Project Background and Challenges

Clients entering the Latin American market need spot trading systems that can seamlessly connect with local fiat currency deposits and withdrawals. Payment habits vary greatly across Latin American countries (such as Brazil's PIX, Mexico's SPEI, Argentina's transfers, etc.), and a single payment channel is not sufficient.

The challenge lies in the unified abstraction of multiple payment channels— It is necessary to enable operations to quickly connect to new channels, while ensuring that each channel's reconciliation is independent and auditable, with a single channel failure not affecting others.

The scope we undertake

Spot trading system, multi-fiat deposit and withdrawal channel integration, unified payment abstraction layer, reconciliation system, localized front-end.

Key technical decisions

Decision 01

Payment abstraction: Direct connectionvsUnified adaptation

Select a unified adaptation layer. New channels only need to be configured; business code does not need to be changed, enabling faster operations and expansion into new countries.

Decision 02

Reconciliation independence

Each channel is reconciled independently; a single fault does not affect overall deposits and withdrawals.

Decision 03

Exchange rates are settled in fiat currency

The exchange rate acquisition and settlement logic between stablecoins and local fiat currencies is separated, reducing the impact of exchange rate fluctuations on accounts.
