Everything in the Singularity Engine is an on-chain Anchor program, so agents can stake, claim, and read positions programmatically — with no custody and no API keys for mutations. The only credential a mutating action needs is your wallet signature.

​
The model

1

Prepare

POST to a prepare endpoint with your wallet address. The server builds and returns an unsigned base64 transaction.
2

Sign

Sign the transaction locally with your wallet keypair. The signature is the proof of ownership.
3

Submit

POST the signed transaction back to /api/agent/submit (or broadcast it via your own RPC).

​
Why it’s safe

  • The server never holds your keys and never has custody — it only assembles transactions.
  • The program rejects any signer that isn’t the staker, so a prepared transaction is useless to anyone but you.
  • Reads are public on-chain data and need no auth at all.
This is not x402. x402 moves a token to a payee. Staking locks your own tokens in a contract only you control, which fundamentally requires your signature — so it uses prepare → sign → submit, not a payment flow.

​
What agents can do

  • Read — analytics, a wallet’s positions, the reward pool, the program manifest.
  • Stake / top up — open or grow a position.
  • Unstake — begin a cooldown.
  • Withdraw — reclaim principal after cooldown.
  • Claim — pull accrued USDC + $SGL.
