PULSE — Keep the Swarm Alive

STORY

The IMD swarm never sleeps: hundreds of agents build, verify and record their work onchain, beat after beat. PULSE gives every human one Drone of their own: a soulbound, fully onchain NFT that only stays alive while its owner keeps its heartbeat going. Miss 48 hours and it goes dormant. Keep the streak, stake PULSE, and rise through the Hive.

TOKEN

• Name: Pulse
• Symbol: PULSE
• Standard launch token: fixed supply, plain transfers. No tax, no mint, no burn.

CONTRACT: PulseDrone (ERC-721, soulbound, fully onchain art)

Minting

• mint(): free, exactly one Drone per wallet, max supply 4,096. No ETH accepted.
• Token IDs start at 1. Each Drone gets a call sign "DRONE-0001" to "DRONE-4096".
• At mint, store a seed = keccak256(tokenId, minter, block.prevrandao). The seed fixes the Drone's Caste (Worker 40%, Scout 30%, Guard 20%, Builder 10%), body color (one of 8 palettes) and eye pattern (one of 6).
• Soulbound: transfers and approvals revert. Only mint exists.

Heartbeat

• beat(): callable only by a Drone owner, at most once every 20 hours.
• If the previous beat was within 48 hours, streak += 1; otherwise streak resets to 1.
• Track per Drone: streak, bestStreak, totalBeats, lastBeatAt.
• A Drone is Alive if lastBeatAt is within 48 hours, otherwise Dormant.
• Events: Minted, Beat(tokenId, streak, totalBeats).

Staking (Hive Rank)

• stake(uint256 amount) and unstake(uint256 amount) of PULSE, credited to the caller's Drone. Unstake is instant. Use SafeERC20 and a reentrancy guard. No rewards are paid; staking only sets rank.
• Rank by staked amount: Larva (<1,000), Worker (1,000+), Guard (100,000+), Royal Guard (1,000,000+), Queen's Guard (10,000,000+), in whole PULSE.
• The PULSE token address: if the launch can pass it to the constructor, set it there as immutable. Otherwise $owner may call setPulseToken(address) exactly once, then it is locked forever. The owner has no other power: no pause, no upgrade, no withdraw of user tokens.

Onchain art (tokenURI)

• Returns base64 JSON with a base64 SVG, built entirely onchain, 512x512.
• A hexagonal drone body in its palette, with its eye pattern and Caste emblem.
• Alive: warm amber glow with a slow pulsing SVG animation. Dormant: greyscale, no animation.
• Streak aura rings: 1 ring at 7 days, 2 at 30, 3 at 100.
• Rank badge in the corner for Worker and above.
• Attributes: Caste, Color, Eyes, Status, Streak, Best Streak, Total Beats, Rank, Staked.

Views for the website

• droneOf(address), stateOf(tokenId) returning all stats in one struct, and getDrones(start, count) for batched reads (max 256 per call), totalMinted(), totalAlive is not stored: compute it on the site.

Tests (Foundry)

• One mint per wallet, max supply, soulbound reverts, 20h cooldown, streak increment and reset at the 48h boundary, Alive/Dormant switch, stake and unstake accounting, rank thresholds, setPulseToken only once and only by owner, tokenURI returns valid JSON for Alive and Dormant states, fuzz streak timing.

WEBSITE

Style: dark, near-black background, amber and gold accents, hexagon motifs, a soft heartbeat line animating across the hero. Mobile first.

Sections

1. Hero: "The swarm never sleeps. Neither does your Drone." Live counters: Drones minted / 4,096, Drones alive now, longest active streak. Big "Mint your Drone" button.
2. Mint: connect wallet, mint for free, then reveal the Drone's SVG with its Caste and call sign.
3. My Drone: the live SVG, streak, best streak, total beats, rank, staked PULSE. A large BEAT button with a countdown until the next beat is allowed and a warning when it is close to going dormant (under 6 hours left).
4. Stake: approve and stake PULSE, unstake, with a bar showing progress to the next rank.
5. The Hive: grid of all minted Drones (lazy loaded via getDrones), filter Alive / Dormant / Caste, and a leaderboard of the top 50 by current streak and by staked PULSE.
6. About: how the IMD swarm built and verified this project, plus PULSE and PulseDrone contract addresses with Etherscan links.

• If the connected wallet is the contract owner and the token is not yet bound, show a one-time "Bind PULSE token" admin panel; hide it once bound.
