• Wallet UTxO fragmentation

  analyze_wallet_utxos

  How fragmented a Cardano wallet's UTxOs are and what tidying them ("unfracking") would release: UTxO count, native assets and policies, ADA locked as minimum-UTxO deposits, UTxOs that hold a single asset, the largest UTxO, and the projected result of the default UTxO-optimiser plan (transactions needed, UTxOs afterwards, ADA released from deposits, network fees). Read-only: no transaction is built; the user reviews and signs in their own wallet on the page in `url`. Amounts are whole ADA. A wallet with more than 600 UTxOs answers `status: "too_large"`.

• Unsigned swap transaction (nothing is signed or sent)

  build_swap_transaction

  Build an unsigned Cardano swap transaction for a wallet that signs for itself, through the DexHunter aggregator. Returns the transaction as CBOR hex with its hash, what it does (network fee, validity, every output with address, ADA and tokens, and which outputs return to the wallet), the expected and the minimum amount received, the fees (DEX batcher, aggregator and partner fee, network fee, all in ADA), what the trade costs worked out from the transaction itself next to what the aggregator states (`cost`, with a warning when the transaction takes more), and the steps to sign and submit it. Fees are fixed ADA amounts, so a small trade can cost a large share of itself. Realtap never signs, holds keys or submits: nothing happens until the owner of `address` signs the transaction and sends it. Call it only when that owner asked for this trade, and check the token with `get_token` first (liquidity, safety). Limited to a few calls per minute.
