Our take
bity
Bity provides a non-custodial fiat gateway and crypto brokerage established in Neuchâtel, Switzerland. Operating since 2014, the service connects European banking rails including SEPA and Swiss domestic transfers directly to on-chain cryptocurrency deliveries. Unlike centralized trading hubs that hold account balances on centralized ledgers, Bity functions as a direct execution intermediary. Purchased assets settle immediately into personal self-custody addresses, while crypto sales convert into bank payouts or physical cash through its regional ATM network.
This operational architecture eliminates counterparty insolvency custody exposure, appealing directly to users who prioritize wallet autonomy and Swiss regulatory standards. The tradeoff emerges in transaction costs, as integrated broker fees and network mining charges exceed standard maker and taker tiers on deep order books. For retail buyers and institutional clients demanding direct on-ramp execution without exchange-side asset custody, Bity delivers a focused and transparent Swiss service.
dYdX
dYdX represents a mature technical model for decentralized perpetual trading. By migrating from Ethereum layer-2 networks to a purpose-built standalone Cosmos appchain, the platform delivers central limit order book functionality with sub-second order matching while preserving self-custody. Traders maintain direct authority over their assets through web3 wallets, avoiding the solvency risks associated with centralized trading venues. The trading experience closely replicates traditional derivatives platforms, offering advanced order types, programmatic API access, and tiered fee structures based on monthly trading volume.
However, the protocol is specialized rather than universal. It focuses squarely on perpetual derivatives settled in stablecoins rather than physical spot swaps or fiat on-ramps. Additionally, strict frontend compliance filters block users in restricted regions, and moving capital into the standalone chain requires bridging steps that introduce operational overhead for casual market participants.
