Fireballs Meets Codex: Stablecoin Settlement Just Got Instant
Wall Street’s settlement times just got a crypto-sized wake-up call.
Fireblocks—the institutional crypto infrastructure giant—has integrated Codex’s protocol, slashing stablecoin settlement times from days to milliseconds. No more waiting for traditional finance’s plodding rails to catch up.
The move pressures legacy systems still clinging to batch processing like it’s 1999. Because nothing says ’innovation’ like waiting three business days for money to move—unless you’re a bank collecting float revenue, of course.
This isn’t just speed for speed’s sake. Instant settlement unlocks new arbitrage opportunities, tighter liquidity management, and finally makes ’real-time’ more than a buzzword in finance.
Banks: your move. But maybe take your time—we know how you love those T+2 settlements.

Fireblocks provides full support for the official launch of Codex, a purpose-built blockchain for stablecoin finance. Institutions will be able to use Codex from day one through the same secure infrastructure they currently rely on for digital asset operations. Institutions can create Codex wallets to facilitate fund transfers and make payments, with zero additional integration work.

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.
