Codex Stablecoin On/Off-Ramp & FX Infrastructure

Stablecoin-Powered On/Off-Ramp and Cross-Border Payments

Codex provides a vertically integrated stablecoin infrastructure stack enabling businesses to convert between fiat currencies and stablecoins — and back again — through a single API integration. The platform combines B2B on-ramp and off-ramp capabilities with a stablecoin-powered FX layer and a purpose-built settlement blockchain, making it a full-stack solution for institutional and fintech cross-border money movement.

Codex API: On-Ramp, Off-Ramp, and Treasury

The Codex API is a developer-friendly REST API enabling businesses to integrate stablecoin money movement into their products and operations without managing the complexity of cross-chain settlement or local banking relationships.

Core capabilities include:

• On-Ramp: Convert fiat currency into stablecoins through Codex-connected partners; funds arrive directly into specified wallet addresses ready for settlement or transfer.
• Off-Ramp: Disburse stablecoin balances to local fiat bank accounts or e-wallets in local currencies, with Codex handling conversion through its local partner network.
• Named Virtual Accounts: Provision local named bank accounts (IBANs) and digital wallets to collect payments in local currencies — without requiring local banking licences.
• Collections and Payouts: Batch disbursement capabilities for high-volume payment operations.
• Treasury Management: Programmatically manage stablecoin treasury balances, track positions, and execute transfers.

Codex FX: Stablecoin-Settled Foreign Exchange

Codex FX is a stablecoin-powered FX layer enabling businesses to send and receive fiat in different currencies faster and at lower cost than traditional correspondent banking rails. Rather than routing through intermediary banks, Codex FX settles cross-currency transactions via the Codex blockchain, achieving near-instantaneous settlement with deterministic finality.

Key benefits over traditional FX:

• Speed: Near-instantaneous settlement versus 1–5 business days for SWIFT/correspondent banking.
• Cost: Eliminates intermediary fees associated with correspondent banking chains.
• Reliability: Blockchain-settled transactions with deterministic finality, eliminating uncertainty and reversals.
• Compliance: Built-in compliance infrastructure suitable for regulated businesses.

Codex Chain: The Settlement Layer

Underpinning the API and FX layer is Codex Chain, an Ethereum Layer 2 blockchain purpose-built for stablecoin money movement. Native USDC (Circle) is live on Codex Chain, and institutional integrations include Fireblocks, Bybit, and GSR, providing deep liquidity and enterprise-grade settlement infrastructure for on/off-ramp operations at institutional scale.
