Bech32 Laravel Package

Product Decisions This Supports

• Feature enablement: Bitcoin/crypto wallet functionality — generating and validating native SegWit (bech32) addresses, encoding/decoding BIP-173 strings, and producing QR/invoice payloads for a Laravel app.
• Build vs. buy: Strong case for buy (or vendor) over build. Bech32 requires a checksum algorithm (BCH codes) and HRP handling that is easy to get subtly wrong; a small, permissively licensed library removes that risk from the critical path.
• Roadmap input: Relevant only if crypto payments, custody, tipping, or address-book features are on the roadmap. If the product stays fiat-only, this is not a dependency worth carrying.
• Use cases to scope: validating a user-pasted BTC address before a withdrawal, deriving display addresses for deposits, and normalizing mixed-case addresses for storage.
• Risk gating: Its maturity signals (README-only, 12 stars, 0 dependents, EOL PHP targets, Travis CI) should trigger a vendor-review decision before it lands in a payment-critical path.

When to Consider This Package

Adopt when:

• You are building on an existing Bit-Wasp/Bitcoin PHP stack (this package is explicitly positioned as a transitional shim for legacy codebases).
• Your runtime is PHP 5.6–7.2 and you cannot yet move off it.
• You need a pure-PHP, extension-free encoder with no Composer dependency tree — attractive for constrained or audited deployments.
• Licensing matters: Unlicense is effectively public domain, so no attribution or copyleft obligations.

Look elsewhere when:

• You run PHP 8.x / Laravel 9+. The README caps support at 7.2, which is end-of-life; expect compatibility friction and no upstream fixes.
• You need bech32m / Taproot support — not mentioned in the README.
• You require active maintenance, security patching, or a CVE response path. Zero dependents and README-level maturity mean no community backstop.
• You need audited or widely adopted crypto primitives; consider bitwasp/bitcoin itself or a maintained alternative, and wrap whichever you choose behind an internal AddressCodec interface.

How to Pitch It (Stakeholders)

For executives: This is a tiny, public-domain-licensed utility that lets us handle modern Bitcoin addresses without writing cryptographic checksum code ourselves. Cost is near zero and it removes a class of "we shipped a wrong address" bugs. The trade-off is maintenance risk: the project is small, lightly used, and targets older PHP versions, so I'd recommend it only as a wrapped, pinned dependency — not as a long-term platform commitment. Decision needed: is crypto address support on the roadmap at all?

For engineering: Pure PHP, no extensions, deterministic bech32 encode/decode plus SegWit address formatting. Two caveats: (1) it supports PHP 5.6–7.2 only, so PHP 8 compatibility is on us; (2) it is a transitional shim intended to be absorbed into bitwasp/bitcoin. Proposal: wrap it behind an internal codec interface with our own tests against BIP-173 vectors, pin the version, and revisit if we move to PHP 8 or need bech32m.
