Binner is a non-custodial interface for creating and trading fixed-supply ERC-20 tokens through a bin-based bonding curve. This page explains what the interface shows, what the contracts enforce and what remains testnet-only.
Wallet authority, selected-network readiness, finalized blocks, reorg depth, preview authority and exact write blockers are centralized so token pages can stay focused on the token.
Open live Status →Your connected wallet owns the account and submits every approval, creation, buy, sell or claim. Binner never receives your private key and cannot reverse a confirmed public-chain transaction.
The contracts define supply, curve traversal, reserves, fees and graduation. The interface prepares calls and explains their state, but the public chain is the authority for execution.
A bin is one slice of the curve's token inventory at one price level. Bin 0 opens at the base price; every following bin is 20% higher than that opening price. One trade can cross several bins and any unused quote is refunded.
The curve choice is saved with the token at creation and cannot be replaced later. Its numeric choice is the durable onchain identity; its profile explains where inventory is concentrated.
| Choice | Profile | Bins | Supply on curve | Terminal price |
|---|---|---|---|---|
| #1 | Flat 20Equal capacity on every bin: each holds the same number of tokens. Clearing a bin still costs more quote than the one before it, because its price is higher — only the token quantity is constant. | 20 | 62.33% | 4.8x |
| #2 | Ascending 19Capacity rises toward the higher prices. The early bins are thin, so the first buyers move the price furthest, and of the four deployed curves this one demands the most quote to graduate. | 19 | 59.84% | 4.6x |
| #3 | Descending 19Capacity concentrated on the first bins. The cheapest quote target of the four deployed curves, and the one that puts the most supply at the opening price. | 19 | 64.67% | 4.6x |
| #4 | Hump 21Peak capacity in the middle. Its percentOfCurve divides exactly, so the pool opens at exactly the terminal bin price with no rounding shortfall at all. | 21 | 62.50% | 5.0x |

70% is claimable by the creator; the remainder goes to the protocol recipient. Governance cannot exceed 2.50%.
The token's recorded quote reserve and remaining liquidity allocation are handed to the frozen venue adapter.
Venue ID 3 is the registered Binner Uniswap V4 adapter on Robinhood Testnet. It initializes or reuses the exact pool and creates a full-range liquidity position. The position stays held by the adapter with no Binner withdrawal or fee-collection path.
Graduation is atomic: if the adapter call or its measured postconditions fail, the terminal buy reverts. The token page records the venue, opaque pool identifier and graduation transaction when indexed.
Account, wallet network, balances, allowance, simulation and receipts are checked through the connected wallet provider before a write. A stale preview or changed account/network is discarded before signing.
Catalogue, tokens, trades, holders and graduation history come from the finalized read model. The Robinhood pipeline separates 25-block confirmed data from its 240-block finalized and recoverable-reorg boundary, so the interface can lag the chain and says so instead of inventing fresh data.
Robinhood Testnet has a reviewed Binner factory and a completed canary lifecycle. Arc Testnet remains read-only in this interface and Arc Mainnet is unresolved. None of this is an independent audit, a Robinhood or Uniswap endorsement, or approval for a mainnet deployment.
Tokens are experimental and can lose all value. Verify the selected network, contract, amounts, slippage, deadline and wallet simulation before every signature. Binner provides no financial, legal or tax advice.
