Three steps to your
sonic identity
Pick your sound
Choose any audio clip — record your own, or browse thousands of free sounds online. Make it something that feels like you.
Mint your signature
We create a unique digital fingerprint of your sound, bound to your wallet address. No one else can own the same combination.
Play it on payments
Every time you confirm a transaction in the app, your sonic signature plays as the confirmation sound. Not a generic beep — your sound, your signature.
Not just an NFT.
An identity.
One of a kind
Your fingerprint is derived from your sound and your wallet address combined. Two people using the same audio file will always get a completely different result.
Non-transferable
Soulbound — cannot be sold, transferred, or stolen. It is bound to your wallet for as long as you choose to keep it.
Decentralised
Your audio lives on IPFS and the Base blockchain. No company, no server, nothing between you and your sound.
Swappable
Changed your mind? Burn your current signature to free your slot, then mint a new one with a different sound. Your identity, on your terms.
No accounts. No custody. Your wallet, your sound, your rules.
The contract is open source and verified on-chain.
