Pattern

regexJavaScript
/\b(?:[13][a-km-zA-HJ-NP-Z1-9]{25,34}|bc1[a-zA-HJ-NP-Z0-9]{25,62})\b/g

Raw source: \b(?:[13][a-km-zA-HJ-NP-Z1-9]{25,34}|bc1[a-zA-HJ-NP-Z0-9]{25,62})\b

How it works

Legacy addresses start with 1 or 3 followed by 25–34 Base58 characters (no 0, O, I, l). Bech32 SegWit addresses start with bc1 followed by 25–62 chars from its restricted alphabet.
