WAASDK
Built on Sequence's smart contract stack

Wallet infrastructure
for a gasless, batched
Web3.

Session keys, EIP-7702 batching, and sponsored transactions via Permit2 and ERC-2612 — non-custodial, multi-chain, orchestrated through a staged smart-contract pipeline.

Core architecture

What's actually running under the hood

Non-Custodial

Session keys scoped to specific contracts and time windows — the platform never holds user keys.

Multi-Chain Hub

CREATE2 singleton deployment — the same wallet address on Ethereum, Base, Arbitrum, and beyond.

Gas Sponsorship

Permit2 and ERC-2612 approvals signed off-chain, executed by a sponsor wallet — zero native gas required.

Batched Execution

Multicall + EIP-7702 — chains of calls execute atomically, as one signature, or not at all.

Try it live

Compose a batch, sign once

WAASDK doesn't swap or stake tokens — it batches and sponsors the calls around them. This is the real mechanism: pick an action, watch the batch it builds, sign it in one transaction.

Roadmap

Where this actually stands

SHIPPED

Core SDK — session keys, Permit2, ERC-2612, multicall

48/48 unit tests passing. Built on Sequence's deployed contract stack.

SHIPPED

Backend platform — auth, projects, analytics, relay

Fastify + MongoDB, live and responding.

IN PROGRESS

Custom domain + production hardening

Moving off the bare IP, wiring up real project keys end-to-end.

PLANNED

Expanded chain support & console self-serve project creation
