Self-custodial by default
Your keys never leave your device. We can’t move your funds, freeze them, or see them — not because we promise not to, but because the architecture gives us no way in.
// engineering studio · self-custodial crypto
Crypto software you don't
have to trust.
Monday Labs builds open-source, self-custodial wallets and infrastructure — the kind you can verify yourself. Every line of code public, every key on your own device, nothing left to take on faith.
// how we build
Principles we don't bend.
Security software earns trust by being checkable, not by sounding confident. These four rules shape everything we ship.
Open source, end to end
The app and every service behind it are public. You don’t have to trust a pitch — you can read the code, build it yourself, and run it on your own machine.
Verifiable, not promised
Audited contracts, on-chain accounts, and standards anyone can check. We lead with proof — independent audits and public infrastructure — instead of marketing claims.
Minimal on purpose
Every extra feature is more code to trust and more surface to attack. We ship less, keep the attack surface small, and harden what’s left.
// our flagship
Vela Wallet
LiveYour keys. Your face.
A self-custodial wallet for ETH and ERC-20 tokens. You hold and move assets with a passkey stored on your device — the private key never leaves it, and Monday Labs never touches it. We can’t access your keys. Not “we promise not to” — we architecturally can’t.
Passkey signing
Sign with Face ID or Touch ID. WebAuthn / P-256 — no seed phrase, no hardware key.
One address, every chain
The same account across 12 EVM networks, from Ethereum and Base to Arbitrum and Polygon.
Audited foundations
Built on unmodified Safe v1.4.1 smart accounts and an independently audited WebAuthn signer.
Self-hostable
Bundler, backend, and web app can all run on your own infrastructure. No vendor lock-in.
12 EVM chains
0 Seed phrases
100% Open source
1 Address everywhere

// about
A small team building the tools we wanted to use.
Monday Labs is an independent engineering studio working on self-custodial crypto. We got tired of choosing between wallets that were easy but custodial and wallets that were secure but punishing — so we set out to build software that is both, and that holds up to scrutiny.
We build in the open. Our infrastructure is designed so that nothing critical depends on us staying online or staying in business: the code is public, the accounts live on-chain, and everything we run can be self-hosted. If Monday Labs disappeared tomorrow, your wallet would keep working.
Build on solid ground.
