Swap & Bridge
Cross-chain token swaps and asset bridging — all in one interface, with no KYC and minimal fees.
The Swap & Bridge feature lets you exchange tokens within a single chain or move assets across different blockchains — directly from within James. No account registration with a third party, no identity verification, and no hidden charges. All transactions execute on-chain and are quoted transparently before you confirm.
Whether you are swapping one token for another on the same network or bridging funds from Ethereum to Solana, the interface surfaces the best available route, shows the exact fee breakdown, and lets you confirm in a single step.
How to Use It
Connect your wallet
Connect a browser wallet (MetaMask, Phantom, or any WalletConnect-compatible wallet). Your wallet is used to sign and broadcast the transaction.
Select the source token and chain
Choose the token you want to send and the chain it lives on. Your connected wallet balance is shown automatically.
Select the destination token and chain
Choose the token you want to receive. For a same-chain swap, keep the destination chain the same. For a bridge, select a different chain.
Review the quote
A live quote is fetched showing the output amount, exchange rate, estimated slippage, and all protocol fees. No surprises after confirmation.
Confirm the swap
Approve the transaction in your wallet. The swap or bridge is submitted on-chain. You can track progress in your wallet or a block explorer.
