Roadmap

Codex’s development follows a phased rollout strategy designed to rapidly bring programmable fiat ↔ crypto infrastructure to market while layering in technical and economic guarantees over time.

This approach ensures that Codex can begin facilitating real-world integrations early, while progressively introducing features like validator accountability, stablecoin-native primitives, and developer-facing tooling.

Phase 1 - Limited Mainnet

Codex has launched its core EVM execution layer as an OP Stack-based rollup on Ethereum Mainnet. This includes:

EVM Equivalence: Full smart contract and tooling compatibility with Ethereum
Stablecoin Gas Payments (Partial): Initial gas usage still denominated in ETH, with stablecoin support on the roadmap
Custody Support: Early integrations with Safe, Fireblocks, and DFNS
Cross-Chain Messaging: LayerZero support for interoperability
Sequencer: Operated via Conduit to ensure low latency and reliable performance

Phase 2 - Native Stablecoin Issuance

This phase will focus on deploying natively issued, onchain stablecoins on Codex with direct bridging and mint/redeem flows:

Native USDC on Codex: Eliminates bridging risk and enables seamless mint/redeem directly with Circle
Other Native Stables: Support for additional fiat-backed or synthetic stablecoins
Onchain Issuance Primitives: Designed for direct integration into payment, FX, and treasury flows
Bridging Contracts: Custom bridges built for direct issuance flows (not synthetic wrappers)

Phase 3 - Core Features

This phase will focus on building out protocol-level features to unlock composability, trust minimization, and programmable guarantees:

Validator Network: Validators become economically accountable for fiat ↔ crypto settlement
Slashing Enforcement: Validators must fulfill fiat delivery obligations, or risk penalties
Cancellation-First Ordering: Sequencer-level prioritization for market maker cancel orders, enabling tighter FX spreads
Fee Refund Auctions: Second-price auction mechanism to reduce gas cost overpayment
On/Off-Ramp Transaction Types: Custom EVM-native txs for verifiable fiat movement
Ramp Compliance Logic (Precompiles): Business rules embedded directly into execution

Phase 4 - SDKs, APIs, and Integration Tooling

This phase will release first-party tooling for developers and financial institutions:

Ramp & Wallet SDKs: Onboard users with built-in KYB flows, transaction formatting, and metadata hooks
Institutional APIs: Enterprise-facing interfaces to integrate directly with validators and custody infrastructure
Developer Dashboard: Tools for contract deployment, ramp testing, and observability
Docs & Standards: Formal interfaces for building and registering ramps, issuers, and validators
