Protocol to product
Blockchain / Crypto
Smart contracts, indexing, wallets, and the full-stack product around a protocol. I have been in this space long enough to care more about correctness and UX than slogans.
Discuss this workThe usual failure
Crypto products fail in the seams: a contract that cannot be operated, an indexer that lies, a wallet flow users abandon, or a backend that treats the chain as an afterthought.
How I take it
I treat the chain as one constrained datastore with public consequences. Contracts, indexers, APIs, and UI get designed as one system — with threat models, upgrade paths, and the unglamorous operational work included.
What you leave with
▸Contracts and integrations that match how the product is actually used
▸Indexing and read paths that stay honest under load
▸Wallet and transaction UX that does not leak complexity
▸Clear security and upgrade boundaries
Typical engagements
▸Protocol / dapp architecture
▸Smart contract integration
▸Indexing and backend design
▸Wallet, key, and transaction flows
Other lanes
If the work is real, I will take it.
Pactum is a one-person practice. You work with Matthew Swezey — not a bench that gets swapped after the pitch.
