Chainwall
An approval and execution system that rechecks the exact operation against current onchain rules, then runs it through a protected account.
Chainwall is built by OKcontract Labs
OKcontract Labs researches and builds inspectable onchain systems. Chainwall applies that work to privileged operations: smart contracts check the exact call, current approvals, permitted contracts, and protected account path before execution.
Research, open-source foundations, and security products
OKcontract Labs works on transaction specifications, policy-constrained execution, formal methods, and resilient application infrastructure. Chainwall brings those ideas together for teams operating important onchain accounts.
Cells
An open-source reactive state graph for TypeScript applications, built to keep asynchronous state and dependencies understandable.
Verifiable interactions
Human-readable, machine-executable descriptions that let interfaces and automation share one explicit operation intent.
Research and evidence
Public writing, talks, tests, and formal methods that make technical claims easier to inspect.
Keep the final decision inspectable and onchain
The Labs approach becomes concrete product constraints in Chainwall's contracts, SDK, browser console, tests, and security claims.
Contracts make the final decision
Interfaces and services should help people understand and submit actions, but smart contracts should decide whether an action is allowed.
Make access easy to inspect
Teams should be able to see which people, approval rules, workflows, contracts, accounts, and admin paths can affect funds in a protected account.
Delay sensitive changes
Granting new authority should require more approval, time for review, monitoring, and a way to cancel than running a routine action.
Match claims to evidence
Connect each security claim to the contracts, tests, and assumptions that support it.

The Labs site covers the broader work: safer smart-contract interfaces, reusable transaction descriptions, onchain workflows, formal methods, and controls for AI agents that submit transactions.
Selected Talks
Talks and panels from OKcontract Labs on onchain security, AI agents, smart-contract interfaces, censorship resistance, open-source libraries, and verifiable systems.
