Recital 84

To ensure the orderly functioning of markets in crypto-assets, crypto-asset service providers operating a trading platform for crypto-assets should have detailed operating rules, should ensure that their systems and procedures are sufficiently resilient, should be subject to pre-trade and post-trade transparency requirements adapted to the markets in crypto-assets, and should set transparent and non-discriminatory rules, based on objective criteria, governing access to their platforms. Crypto-asset service providers operating a trading platform for crypto-assets should also have a transparent fee structure for the services provided to avoid the placing of orders that could contribute to market abuse or disorderly trading conditions. Crypto-asset service providers operating a trading platform for crypto-assets should be able to settle transactions executed on trading platforms on-chain and off-chain, and should ensure a timely settlement. The settlement of transactions should be initiated within 24 hours of a transaction being executed on the trading platform. In the case of an off-chain settlement, the settlement should be initiated on the same business day whereas in the case of an on-chain settlement, the settlement might take longer as it is not controlled by the crypto-asset service provider operating the trading platform.
