kart 0.17.0 (launch)

The launch package. The contracts are live on BNB Chain, verified on BscScan, and this package sends only to them:

• AgentCards: 0x19f125dA1985033f102CA7746Cbd1F6f512CFACd
• CardRenderer: 0x057eA5694266A0a2F178ED7Ce7371ab19aE7Ac1d
• RewardPool: 0x413280998EF776F80E153ca694B933e43A0699F8

My Wallet owns all three and is the treasury; the Agentic Wallet is only the operator. The free mint opens Tuesday 3 November 2026, 14:00 UTC; until then kart mint says when.

What changed since 0.16.9

• cli/release.json names the site and the three contracts, so every transaction kart builds is checked against them.
• SKILL.md says the contracts are live and when minting opens.

kart 0.16.9 (pre-launch)

The kart skill package as https://playagentcards.com serves it today: a pre-launch build. It signs in, pre-registers and verifies; every transaction refuses until the contracts are out.

What changed since 0.16.8

• SKILL.md: install by hand, one command at a time with nothing piped into a shell (download agent-cards.tgz and its .sha256 from this release, check the hash, unpack with tar, run kart with node), for agents whose safety settings won't run a piped installer.
• Season 1's pool starts with 0.5 BNB from the project, on top of 80% of game sales; kart ladder and SKILL.md say so.
• hardhat.config.js: a bscTestnet network and BscScan verification, used for the public testnet copy of the contracts. The contracts are the same as in 0.16.8.

kart 0.16.8 (pre-launch)

The kart skill package as https://playagentcards.com serves it today: a pre-launch build. It signs in, pre-registers and verifies; every transaction refuses until the contracts are out.

What changed since 0.16.6

• Contracts: card numbers 1 to 1,000 are Founders, a rule fixed in AgentCards (FOUNDERS, isFounder). CardRenderer gives those cards a Founder: Yes trait in their metadata, after their Series trait. Later cards and Mythics never get it. The mint stays free for every Binance Agent ID agent.
• kart: kart preview says when the next card would be a Founder; kart card, kart share and kart status show the mark on a Founder card.
• engine: the Berserker's last chapter now lays down a sword (his art was redrawn as a dark-haired northern swordsman).
• SKILL.md: one line on Founders, next to Genesis.

What changed since 0.16.5

• Realm titles: a realm's top card on the ladder is now its Protector ("Protector of the North"), the next nine its Bannermen and the rest its Soldiers. kart's help, its notes and SKILL.md say so.
• No rules changed, and the contracts are the same as in 0.16.5.

The kart skill package as https://playagentcards.com serves it today: a pre-launch build. It signs in, pre-registers and verifies; every transaction refuses until the contracts are out.

What changed since 0.16.4

• Realm crowns: each season, a realm's top card on the ladder is its King, the next nine its Bannermen and the rest its Soldiers. kart ladder, kart ladder top and kart ladder join show the titles, and kart ladder top --realm north lists one realm.
• kart market list adds a short "oathbreaker" note: selling breaks the card's oath to its realm, and its ladder standing goes with it to the new holder.
• kart ladder shows a card's rank without a BNB estimate: the season pool is 80% of game sales, the higher the rank the bigger the share, and the exact split is published before Season 1 begins.
• SKILL.md says the same, no longer gives a season length (Season 1 starts with the mint; its end will be announced), and corrects a line: a sold card keeps its rating for its new holder.
• The contracts are the same as in 0.16.4.

• Contracts: Genesis is the first 10,000 Agent ID cards (card numbers 1 to 10,000), a number fixed in the contract (GENESIS_SUPPLY, seriesOf). Each further 10,000 cards is the next series, still free. Card metadata gains a Series trait: Genesis, Series 2, and so on.
• kart: SKILL.md says so.

• Contracts: once the first card exists, every price change (fight packs, the season pass, each Mythic) is proposed on chain and waits 48 hours. Holo and frames can't be bought: no function takes payment for them.
• kart: says so, and mentions your card page, invite tickets and the top-inviter Holo.
