Session keys, EIP-7702 batching, and sponsored transactions via Permit2 and ERC-2612 — non-custodial, multi-chain, orchestrated through a staged smart-contract pipeline.
Session keys scoped to specific contracts and time windows — the platform never holds user keys.
CREATE2 singleton deployment — the same wallet address on Ethereum, Base, Arbitrum, and beyond.
Permit2 and ERC-2612 approvals signed off-chain, executed by a sponsor wallet — zero native gas required.
Multicall + EIP-7702 — chains of calls execute atomically, as one signature, or not at all.
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.
48/48 unit tests passing. Built on Sequence's deployed contract stack.
Fastify + MongoDB, live and responding.
Moving off the bare IP, wiring up real project keys end-to-end.
