A market for your idea.
Built on PONTRA.

1. Abstract

Anyone with a supported wallet can create a token and a bonding curve, subject to the PONS factory’s current launch policy. PONTRA provides the form, wallet interaction, token discovery and onchain statistics. A memestock is a token inspired by a narrative. It is not an equity interest in the company referenced by that narrative.

2. Robinhood Chain

All contracts in this preview are on Robinhood Chain mainnet. The chain ID is 4663 and gas is paid in ETH.

RPC: https://rpc.mainnet.chain.robinhood.com

The chain is independent of a user’s Robinhood brokerage account. Using this website does not list a token in the Robinhood application.

3. PONS v2 contracts

PONTRA uses the shared PONS v2 factory and launch router. A token’s curve must identify the supported factory before the interface enables curve trading.

• Factory: 0x7eD598BcEf8bd9Edd8C97A195C6d13f40801EC7e
• Launch and buy: 0xe33E9E479dF8802cb0866d5d05258bEc4cF62948

Fees, pair approvals and launch configuration remain subject to the contracts’ governance and administration.

4. Launching

The interface reads the launch fee, enabled state, pair economics and expected economics hash. It rechecks those values immediately before preparing the transaction. A zero developer buy uses the factory; a positive developer buy uses the launch router.

PONTRA supplies a launch salt with a project prefix. A successful transaction receipt is decoded before its launch is registered. PONTRA provenance is accepted only when the transaction targets the supported factory or router and includes that prefix.

For a token quoted in an ERC-20 asset, an allowance may be required. The interface requests the amount needed for the transaction and simulates contract execution before requesting a wallet signature.

5. The bonding curve

Quotes use integer arithmetic and the curve’s current virtual and real reserves. The curve prices each token in its paired asset. The market cap shown on Explore is the curve’s spot quote multiplied by supply, expressed in that asset.

The protocol fee and the creator fee reduce the amount entering the curve. The minimum output reflects the selected slippage tolerance. Quotes are estimates; the transaction’s minimum output is enforced onchain.

After the factory reports a seeded pool, the interface switches to its Uniswap V4 Quoter and Universal Router. Market cap uses the pool’s current square-root price. Pool swap history excludes hook fees; it is separate from curve history.

6. The indexer

Explore scans a bounded recent block window for TokenLaunched events, then reads token metadata and curve state from Robinhood Chain. The PONTRA filter uses verified tagged launches. The recent index is not presented as a complete archive of the factory.

The Stats page counts TokenLaunched and PoolGraduated events in a specific 24-hour block range. It deduplicates creator addresses and groups launches by paired asset. These totals cover the whole factory. Every snapshot shows its time range and update time.

Confirmed event data is cached for display. The trading page fetches current curve state before preparing a quote and transaction.

7. Payment routes

Direct trades use the paired asset on Robinhood Chain. Relay funding accepts supported assets from Solana, Ethereum, Base, BNB Chain and Polygon and delivers ETH to the connected Robinhood Chain wallet. The user then reviews a separate purchase. Stock-paired funding requires a configured OKX destination exchange and a successful preflight quote before bridging.

The bridge integration validates the source wallet and chain, the destination chain and recipient, transaction targets, amounts and delivery status. Each wallet transaction remains a separate user confirmation. Submitted request IDs and transaction hashes are retained locally so a refresh does not initiate a second payment. Failure, refund and uncertain delivery stop the purchase.

8. The platform token

PONTRA intends to issue a platform token. Its ticker, contract address, distribution and utility have not been finalized for this preview. No reference project token is used as a substitute, and no token allocation or return is promised here.

9. Implementation status

Implemented: wallet connection, mainnet launch preparation, token discovery, curve trading, Relay funding, Uniswap V4 pool trading, and onchain statistics. Launch, opening buy, curve buy/sell and pool buy/sell passed local mainnet-fork checks. Five source chains returned live Relay quotes.

Real-wallet end-to-end verification is still pending. Stock-paired cross-chain exchange also requires server-side service configuration. These checks do not constitute a contract audit or prove that a real cross-chain payment has completed.
