Protocol documentation

Rules in plain sight.

Network

Robinhood Chain (chain 4663). Fees and curve reserves use ETH. Connect an EVM wallet; Solana wallets, SOL, SPL tokens and the closed Solana program are not supported by this deployment.

Launch

Launch costs a fixed 0.02 ETH seed plus network gas. One billion ERC20 tokens with 18 decimals are minted into the curve, with no creator allocation and no future minting. The seed cannot be withdrawn by the creator. Metadata URI and treasury are immutable.

Bonding curve

Token output = token reserve × ETH input / (real ETH reserve + virtual ETH reserve + ETH input), rounded down. The virtual reserve is 0.3 ETH: it affects price but cannot pay sellers. A sale is rejected if real backing is insufficient. There is no Raydium integration or automatic DEX graduation.

Paper-hand tax

Every purchase records ETH cost basis. A partial sale uses its proportional basis. If gross sale proceeds are below that basis by more than one wei, 50% of gross proceeds is tax. A one-wei tolerance prevents rounding-only losses from triggering the tax. Net proceeds are protected by your minimum-output setting. Profitable curve exits have no paper-hand tax. Gas is excluded from cost basis.

Transfers and external markets

Wallet transfers carry proportional cost basis. Direct transfers into the curve are rejected; use the buy/sell functions. Transfers and external DEX trades do not levy PHBT tax; external purchase prices are not tracked. This is not universal anti-dump protection.

Treasury and buybacks

Tax stays separately accounted for inside each token contract. The immutable treasury may withdraw accrued tax or spend it on curve buybacks that burn purchased tokens. The treasury cannot withdraw pool reserves. Factory totals track actual collected tax and buyback ETH.

Confirmation and slippage

Quotes are refreshed before signing. A transaction has a 10-minute deadline and a minimum amount received, after tax for sells. Pending transactions show an explorer link. Never submit a duplicate because a confirmation screen timed out.

Profiles and data

Balances, prices, tax and buybacks come from contracts. MongoDB stores chain-scoped watchlists with one-use signed challenges; no private key belongs in the database or frontend. Recent trade charts cover only the last 2,000 blocks. Full historical indexing is not included in this version.

Security and status

This is an experimental EVM rewrite, not an audited production protocol. The contracts are non-upgradeable and have no shutdown or reserve-recovery function. Test all flows on testnet and obtain an independent contract audit before using real money. Existing Solana assets do not migrate automatically.
