​
Swap

Trade one token for another on the same chain. Protos quotes the route and returns calldata your wallet signs.

​
Bridge

Move a token from one chain to another. Protos compares bridges and picks the cheapest path, then returns the transaction.

​
Buy & sell

Shorthand for an execution. Protos asks for the amount, then builds the quote.
If you say “buy” or “sell” without an amount, Protos prompts you for one instead of guessing.

​
Rebalance across chains

Split a single move across multiple chains in one request:
Protos divides the amount across legs, resolves each leg independently, and shows every leg’s quote before you sign anything.

​
Before you sign

Every quote is re-simulated immediately before signing — if the route would revert (slippage moved, liquidity changed), Protos rejects it and tells you instead of letting a bad transaction through. This applies to single-leg swaps, every leg of a rebalance, and Solana routes.

​
What you’re signing

Protos never signs on your behalf. Every command above returns:
  • The quote — output amount, fees, gas, ETA for cross-chain routes.
  • An approval step, if the source token needs one.
  • Unsigned calldata for the actual transaction.
You review it and tap to sign in your own connected wallet. If you don’t have funds on the destination chain, Protos offers to fund it rather than failing silently.
