Dogecoin Address

Detects Dogecoin mainnet addresses: Base58Check encoded, 34 characters long. Pay-to-Public-Key-Hash (P2PKH) addresses use version byte 0x1E and start with "D"; Pay-to-Script-Hash (P2SH) addresses use version byte 0x16 (22) and start with "A" (leading "9" is also possible for that version byte). A single leading letter is weak structure, so detection is context-gated. Prefix/version/length verified against libdogecoin and Dogecoin address-type docs.

Type: regex
Engine: universal
Confidence: medium
Confidence justification: Gated 75, not high: a single leading D/A/9 plus a base58 run is weak structure with no regex-expressible checksum, so it collides with other similarly-prefixed base58 tokens (notably other coins' base58 addresses). Precision comes from the mandatory cryptocurrency/wallet domain-context gate plus the noise exclusion.

Should match

DGZpfEKqPEwQqtbfpNLk5pu8E3gq5PwNgK — P2PKH address (D prefix) from libdogecoin address docs (34 chars)
D7Y55hsu3uvxyXoPjHojmV2hj92bxkD6Ue — P2PKH address (D prefix), documented example (34 chars)
A9Lbq5HbUpK8P3hP2ZoWbEv1k2Nh1Q9bD4 — P2SH address (A prefix, version byte 0x16), documented example (34 chars)

Should not match

1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa — Bitcoin legacy address — wrong prefix (starts 1, not D/A/9)
D7Y55hsu3uv — Too short (below the base58 body minimum)
D7Y55hsu3uvxyXoPjHojmV2hj92bxkD6UeXY — Too long (D + 35 = 36, above the 34/35 envelope)
D7Y55hsu3uvxyXoPjHojmV2-hj92bxkD6Ue — Hyphen breaks the run so no contiguous body exists — rejected
dogecoin wallet address example placeholder — Template/placeholder context should be excluded even when domain anchor words are present

Known false positives

A single leading D/A/9 plus a base58 run collides with other coins' base58 addresses (Dogecoin and Litecoin/Bitcoin share the same base58 alphabet and 34-char envelope) and with arbitrary base58 tokens; the Base58Check checksum cannot be validated in a Purview-safe regex. Mitigation: The tier is AND-gated by cryptocurrency/wallet domain context (crypto-wallet-context) within the proximity window plus a template/sample noise NOT-group; held at 75. Co-fire with other coins' SITs on the shared base58 envelope is expected and corroborating, not conflicting.
