Passkey wallet · API bots · fee-checked relays

Your wallet. Your signature. Your bot.

A cross-device passkey wallet, an API-key bot builder and smart-contract relays that accept only the order you sign. Built for fast markets across the supported Ethereum, Base, Solana and Monad surfaces, with no platform-held Wallet-owner key.

The programmatic API is rolling out; value-moving paths open only after the documented safety and release criteria are met.

Ethereum · Base · Solana · Monad · Bitcoin — supported

The wallet, bot configuration and execution boundary stay separate: you control the key, the bot carries a bounded authorization and the relay checks the fee before submission. Market and venue selection is based on measured activity, not a promise of returns.

01 · The control layer

One path from a passkey to a verified receipt.

The product is centered on the part fast-market users cannot outsource safely: the signing boundary. Memecoin and social surfaces remain available, but the core workflow is the wallet, the bot and the relay.

Cross-device walletPasskey-controlled signing without a platform-held owner key.
Open the same wallet on another enrolled device. The signing key is derived only after the owner's passkey ceremony and is not handed to the API or relay.
API bot builderStructured reads, bounded orders and receipts.
Build the bot around the same authorization model as the app. Keys authenticate the bot, while the order still carries the owner's wallet, amount, output floor, gas and expiry constraints.
Fee-checked relaySmart-contract execution with a visible fee leg.
The relay cannot widen the signed order or remove the fee. Supported EVM and Solana routes reject malformed, expired or fee-free payloads before broadcast.
02 · The moat

Three structural costs LOSURIA is designed to remove.

One risk per row, one implemented control per row. Runtime measurements are published at /latency.

Public-mempool exposureA publicly broadcast pending swap can expose its calldata before inclusion.
Supported Ethereum swap and snipe submissions use private relay execution without a public-RPC fallback. The same signed transaction is submitted through the protected execution path; if the supported path rejects it, LOSURIA fails closed instead of broadcasting it publicly. Selected Solana, manual Monad and Bitcoin modes use the endpoint identified in the app. Automated Monad sniping uses an owner-signed order through the backend relay path.
RPC latency & rate limitsRemote endpoint latency and throttling can delay detection, quoting and submission.
The Ethereum quote path uses dedicated execution infrastructure — no public-RPC fallback on the supported path. Live p50/p95/p99, measured, at /latency.
Custodial freeze riskA platform-held owner key makes access to the wallet depend on that platform.
Your wallet is protected by your passkey. A random master seed is wrapped under private WebAuthn-PRF output; the signing key is derived in-browser only after a fresh ceremony, used for one operation and then dropped. We store PRF-encrypted ciphertext, never the plaintext Wallet owner key.
Single-device lock-inA device-bound wallet needs a deliberate recovery and device-enrolment path.
Your wallet survives device and passkey changes. A synced passkey can open its enrolled envelope; another PRF-capable passkey can be enrolled through the authenticated pairing or renewal flow. Once enrolled, it decrypts the same master seed and therefore preserves the wallet's EVM, Solana and Bitcoin addresses. An independent secret export remains the final recovery path.
03 · Subscription

Start with the control layer.

Pro gives you the cross-device passkey wallet, API key and bot-building surface, plus owner-signed low-latency execution. Whale adds the signed programmatic order and fee-checked relay routes, with higher grids and Intelligence limits.

The API key and bot builder are available from Pro. Value-moving programmatic relay routes remain subject to the documented tier, owner signature, fee check and safety gates.

Price fixed in EUR, paid directly in DAI from your own wallet. No deposit, no KYC documents for standard wallet access; lawful abuse or sanctions controls may still apply.

04 · On-chain proof

Live on mainnet, today.

Core contracts are deployed with a public verification status for each address; Sourcify exact_match is the byte-for-byte source proof where it is available. The fee-flow path is immutable: no admin function can redirect collected funds or change the sink. Each address links to its verification record.
