Self-custody with time to react

Crypto should not move at the speed of panic.

Slowlyy is a self-custody wallet built around deliberate delay. Outgoing transfers do not leave instantly, which gives you time to catch theft, coercion, and expensive mistakes before they become final.

Why slowly? Most self-custody products optimize for speed. Slowlyy treats time as part of security.

Withdrawal timeline

A transfer should have a cooling period.

Request 0.42 BTC

Destination bc1q...9x4m

Current state Pending release

Step 01 Request initiated

The transfer is submitted, signed, and logged.

Step 02 Cooling period

Time exists for review, cancellation, and recovery if something looks wrong.

Step 03 Final release

Funds move only after the delay has completed.

Self-custody fails fast.

In most wallets, the worst moment is also the fastest one. If a phone is stolen, malware gets access, or a tired user approves the wrong transfer, funds can disappear in minutes. Passwords and 2FA help, but they do not change the fact that irreversible money movement happens too quickly.

Slowlyy adds time to the threat model.

Instead of treating speed as a feature, Slowlyy treats it as a risk. Outgoing transactions wait before release. That waiting period creates room to review, to notice something suspicious, and to stop damage before it becomes permanent.

Product state

The live product today is built to demonstrate the withdrawal model clearly. Mainnet is being shaped around the same principle, with longer configurable delays and stronger hardening.

Live now

Testnet

30 minute transfer delay so the core idea is visible immediately.
Uses testnet funds only, with no real value at risk.
Best way to understand the product flow before mainnet exists.
Seed phrase is shown once and should be stored offline as a recovery fallback.

In development

Mainnet

Configurable 3 to 30 day delay for materially stronger protection.
Planned support for Bitcoin, Ethereum, BNB, and Cardano, with more to follow.
Security hardening, cancellation logic, and recovery-oriented UX are still in progress.
The goal is not just custody, but time to respond when something goes wrong.

Why delay matters

A thief who gets your device should not get your funds in the same hour.
Self-custody remains intact: users still hold their own keys.
The waiting period gives space to review destination addresses and catch mistakes.
Suspicious outgoing transfers can be noticed before they settle.
Security is not only cryptography. It is also the time available to react.

A payment can be pending and still be real.

Slowlyy introduces a state between “not sent” and “fully settled.” A transfer can be initiated, verifiable, and scheduled before it becomes irreversible on-chain.

Signed pending receipt

Proof before finality

The payment exists and has entered its waiting period.
The funds were available when the transfer was initiated.
The recipient gets structured confidence before final settlement.

Auto-settles unless vetoed

Scheduled release logic

The transfer remains vetoable during the waiting window.
If no veto occurs, the payment is released automatically when the delay completes.
A signed pending receipt is not final settlement, but it is more than an informal promise.
