A shiba inu, filed as a part. ARBINU is a fixed-supply ERC-20 on Arbitrum One. The contract releases a share only after reading a signed credential from an agentic wallet. Supply enters in two phases: Phase I registers 20,000 paid shares at a flat $1 (plus 1,000 free) and the 20,000th share opens the pool; Phase II issues 110,000 mining shares across eleven halving epochs. Every value on this page has a tolerance, and the tolerance is zero.
Two phases draw from one supply. Every value below is a constant in the deployed, tested contract and has no admin setter. The numbers are final.
| Token / chain | $ARBINU · Arbitrum One · chainId 42161 |
| Total supply | 1,000,000,000 — fixed. The mint contract is the sole issuer and halts at the ceiling |
| Phase I shares | 20,000 paid + 1,000 free. The 20,000th paid share opens the pool and closes genesis permanently |
| Genesis price | Flat $1.00 per share — no tiers, no ramp. First share and last share cost the same |
| Per paid share | 4,000 ARBINU to the minter + 3,300 ARBINU into the welded pool |
| Free lane | 1,000 shares — 1 per agent, gas only, 4,000 ARBINU each |
| Settlement | USD-denominated; settled in ETH at the Chainlink ETH/USD reading at mint time (stale-feed and sequencer checks on) |
| Per-wallet cap | 10 shares, free and paid together. Opens at 1; grows by one slot per credited referral — referrals |
| 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. A hair below cost, not a cliff |
| Pool | Auto-opens at the 20,000th paid share on Uniswap V4. The position is welded: no function returns it |
| Trade fee | 1%, 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 |
| Refund | If the pool never opens, paid ETH is returned in full after 3 days — refund |
| Mechanism | Once the pool is live, agents mine ARBINU in shares. Each epoch issues a base reward per share; the next epoch issues half of it |
| Precondition | The 20,000th paid genesis share has opened the pool. Until then, emission is inert |
| Epochs | 11 epochs × 10,000 shares = 110,000 emission shares. Emission stops permanently at share #110,000 |
| Base reward | E1 20,000 ARBINU per share → 10,000 → 5,000 → 2,500 → 1,250 … → ~19.5 at E11 (integer halving from 20,000) |
| Lane A · free mine | The epoch’s base reward. A 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 | 0.001 ETH per share, spent: half buys ARBINU from the live pool, the other half plus the bought tokens are added to the welded 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. Emission paces over weeks, not hours |
| Supply split | 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. Any unused reserve is never minted |
| Credential | The same agent voucher as Phase I. A mining call without it reverts |
One price for every share: $1.00. The 20,000th paid share closes genesis and opens the pool in the same transaction. Eighty percent of the raise becomes the pool’s WETH side, paired against 66,000,000 ARBINU, so the opening mark lands about 3% under genesis cost — close enough to cost that there is no cliff to fall off.
When the pool opens, Phase I hands over to Phase II. Agents mine 110,000 shares in eleven epochs of 10,000. Epoch 1 pays 20,000 ARBINU per share; every epoch after pays half the one before, down to about 19.5 at epoch 11. Then it stops. The schedule is written into the contract.
20,000 → 10,000 → 5,000 … → ~19.5. No flat drip, no manual top-up, no twelfth epoch.
Emission is inert until the 20,000th paid genesis share opens the pool. Genesis holders get epoch-1 priority.
At most 2,000 shares are mined network-wide per day, so 110,000 shares take weeks, not an afternoon.
Genesis 15% + Lane A 40% + Lane B 45% = 1,000,000,000. Whatever the reserve does not pay out is simply never minted.
Four operations. The agent performs them; the contract checks each one. A failed check leaves state untouched.
The agent asks the off-chain signer for a voucher. It names the minter, the Agent-ID, the lane (free or paid), the share count, the cap, and a single-use nonce.
The wallet signs and submits — gas alone on the free lane; $1 per share in ETH on the paid lane, converted at the live Chainlink reading.
The contract verifies the signer, spends the nonce so it can’t be replayed, enforces the 10-share wallet cap, then releases 4,000 ARBINU per share.
The 20,000th paid share seeds the Uniswap V4 pool with $16,000 of WETH against 66,000,000 ARBINU and welds the position. No operator action; the counter triggers it, genesis closes, and Phase II is cleared to start.
A printer, a drain valve, a fee wallet full of the token — the usual failure points of a meme coin. ARBINU’s contract has no such parts. You can’t open a valve that isn’t there.
At opening, the LP position is locked, and Lane B only ever adds to it. The contract contains no function that returns it to any address.
The 1% trade fee is skimmed on the WETH side and sent to the treasury as WETH. The protocol holds no ARBINU inventory to sell.
A 30% sell tax runs for exactly 120 seconds from the real pool-open timestamp, then expires. No admin switch exists.
Escrow becomes locked liquidity when the 20,000th share opens the pool, or is returned in full after 3 days if it never does.
Minting requires a Binance agentic wallet able to present an Agent-ID. The backend signs an EIP-712 voucher; on-chain, the contract verifies the signer, ties the voucher to the sending address, and spends the nonce. A call that arrives without a valid voucher reverts before any state changes.
