Your address.
Your proof.
Provably yours.
The link in bio for crypto. Every address is cryptographically signed, so your audience can prove it’s really you. Impersonators can’t fake it.

✓Not built for everyone. Built for people who get impersonated.
If you’ve ever posted a wallet address in public, someone has tried to swap it in your replies. Bitsy is the one page they can’t fake.
Creators & streamers
Your tip address, on screen and in every bio, signed so it’s provably yours. The scammer dropping a fake address in your chat loses every time.
Traders & treasuries
OTC, P2P, payouts. Counterparties verify the address before they send, with no “are you sure this is really you?” back and forth.
Projects & DAOs
One signed donation address your whole community can check. The impersonation drains that hit every launch stop at the signature.
Anyone holding their own keys
Hardware wallet, mobile, multisig. One clean page for every asset and network you accept. No custody, no tracking, nothing to trust.
Every badge is checkable by anyone.
No account. No trust in Bitsy. Paste a signature into any standard tool, or use ours, and watch the math confirm the owner. The proof lives on the page, not in our promise.
Verify any profile →Trust signals an ordinary link page can’t carry.
Anyone can paste an address into a bio. Bitsy is built so the people sending to you don’t have to take it on faith.
Ownership verified
Sign a one-time message with your wallet to earn a badge visitors can re-check themselves.
Your whole profile, signed
One signature seals every visible address. Any change retires it, and visitors verify without trusting Bitsy.
History that can’t be rewritten
Hash-linked signatures, anchored in Bitcoin. The record of every address is tamper-evident.
Check before you send
One paste confirms the address in your wallet matches this page, catching clipboard malware cold.
Non-custodial by design
Bitsy never holds your keys or funds. It only shares the public addresses you choose to display.
Watch any profile
Repeat senders get one email if the addresses ever change. Ongoing assurance, double opt-in.
