Your keys. Your exit. Always.
Arca is the self-custodial account layer behind apps like Gobi. You hold a key Arca can't take away — if Arca ever goes dark, you withdraw your funds yourself, with no server or signature from us.
Built for self-custody
Your funds stay yours, the numbers stay honest, and the proof is continuous.
Self-custody by default
Your funds live in your own on-chain account. Arca operates it within on-chain limits — it can never just take them.
Live balances
Balances and operation events stream in real time, so what you see is always what is on-chain.
Every dollar accounted for
Every balance is double-entry and provable — nothing is silently edited, and the numbers reconcile continuously.
How self-custody works
You are always the one in control. Arca is the account layer; the apps just help you use it.
You hold the key
Every account has a recovery key that only you control. Arca never holds it and can never take it away.
Arca is the account layer
Your funds sit in your own on-chain account. Arca operates it within on-chain limits — it can route your trades, but it works for you, not the other way around.
Apps build on top
Gobi and other apps are front-ends to your account, all using the same public API. Switch apps anytime — your funds and your key stay yours.
If Arca ever goes dark, you withdraw your funds yourself — no Arca server, no signature from us. That is what makes it self-custody.
Apps built on Arca
Self-custody apps, built on the same account layer — starting with our own.
Gobi
A self-custody trading app. Trade perpetuals on-chain while you hold your own keys.
hellogobi.comAnd the next ones
More first-party apps are on the way — and the same public API is open to outside builders. Every app, including ours, uses it: no backdoors, no special access, the same self-custody guarantees for every user.
The Explorer
Every balance, event, and operation — visible and provable in real time.
Guarantees, not promises
Self-custody is only real if it is structural. These are enforced on-chain and in the ledger — not promised in a policy.
Built on proven experience
Arca brings together deep expertise spanning search-scale infrastructure, crypto-native protocols, consumer distribution, and capital markets.
