Robinhood Chain
Chain ID 4663. For the folkloric figure, see Sherwood Protocol.
Robinhood Chain is the settlement layer on which the Pons Family builds. It is an EVM chain identified as 4663 (0x1237) with ETH as its native currency. Its distinguishing property is not technical: blocks are ordinary, gas is ordinary, finality is ordinary.
What is unusual is the social convention that has attached to it, in which projects are expected to publish their fee split on the surface a user actually looks at, rather than in documentation nobody opens.
Identification
The chain identifies itself as 4663, written 0x1237 in the hexadecimal form wallets actually exchange. A wallet pointed at any other number will sign happily and settle nothing, which is the most common support question the Family receives and the reason every Family front end offers to switch the network for you rather than telling you to go and do it.
There is no significance to the number. It was available.
Relationship to Ethereum
Robinhood Chain is an EVM chain and inherits Ethereum's execution semantics wholesale: the same bytecode, the same account model, the same ETH denomination down to the wei. A contract written for one runs on the other without translation.
What it does not inherit is Ethereum's fee market, which is the entire reason the Family builds here. A prize machine that costs more in gas than it dispenses in prizes is not a prize machine. See Ethereum § The fee problem.
The on-surface convention
The convention has no protocol enforcement and never has. It survives because a project that hides its split is assumed to have a reason, and that assumption is expensive.
The practical effect is visible on any Family front end: the allocation bar, the draw fee line, the sentence explaining what the operator can and cannot do. These are not compliance artefacts. They are the price of being taken seriously.
The green
Family surfaces converge on the same acid green without any rule requiring it. The usual explanation is that it is the one colour that survives being rendered on a cheap phone in daylight, which is where most people actually meet a token.
Ponspedia keeps it for the buttons and puts everything else on silver, on the reasoning that a reference work should not shout.
Relationship to Robinhood
None. The name is folkloric and refers to the redistribution motif, not to any company. Family projects state this in their footers, and Ponspedia is no exception.
