The direct rail

USDC in, inference out.

USDC on Solana, sent straight to a deposit address from a wallet or an exchange withdrawal. No connection, signing, or account; 0% deposit fee.

On screen before you open a wallet

  • ShownAmount
    AsThe exact figure
    BecauseNo surprise line items appear after you send
  • ShownMint
    AsEPjFW… + verify link
    BecauseCheck the USDC mint yourself before trusting the QR
  • ShownNetwork
    AsSolana, stated plainly
    BecauseWrong-chain sends are the #2 support class; we name the chain
  • ShownMinimum
    As$5
    BecauseNetwork fees eat anything smaller

Any USDC arriving at the address is credited, and partial payments accumulate. If an exchange fee turns your $20 into $19.98, you get $19.98 of credits.

After you send

The pending screen is a real URL; it survives a refresh, a closed tab and a phone lock.

No withdrawalsCredits buy inference only.

Credits buy inference. They are not a withdrawable balance — we are not a money transmitter and do not want to become one, which is what keeps this cheap and KYC-free.

Credits never expireYour balance stays until you spend it.

Expiring credits is a dark pattern. Your balance sits there until you spend it.

$5 minimumSmaller sends are consumed by network fees.

Network fees eat anything smaller. That is the only floor, and it is deliberately low — the first bet on a stranger should be five dollars.

Save both secretsAPI key plus permanent dashboard link.

Accountless setup creates an API key and a permanent dashboard link. The link can replace a lost or rotated key; lose both and there is no personal recovery.

Holding something else? The any-coin rail settles BTC, EVM chains, Tron, TON and XRP into this one.
