Questions

Three ways out

Pay your own addresses instantly.

Your exchange, your bank off-ramp, your cold wallet. Adding a new one waits days, or needs your guardian.

Create a vault. An account on the chain that only your wallet controls. Ecrin never touches your keys.
Pick your protection. Gentle, Strong or Locked; add trusted addresses and, if you like, a guardian.
Live normally. Pay your own accounts instantly. Everything else waits, and you can always change your mind.

Every coin. Every chain.

One vault per network, the same rules everywhere. USDC sits next to your SOL, ETH or POL, with its own daily limit.

A bad day, with Ecrin

The attack works. The money stays.

Before

All quiet.

Your savings sit in the vault. Your own trusted addresses can be paid instantly; everything else has to wait.

0:00

Your key leaks.

A thief signs a withdrawal of everything to their own address. On a normal wallet, this is the end of the story. Here, Solana itself queues it for your delay, and it shows up with a countdown.

0:20

You press Cancel.

Free and instant. Then you get out on your terms: pay your own trusted address, or request a withdrawal to a fresh wallet and have your guardian release it on the spot.

72:00

Nothing was taken.

The thief can't shorten the delay, add their address as trusted, or name their own guardian without waiting days. A key can make the rules stricter, never looser: at worst it freezes the vault, it never empties it.

Every shortcut we know of, and why it fails

Way around it	Why it fails
Import your key into another wallet	The key can only request a withdrawal. The program still enforces the wait.
Turn the rules off	Loosening any rule waits days, and never before a lock ends.
Add the attacker's address as trusted	New trusted addresses wait days, or need your guardian's approval.
Name a second wallet as guardian	Any guardian change waits days, so no one can approve their own withdrawal.
Sell a receipt token for instant SOL	Unlike liquid staking, there is no token to sell.
The developer changes the code	The program will be made immutable after its audit.

A hardware wallet protects your key. Ecrin protects your money.

They work best together: sign for your vault with a hardware wallet, and both have to fail before you lose anything.

FAQ

Questions, answered.

Is my money safe? Who holds it?

Your funds sit in a program account on Solana tied to your wallet. Ecrin never has your keys and can't move your funds. Only your wallet can request a withdrawal, and only the program's rules decide when it can run.

What if someone steals my key?

They can only ask to withdraw, and that waits your full delay, so cancel each request before it runs (Telegram and email alerts tell you within a minute). To move out, pay one of your trusted addresses, or request a withdrawal to a fresh wallet and have your guardian release it at once. A stolen key can make your rules stricter but never looser: it can't add its own trusted address, shorten a delay or name a guardian without waiting days, so at worst your funds are frozen, not taken. That's why we recommend a guardian on Strong.

What if I have a real emergency?

Your guardian can co-sign a withdrawal you already requested so it runs immediately. They can't start one, change the amount or pick where it goes. You can also always pay your trusted addresses instantly.

Can my guardian take my money?

No. A guardian can only approve something you asked for: an emergency release of your own withdrawal, or a trusted address you proposed.

Will I be able to earn yield?

That's the plan: native SOL staking where the stake stays inside the vault, so you earn rewards without creating a fast way out. It comes after the audit.

What can I store?

During the beta: SOL and USDC on Solana devnet, and ETH (POL on Polygon) and USDC on Ethereum Sepolia, Base, Arbitrum, Optimism and Polygon test networks. Each coin has its own balance and daily limit under the same rules.

Does it cost anything?

The devnet beta is free, using test coins. You only pay normal network fees, a fraction of a cent.

Is it live on mainnet?

Not yet. Ecrin runs on test networks while it's being tested. Mainnet comes after an independent security audit, with deposit caps at first.

Why "Ecrin"?

An écrin is the case that keeps something precious safe. That's the whole idea.

Your savings, out of reach of anyone in a hurry.
