A Solana wallet and toolbox monorepo providing web extension, web app, and API for managing accounts, signing, and dapp connections

A shipped, tested Solana wallet stack that already won Cypherpunk in a crowded niche.

Verdict

Samui Wallet is a real Solana wallet toolbox: browser extension, web app, and a Cloudflare Workers API sharing @solana/kit and wallet-standard primitives, backed by vitest unit tests and Playwright e2e specs covering onboarding and token flows Samui Wallet qualitySignals: vitest, Playwright, CI, monorepo structure. It surfaces in the corpus as its own entry and its README documents a Cypherpunk hackathon win, giving it rare direct winner evidence rather than a mere pattern-match Self-match: scanned project is corpus entry (samui-wallet); README claims Cypherpunk win. Momentum is strong: 822 commits from 23 contributors over ten months, 170 stars, and pushes as recent as July 2026 GitHub metadata: 822 commits, 23 contributors, 170 stars, pushed 2026-07-05. The niche isn't empty, though: the engine reports 257 topical neighbors, and winners like Lazor Kit (Honorable Mention, Infrastructure, sim 0.088) and Solana Developer Wallet (sim 0.079) chase the same onboarding/wallet-infra wedge . Ecosystem fit is excellent given genuine on-chain-facing primitives (signing, vault, network switching) and docs/i18n polish matching what winning infra projects ship. The weakest link is originality: the toolbox differentiates through breadth rather than a novel primitive. Next move: sharpen a single distinguishing wedge, such as invisible-wallet onboarding, to convert breadth into a signature feature.

Winner DNA

  • Solana-native tech stack (react/typescript, @solana/kit): present

    Repo uses @solana/kit, wallet-standard, and SPL token packages matching the 99.4% solana-tag share among winners.

  • Wallet primitive present in winning cohort: present

    Wallet appears in 7.4% of cohort winners (e.g. armor-wallet, paytos); this repo's core is wallet infrastructure.

  • Onboarding-friction reduction focus: present

    Sign-in/onboarding and account bookmarking flows mirror the onboarding-friction problem tag seen in winners like Lazor Kit.

  • On-chain Rust/Anchor program: missing

    Cohort shows 34.7% Rust and 20.5% Anchor usage, but this repo is a client-side wallet/API stack with no on-chain program.

  • Verified hackathon win/placement: present

    README documents a Cypherpunk hackathon win, and the project is a corpus entry itself (self-match excluded).

  • Mobile/React Native presence: missing

    Only 4.5% of winners ship React Native, and this repo has no mobile app, only extension/web/API.
