To date, Fireblocks supports over 2,000 institutions globally, including exchanges, custodians, banks, and market makers. It has processed more than $10 trillion of transfers in 300 million wallets. Fireblocks supported Codex at launch to continue the operational continuity and compliance of stablecoin settlement.

Architecture for Optimized Stability and Scalability of Stablecoin Payments

For stablecoin transactions, legacy blockchains are built to solve these limitations with Codex. It features low and predictable fees that can be payable in stablecoins, and of course, there is no price volatility associated with gas costs. It settles all activity on Ethereum, anchoring transactions to a widely adopted and secure smart contract blockchain.

Codex is designed to scale, handling thousands of transactions each second. It is fully EVM equivalent, allowing developers to deploy existing Ethereum-based smart contracts without changes. This compatibility introduces faster onboarding and effective contract management for developers and institutions.

Support for Real-World Use Cases and Ecosystem Growth

From launch, Codex delivers deep on-chain liquidity, on which stablecoin flows can be realized in real time for cross-border payments and FX operations. The ecosystem’s incentives encourage adoption and promote sustainable network usage across financial applications.

Codex co-founder Victor Yaw says the Fireblocks integration is designed to meet the trust and tooling needs of institutional partners. The collaboration aims to catalyze Codex’s mission to become a foundational settlement layer for global stablecoin use in regulated financial environments.
