What just happened
Everything you clicked was a real blockchain interaction — and it's all still here, in your wallet. Below: the things you made, each beside the machinery that made it free.
Keys, not accounts
That "Create my account" click generated a keypair in your browser with koilib. The address is derived from the public key. There is no signup because there is nothing to register — on Koinos, holding a key IS having an account.
const signer = new Signer({ privateKey }); const address = signer.getAddress(); // that's it. that's the account.
Mana, not gas
Koinos meters computation with mana — an energy that every KOIN holder has and that regenerates over ~5 days. It can be capped, spent and recharged, but never bought or sold. And crucially: someone else can pay yours.
Every transaction you sent here named two parties: payee (you — your
nonce, your authority) and payer (the gateway's sponsor wallet — its
mana). You signed, the sponsor co-signed, nobody paid a fee. That's not a promo
budget; it's a protocol feature called mana sharing.
new Transaction({ options: { payer: sponsorWallet, // their mana burns (and regenerates) payee: yourAddress, // your nonce, your authority }})
Contracts are accounts
Your art goes into the Discover Koinos Paint collection — a KCS-2 contract. On Koinos a contract is just an account with WASM uploaded to it, and it can act as itself: the collection authorized your free mint with its own signature while the sponsor paid. The image? Stored on-chain, in the token's metadata, as an SVG your grandchildren can still decode.
You deployed a contract
The Token Lab uploaded ~60KB of audited KCS-4 bytecode to a fresh account and
called initialize with your name, symbol and supply. Two real
transactions. On most chains that's a paid, tooling-heavy afternoon; here the
sponsor's mana absorbed it, and the whole supply landed in your wallet.
{ upload_contract: { contract_id, bytecode } } // tx 1
initialize({ name, symbol, decimals, supply }) // tx 2 — yours

This gateway is open source too — fork it, run it, point your community at it. Sponsoring your users' mana costs KOIN you already hold, not fees you burn.
