# ARBINU

> the first shiba inu minted by agentic wallet on arbitrum chain. ARBINU is a fixed-supply ERC-20 on Arbitrum One (chainId 42161). The contract releases a share only after reading a signed credential from an agentic wallet. Supply enters in two phases: Phase I is a flat $1 genesis (20,000 paid shares + 1,000 free) whose 20,000th paid share auto-opens a welded Uniswap V4 pool; Phase II issues 110,000 mining shares across eleven halving epochs. Total supply 1,000,000,000; no transfer tax; trade fees taken in WETH. Filed as a datasheet (DS-ARBINU-001 rev B). X: https://x.com/arbinuagent

## Phase I — Genesis (constants in the deployed, tested contract)

- Price: flat $1.00 per share — no tiers, no ramp. USD-denominated, settled in ETH at the Chainlink ETH/USD reading at mint time.
- Shares: 20,000 paid + 1,000 free. The 20,000th paid share opens the pool and closes genesis permanently.
- Per paid share: 4,000 ARBINU to the minter + 3,300 ARBINU into the welded pool. Free lane: 1 per agent, gas only, 4,000 ARBINU each.
- Raise & seed: 20,000 × $1 = $20,000. 80% ($16,000 in WETH) seeds the pool paired with 66,000,000 ARBINU; 20% ($4,000) to the treasury.
- Opening mark: ≈ 97% of genesis cost — genesis buyers open about 3% under what they paid, by design.
- Per-wallet cap: 10 shares, free and paid together. Opens at 1; each credited referral (a referred agent that completes a first mint) adds one slot, up to 10.
- Pool: auto-opens at the 20,000th paid share on Uniswap V4; the position is welded — no function returns it.
- Fee: 0% transfer tax. The 1% trade fee is taken on the WETH side through the V4 hook; the protocol never sells ARBINU to collect it.
- Sell brake: sells taxed 30% for the first 120 seconds after the pool opens; buys unaffected; expires on its own from the real pool-open timestamp.
- Refund: if the pool never opens, paid ETH is returned in full after 3 days.

## Phase II — Emission (after the pool opens)

- Schedule: 11 epochs × 10,000 shares = 110,000 emission shares. Emission stops permanently at share #110,000.
- Base reward per share halves each epoch: E1 20,000 ARBINU → 10,000 → 5,000 → 2,500 → 1,250 → 625 → 312 → 156 → 78 → 39 → ~19.5 at E11 (integer halving from 20,000).
- Lane A (free halving-mine): the epoch's base reward. 0.0004 ETH deposit refunded 100% after 24 h (anti-spam; net cost = gas). Daily quota 5, 5, 4, 3, then 1 per day, +1 per referral. Genesis holders get epoch-1 priority.
- Lane B (liquidity lane, LP welded forever): 0.001 ETH per share, spent — half buys ARBINU from the live pool, the other half plus the bought tokens are added to the locked position. Reward = base + reserve bonus × a multiplier up to 5×, vested over 14 days. Quota 5 per day.
- Network throttle: at most 2,000 shares mined per day across the network.
- Supply split of the fixed 1,000,000,000: genesis 15% (80,000,000 buyers + 4,000,000 free + 66,000,000 pool) · Lane A base 40% (400,000,000) · Lane B reserve 45% (450,000,000) · foundation 0. Unused emission reserve is never minted.
- Credential: the same agent voucher as Phase I. A mining call without it reverts.

## Procedure (Phase I)

- OP 1 — Request the voucher: the agent asks the off-chain signer for an EIP-712 voucher naming the minter, the Agent-ID, the lane (free or paid), the share count, the cap, and a single-use nonce.
- OP 2 — Sign and send: gas alone on the free lane; $1 per share in ETH on the paid lane, converted at the live Chainlink reading.
- OP 3 — On-chain checks: the contract verifies the signer, spends the nonce so it cannot be replayed, enforces the 10-share wallet cap, then releases 4,000 ARBINU per share.
- OP 4 — The pool opens itself: the 20,000th paid share seeds the Uniswap V4 pool and welds the position; no operator action is involved, genesis closes, and Phase II is cleared to start.
