Base mainnet payout speed.
Does TunnelSwap hold my SOL or ETH?
No. You fund the deposit from your wallet and ETH is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for SOL?
Only send on the network shown for the order (Solana mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
