Build your accounts before you deploy.
Visually design, validate, and optimize your Solana PDA schemas. Catch collisions, estimate rent, and generate Anchor code — all before writing a single line of on-chain code.
Every Solana dev has been here
You sketch PDA seeds on paper. Deploy to devnet. Discover a collision. Refactor everything. Repeat. This cycle costs days — sometimes weeks.
Seed collisions kill launches
Two PDAs with overlapping seed structures produce the same address. Your program deploys, then silently corrupts user data. You won't know until it's too late.
Manual PDA math is error-prone
Scribbling seed layouts on sticky notes. Hard-coding bump seeds. Guessing space values. One wrong byte offset and your account data is garbage.
Rent miscalculations waste SOL
Over-allocate and you burn tokens. Under-allocate and your program panics at runtime. There's no visual feedback until you've already deployed.
Lock contention tanks throughput
Your PDA structure looks clean, but under concurrent load, write locks turn your DeFi protocol into a serial queue. 89% contention on a single account.
> What if you could catch all of this before writing any on-chain code?
Everything you need to build better PDAs
From seed composition to collision analysis -- all in one visual workspace.
Design
Drag-and-drop PDA schema designer with visual seed composition. Build account structures with an intuitive node-based editor.
Validate
Instant collision detection and rent estimation across all your PDAs. Catch duplicate addresses before you deploy.
Lock Analysis
Simulate 100 concurrent transactions against your account structure. Identify write-lock bottlenecks and get optimization suggestions.
Generate
Export production-ready Anchor Rust code for your PDA structs, init instructions, and validation logic.
How it works
Four steps from idea to deployment-ready code.
Design Seeds
Define your PDA seeds visually. Combine string literals, pubkeys, and numeric types into seed arrays for each account.
Check Collisions
Run instant collision detection across all your PDAs. See which seed combinations could produce duplicate addresses.
Analyze Locks
Simulate 100 concurrent transactions against your accounts. Find write-lock bottlenecks and get sharding recommendations.
Export Code
Generate production-ready Anchor Rust code with proper account structs, seeds, constraints, and init instructions.
collision-free ≠ contention-free
Your PDAs pass collision checks, but under concurrent load, write locks create bottlenecks. A single hot account can tank your protocol's throughput by 89%.
Skaf's Lock Analysis simulator runs 100 concurrent transactions against your account structure and shows exactly where the locks pile up — before you deploy.
> amm_pool is a critical bottleneck. Consider sharding or partitioning write-heavy accounts.
Why does this happen?
Solana processes transactions in parallel — but only when they don't touch the same accounts. The moment two transactions write to the same PDA, the runtime serializes them.
Write Lock
Solana locks accounts for the duration of a transaction. Write locks are exclusive — only one TX can write to an account at a time.
Read Lock
Read locks are shared — multiple TXs can read the same account simultaneously. But one write lock blocks all readers.
Queue Effect
When 100 TXs target the same writable account, they serialize into a queue. Throughput drops from thousands of TPS to single-digit.
How Lock Analysis works
From your PDA design to actionable optimization — in one click.
