How Magnet works

From zero to on-chain
in four API calls.

Wallet creation, signing, broadcasting, and event delivery — without running any of it yourself.

Create a wallet in one call

POST a chain, network, and policy. We generate an HD wallet, encrypt the seed per-tenant, and hand you back a wallet ID.

Generate addresses on demand

Derive fresh receive addresses on any supported chain — SegWit, Taproot, EVM. We store the derivation path so you don't have to.

Sign with a passkey

End users approve transactions with Face ID, Touch ID, or a security key. No seed phrases, no extension, no phishable secret.

Wallet as a Service

Programmatic wallets, signed your way.

Generate hierarchical deterministic wallets, manage permissions, and sign transactions with passkeys, multi-sig, or API keys. Tenant-scoped encryption keeps keys isolated by default.

BIP39 / 44 / 49 / 84 / 86 support
Full HD derivation, SegWit and Taproot, on every chain we support.
Passkey & WebAuthn signing
Hardware-backed approval flows — no seed phrases for your end users.
Tenant-scoped encryption
Per-tenant keys, audited permission checks on every wallet operation.

“We replaced an in-house custody stack with Magnet in a weekend. The passkey flow alone saved us six months of WebAuthn work.”

Sara Chen

CTO, Vault Labs

“Their indexing endpoints are stupid fast. We dropped TheGraph and a Postgres replica and our p95 went from 2s to 90ms.”

Marc Delgado

Eng Lead, Helix Pay

“We process eight figures per month through Magnet webhooks. Zero missed events in a year. That's what we pay for.”

Priya Natarajan

VP Engineering, Layer FX

FAQ

Answers, before you ask.

Keys are encrypted with per-tenant master keys, stored in an HSM-backed vault. We never see plaintext keys, and a key compromise in one tenant cannot be used to derive another tenant's keys.

No. Magnet runs the nodes, the indexers, and the webhook delivery layer. You hit our API. We give you SLA-backed responses, regional replicas, and auto-failover for every chain.

Ethereum (mainnet, sepolia), Polygon (mainnet, amoy), BSC (mainnet, testnet), and XRP Ledger (mainnet, testnet, devnet). Solana, Avalanche, Arbitrum, Optimism, and Base are on the roadmap.

End users register a WebAuthn passkey (Face ID, Touch ID, security key) tied to their account. Every transaction requires a hardware-backed approval — no seed phrase, no extension, no phishable secret.

Scale plans are bespoke. We size based on wallet count, transaction volume, and the chains you need. Most production customers land between $1,500 and $20,000 / month. Talk to sales for a quote.

Yes — Scale plans include a self-host option deployed via Helm into your AWS / GCP / Azure account. We manage the control plane; the data plane runs in your VPC.
