About the ETH to TON swap

Why swap ETH to TON. Gram pays every fee on TON and is used across Telegram mini apps and TON DeFi. Swapping ETH to Gram moves value from the Ethereum ecosystem into TON without an exchange.
Which ETH you can use. ETH on Ethereum, Robinhood, Base or Arbitrum One. Over the 90 days to 29 September 2026, most ETH swaps into the TON network on Symbiosis came from Ethereum (77%) and Robinhood (22%).
How it works. In two steps: ETH is swapped to USDT on TON, then USDT is swapped to Gram in your TON wallet. You sign the first step on the network you send ETH from.
Gram and Toncoin. TON’s native coin was renamed from Toncoin to Gram (GRAM) on 15 June 2026 after a community vote; balances and addresses did not change, and the network is still called TON.

More ETH swaps: ETH to USDT, ETH to SOL, ETH to USDC, ETH to BNB.

Swap ETH to TON in Symbiosis PRO mode: 0.4 ETH (Ethereum) to 711.92 GRAM (TON)

How to swap ETH to TON

Approximate example for 7 October 2026: swapping 0.4 ETH (~$1,044) on Ethereum returns about 711.92 GRAM on TON, delivered in about 73 seconds. The router looks at the available liquidity and picks the best combination of price, fee and delivery time. Here is the flow:

Open the swap. Go to the Symbiosis app and connect an Ethereum wallet such as MetaMask. There is no sign-up and no KYC.
Pick the token you send. Choose ETH on Ethereum in the From field.
Choose Gram on TON. Set Gram (TON) as the token to receive and TON as the destination network, and enter your address on TON, for example from Tonkeeper. Enter the amount: 0.4 ETH (~$1,044).
Check the quote. Before you sign, the app shows how much Gram you get, the fee, price impact and time. In this example: about 711.92 GRAM, with 2% slippage tolerance.
Sign and receive. Confirm the transaction in your wallet; the funds reach TON as USDT and are swapped to Gram, which lands in your TON wallet.

ROUTE ESTIMATES

Sample ETH to TON quotes

Approximate figures for 0.4 ETH to Gram from four networks. The swap to USDT on TON was quoted in the Symbiosis app on 7 October 2026; Receive converts it to Gram at the market price of $1.46, without the final swap from USDT to Gram on TON. Fee is the full cost of that quote in USD — the value you send minus the value you receive — plus source-network gas. Time is the median delivery time from each network to TON over the 90 days to 29 September 2026.

Still have questions?

How do I swap ETH to TON?

Connect your Ethereum wallet, pick ETH and its network, choose TON as the destination, enter your TON address, for example from Tonkeeper, and sign. Then complete the swap of USDT to Gram in your TON wallet.

Is Gram the same as Toncoin?

Yes. TON’s native coin was renamed from Toncoin to Gram (GRAM) on 15 June 2026 after a community vote; balances and addresses did not change, and the network is still called TON.

Why does the ETH to TON swap happen in two steps?

Symbiosis delivers USDT on TON first, because that is the main liquidity on the network; the second step turns that USDT into Gram inside TON.

How long does it take to complete the ETH to TON exchange?

Over the 90 days to 29 September 2026, ETH swaps into the TON network on Symbiosis took a median of 34 seconds, and 90% finished within 84 seconds.

Do I need to create an account to exchange ETH to TON?

No. There is no sign-up and no KYC.

Can I swap ETH from Robinhood or Base?

Yes. Choose the network your ETH is on as the source; the rest of the flow is the same.

Do I need Gram for the second step?

A small TON network fee applies to the swap inside TON; it is paid in Gram unless your wallet covers it.

Can I swap TON back to ETH?

Yes. Choose Gram or USDT on TON as the source and ETH on the network you want as the destination.
