DEX Order Book Aggregation
Agrega DEX order books de múltiplos venues para uma visão unificada, melhorando a visibilidade de liquidez e habilitando cross-exchange trading, sem assumir liquidez aumentada.
DEX Order Book Aggregation é a prática de agregar dados de price-level de múltiplas fontes DEX (on-chain order books ou off-chain data feeds) em uma representação única e padronizada. Aborda heterogeneidade de dados, latência e potenciais duplicatas. Componentes chave incluem: 1) Data Collection: buscando order book data de múltiplos DEXs; 2) Data Standardization: normalizando campos como price, quantity, timestamp e side; 3) Aggregation Logic: combinando múltiplas fontes usando regras para construir uma depth e top-of-book representativas; 4) Data Delivery: entregando a visão agregada para clientes ou smart contracts (via oracles ou on-chain feeds). Ressalvas importantes: a agregação não cria liquidez automaticamente; ela melhora a visibilidade e o potencial de routing, mas a liquidity depth depende da liquidez disponível em cada venue, fees e risk controls. O uso de smart contracts para agregação não é estritamente necessário; muitas implementações são off-chain services alimentando dados para on-chain primitives quando necessário. Trade routing e execution podem alavancar essa visão unificada, mas ocorrem nos respectivos exchanges, com consideração para cross-exchange settlement, slippage e fee accounting.

❓ Perguntas frequentes
What is DEX order book aggregation?
It is the collection and unification of price-level data from multiple DEX sources to form a single view of market depth.
Do I need smart contracts to perform aggregation?
Not necessarily. Aggregation can be performed off-chain and fed to on-chain components via oracles or direct API connections.
Does aggregation increase liquidity?
Aggregation improves visibility and can enable smarter routing, but liquidity depth remains dependent on individual venues and their liquidity.
What are common data sources?
On-chain order book feeds from DEXs or off-chain data feeds provided by nodes and oracles.
What are key risks?
Latency, data inconsistency, duplicate counting, and oracle/trust risk for on-chain feeds.
