SEAM
A wallet for people banks leave out.
SEAM is a digital wallet and community fund aimed at people the financial system excludes — currently a pre-launch preview I built and published: a thesis site, a 39-screen bilingual wallet demo, and a public ledger sharing one seeded dataset with its transaction explorer, so the two views can never disagree. Every screen that could be mistaken for a working service says on its face that it is not one.
Translation is treated as a legal surface, not a cosmetic one. A load-bearing Spanish glossary keeps the community fund a recoverable grant rather than a loan — the wrong verb would change what the product is. I audited 734 pairs for loan-language drift and shipped a help screen disclosing what has not yet been reviewed by a native speaker.
The deploy path is a safety boundary, because the repo sits beside a personal tool containing real bank transactions. Publishing copies a named allow-list into a clean temporary root and aborts if bank-data markers appear — an allow-list cannot silently grow to include a file; an exclude-list can.
The strategy is written to be falsified, not pitched: an adversarial bear case, a graveyard analysis of eleven dead companies, and one threshold that now governs the model — revenue per account per year, where nothing below $50 survived and nothing above $150 failed. A freelancer tax-withholding product remains the retained US-side wedge; the wallet is the thesis it serves.
