Any wallet can create multiple independent locks by pasting a mint address, choosing a positive amount, and setting an unlock date. Tokens move into a PDA-owned associated token vault. Only the original depositor can claim, and only after unlock_at. Claim closes the vault and the lock PDA so rent returns to the depositor.

Program

• Program ID: 9RY54dNPYTzDyh3TfFqDdt2b2KMM56KW1tw9erRTGQo6
• Keypair: target/deploy/fridge-keypair.json
• PDA seeds: ["lock", depositor, mint, lock_id_le_bytes]
• Token program: Token-2022 only (TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb)

Stored lock fields: depositor, mint, amount, created_at, unlock_at, bump, plus lock_id so each lock stays unique and claimable.

create_lock rejects zero amounts, past unlock times, wrong mint/ATA/authority, and non-Token-2022 mints. Transfers use transfer_checked. The amount stored is the vault balance after the deposit (so transfer-fee mints record what actually arrived).

Redeeming takes a 2% fee that buys and burns $PASTA (39kMeX4HVRW9qbbiHSPbRQ9xeXUF18GrNP6gL61Ppump):

• If the lock is PASTA, the program burns 2% from the vault.
• If the lock is another Token-2022, the program swaps 2% to PASTA through Jupiter and burns the output.

Frontend

Phantom wallet adapter, mint lookup, amount + date presets, lock list, and claim.

cd app
npm install
npm run dev

Open http://localhost:5173

Deploy

Requires Solana CLI + Anchor 0.30.1.

solana config set --url devnet
anchor build
anchor deploy --program-keypair target/deploy/fridge-keypair.json

Then set the program ID in the dApp Program & RPC panel. Use a private RPC if lock listing fails (getProgramAccounts is often blocked on public endpoints).

Tests

cargo test --manifest-path programs/fridge/Cargo.toml --lib
cd app && npm test
cd ../scan && npm run build
cd ../bot && npm run typecheck

GitHub Actions runs program tests, scanner and app builds, app unit tests, and bot type-checking for every pull request. See SECURITY.md for the current audit status and vulnerability reporting process.
