Suiquencer

Suiquencer is a visual DeFi flow builder for the Sui blockchain that lets users design multi‑step transaction sequences on a node‑based canvas and execute them in a single atomic transaction.

It supports wallet connection, live balances, swaps via Cetus, lending via Scallop, cross‑chain bridging via LI.FI to other chains and protocols, conditional logic and branching, SuiNS/ENS resolution style, and custom Move contract calls for complete freedom. Flows auto‑save, support tabs, and provide execution ordering with effective balance tracking for transparent, safe automation.

Under the hood, Suiquencer turns each connected node into a deterministic execution plan. It topologically sorts the graph from the Wallet entry point, validates inputs at every step, tracks effective balances across the sequence, and builds a single TransactionBlock so on‑chain steps succeed or fail together. Bridge actions are queued and executed after the atomic Sui transaction, keeping cross‑chain routing safe and explicit while preserving a clean, visual workflow.

Suiquencer leverages Sui Programmable Transaction Blocks (PTBs) to compile each flow into a single atomic transaction. Similar product been explored for EVMs using EIP-7702, but given market sentiment and exploration of other L1s this is a full-rewrite for architecture of SUI blockchain and non-EVM showcasing alternative non-forked protocols that comes with this chain. Initial inspiration comes from rawbit.io expanding simple React Flow canvas into something unique focusing deeply on SUI fundamental differences in the transaction setup.

Suiquencer is built from scratch delivering tightly integrated stack where each layer feeds the next. The UI is a node‑based editor for drag/drop flows, edges, zoom/pan, and layout, while custom node panels handle configuration, validation, and live previews. A shared React state model keeps the graph structure, node settings, and execution ordering in sync, so the canvas, sidebar, and preview timeline always reflect the same flow.

On‑chain connectivity uses Mysten’s wallet + RPC tooling with SuiNS name support so users can work with human‑readable addresses. Protocol integrations are real SDKs rather than mock data: Cetus provides swap routes and quotes, Scallop supplies lending rates and receipt tokens, and LI.FI powers cross‑chain routing to EVM networks and protocols on demand. Live protocol data feeds into the UI so users can preview outcomes before execution.

Suiquencer also includes Pro Mode features and product‑level plumbing: flows auto‑save to localStorage, the editor supports multi‑tab workspaces, JSON import/export for sharing and versioning, and a right‑side execution timeline that mirrors the graph. The result is a cohesive system where the visual editor, protocol data, and execution pipeline stay consistent.
