Programmable on-chain inheritance · Solana · PUSD

Quiesce. The protocol for
what comes after.

A vault owner deposits PUSD and commits to a heartbeat — a check-in cadence. While they keep checking in, the vault is dormant. If they stop, anyone can release the full balance to the named beneficiary on the next confirmed block. Quiesce holds no keys and cannot intervene.

How it works

Four steps. The owner sets terms, keeps checking in, then — either by their own choice or by missing a check-in — the vault settles. Each transition is on-chain, witnessable, and final.

01
Set up the vault.

Owner deposits PUSD, names a beneficiary, and configures a heartbeat — a check-in cadence they commit to.

02
Check in to keep it dormant.

While the owner heartbeats on schedule, the vault is theirs. They can cancel any time and recover the funds.

03
Heartbeat expires.

If they stop checking in, the trigger window opens. The owner can no longer cancel.

04
Anyone releases the funds.

A permissionless claim transfers the full balance atomically to the named beneficiary. Quiesce holds no keys and cannot intervene.

Why PUSD specifically

Most stablecoins — USDC, USDT — ship with a freeze authority. The issuer can disable a token account at will. That capability defeats the point of an inheritance protocol: a bequest must execute when its conditions are met, regardless of jurisdiction, sanctions exposure, or institutional pressure.

PUSD has no freeze function, no blacklist, no pause mechanism. Once issued, the tokens are governed entirely by the on-chain logic that holds them. That is what makes Quiesce's settlement guarantee a property of the protocol, not a marketing claim.

Built for inheritance that has to work

Inheritance carries religious weight in Islamic finance — wasiyyah is a core obligation, and the $3T Islamic finance market has no native digital inheritance infrastructure. PUSD is the first major Shariah-compliant stablecoin. Quiesce fits that market structurally.

It is not only for Islamic finance. Crypto-native families, executors, and anyone with assets to bequeath under conditional logic can use the same protocol on the same terms.
