Kite is an open-source universal checkout for crypto: one payment link that any person, any wallet and any AI agent can pay, in any token on any chain the merchant accepts, with no custodian in between.
How the universal checkout works: the merchant creates a payment link. A customer connects any EVM or NEAR wallet, or sends from any wallet or exchange; an AI agent pays the same link over x402 with one HTTP request. Kite quotes the swap (Rhea on NEAR, Uniswap on EVM) and gives the payment a one-time address. When the funds arrive, that payment's own contract is deployed, swaps, pays the fee and settles to the merchant, or refunds the customer after expiry. Kite never holds the money.
At NEAR HACKATHON we made NEAR testnet (beta) a chain Kite runs on: one NEP-616 deposit account per payment from a NEP-591 global contract, swaps through Rhea, NEAR wallet checkout, and gasless x402 agent payments where Kite relays the agent's delegated ft_transfer.
The last step is NEAR Intents: the merchant picks one payout token and address, say USDC on NEAR, and every payment's contract settles into a NEAR Intents deposit address that delivers it as that token on that chain, whichever chain the customer paid on.
