Cross-chain & bridging
Buying on another chain, moving funds between chains, and why every chain needs a little gas.
Yes. Torch bridges your funds to the token's chain and then buys, in one flow. The quote shows both parts: a 0.15% bridge fee and the normal trading fee.
The bridge part worked; the buy part didn't (the price moved, or price impact needed your confirmation). Your money is safe on the token's chain. Tap Buy again: it's now a normal buy there, using the funds that just arrived. Nothing was lost.
Torch keeps a small amount of that chain's gas token in your wallet, so you can sell the token later without having to top up first. It's yours and shows in your portfolio.
Bridges are run by independent providers. Most arrive within seconds, depending on the speed of the blockchains involved; busy networks can take longer. Once your side of the bridge confirmed, the funds are on their way, not lost. The bridge screen shows the status and an explorer link.
If the bridge provider couldn't fill it, the funds are returned to your wallet on the chain they came from. The status shows Refunded when that's done. If it still looks stuck after an hour, contact support with the explorer link.
Every bridge has a minimum, because network and provider fees would eat a tiny amount. Bridge a larger amount.
The bridge providers can't move funds on that route at the moment (for example they're out of capacity on that chain). It's usually temporary. Try again later, or pay with funds already on the token's chain.
Every chain charges its own network fee in its own gas token: ETH on Robinhood, Ethereum, Base, Arbitrum and Ink; SOL on Solana; BNB on BNB Smart Chain; a dollar stablecoin on Stable and Arc. Keep a little of each chain's gas token where you trade, so you can always sell.
Solana needs a small amount of SOL for every transaction, even to swap USDC into SOL. Send about 0.01 SOL to your Torch Solana address, then trade normally.
Use Bridge (/bridge in the bot or the Bridge page in the Terminal). Pick the source, the destination and the amount; the quote shows what arrives and the fees.
