Sweat Wallet's multichain experience is as simple as "1 1 1":
- 1 Wallet — manage assets on any supported chain without creating separate accounts, saving separate keys, or funding each chain with its own gas token.
- 1 Key — the one key you use with Sweat Wallet (social login / Magic Key, upgradable to a seed phrase) manages your accounts on every chain, via NEAR Chain Signatures and an MPC network.
- 1 Token — $SWEAT pays gas on every supported chain. You never need to buy ETH, BNB, or any other gas token — you can literally pay your fees with your feet. The $SWEAT that pays the fee is always taken from your NEAR-side balance; see Paying for transactions on other chains below.
Supported chains: NEAR, Ethereum, Base, Arbitrum, and Binance Smart Chain (BSC). More chains are planned.
Do I need to activate anything?
No — multichain works out of the box. You get a unified view of all your assets across all chains on one screen, and you can send, bridge, swap, buy, and receive any supported token. (Older app versions had a one-tap "Activate Multichain" step; it has been removed — no activation is needed anymore.)
Paying for transactions on other chains
- The fee for a transaction on any chain is paid in $SWEAT drawn from your NEAR-side balance, and it has to be liquid $SWEAT — $SWEAT locked in a Grow Jar cannot pay it. Holding ETH or BNB in your wallet does not help; the app does not use them for fees.
- "Not enough to cover transaction" means exactly that: not enough $SWEAT on the NEAR side. It does not mean you are missing a gas token for the destination chain.
- SWEAT MAX free transactions cover NEAR-network transactions only. Transactions on other chains are charged normally.
- Bringing $SWEAT back from Base or Ethereum to NEAR costs a fee that can exceed 10 $SWEAT, and that fee does not depend on how much you move — bridging a small amount back can cost more than the amount itself. Keep enough liquid $SWEAT on NEAR before you start.
A bridge that looks stuck or "successful" but changed nothing
A bridge attempt can show a success or pending state without having executed. Do not retry it blindly — if the first one is simply delayed, a retry can send twice. Instead:
- Force-refresh your balance in the app.
- Check the transaction in your in-app history.
- Only consider retrying once you have confirmed the source balance is unchanged after the refresh — and if you are unsure, contact support with the transaction hash.
dApps
With WalletConnect you can connect Sweat Wallet to dApps on any supported chain and confirm transactions in the wallet.
