Coinspace

Coinspace, operated by the Costa Rica-registered COINIA SRL, is a centralized spot exchange supporting crypto-to-crypto trading in major assets such as BTC, ETH, and USDT without fiat rails, with KYC and two-factor authentication on accounts and cold-hot wallet separation for assets. Technically it runs a hybrid architecture of off-chain matching and on-chain settlement, keeping orders and fills in a database to cut latency while deposits and withdrawals clear through multi-chain gateways by confirmation count, and it exposes a RESTful API for quantitative and aggregation use.

The exchange side serves users with centralized trading needs, with maker and taker fees in conventional tiers, fee reductions for high-frequency traders under platform programs, and book depth maintained with market makers; the wallet side serves daily storage and small swaps. It should be distinguished from the same-named self-custodial wallet product, which is the non-custodial form where users hold their own keys.
