Private inference for onchain agents.
Every model runs inside a hardware enclave. Pay per call in USDC, USDT or PYUSD on Solana. No accounts.
USDCCircle's dollar, SPL token on Solana
USDTTether on Solana
PYUSDPayPal USD on Solana, Token-2022
Your prompts stay out of everyone else's logs.
Models run in an enclave
Inference happens inside an Intel TDX machine with a confidential NVIDIA GPU. The host operator cannot read prompts or outputs.
Every response is signed
Each call returns a receipt signed by the attested enclave, with a link to the public attestation report so you can check it yourself.
Nothing is cached or stored
We keep token counts for billing. We do not keep prompts, outputs or upstream error bodies.
Open models, served privately.
Prices are per million tokens, charged to the exact token. The list below is read live from the gateway.
Use it like any OpenAI endpoint.
Fund a key from your wallet
Sign in with Phantom, Solflare or Backpack, deposit from one dollar, and get a prepaid key. Close it any time and the balance is sent back.
Point your SDK at Sealane
Change the base URL and the key. Streaming responses work the way your code already expects.
Or let the agent pay per call
With no key at all, the gateway answers 402 with a price. An x402 client signs it and the call goes through.

Pay for what you use, where you hold funds.
The same price is quoted in every stablecoin. Your agent pays with whichever one its Solana wallet already holds.
No account
A wallet is the only identity. There is no email, no card and no approval step between an agent and its first call.
A prepaid key is charged the real token count. The worst case is held first, so a key can never overrun its balance.
Pay per call signs a ceiling. Whatever the call did not use is sent back to the payer, in the same token, on Solana.
An SPL token on Solana. Holders pay less: each tier takes a percentage off every call and adds a weekly allowance of free tokens.
