Contract reference

Every address on every chain. On Base and Robinhood Chain each link opens at the verified code; Arc’s explorer cannot verify source yet, so Arc links open at the address.

The B20 rail

B20 mode launches through its own launcher and hook. Since block 51,697,071 (2026-09-23) that is B20 V6B, which takes any registry-priced pair: the token can sit on either side of the pool, so a B20 against WETH or USDC is currency1.

Launcher, hook and factories are bound immutably in both directions, so any one address proves the rest. RoutedQuoteGate, SwapRouter and PairOracleRegistry carry over from V5. V6 added: split buy/sell tax, dev-buy vesting, the anti-sniper toll, the basket controller seat with renounce-at-launch, and takeover through LaunchControl.

Retired generations

Retired launchers keep working on chain; the platform no longer launches through them, and launches made through them after retirement are not listed.

V4 and V5 rows are the last deployment of each; earlier revisions exist. Read a pool’s hook rather than assuming - any launcher answers hook().

Robinhood Chain (4663)

Deployed 2026-09-04. RhLauncher is a different contract from Base’s V6, built for the chain’s pricing model; the hook is the same AdvancedFeeHookV6.

RhFeeVault	`0x618D78262a8dDE229A088C41C0bFf440aC79D267`

RhPairRegistry admits and prices pairs - the gate. RhFeeVault holds the platform’s cut as USDG. No basket vault, gate lens or routed quote gate: what they serve on Base does not exist here.

The 194 stock tokens are proxies sharing one implementation, admitted by code hash - ask RhPairRegistry.isAdmitted(address). Launched tokens (AdvancedLaunchToken) and distributors (RhHolderRewards) are verified once; Blockscout matches later instances by bytecode.

Arc (5042)

Deployed 2026-09-16. The same RhLauncher and AdvancedFeeHookV6 code as Robinhood Chain, with Arc’s own pair registry and fee vault. Gas and the fee are both USDC.

ArcFeeVault	`0x180767E20B252167637148d35568C0ECc1A1C14a`

ArcPairRegistry admits and prices pairs - USDC through its Chainlink feed, the rest from their own markets. ArcFeeVault holds the platform’s cut as USDC. The swap router is the one prepare_trade and /api/v1/agent/trade/prepare address on Arc.

Linked libraries
