A memory now. A Smile Fund for later.

A fallen-tooth memory becomes two connected things: a private time capsule for the artwork and family messages, and an optional Smile Fund for opening day.

It is a small program on Solana. It records the time-lock and opening date, applies the disclosed 2% deposit fee, protects the remaining 98%, and controls when deposited funds can be released. It reduces reliance on TFN, but it is not literally a regulated bank account and still carries software, wallet, and network risk.

Solana makes the date and funding receipts independently verifiable while keeping transaction costs small. The live Vault accepts SOL. TFN has also completed the SOL and USDC lifecycle on Devnet; USDC becomes a live Mainnet choice after its multisig security release and canary.

The artwork, child’s words, guardian note, email, and owner controls stay behind the private Vault link. Only the cNFT receipt, wallet addresses, funding amount, and opening date are public on Solana.

No. A familiar account can be restored through TFN and Coinbase can provide the purchase handoff. Crypto-native adults can instead use a compatible Solana wallet. Every contribution still requires the adult’s explicit approval.

The family returns through the private Vault. The time capsule can be opened and the authorized guardian can approve release of the Smile Fund under the smart-contract rules.

The adult-controlled wallet owns the public Toothlight cNFT. Deposited SOL or USDC stays in the smart-contract Vault under the recorded guardian, recipient, and opening-day rules. Ownership of the cNFT does not reveal or transfer the private message.
