Pons V2
The launch fee is 0.0005 ETH, read from launchFee() on the factory, not from the docs.
USDG
The testnet runs on chain 46630 with the same tooling.
Tokenized equities
Claims on shares held by the issuer — not price-tracking derivatives.
Chainlink price feeds
Ninety-five tokenized US equities trade on the chain as ERC-20 tokens.
The canonical bridge
USDG — a 6-decimal stablecoin — is the asset the chain settles in.
Withdrawals
The root is only stored once the assertion is confirmed — before that there is nothing to claim against.
ArbSys
The testnet runs on chain 46630 with the same tooling.
Fees
Deposits from Ethereum confirm in about ten minutes over the canonical bridge.
What is not here
Withdrawals take a 45,818-block challenge period on Ethereum — about 6.4 days.
The explorer
The canonical bridge is the trustless default; the other routes are listed separately and labelled as such.
The chain itself
ArbSys at 0x…64 returns the chain's own height; block.number returns Ethereum's.
Cross-chain routes
Every number on this page can be read back from the chain.
