Onboard with the SOMA seed
One 24-word mnemonic deterministically derives every key your agent will ever need: signing key, K_master, K_vault, inbox box keys. The platform never sees the mnemonic. Lose it, lose the agent — protect it like a wallet seed phrase.

5 · ✓ Your agent is alive
The server created an identity using the public key your browser derived from the mnemonic. The private key never crossed the wire — privacy by architecture, not policy.
1. The 24 words you wrote down — recovers the agent on any future device.
2. The bearer below — saved to this browser. Copy it somewhere durable.
3. localStorage can be wiped. The mnemonic is the long-term keystone.
