Defined once and used consistently across every page here. Several of these terms are relied upon to sound reassuring to someone meeting them for the first time.

A definition list of exchange and custody terms

Custody

Who holds the asset, and under what arrangement.

  • Custodial — the venue holds the asset on your behalf. You hold a claim against the venue.
  • Non-custodial or self-custody — you hold the private keys. Nobody can freeze the asset and nobody can restore it for you.
  • Segregated — client assets are kept separate from the operator's own and identified as belonging to clients.
  • Omnibus or pooled — client assets are held together in shared wallets, with an internal ledger recording who owns what.
  • Rehypothecation — the venue reusing client assets for its own purposes, such as lending them out.
  • Proof of reserves — evidence that a venue controlled certain assets at a moment in time. Stronger when it also covers liabilities and is independently performed.

Regulation

What a permission is, and what it attaches to.

  • Register — the regulator's own public list of authorised firms, searchable by name or number.
  • Warning list — the regulator's public list of firms it has warned the public about.
  • Operating entity — the named company you are actually contracting with, stated in the terms and frequently not the brand.
  • AML registration — supervision for anti-money-laundering purposes, which is not authorisation of the investment activity.
  • Deposit protection — a compensation scheme covering certain deposits on a firm's failure. Cryptoassets are frequently outside it.

Cost

Every place the money goes.

  • Maker fee — charged on an order that rests in the book and adds liquidity. Usually the cheaper side.
  • Taker fee — charged on an order that executes immediately against the book.
  • Spread markup — margin built into a quoted price rather than charged as a fee. On zero-commission venues this is usually the whole cost.
  • Funding rate — a periodic payment between long and short holders of a perpetual contract, set by the imbalance between them.
  • Conversion margin — the difference between the rate applied to a currency conversion and the market rate.
  • Network fee — paid to the blockchain rather than to the venue, and worth separating from the venue's own charge.

Withdrawals

The vocabulary of the exit.

  • Test withdrawal — a small withdrawal made deliberately to observe how the venue behaves before committing more.
  • Pending — requested and not yet sent. Ordinary in itself; informative when it does not resolve.
  • Address whitelisting — a holding period after adding a new withdrawal destination, which is a genuine anti-theft measure.
  • Release fee — a payment demanded before funds can be sent out. A legitimate charge is deducted from the amount, not requested in advance.
  • Minimum withdrawal — a floor below which funds cannot be moved, which can strand a small balance.
