Oak Security’s Faster Path from Solana to Arbitrum

When Stylus launched on Arbitrum, the value for Solana teams was easy to understand. They could keep working in Rust while gaining access to Ethereum liquidity, infrastructure, and the wider EVM ecosystem. What looked straightforward in theory, though, was more complicated in practice. Even when both environments use Rust, migration still means adapting to a different execution model, different storage patterns, and different approaches to permissions and contract interaction.

That is the problem Oak Security set out to solve with StylusPort. Instead of treating migration as a one-off engineering effort, Oak built a structured workflow for translating Solana programs into Stylus contracts. That makes Arbitrum the only EVM path where teams can bring Rust-based smart contract logic onchain without first converting the project into a Solidity codebase. The result is a more practical path to shipping on Arbitrum for teams that want to bring existing Rust-based applications onchain without taking on a full Solidity rewrite from day one.

This also has a direct business implication. When teams already have core logic, internal expertise, and development processes built around Rust, a migration path that preserves more of that investment can reduce rewrite overhead and make an onchain roadmap easier to justify. For institutions and enterprises especially, that can mean testing an Arbitrum strategy without first committing to a much larger platform reset, including the time, budget, and hiring required to rebuild core logic for a different smart contract environment.

The problem with Solana-to-EVM migration today

For many teams, expanding into the EVM is not just a technical decision. It is a commercial one. Arbitrum gives builders a way into Ethereum’s user base, liquidity, tooling, and interoperability while delivering familiar high throughput and low fees. For teams thinking about growth, that makes Arbitrum a compelling destination.

The difficulty is that shared Rust alone does not make migration simple. Solana and Stylus may use the same language, but they organize programs differently. Solana passes accounts into programs at runtime, while Stylus contracts manage their own storage in a more familiar EVM pattern. Permissions, state management, and external calls also need to be reworked. In practice, that means migration is less about copying code and more about translating architecture.

That is where projects tend to slow down. Without a clear process, teams are left piecing together docs, examples, and guesswork. For a smaller company, that creates engineering drag. For an enterprise team, it can turn a promising Arbitrum roadmap into a larger rewrite effort with more cost, more delay, and more execution risk.

How Oak turned migration into a workflow with StylusPort

Oak’s contribution was to make that translation process more systematic.

StylusPort combines a migration handbook with an MCP server for AI-assisted workflows. The handbook lays out how to map major Solana patterns into Stylus, covering areas like storage, access control, external calls, token handling, testing, and security considerations. The MCP server brings that guidance into the workflow itself, with tools for project detection, boilerplate generation, handbook search, and guided planning and execution.

That matters because the hardest part of migration is not syntax. It is understanding how one runtime model should map to another. Teams need more than a list of differences. They need a usable path from existing Solana code to a workable Stylus implementation. Oak’s work reduces how much of that translation has to be figured out from scratch, which is why StylusPort is best understood as a time-to-market tool rather than just a migration resource.

Why Oak’s model is credible in production

Oak also grounded StylusPort in real code, which makes the case study much stronger. The handbook includes a full migration of Bonfida’s token vesting program, and Oak tested StylusPort on Coral’s production multisig. Coral is a meaningful example to use because a multisig is more than a simple wallet. It has to manage owner sets, signature thresholds, transaction creation, approval flow, and gated execution for sensitive actions such as upgrades or asset control. 

In the Coral example, the planning workflow generated architecture mappings and a risk register, while the execution workflow produced a compiling Stylus contract with 23 unit tests from roughly 300 lines of Anchor Rust. Note that Oak does not present that output as finished production code but rather as a strong starting point. StylusPort does not automate judgment away, but it does make real migration work move faster.

Oak also applied its own security standards to the tooling itself. The team ran a blinded audit against the MCP server, fixed the issues it found, and published the report. 

Why Stylus and Arbitrum were the right fit

Stylus is what makes this workflow valuable. Because it supports Rust while remaining EVM-compatible, teams can carry more of their existing engineering context into Arbitrum while gaining access to Ethereum-native infrastructure and interoperability. That is a much more practical path than asking a Rust team to rewrite core functions in Solidity before it can even evaluate the move.

It also expands what teams can realistically consider bringing onchain. For institutions and enterprises with Rust-based systems, that can mean moving more sophisticated control logic, validation rules, or workflow layers closer to execution without treating the project as a full platform rewrite.

What this changes for teams and the business

Before StylusPort, a move from Solana to Arbitrum often meant piecing the path together by hand. Oak turned that into a more structured workflow for planning, executing, and validating the move. The immediate benefit is a faster path to market for Rust teams. The broader business impact is that Arbitrum becomes a more realistic destination for teams that want Ethereum access without absorbing the cost of a full Solidity reset.
